Il-60 military transport aircraft

The problem of transporting mail and cargo, as well as their escorts, arose in aviation almost simultaneously with the appearance of the first aircraft. This problem was also solved on the planes created in the OKB SV. Ilyushin. Having experience in the creation and operation of Il-12T and Il-14T transport aircraft, as well as Il-32 and IL-34 cargo gliders.

The highly qualified design team of like-minded people and its leader, General Designer S.V. Ilyushin, managed not only to successfully solve the problems associated with the production of serial aircraft "IL", arising in aviation plants, but also to conduct numerous preliminary investigations in the field of creating new promising and more sophisticated machines. So on 26 February 1960, the General Designer sent a letter to the State Committee for Aviation Equipment with a request to review the design of the Il-60 military transport aircraft, developed in the Design Bureau, with four turboprop engines with a capacity of 9500 e. In a brief explanatory note he wrote: "The aircraft is intended for transportation and parachute landing of heavy military equipment, industrial cargo and soldiers with weapons".

A sanitary [ie, MEDEVAC] version of the aircraft was envisaged. The flight weight of the aircraft was 129.2 tons. The cargo compartment has a square section of 4m x 4m and a length of 30m and provides cargo transportation of 40 tons (it is allowed to transport goods weighing up to 50 tons due to a reduction in fuel reserves) or 400 soldiers with the necessary equipment or 280 wounded people on stretchers. Parachute landing of cargoes weighing up to 15 tons was ensured.

The aircraft provides continuation of take-off with three operating engines, and the use of large-diameter propellers and special flaps allows, with a take-off weight of 129.2 tons, to obtain a take-off run along the ground not more than 1000 m (with the strength of the soil 7 kg / cm 2 ) and the length of run over the concrete - 750 m, with a landing weight of 109.2 g. Wings of the wing and tail of the aircraft were supposed to be equipped with a thermal anti-icing system. The complex of flight navigation and navigation equipment intended for installation on the aircraft was supposed to provide a flight at any time of the day under any meteorological conditions. It was possible to perform an automatic approach approach to a height of 50 m and a vision of runways and aerodrome structures using the millimeter-channel radar of the navigation system.

But according to the results of the competition, which was announced in the State Committee, the OKB OK Antonova with its wide-body military transport aircraft An-22 was given preference. Still, OKB Ilyushin continued work in the creation of a new military transport aircraft.

The OKB team started the development of the IL-76 turbojet in accordance with the order of the Minister of Aviation Industry of the USSR of June 28, 1966, which ordered research to determine the feasibility of creating a medium military transport aircraft with four turbofan engines, assigned to the military transport aviation of the central subordination and to the front-line WTA for landing and parachute landing of troops, military equipment and military cargoes.
