About Leonid Dushkin
- Leonid Stepanovich Dushkin (?????? ?????????? ??????) (August 15, 1910 in the Spirove settlement of the Tver region – April 4, 1990), was a major pioneer of Soviet rocket engine technology.
- He graduated from Moscow State University with a degree in mathematics and mechanics.
- In October 1932, he joined Fridrikh Tsander's brigade of GIRD, the Moscow rocket research group.
- He assisted in the creation of their first rocket engine OR-2, and after Tsander's death, he oversaw the creation of engine "10" which powered the first Soviet liquid-fuel rocket, GIRD-X. Dushkin's engines were among the first to be regeneratively cooled, and he also experimented with uncooled engines of high-temperature ceramic.
- The 12K engines were of both types, and powered the Aviavnito rocket. After the arrest of Valentin Glushko, Dushkin took over the development of rocket engines for the rocket-enhanced fighter plane RP-318.
- He became the leader of the department of liquid propellent rocket engines in NII-3 beginning in January 1938.
- Starting with Glushko's engines (ORM-65 and RD-1), he began a series of important engineering transformations, moving the fuel injectors to a head at one end of a cylindrical chamber, typical of modern design.
- The RDA-150, RDA-300 used nitric acid as an oxidizer, RDK-150 used liquid oxygen. The 1100 kgf thrust engine, D-1-A-1100 was developed for the rocket-powered interceptor BI-1.
- It was also regeneratively cooled, using the kerosine to cool the chamber, and the nitric acid to cool the nozzle.
- Starting with that engine, Aleksei Mihailovich Isaev began the evolution of his engines, which continued the evolution of engines toward the space-rocket engines of the 1950s.
