Seems to be based on the I-16 Rata, but my main question is the reason behind it. A
top speed of 245 km/h would have been hardly enough for a fighter of that era and I
can't think, that agility alone would have secured survival. ???

While it superficially resembles the I-16 in general appearance, structurally it has more in common with a Gee-Bee. ;D
The hoped for max speed was to be 333km/h (207mph) at 2,300 m (7,500 ft), with a minimum speed of 39km/h (24 mph) at 1000 m (3,300 ft) and a ceiling of 7,500 m (24,600 ft). The actual performance attained was 246 km/h (153 mph) at 2,200 m (7,200 ft) down to 51 km/h (32 mph at 900 m (3,000 ft). Maximum altitude attained was 5,600 m (18,200 ft). It was felt that a max speed of 300 km/h (186 mph) was attainable. The aircraft crashed on May 23, 1937 when a rotor blade detached due to a fatigue fracture of the blade spar. The pilot, I. Kozyrev, was killed. The aircraft was powered by a Wright Cyclone F-3.

Stingray, the A.14 was a really bird, but only a prototyp. This autogyro was build under Kuznetsov, derived from A-6 and A-8. First flown 1935.
