TsAGI centenary in the history of aviation:TsAGI 1-EA helicopter
15 August 2018
August 14, 1932 is a significant date in domestic aviation history. Eighty-six years ago, Alexey Cheryomukhin, the designer and pilot of the first helicopter TsAGI
The domestic science rotary-wing aircraft school was developed in TsAGI. A Helicopter Group, established within the TsAGI Experimental Aerodynamic Department, was engaged in theoretical and experimental research, as well as designing experienced helicopters and gyroplanes. Scientists carried out rotorary model tests with a screen, simulating ground surface, and also without the screen. All the characteristics were studied at hover mode and oblique flow. The rotors were carefully researched in autorotation mode at vertical descent and gliding flight.
The next step in the development of the helicopter industry was the establishment in 1928 of a ground installation to test major rotors in hover mode. The idea behind its development belonged to A.M. Cheryomukhin. The installation enabled research of aerodynamic characteristics of rotors, including the swashplate. The experiments were conducted in conditions of secrecy, so scientists worked under cover of night, despite the fact that it was winter.

They started to design an experimental model helicopter. The overall design authority was entrusted to Boris Yuriev, a N.E.Zhukovsky team-mate. Alexei Cheryomukhin was appointed to be responsible for design development and strength analysis. He had already had by that time the experience of participation in the construction of the first Soviet aircraft COMTA, development and launching wind tunnels T-1-2, etc.
