Ilyushin Il-24 bomber

The I-22 variant with AM TKRD-01 engines received the designation Il-24. The project of the front-line bomber Il-24, which retained the appearance of its predecessor, but with two more powerful AM TKRD-01 engines, remained unrealized. Almost simultaneously with the development of the Il-22 aircraft, the Ilyushin Design Bureau was tasked with developing another Il-24 bomber with two powerful jet engines of A.A. Mikulin TKRD-1 with a thrust of 3300 kg. During the design process, they were replaced by licensed RD-45 engines with a thrust of 2270 kg each, but with greater reliability. It was expected that these engines could significantly improve the flight data of the IL-24, but its design scheme, almost completely repeating that of the IL-22 (in turn, taken from the German project Heinkel He-343), was also unacceptably heavy.

The MAP expert commission first approved this proposal in May 1947, but a year later its prototype was discontinued. Too heavy was a machine that was not adapted for operation from unpaved airfields. The massive construction of artificial runways at the existing airfields at that time, the country could not afford.

This was the reason for the cessation of work on this machine. A reconnaissance version of the aircraft was also developed. It was supposed to install four cameras for planned and perspective shooting, as defensive weapons there was one front and two rear guns. After re-equipment, the IL-24 was supposed to have a maximum speed of 900 km / h, a range of 3,000 km and a practical ceiling of 13,000 m.

In 1947, on the instructions of I.V. Stalin MAP has developed a proposal to create and launch into serial production of new reconnaissance aircraft. At the same time, it was supposed to convert some of the bombers, built according to the pilot construction plan for 1947-1948, into reconnaissance. Along with the aircraft of other design bureaus, this proposal also touched on two projected bombers S.V. Ilyushin - IL-22 and IL-24. On the first of these, it was proposed to install 4 cameras for planned and prospective photography, replace the TR-1 engines with licensed Dervent-V, and reduce defensive armament to one front gun and two cannons for firing back. After the conversion, the aircraft was supposed to have a speed of 800 km / h, a range of 3250 km and a practical ceiling of 12,500 m. The conversion of the IL-24 concerned replacing the AM-TKRD-01 engines with NIN-1 licensed engines. After the conversion, the Il-24 aircraft had to have a maximum speed of 900 km / h, a range of 3,000 km and a practical ceiling of 13,000 m. Changes to the photo equipment and defensive weapons were identical to those on the Il-22.

The work on the creation of the Il-28 S.V.Ilyushin began after the completion of the work on the Il-22 / Il-24 on an initiative basis at a time when the design bomber A.N.Tupolev was building a front-line bomber (later called the Tu-14), according to the official Air Force mission. A comparative analysis of various options for the defensive weapons of bombers showed that using only a stern cannon mount in combination with the appropriate maneuver of the aircraft, it is possible to effectively repel the attacks of modern fighters from the rear hemisphere and provide reliable protection for the machine. The creation of the first in the USSR two-gun electro-hydraulic fodder plant Il-K6 and determined the basic layout features of the Il-28.

In January 1948, work was completed on a preliminary design of the IL-28 aircraft, the calculated flight and technical characteristics of which significantly exceeded the values obtained on bombers previously created at the Design Bureau. The design of the aircraft embodied all technological solutions that worked well during the construction and testing of the IL-22. However, the outline design aimed at approval at the Air Force Research Institute did not find support from the Customer.
