Sergey Izotov

Sergei Petrovich Izotov (1917-1983) was a Russian chief designer of engines who served as Chief Designer and General Designer of the design bureau OKB-117 from 1960 to 1983. He was predominantly an aircraft turbine-engine designer, but his bureau also developed the engines for Vladimir Chelomey's UR-100 missile and for the LK-700 manned lunar lander proposed by Chelomey's team. The Encyclopedia Astronautica lists an Izotov bureau as a Russian manufacturer of jet and rocket engines and gives his birth date of 30 June 1917 and his death date of 6 May 1983. The page is brief, so this entry records his role, the two space and missile applications it names, and his dates, and it makes no claim about engine performance or flight use.
