Kamov-Skrzhinski KASKR-1 "Krasny Inzhener"

Designation from Kamov and N.K.Skrzhinskii, autogyro Krasnyi Inzhyener (Red Engineeer), based on Cierva C.8 and likewise using Avro 504 (U-1) fuselage, landing gear and most of flight controls. Original rotor (four braced blades), small wings, and other parts. First ground running test 1 Sept 29. Rotor began to spin, but control system ineffective and subjected to major changes. U-1 rudder changed for larger surface; then torque of engine/propeller almost overturned machine, rectified by hanging 8kg weight under right wingtip. Test pilot I.V.Mikheyev (father of present KB chief) unable to fly aircraft because of lack of power. Rebuilt as KaSkr-2.

Kamov-Skrzhinski KASKR-1 "Krasny Inzhener"

This was the first autogyro made in the Soviet Union. Constructed round the fuselage of a U-1, which was a British Avro 504 built under licence, it had one four-bladed rotor and made a few flights at Moscow aerodrome in 1930.

The KASKR-2 was the same aircraft with a different power source: the former 100hp M-2 engine was replaced by a 230hp M-2 engine of the Gnome-Le Rhone Titan type.

The two designs got their KASKR designation from abbreviations of the names of the builders Kamov and Skrjinsky.
