Hi! Il-22 and Il-24.





"The IL-24 front bomber project remained unimplemented, with the predecessor's image, but with two more powerful UM TKRD-01 engines. The EI Expert Commission first approved the proposal in May 1947, but after a year the prototype was abandoned. A machine that is not equipped to operate from the ground airfields has been overburdened. Mass construction of runways with existing airfields at the time, the country could not afford.

At the same time, the option with four more promising English turbojet "Ning" was also considered. But he was still on paper."

Top to bottom....
Front bomber, Training version and Naval version.
And front bomber sharp three side view.
Actual wing root shape and cockpit shape are little different from model wing root shape and cockpit shape.
And this three side view drawing has no outer wing fence.



This site says that crew are three. But I can see small window behind the pilot. What is this?
"The crew of the aircraft - three people: a pilot, navigator and stern-shooter-radio operator, housed in two (front and rear) hermetic cabs. The pilot and the navigator entered the plane through a small door on the right side of the fuselage, and the shooter through the lower hatch of his cockpit. Between the cabs of the navigator and the pilot there was a passage allowing them to communicate with each other in flight. All crew members jobs had a strong armor protection. If there is an emergency in the flight, the MPA crew leaves the plane with the help of ejection seats, while the pilot catches up, and the navigator and the shooter - down. In case of an emergency landing on the water, all crew members could leave the plane through the upper hatches of their cabins and use the automatically disengaged rescue boat LAS-5M.

The defensive armament of the aircraft consisted of three guns, which had a high rate of fire and the power of a second volley. The front hemisphere was protected by a stationary gun, mounted on the left side of the fuselage. Two mobile cannons were installed in the stern of a remotely controlled turret, the combat qualities of which were significantly improved in comparison with the previously used defensive installations. The weight of the maximum bomb load of the IL-54 aircraft is 5000 kg."

Hi!
Also increase span? Wing sweep back angle decrease? Pilot cockpit height increase? Flap shape is different? Ventral radar size is different?
Fuselage cross section shape is different?

Terribly sorry. Perhaps I made a big mistake.
I think that this drawing is not reliable.
Engine interval is too large compared with actual Il-54 front view picture.
Engine interval/engine nacelle outer diameter=7.5, I think this value is 6.17.
Fuselage cross section is not circular nevertheless pressurized cabin.

I believe that this is a correct Il-54 three side view drawing.
Cockpit is small compared with actual Il-54 side view picture. Because this drawing shows No.2 prototype.
Wing sweep back angle is around 58°. Little large?
Horizontal and vertical tail stabilizer shape are good compared with actual side view picture.
(Please check page 153 of "OKB ILYUSHIN" if you have. You can see very rare IL-54 No.2 prototype picture with different cockpit shape compared with No.1 prototype and no outboard wing fence.)
I want to see Il-54 No.1 prototype three side view drawing.

Perhaps this side view shows IL-54 No.1 prototype.
I imagine that IL-54 No.1 prototype wing sweep back angle is 55°. No.2 prototype wing sweep back angle is 58° and no outboard wing fence.
Perhaps ventral fin was added after flight test.

Hi! I believe that these drawings nearly shows IL-54 No.1 prototype(wing tip wheel retractable direction is old, and overall length is little short?) and No.2 prototype or unbuilt final plan.(Almost same scale)
Perhaps No.2 prototype or unbuilt final plan wing span is smaller than No.1 prototype wing span.


I believe that there is a rare IL-54 second prototype flying picture in Jane's all the world's aircraft in 1956-1957 or 1958-1959.
Someone has this volume? Perhaps copyright is over.

Hi, guys!
One of the very early Il-12 double-tailed project with ACh-31 engines. Note the shape of the fuselage nose part - it was used than in Il-18 (1947)

in my files;

the early Il-12 Project had a four engines,does any one hear or got a drawing to this
design ?.

Hi,

also the early design Project of Il-18 was a four engined aircraft in 1945.

That was the Il-30 which was completed but never flown owing to concerns over the structural strength of the wings.

For this thread,

we can't divide it into pieces,because it has many subjects,most of them only one post
or two.

In my files,

there was two version of Il-98,and not one,maybe had different shapes.

So I have two Il-38 drawings. Landing gear shape is different.
Explanation of top drawing is as follows. http://alternathistory.com/proekty-frontovykh-bombardirovshchikov-il-38-i-il-42-sssr
"At the insistence of SV Ilyushin, IL-38 was carried out in triple. Defensive weapons were the same as Il-28: two HP-23 guns protected the front hemisphere, and the Il-K6 feeder with two HP-23 covered the rear hemisphere. The main support of the chassis was four - under each of the nacelles there were two supports. They had one wheel each and retracted one forward, the other back. At the same time, the wheels were rotated 90 ° and laid flat into the lower part of the nacelle.
The bomber project received a positive evaluation from the customer, who, however, deemed it necessary to improve the aircraft's take-off data by installing more powerful engines."


I think that the second drawing is incorrect.

- Tony Buttler & Yefim Gordon, Soviet Secret Projects Bombers Since 1945 (Midland Publishing, 2004), pp. #30-31

The Il-30 had a sequel shape of a project designated Il-38, which was a twin engined bomber powered by two TR-3 engines. It retained the Il-30's basic shape and carried the same bomb load but different from its predecessor in having smaller dimensions, a lower weight and a revised defensive armament borrowed from the Il-28 (comprising two forward-firing NR-23 cannon supplemented by the Il-K6 tail turret with two NR-23 cannon). There were three crew and the bicycle undercarriage gave way to a tricycle arrangement which differed from the Il-28, being more along the lines of that used on the Il-46 except that the twin wheels on each main leg were moved further apart to either side of the nacelle; this arrangement resulted in the characteristic low sit of the aircraft on the ground.
The project drew favorable comment from the Air Force but the military wished to see an improved airfield performance through the use of more powerful engines.
