Dong Feng (East Wind) DF-104, DF-107 and DF-113 Fighters
« on: January 12, 2006, 05:48:55 am »
There are some fighters which were initially designated by some sources as Dong-Feng fighters: the Shenyang J-6 MiG-19PF and MiG-19SF were also known as Type-59 and later called Dong Feng 102 (DF-102). This initial Dong Feng fighter was followed by two other East Wind fighters based on the MiG-19: A MiG-19PF derivative with a limited all-weather capability was called Dong Feng 103 but also known as Type 59A and the MiG-19PM all weather version, which was build by Nanchang. Its initial designation was Dong Feng 105 or otherwise Type 59B.

The first real indigenous East Wind series fighter was the DF-104 and seems to have been under development in between the DF-103 and DF-105 MiG-19 derivates. Not much is known about this project only that it remained a real “paper project”, which was designed by the Shenyang Aircraft Factory (not the Shenyang-based 601 Aircraft Design Institute) with Soviet help but not as a copy of a Soviet design. The DF-104 was designed as a Mach 1,4 capable fighter using design elements of the latest fighters and it could be assumed that it was to be powered by two maybe up-rated WP-6 turbojet engines as used by the J-6 and Q-5. Its development started about the end of 1957 or beginning of 1958 only to be given up in favour of an enlarged version of the DF-104 called DF-107 a few months later.

This design was suggested when the Aviation Industry Control Section insisted early in 1958 on much higher performance especially for a top speed of Mach 1,8 at a service ceiling of 20.000 m. The design of the DF-104 started in 1958 and already some form of prototype construction had begun in May 1959, when only one month later the concept needed some significant modifications.

Of the many novel technology used for the DF-107 was a variable angle of attack wing design similar to the F-8 Crusader or some of the Mikoyan Ye-series fighter prototypes. Otherwise this fighter closely resembles a twin engined Starfighter fuselage with a standard tail and sharply ranked wings. The two engines were to be fed by two lateral air intakes and seem to have been much improved and up-rated engines derived from the WP-6 called “Hong Qui-2” (“Red Flag-2”). This was the second indigenous turbojet designed by the Shenyang Aeroengine Design Office (SADO) following the initial success of the PF-1A developed for the JJ-1. Even after early ground test runs seem to have been successful or at least quite promising, it was once again decided to stop all development work on the engine and the fighter itself from November 1859 on and to develop another engine called “Type-814” for the next project the DF-113.

The design of the DF-113 was under development by the Military Engineering Academy in Harbin and promised to be a true high attitude and high speed all-weather fighter with a required speed of Mach 2,5 at a ceiling of 25.000 m. Once again this fighter was an indigenous design using design elements of the latest US fighters and bombers like the F-104, F-105 and B-58 as a pattern. Sadly not much more than a sketchy three-side-drawing and some other equipment data is available: This fighter had an area-ruled fuselage, a standard tail arrangement and two sharply ranked wings not un-similar to the later Mirage F1. It was planed to be fitted with a powerful intercept radar and modern onboard computer. Two lateral air inlets with a Mirage-like conical centre-cone were planned to feed one not further specified “Type-814” turbojet engine and some sources state that an additional second Powerplant was to be installed in form of a Type-636 rocket engine for additional thrust, but this could not be confirmed.

In the end the project was finally abandoned – like its two predecessors – because of technical difficulties regarding the engine issue and especially the problem related to the so called “heat barrier”.

What followed was once again a license manufactured Soviet fighter in the form of the Mikoyan Mig-21 which formed not only the backbone of the PLAAF’s fighter regiments for the years to come but also the basis for the next and first successful indigenous fighter project: the Shenyang J-8.

I don't believe every secret Chinese Project, but "most" which were mentioned somewhere in open sources. My largest wish / desire however would be, to have a long look into the archives of Chengdu, Shenyang ...  ;D.

Maybe it's just me, but the East Wind TF-113 sure looks to resemble an advanced verion of the HF-24 "Marut".

