TSh-2, TsKB-21 by D.P.Grigorovich
Development of the TSh-1 armored attack aircraft with several:
- machineguns were installed in the slightly thicker wing instead of underwing nacells;
- rear gunner got DA-2 turret with paired machineguns;
- wing frame was duralumin, cover - fabric;
- cooling system was tuned to perfection;
Two prototypes entered trials in late 1931, powered by imported BMW-VI engines. Flight performance was good, and series production was ordered with domestic M-17 engine. New engine brought back old problems with cooling...
First ten TSh-2 were finished in 1932, and production was cancelled in favor of more promising monoplane TSh-3 (TsKB-4) which was already under development.
In 1932 one of TSh-2 was re-engined with experimental W-engine (three raws of cylinders) engine M-27. Test flights by Yu.I.Piontkovskij revealed no advantages.
