Yakovlev Yak-24

The Yak-24 saw limited use in the Soviet Air Force, and the exact number produced and duration of service are unknown due to inconsistencies in data.

It was powered with two 1,268 kW (1,700 hp) Shvetsov ASh-82V radial engines and was built in a tandem rotor layout, which was not typical for Soviet helicopters, which soon brought it the nickname Letayushchiy Vagon (Russian: Летающий вагон) – 'the Flying Railroad Car'.

After the problems were partially solved, the new helicopter was ordered for production by the Soviet Air Force, which began in 1955 at Factory No.

[9] There were two proposed models: the Yak-24K nine-seat VIP salon with a shorter fuselage and the civilian Yak-24P for 39 passengers with more powerful 2,013 kW (2,700 hp) turboshaft engines, but neither reached production.

The helicopter was little known, so specifications and technical details varied among different sources, and also older publications claimed, that Yak-24U and passenger Yak-24A were produced.

[10] All sources agree that production of the Yak-24 was curtailed due to technical problems, and the need for a heavy transport helicopter was fulfilled by the successful Mil Mi-6.