Imperial guard fighter - take US-make F-8 " crusader " as reference east wind 107 fighter planes


Imperial guard fighter
- take US-make F-8 “crusader” as reference east wind 107 fighter planes
rainbowbear



in January, 1956, the Central Committee of the CCP convention intellectual problem meeting, Secretariat of the Central Committee of the Communist Party of China Secretary Zhou Enlai has done "about Intellectual Problem Report", originating “marches to the science” the summons to the party and the whole nation. Afterward the nation has started “marches to the science” the upsurge. After national science program meeting, our country aircraft industry resolved that goes out mimics the Soviet aircraft's aspect simplex according to the Soviet blueprint, develops our country own Aircraft Design strength.
The aviation industry bureau resolved that establishes the first aircraft design office, the initial period by the Shenyang Aircraft plant substitute management, and adjusts four people from the air bureau: Aircraft technology Section Chief Xu Shun Shou, senior engineer then yellow will thousand, after as well as founding of the nation, from the university aviation is graduation Gu Songfen and the regulation often. The people facing the prosperous development the enterprise, had filled the undertaking great ambition at that time.
The new design's aircraft cannot be “follows a model” to the overseas aircraft the imitation, also makes some “the minor repair slightly modifies” the piece of work, but embarks from aircraft's mission demand, chooses the appropriate method from the world technical aeronautics main storehouse, crosses “the project to be comprehensive” forms own design. This is new China from designs the design path which the first aircraft starts to establish, is also the main design path which the world aviation development follows.
The first aircraft design office design's first aircraft to annihilate teaches 1, as soon as aircraft's population design drawing just completed, instantly enters the actual project approach. This time the factory just mimicked the successful Soviet Union's Mig - 17 jet fighter planes, comes the designers from the factory to be right “the Mig type aircraft” to be familiar. But, the first aircraft design office does not prepare which to let China independently design the aircraft becomes “the Mig computer” the replica. Xu Shun Shou proposed especially for this reason: “must be familiar with Tang poem 300”, namely should be familiar with each kind of different aircraft, then carries on the choices, does not want “only the Mig theory” absolutely, do not design one kind “the Mig computer” anomalous form.
Afterward annihilated teaches 1 to select the US English side mounted air ducts method, but was not the Soviet tradition nose air admission arrangement. Because in the long run, the nose section is suitable in installs antenna's best spot, but the radar in regard to the modern operational aircraft is extremely important. Even though the trainer aircraft does not need to install the complex radar, but controls this kind of side mounted air ducts the design technique to have the use very much in regard to the development high performance service airplane.
at the beginning of 1958, independently designed the manufacture after China to annihilate teaches 1 deployed, have not waited to fly the nose to fly, the first aircraft design office under the Soviet Yakovlev Designing bureau expert Mar article's help, the fermentation independently designed aircraft's next target, made great strides forward to the supersonic jet fighter plane.
in April, 1958, the aircraft design office proposed that the design east wind 104 fighter plane's tentative plans, aircraft's design value is for the maximum level speed Mach number 1.4, the ceiling 17000 meters, the climb rate is bigger than for 70 meters/seconds, the range 1000 kilometers, a cruise duration 1 hour 20 minute, aircraft's power unit uses a Soviet-made рд-9 б turbojet engine, has all-weather operational capability.
But in just the past in March, 1958, Air Force commander Liu Yalou required to design one kind to be able the attack plane which attacks to the place, this computer is called east wind 106, the schematic diagram often waits by the regulation the human to complete in Shenyang. Because later 112 factories must research the east wind 102, east wind 107, east winds 113, afterward must mimic Mig - 19S, therefore the east wind 106 transferred 320 factory research and developments, simultaneously in the Shenyang first aircraft design office qualifications old Engineer Lu Xiaopeng will adjust Nanchang to work.
in May and June, 1958 between, the design team started to inquire into improves the east wind 104 design speeds. on August 6~15, 1958, the aircraft industry technical meeting convened in Shenyang. This is after annihilating teaches 1 test flight success, plans an ideological mobilization and the population which independently designs to the Gauguin broad technical aeronautics field development disposed, simultaneously at the meeting proposed surpasses the world advanced level the design program, resolved that improves the east wind 104 design indices to the Mach number 1.8, the ceiling 20000 meters, the new model is called east wind 107.
The east wind 107 plans use 2 new research and developments the Red Flag 2 jet engines, in the entire distribution refer to American Chance Wort company's F-8 “the crusader” the ship-borne fighter, including F-8 to adapt the shipboard rise variable incidence wing.
] 958 year in August, the east wind 107 predesigns complete basically. The min first miny Mach build understood ha the war industry east wind 113 indices achieve “the pair 25” after situation, then leads aircraft industry Bureau Chief Wang Xiping, assistant commissioner the oil river, Xu Lu Yu, Li Zhaoxiang, Shenyang Aircraft plant Manager Niu Yinguan, Chief Engineer Gao Fangqi, aircraft design office Xu Shun Shou, the yellow will thousand, leaves honorable and so on to go to the Harbin Military engineering Institute to hold on-the-spot meeting. Carries on the visit to study. At on-the-spot meeting, ha the war industry did on the east wind 113 design proposals introduced in detail that comrades attending the forum has carried on the discussion. Finally, the min first miny Mach build said in the speech: The institute dares the spirit which wants to dare to do is good, but the realism has been short a point, a romanticism many point. And said that we must set up the opposite. Afterward in east wind 113 fighter planes “pair 25” under the high index influence, the east wind 107 maximum velocities improve to the Mach number 2.
