History

Valentin Petrovich Glushko was appointed chief designer of the newly-founded OKB-456 design bureau on July 3, 1946. The company was quickly tasked with the production of a Russian copy of the German V2 rocket engine, under the supervision of Glushko and 234 German designers added to the company in October, 1946. At the end of that year, OKB-456 took up residence in an aviation factory near the city of Khimki

, just outside Moscow. Here, the bureau constructed facilities to build and test fire its engines. The RD-100 performed admirably, and low-pressure LOX/Ethanol engine development continued, in the form of the RD-102 and RD-103. However, the development of high-pressure engine technology allowed propellants with a higher energy density to be used, and so LOX/Kerosene quickly replaced LOX/Ethanol as the propellant of choice.

Storable Propellants & Hypergols

In 1954, the development and success of the LOX/Kerosene RD-107

 and RD-108 engines allowed the company to expand its engine development work further. The RD-214 engine, using a storable mixture of Nitric Acid

 and Kerosene, was developed for ballistic missiles with a short readiness time requirement. The RD-214 was soon superseded by the RD-216 and later variants, which used a hypergolic combination of UDMH and Nitric Acid. This line of development later led to the highly successful NTO/UDMH RD-253 line, which was the most powerful hypergolic engine of its time, and remains in production to the current day.

High Pressure Engines

The RD-107 and RD-108 engines developed from 1954-1957 were extremely reliable and widely used. However, DB Energomash (renamed from the original OKB designation in 1967) saw great potential in the development of LOX/Kerosene engines with a higher chamber pressure. This presented many challenges to the engine designers, most notably the development of a turbopump

 which could deliver enough propellant to keep the engine running at a pressure high enough to maintain combustion stability. The resulting engine, developed in the early 1980s, was the RD-170, which runs at a chamber pressure of 3500 psi
