Yakovlev UT-3
Encyclopedia
The Yakovlev UT-3, initially known as the AIR-17 and then Ya-17, was a twin-engine low-wing monoplane aircraft designed by Alexander Sergeyevich Yakovlev
for the Soviet Air Force
(VVS).
The UT-3 was to serve as a training aircraft for pilots of multi-engine aircraft and for training air gunners, bomb aimers, navigators and radio operators. The airframe was constructed largely of wood and fabric-covered mild steel tubing. The prototype was powered by imported French Renault Bengali 220 bhp 6-cylinder inline engines but production aircraft may have used the Soviet-build MV-6 Renault copy.
Testing was undertaken in 1938 and the aircraft was approved for construction as the UT-3. While the prototype had been fitted with armament—2 7.62 mm ShKAS machine guns and racks for 4 FAB50 bombs—the production model was unarmed and more austere. Production was ordered in 1940 at two factories, No. 135 in Leningrad
and No. 272 in Kazan
. Only around thirty aircraft were built before orders were cancelled as the VVS high command decided to used multi-engine combat aircraft, modified for dual control, in place of dedicated training types.
A derivative, the Ya-19, was developed as a four-seat light transport by Oleg Antonov
. In 1940 Aeroflot
requested that the Ya-19 should be produced for use on shorthaul routes, but the increasing pace of rearmament in the Soviet Union meant that only a single prototype was ever built.
