Boris Yuryev

(1889 – 1957)
Boris Yuryev

Soviet aviator and scholar, member of the USSR Academy of Sciences, invented the swash plate for helicopters.

Boris Yuryev was born in November in 1889 in Smolensk.

Boris Yuryev studied at the Moscow Technical School, under Nikolay Zhukovsky’s aviation and flight circle. In 1911 he led flight preparations for a plane that was built by Zhukovsky’s students. At that time Yuryev patented a helicopter that used a system he developed, and which went on to become the classic system for single-rotor helicopters with a swash plate, rotor and anti-torque (tail rotor).

Yuryev was taken prisoner during the First World War, in summer 1915. After returning to his studies in 1918, Yuryev defended his design, and later started teaching at the Military Aviation Academy.

In late 1919, Boris Yuryev started working at the Central Aerohydrodynamic Institute (TsAGI). During experimental work, Yuryev put forward the concept of cyclic pitch for rotor control, proposing a method for calculating the impact of friction on the rotor and rotation rate. It was Yuryev who developed the relative vortex theory.

In 1926, a working group was formed to develop a helicopter on the basis of the design proposed by Yuryev. The result was the TsAGI 1-EA helicopter, which pilot Alexey Cheremukhin set a height record in.

In the 1930s, Boris Yuryev took part in setting up the Moscow Aviation Institute.

In 1941 Yuryev worked on developing the two-rotor Omega helicopter. And in the 1940s he also held the position of deputy head of the Zhukovsky Military Aviation Engineering Academy.

In 1956 Yuryev joined the USSR’s national committee on theoretical and applied mechanics as an inaugural member.
