Yakovlev Yak-20
The Yakovlev Yak-20 (in Russian Як-20), was an experimental piston-engined trainer developed in the USSR in 1949. It did not go into production.〔Gunston, 1997〕
==Design and development==
In 1949 the Yak-20 was designed by the OKB for use with aviation clubs as a trainer and sport aircraft. Intended to be the cheapest modern aircraft that could serve as a useful pilot trainer and aerobatic sport aircraft, the Yak-20 was intended to be considerably cheaper to build and operate than the contemporary Yak-18.〔Gunston, 1997〕
Though structurally similar to the Yak-18, the Yak-20 had a welded steel tube fuselage which was skinned with aluminium alloy sheet and fabric, with Aluminium alloy wings, skinned in metal back to the single spar, and fabric aft of the spar. Accommodation was side by side under a large blown canopy, which slid open to the rear. The cockpit had dual stick controls, with the pilot sitting to port. There was a central push-pull throttle, and simple gyro instruments. The engine was the newly developed Ivchenko AI-10 five cylinder radial. This engine was small, and extremely light. It was rated at 80 hp, driving a V-515 controllable-pitch counterweight propeller. Fuel was carried in two 35 liter (7.7 gallon) tanks in the wing roots, ahead of the single spar.〔Gunston, 1997〕