When convention east wind 113 fighter plane plan examining committee, management's representative proposed that with its dispersion energy, was inferior the east wind 113 and the east wind 107 merges, researches one kind of l.8 a Mach fighter plane. This has evoked the intense discussion at the meeting, finally makes two project both on the conclusion. After the meeting, Chen Geng opposes this matter, thought that “two both do, also does inadequately. Can do one advanced only, cannot do backwardness”. This opinion is accepted by Peng Dehuai, therefore has cancelled the original meeting conclusion. Therefore in October, 1958 reported in the central report to mention the east wind only 113. However, the east wind 107 plans already started and have made certain progress, if 113 suspended as a result of the east wind, rather was a pity. Although therefore holds the examining committee once more which manages by air force Commander Liu Yalou, at the meeting has the argument, but the conclusion is agreed east wind 107 continues the trial production, and authorizes by the national aviation trial production group's name.
This resolution caused at that time the east wind 107 design teams to dance with joy, as a result of its preparatory work development early, as soon as therefore by the higher command to authorize, the experimental work comprehensively unfolded, the very quick blueprint comprehensively originating and starts the experimental work.
in December, 1958, the Shenyang aircraft design office completed the east wind 107 working drawing designs basically. Afterward acts according to the protocol which, Soviet decided that on February 27, 1959, led by aviation industry bureau Assistant Commissioner Xu Changyu, the leaf honorable and so on designers brought the east wind 107 blueprint informations to go to Soviet to consult. At the same time, also escorts to the east wind 107 models Soviet Union to catch a chill. The original east wind 107 takes one kind of our country the new fighter plane which researches, not only the measures of performance are high, and has used many new technologies, therefore should strictly encryption to the Soviet, avoids Soviet Union knowing our country's this new model. However 107 compares the east wind 113 indices with the east wind to be higher, therefore the east wind 107 pieces can attain Soviet Union to catch a chill. The east wind 107 technical advisory works carry on about 8 times, to in September finished in the same year. In the consultation detected that the design proposal has the significant technical question, is mainly the velocity cannot achieve, the drag estimated has been small, this was because the angle of attack variable wing intensity reduced causes, the aircraft performance could not meet the predetermined requirements. Moreover more importantly Soviet Union continually side mounted air ducts this already in annihilated teaches on 1 to succeed the utilization air admission topological design also to deny, Soviet Union is called the length is smaller than 20 meters aircrafts is not suitable for with the side mounted air ducts. The basically east wind 107 to changes from the side mounted air ducts the angle of attack wing by the Soviet total repudiation. However corresponds with it was enlarges the design in PД-9Б the engine foundation the Red Flag 2 engines to obtain Soviet's affirmation.
This situation after in June report aviation industry bureau, in August, authorizes by min first miny Mach build minister, the aviation industry bureau resolves the stop trial production east wind 107, but the design modification work still continued to carry on. Engine's experimental work also continues to carry on.
after in January, 1959 sent the east wind 107 trial production blueprints, in February ~ in May, the aircraft design office modified to the blueprint examination, in the same year in May, originating after has modified blueprint east wind 107 A, new east wind 107A has cancelled changes the angle of attack wing design, changed the stationary triangle high wing, but preserved side mounted air ducts this design. After the modification aircraft needs to carry on the blowing, however at that time our country only then the HK-2 transonic wind tunnel which imported from Democratic Germany. However to catch up with in October 1, 1959 offers a gift, the aircraft hurried caught a chill. Because afterward the expectation use's Red Flag 2 engines complete with difficulty according to the plan, the aircraft design office also modification designs east wind 107S (power to change to the Soviet PД-9Б engine). In September, has designed in the same year the east wind 107Z tactic reconnaissance aircraft according to the factory party committee's resolution, simultaneously as 107A testing machine. Later has designed transition plans and so on east wind 107J ground attack trainer aircraft, has not put into the trial production.
But takes uses the side mounted air ducts topology similarly the east wind 106, after changing to 320 factories, renamed eagle 302, Lu Xiaopeng has made the improvement to the initial design, like used the area law the aircraft body, lengthened computer the nose cone, after using, operated the type cockpit cover and so on, caused this computer development famous 5 attack planes.
As for has the future to spread the wings very much originally the blue sky east wind 107, has made the full size wooden model, after merely then stopped the development. However the essential road must walk, in east wind 107 triturating, although the road is rough, but gained in the substantial experiences. Afterward our country's designers are having a thorough understanding in thoroughly the Mig - 21 aircraft foundations, the success researched advanced has annihilated the 8II upper air superfighter.

