Ivan Bratukhin

Russia

 

1903-1985

Ivan Bratukhin worked on early autogyro and helicopter research under Soviet aviator Boris Yuriev, including the 11-EA PV, an improved version that demonstrated nearly 1 hour of endurance with two crew members. After the War, Bratukhin continued development, resulting in the G-3, G-4, B-5, and B-11 lateral twin helicopters. However, performance was hampered by vibration.
