Amphibious cargo gliders were created in the Soviet Union in the early 40-ies. Glider Landing KC-20 20 people design capacity of PV Tsybina and DN Kolesnikova 1942 appeared in the city two years later, in 1944, at Tsybin designed Glider C-25, which had a capacity of 2,5 t, and later Yakovlev Design Bureau issued a cargo glider.
IL-32 - amphibious cargo glider development Ilyushin Design Bureau commissioned by the country's air force, its construction was completed in the year 1948. Based on the dimensions of the cargo compartment and the load capacity index, the IL-32 significantly surpassed domestic gliders that time. Its purpose was to transport airborne (up to 60 people) and large military equipment (weighing up to 7000 kg). Flight airframe weight 16,6 t allowed to tow aircraft machine Tu-4 or IL-18.
According to assembly scheme IL-32 - this monoplane, which has all-metal construction with a high wing. The glider is made of rectangular cross-section of the fuselage. The cargo compartment is unsealed, it has a height of 2,6 m, width and length of the 2,8 11,25 m m. The load compartment floor made of metal. At the beginning and end of the cargo compartment to starboard are doors. The tail and the nose of the fuselage are made in the direction of reclining. In the cockpit equipped with working space for two people.
wing design of the Il-32 - two-spar, the wing area is 159,5 m², elongation - 8, sweep - 3 °. The relative thickness of the wing on the side - 18%, on the wing tips - 10%. The structure consists of simple rotary wing flaps, ailerons and spoilers, which are located in front of the flaps. High aerodynamic wing-quality and efficient mechanization influence on getting good flight and landing characteristics.
The structure was part of a fixed tail stabilizer, which was fixed on the keel using two lower struts. Rudders and height had a metal structure with fabric covering.
Chassis glider does not retract in flight, tricycle. Due to the telescopic main landing IL-32 performed "squat" to the ground, which, together with reclining aft and bow of accelerate and simplify loading and unloading. At this point, the floor of the cargo compartment above the earth rose by only 650 mm. It puts him side ladders, which lowered its course or raised military self-propelled machinery.
IL-32 glider was equipped with the necessary radio communication, air navigation and electrical equipment.
To determine the tactical flight characteristics 1948 was carried out joint tests of the airframe IL-32 and towing IL-12D. At the time of the test take-off weight of the airframe was 8,4 t. After some time spent towing a glider carrying cargo 7 t and having a takeoff weight 16 ie, IL-18 plane.
IL-32 released in a single prototype, in serial production was not launched.
On the basis of IL-32 in OKB Ilyushin considered the option of creating a glider IL-34, which had in the arrangement of two underwing piston engine. Their purpose is to improve the flight characteristics of the airframe.