http://military.china.com 2005-11-24 17:42: 58 [major and medium small]

  
  in March, 1958, the aviation industry bureau established the aircraft industry 15 year development summary, stressed that China aircraft industry production, the scientific research were also very backward, must make haste to catch up, makes utmost effort 15 years close then international advanced to be originally even;

  on March 25, 1958, the aircraft industry convention Aircraft plant the leading cadre meeting. Air force Commander Liu Yalou published the air force to support the aircraft industry at the meeting to do the scientific research design with all one's strength the important speech;

  on May 7, 1958, the aviation industry bureau reported to the Central Committee of the CCP: In the current aircraft industry build's principal contradiction is the product design and the scientific research falls behind by far the production;

  on July 26, 1958, our country independently designed the manufacture the first jet trainer aircraft to annihilate teaches 1, the initial test flight was successful;

  in August, 1958 6 to 15th, the aircraft industry technical meeting convened in Shenyang. This is after annihilating teaches 1 test flight success, plans to the Gauguin broad technical aeronautics leads an ideological mobilization and the population disposition which the load development independently designs;

  in August, 1958, the Shenyang aircraft design office started to design the supersonic fighter plane officially “the east wind 107”;

  on October 13, 1958 the central official authorization researched the supersonic fighter plane which the Harbin Military engineering Institute proposed “the east wind 113”. Hence, our country Great Leap Forward time aircraft industry's best quality goods, “the east wind 113 “deploys officially.

  The project plan allocates funds 60,000,000 Yuan, from starts to conceive flies to, uses 10 months only!

  “the east wind 113” is the air defense of the homeland and the frontline combat dual purpose fighter plane, began in 1958 most early about this computer tentative plan the spring. Conducts in the Harbin Military engineering Institute works and studies in the active procedure, the air force engineering department teachers and students proposed that “the relation actual carries on the graduation project, completes one kind of new style fighter plane together”, this idea obtains Chair Chen Geng to support and the air force Commander Liu Yalou's approval.

  “the east wind 113” the initial project objective is, the maximum level speed amounts to 2 Mach, more than the ceiling 20000 meters, later according to science committee's opinion, changed 2.5 Mach and the ceiling 25,000 meters - namely “the pair 25” the index. Its operational target for US's F-104, F-105 fighter and B-58 supersonic speed bomber. The requirements when battle with above two kind of fighters, holds the capability superiority, then interception bomber target.

  In the same year, many national leaders arrive at ha the war industry to observe successively, and represented support “east wind 113” the tentative plan, the air bureau also gave the modification comment to the plan. Therefore, bold “the ultra level” the project starts to start officially. Started from March, 1958 to ferment, plan in September completed the system design, in October to central submitted “about the trial production new fighter plane's report”, strove for in January, 1959 the test flight. The project plan allocates funds 60,000,000 Yuan, from starts to conceive flies to, uses 10 months only!

  Regardless of looked from that kind of angle, “east wind 113” the capability criteria at that time were extra-superior.

