RD-58
From Wikipedia, the free encyclopedia
RD-58 (manufacturer designation is 11D58) is a rocket engine, developed in the 1960s by the OKB-1, now RKK Energia. The engine was initially created to power Block D stage for N-1 Moon rocket. Now derivatives of Block D are used as upper stages on some Proton and Zenit rockets. Another version of RD-58 chamber, with shorter nozzle, was used as the roll control engine on the N-1. The Buran spacecraft had 2 descendants of RD-58 as its main engines.
RD-58 uses LOX as the oxidizer and kerosene as the fuel. It features a single gimbaled chamber, radial centrifugal pumps with auxiliary booster pumps, and an oxygen-rich gas generator. Recent modifications had a lightweight carbon composite nozzle extender.
