Ilyushin Il-18 (1946)
The Il-18 was developed to meet Aeroflot's need for a high-altitude, long-range aircraft to fly its long-haul national and international routes.It was conceived as a cantilever low-wing monoplane, powered by four Charomskii ACh-32 diesel engines, as initially used in the Ilyushin Il-12, with a tricycle landing gear.The pressurized fuselage was circular in cross-section, which provided room for cargo and baggage compartments under the cabin floor.Electro-thermal deicing boots were fitted on the leading edges of the wings, horizontal and vertical tail, driven by four engine-driven electric generators.However, this proved to be in vain because the manufacturer's flight tests were not concluded until 30 July 1947 as the turbo-superchargers were not delivered in a timely manner.