  “the east wind 113” the complete machine designs uses the side mounted air ducts the non-Eastern tradition topology, this is to load the radar, undertakes the long-range interception mission natural selection. (the radar technology was not mature, the Soviet aircraft did not install the high powered radar generally on the aircraft, therefore was accustomed to selects the air admission efficiency maximum nose air admission method. But at that time the Chinese aeronautical circle proposed that “is familiar with Tang poem 300, but do not do only the Mig theory” - one, in annihilates teaches in a 1 research and development, selected two example air admission method boldly, the fact had proven that this computer research and development was successful)

  


  East wind 113 imagination charts
  “the east wind 113” uses the monocoque prolate body, computer the identity 3 sections, for convenience safeguarding, in which, the latter two sections may facilitate disassemble, between aircraft body and engine through importing air current heat insulation.

  In order to implement this computer high speed capability, the wing has used the angle of sweep-back 50O big arrow-head wing, the wing section selection supersonic flight drag small “the tip point tail thin airfoil”, thickness ratio 5%. On the wing sets up 3 wing fences, the trailing edge inside has the backlash type dehiscence flap. The vertical stabilizer area is very big, guarantees aircraft's in high-speed flight time stability, its angle of sweep-back 575”. The tail plane to all move the type, the angle of sweep-back 55”.

  In order to implement “the pair advanced 2.5” the index, this maneuverability system is unique, is not only loaded with a belt thrust augmentation in fuselage “814” the turbojet engine (thrust augmentation thrust 11,000 kilograms), but also equipped has sped up to boost uses “636” the liquid-propellent motor (in 18,000 meters heights, thrust 1,200 kilograms, service life surpassed 10 times), so when could need the instantaneous acceleration or the jump offers the extra power support, suited in the air fight “to snatch the position to account for the height”. Above two different type's engine uses the TC-l aviation coal painter's shop fuel, has avoided the design and the logistics complication.

  In view of the fact that the upper air high speed operational environment's actual requirements, this computer have used the seal turbo-charged -like single cabin, simultaneously the cabin has prevents below 280 nanometers wave lengths ultraviolet's ability (to avoid the upper air solar radiation), the wind shield glass uses spurts the ethyl alcohol anti-icing the method. In the cabin is equipped with the ejection lifesaving chair and the supersonic ejection protective equipment, safeguards the pilot more than highly 70 meters, more than the speed 400 kilometers flies when parachuting safety. This computer simultaneously equips the autopilot and the manual control system, two set of control system crossing linking, momentarily may carry on toggles.

  “east wind 113” airborne navigation electricity facilities besides ordinary measuring appliance, but also provides in the advanced/velocity to admire, the self-guided highly systematic and the radio navigation system. The airborne air-interception radar's operating altitude range is 1,900~25,000 meters, to the large-scale bomber's probing range is 23 kilometers, the tracking distance is 17.3 kilometers; To the fighter plane probing range is 11 kilometers, the tracking distance is 8.6 kilometers.

  “east wind 113” the weapon system by the air-to-air missile, the aerial cannon, moves the punmetals mounting, composes with the primary fire control electronic accounting machine. Two air-to-air missile range 10 kilometers, bullet weight 150 kilograms, length of projectile 2.5 meters; 1 30 millimeter caliber 6 aerial cannons, total weight 160 kilograms, rate of fire 8000 round of/score, maximum range 3,000 meters, bullet weight 0.84 kilograms/round.

  In brief, regardless of looked from the software or the hardware, “east wind 113” the capability criteria at that time were extra-superior.

  During factory two major issue research and developments, add the personnel and in the dispatcher control contradiction obviously

  When this computer design uses “side designs, trial produces, produces” the guidelines, ha war industry's designers arrive at the factory one after another, the technical personnel carries on the research and development work together with the factory, for this reason, the factory established has been responsible for “the east wind specially 113” the project second design office. But because the factory originally already has undertaken “the east wind 107” the trial production mission, now has joined “the east wind 113”, carries on two major issue research and developments with the factory, in whose problem has pulled first after who, contradictory is not clearly incisive, the experimental work is at half stop state. Therefore, the trial production leading group holds the meeting on November 14 to talk over, has further clarified the guidelines which “the east wind 113” gives priority to development.

  Is right “the east wind in this 107” the situation to make the following introduction.

