Who was Aleksei Mihailovich Isaev?

Aleksei Mikhailovich Isaev was a Russian rocket engineer.

Aleksei Isaev began work under Leonid Dushkin during World War II, on an experimental rocket-powered interceptor plane, the BI-1. In 1944 he formed his own design bureau to engineer liquid-propellant engines. After abandoning the heavy, complex and undercooled German engine designs, Russia's principal engine designer Valentin Glushko turned to Isaev's innovations: thin-walled copper combustion chambers backed by steel support, anti-oscillation baffle to prevent chugging, and the flat injector plate with mixing-swirling injectors. The latter was an enormous simplification of the "plumbing nightmare" of the V-2 engine, because it avoided the need for separate fuel lines to each sprayer.

Although his inventions influenced the design of Glushko's large engines, Isaev was better known for building efficient small rockets. He designed engines for the Soviet anti-missile and anti-aircraft rockets, and in 1951, his engine powered the R-11 Zemlya short-range missile, later named the Scud.
