AIR-2, Ya-2, A.S.Yakovlev

D
evelopment of the AIR-1 with radial engine. It was built in two versions with size and construction almost identical to the predecessor.
The first one was powered by M-23 engine. It had plexiglas canopy covering both cockpits and opening sidewards. But the aircraft was too slow to show advantage of a canopy. In addition engine vibration was above acceptable level.
Second version with 60hp 'Walter' engine had performance slightly worser (due to engine drag) than the AIR-1. Four were built and used for training.