  


  East wind 107 models

  “the east wind 107” the project begins in “the east wind most early 104”. in March, 1958, our country under the Soviet expert's help, proposed that individually develops one kind of light frontline fighter plane, its maximum velocity is about 1.4 Mach, this is “the east wind 104” the project. To in May and June, the design team starts inquires into improves “the east wind 104” the design speed in the same year. In August, the aircraft industry administrative bureau held the technical meeting, at the meeting proposed surpassed the world advanced level the design program, resolved “east wind 104' the design index improved to the l.8 Mach, the ceiling 20,000 meters - this new model is “the east wind 107”.

  “the east wind 107' the plan uses 2 new research and developments “Red Flag two” the jet engine, in the entire distribution refers to American Chance Wort company's F-8 fighter, and has also used F-8 to adapt the shipboard rise angle of attack invariable high wing.

  When convenes “the east wind 113” the fighter plane plan examining committee, management's representative proposed that with its dispersion energy, was inferior “the east wind 113” and “the east wind 107” the merge, will research one kind of l.8 Mach fighter plane. This has evoked the intense discussion at the meeting, finally makes two project both on the conclusion. After the meeting, Chen Geng opposes this matter, thought that “two both do, also does inadequately. Can do one advanced only, could not do backwardness” this opinion to accept by Peng Dehuai, has cancelled the original meeting conclusion. Therefore in fore-mentioned in October, 1958 reported in the central report to mention “the east wind only 113”.

  However, “the east wind 107” the plan already started and has made certain progress, because if “the east wind 113” suspended, rather was a pity. Although therefore holds the examining committee once more which manages by air force Commander Liu Yalou, at the meeting has the argument, but the conclusion is agreed “east wind 107” continues the trial production, and authorizes by the national aviation trial production group's name.

  This resolution caused at that time “the east wind 107” the design team danced with joy, as a result of its preparatory work development early, therefore a Qi higher command authorized, the experimental work comprehensively unfolded, the very quick blueprint comprehensively originating and starts the experimental work.

  According to the China and Soviet Union related cooperative agreement, on February 27, 1959 the Chinese side brought “the east wind 107” the blueprint information to go to Soviet Union to consult, simultaneously also escorted to the model Soviet Union to catch a chill. The Soviets detected that the design proposal existence major issue, is mainly the angle of attack variable wing is unstable, the drag estimate is too small, the intensity cannot meet the requirements. To in the same year in August from, by authorization, “east wind 107” experimental work stop. In its research and development period, but also once had proposed refits the RD-9B engine (Mig 119 use engine) “east wind 107s”, tactical reconnaissance “east wind 107Z” and trainer version “east wind 107J” and so on modifications.

  The plan postpones repeatedly, the most basic reason is designs the index has the very great distance with our country aircraft industry existing technology and the craft production water buffalo.

  “east wind 107” in discontinuing process, “east wind 113” the experimental work is also carrying on, although has met some technical question and the material problem, but the factory two design offices already merged, the coordinated situation starts to change for the better. “814” turbojet engine structure drawing after redesign completed in February, 1960; The radio altimeter, the beacon rangefinder, the ultrashort wave broadcasting station in also made the prototype to carry on the test flight (in other aircraft types); 20 many kinds of electric fittings issued the design requirements in the normal temperature; The airborne electronic accounting machine may under the room temperature condition the continuous working 3 hours; The airborne 6 artillery research and development has also made the progress ......

  on April 5, 1960, the trial production leading group held the fourth meeting in Beijing, soon researches to the first several month quick work progress and the part special-purpose material expresses satisfaction successfully, thought that the experimental work basic conclusion's, is changing over to the experimental stage. This time, the most difficult material problem appeared -, because the aircraft maximum velocity has surpassed the thermal barrier, must research the heat-resisting new material. If by the available data substitution, the aircraft performance will drop to 1.8 Mach and 11,000 meter ceilings, but waited for that the new material will research successfully, needs aspect which 62 months the - project works will be in are unable to back down.

