The TsAGI A-4 was an early Russian autogyro, influenced by Cierva designs and delivered in small numbers to the Soviet Air Force in 1934.
Recognition (WEFT)
| W — Wings | Low-mounted, rotary |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 7.22 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Four-blade rotor on a tall three-legged pylon
- Small low wings with ailerons, braced above by parallel struts
- Radial engine in the nose with a Townend ring and two tandem open cockpits
It has a pylon-mounted rotor, a tractor engine, small wings with ailerons and a conventional tail. A lever allows the rotor to be connected to the 220 kW M-26 engine for jump starts.
Specifications
- The TsAGI A-4 has a length of 7.22 m (24 ft).

History
The 1931 design was broadly similar to the Avro-built 1929 Cierva C.19. It first flew on 6 November 1932, but it took about a year to solve rotor vibration problems and complete successful tests.
Variants
At least ten were built in a small series.
Where you'll see it
At least ten A-4s were delivered for military training, liaison and reconnaissance duties during 1934.
