Hi! "74"?

http://aviadejavu.ru/Site/Arts/Art5528.htm

Wikipedia says that...
Tu-73: three-engined development of the Tu-18, 1947
Tu-74 (also known as Tu-73R): proposed high-altitude reconnaissance aircraft developed from the Tu-73

And
https://books.google.co.jp/books?id=fOC7Ii5SgZUC&pg=PA102&lpg=PA102&dq=Tupolev+Tu-74&source=bl&ots=Eyz9r3JP4_&sig=mC1zUv8WE-eqm7uTVKN65KmHC00&hl=ja&sa=X&ved=0ahUKEwiJ-ODMnbfRAhXGiLwKHXlJBWwQ6AEITzAK#v=onepage&q=Tupolev%20Tu-74&f=false

So I can count five........

In page 111 of Yefim Gordon's amazing book "OKB TUPOLEV, A History of the Design Bureau and its Aircraft", I found almost same drawing compared with this drawing , which is named "76 mixed power bomber". This aircraft looks like "74".

Projects ?.

They are;

Tu-74/I     was a high altitude recce Project of 1946,powered by two M-93 engines
Tu-74/II    was a high altitude bomber Project (maybe in 1946),also powered by two M-93s
Tu-74/III   was a high altitude recce Project of 1947,powered by two ASh-84TK engines
Tu-74/IV   was a high altitude recce aircraft,work stopped in 1948,powered by two ASh-84TK +
                  one Nene RD-45 engines
Tu-74/V     was a high altitude bomber Project of 1947,fitted with swept horizontal tail of Tu-73,
                  powered by two ASh-84TK + one Nene RD-45 engines

Hi,

also the Tupolev Tu-76 was appeared in three concepts;

Tu-76/I     was a torpedo bomber Project of 1946,based on Tu-74 which itself a derivative of Tu-2,
                 powered by two ASh-73TK + one Nene RD-45 engines
Tu-76/II    was a medium bomber Project of 1947,powered by two M-3 engines
Tu-76/III   was a troop transport aircraft,also known as Tu-4D,powered by four ASh-73TK
                 engines

Hi,

also the Tu-73 was allocated to five variants;

Tu-73/I    was a short-rang bomber Project of 1946,drawing only,powered by two Nene engines
Tu-73/II   was a medium bomber aircraft of 1947,powered by two Nene + one Derwent V engines
Tu-73/III  was a front-line bomber aircraft of 1948,powered by two RD-45 + one RD-500 engines
Tu-73/IV  was a long-range bomber Project of 1948,powered by two RD-1 engines
Tu-73/V   was a long-range bomber Project of 1949,powered by two RD-2 engines

Hi! Tu-78.
http://aviadejavu.ru/Site/Crafts/Craft27588.htm

"Experienced bomber "78" A.n. Tupolev design, equipped with a combined powerplant of two Rolls-Royce Nene engines (in Underwing nacelles) and one(?) Rolls-Royce Derwent Mk V, which was situated in the rear part of the fuselage."

Hi! 489 model and 3-side view.
http://www.ussr-airspace.com/index.php?main_page=product_info&cPath=28_39_38_100&products_id=2520

https://ww2aircraft.net/forum/threads/soviet-aircraft-manufacturers.11592/

"a redesigned 6 engined derivative of the Tu-85 that dates from 1948 (there was an 8 engine version proposed as well) designed as 'Project 489'"

"This design then evolved into this one(bottom drawing), still under the same number, it now has more highly swept wing and a fully glazed nose, but the tail is lower than on the Western created picture in my earlier post. "

"There were even some sketchy specs with the drawings, range was 'up to 12,430 miles' Span 183ft, MTOW 209,000lbs and powerplants were to be 6 x Shvetsov ASh-73TK(?) turboprops. "

I wonder what engine 489 had. Single propeller turboprop engine?TVD VK-2?

"In the study were variants of machines "489" with various promising engines: TVD VK-2, diesel engines m-224, as well as combination piston m-222 with a TURBOJET ENGINE Rd-45."

Model large pictures.

http://militaryrussia.ru/blog/topic-765.html

This site says that this model is "485", but engine is turboprop.

Hi! "Deck-mounted torpedo 509. OKB Tupolev. 1950".
http://alternathistory.com/palubnyi-torpedonosets-509-okb-tupoleva-1950g

"In the USSR the question of deck aircraft took quite distinct forms in the late forties, when it adopted an ambitious programme to establish Ocean fleet. It provided for the construction of aircraft carriers and various classes. At the same time aviation KB got jobs on design of deck aircraft. Fighters engaged in collective A.s. Yakovlev, bombers and ground attack aircraft-A.n. Tupolev.
In 1950 year A.n. Tupolev OKB received an assignment to investigate the possibility of creating a deck torpedo bomber with two engines VC-1 with the following data:
-maximum take-off weight-15 t;-maximum speed at an altitude of 5000 m-900 km/h;-ceiling-12000 m;-range with 1500 kg of bombs-1500 km;
-takeoff with 2 accelerators for an aircraft carrier in 20 nodes-220 m;-envelope with folded wing scale-8 m;-aircraft length-15 m;-height-6 m;
-gun armament:forward 2 guns;back to the KDU-2 guns;-caliber guns-23 mm;
-the crew-2 pers.
Conceptual design and production of drawings were completed by 1953 g.
Draft deck torpedo-bomber "509 (9th draft 1950 г.) was created on the base of 81 aircraft (NAVY torpedo bomber TU-14) with a reduction in all options over about a third ... The desire to use this machine as a prototype, it was understandable and natural. Its layout and the technical solutions adopted, as demonstrated by flight tests (1947-49), were acquitted. The powerplant was supposed to be two VK-1 TURBOJET ENGINE with a centrifugal compressor. The main difference were folding wing and brake for planting with ajerofinisherom GAK.
Study showed that the job has the ability to meet the defined dimensions and provide the required information when the takeoff weight 13-15 tons and wing surface 50-60 sq.m. For further calculations you selected with takeoff weight 14.8 tons and wing area 54 sq.m. Certain difficulties were associated with the size of the KDU and sighting radar PRS-1 "Argon".
All performance data was feasible except for the length of the take-off decks at 220 m, which could only be achieved using 4-x.
"509" Project was brought to the stage technical proposal with two variants of the nose of the fuselage (from 81 aircraft or aircraft 82 "), with a wingspan 18.2 m, wing area of 55 sq m, extension wing-6, takeoff weight 15 t and bomb load of up to 3000 kg."

Hi,

there was three Tu-78 concepts;

Tu-78/I    was a twin engined recce airplane Project,based on Tu-8,powered by two ASh-82FN
                 engines
Tu-78/II   was a three engined experimental bomber,powered by two Nene + one Derwent V
                 engines
Tu-78/III  was a bomber Project,powered by three VK-1 engines.