  Until this time, the air bureau leads reports jointly to Third Mechanical Industry Department pointed out: “the east wind 113' the plan postpones repeatedly, the most basic reason is designs the index has the very great distance with our country aircraft industry existing technology and the craft production level, thus meets ~ series contradiction inevitably, these contradictions are not in the short-term can solve”. Meanwhile, mimicked the Mig 119 to have the serious problem, left the plant the aircraft quality flaw to be very big, the technical personnel have to strongly solved these problems, “east wind 113” the experimental work in fact stopped gets down. Although later Lin Biao once directly meddled to this computer design many times, exerts pressure lets it continue to carry on, but plans stops from time to time, is still unable to make the substantive progress.

  in April, 1961, Third Mechanical Industry Department acted according to He Long's instruction, clarified the concentrate efforts to do the Mig 119, “east wind 113” trial production suspension. On July 21, the Third Mechanical Industry Department outgoing message pointed out in the same year: “is the reduction front, the concentrate efforts, 119 and the Mig 121 does with the quickest velocity the Mig,' as soon as the `east wind 113 must let allow to pass through suitably, then, in the Mig 121 trial produces in the successful foundation to do " the east wind again 113”. The file and stipulated: “part `east wind 113' the work may continue to carry on”, but in fact this project was also equal to that the announcement discontinued.

East wind 107 and east wind 113 fighter planes [chart] (3)

  “the east wind 113” the design index is the maximum speed 2.5 Mach, the ceiling 25,000 meters, the thrust-weight ratio reaches as high as 0.92, the maximum overload is 8G, does not hang when the auxiliary oil tank range 1,430 kilometers, when 40000 meters heights the mutation angle velocity is 8.34 degrees/seconds, the turn circle radius 1,780 meters - such aircrafts, if could make in 1961, that was really China is arrogant.

  “is familiar with Tang poem 300, but do not do only the Mig theory”

  “east wind 113” around the research and development lasts for 3 years, although also obtains certain single item achievements in scientific research, but creates the loss is bigger. Specially serious is, because the substantial technical personnel centralize do the new computer research and development, relaxed to the Mig 119 importing technology digestion and the mimicking problem solution, created the entire 3 years which started from 1958 not to be able to deliver 1 qualified aircraft, has delayed the prompt update which the air force equipped. At the same time, but also therefore also laid down already the test flight to succeed annihilates teaches a 1 experimental work, has affected the aircraft industry development.

  “east wind 113” the research and development has divorcedded from our country's reality seriously. For example, this kind of Aircraft Design velocity requires to surpass the thermal barrier, but at that time we in regard to the aerodynamic center heat and the thermal reaction problem, theoretically have not solved with the experiment at; Outside the aircraft cockpit cover the temperature is 190 degrees, inside only then do 20 degrees, which one material make with? The ministry of construction once arranged 16 units to carry on the key attack, spends more than one year of time, not yet discovers the direction. As for dynamic system aspect problem, is more complex, before “turbojet” - 6 engine's turbine wheels, temperature only then about 800 degrees, but “the east wind 113” the use “814” the engine reaches as high as 950 degrees, places hopes in researches the brand-new advanced engine in passing in the Aircraft Design process, is very not realistic.

  “since the Great Leap Forward” as well as “Great Cultural Revolution” has researched many aircraft types, cause us to pay the heavy price, creates this all reasons is works does not attend to actual, advances recklessly blindly - comes from has not had a thorough understanding Soviet Union's technology, in a hurry carries on own design, subjectively anxious wants to occupy in the world secludes the main status, surpasses UK to catch up with US rapidly, Soviet Union does not place in continually the eye; On the other hand, the interior manipulates strategically, the blind competition, carries on some “the martial arts contest” without doubt, creates the internal friction in vain, has wasted originally the very scarce scientific research resource.
  Does not experience the wind and rain, how to see the rainbow

  The lesson “113 on we should absorb which from the east wind” is: All work embark from the reality, tread the heart to come to do the research earnestly, in regard to the technical in different opinions, must listen to earnestly. Simultaneously more importantly, must place the appropriate position at times, studies others outstanding thing, can improve itself well.

  After the Great Cultural Revolution ended, because although economic development's reason also discontinued some individual aircraft types, but only then experiences this kind of essential choices, can encounter the China aircraft industry true brand-new time.

Hu  :o ... Thanks a lot for posting as there are a lot of new information !!

... So if this all if this prooves to be real it seems that "our" - esp. the one I proposed JP to draw - was not the DF-107, but actually the DF-104 . :-\ .. ! (but for my opinion this model looks very much like a Crusader with side intakes ???)

Any idea from You guys ??

Thanks, Deino
