Bratukhin
Bratukhin, or OKB-3, was a Soviet aircraft design bureau created in 1940 from within TsAGI to develop helicopters. Headed by Ivan Pavlovich Bratukhin, the bureau built several experimental helicopters over the next decade. Each model had the same basic design of two rotors with separate engines carried on the ends of outriggers to each side of the fuselage.2 It is part of Moscow Aviation Institute.1 Wikipedia text CC BY-SA 4.0
