Item 885 - Russian Missile Thrust Chamber Catalog 409 (May 2013)

(we are no longer accepting bids on this item)
Minimum Bid: $1,000.00
Sold Price: $13,045.20 (includes buyer's premium)


An unfired Isayev S2.720A bi-propellant regenerative thrust chamber developed for use in the second stage of the Soviet S-75M Surface to Air Missile (SAM) system. This chamber burns a hypergolic mixture of triethlamine/xylidine (fuel) with nitric acid as the oxidizer and is rated at 34 KN static thrust. Chamber was produced by the Isayev Design Bureau. In fine condition.

Alexei Isayev specialized in small-scale, liquid-fuelled rocket engines for Soviet manned and unmanned spacecraft. From 1957 to 1967 his engines powered the rockets carrying the first artificial satellites, the first man in space, and the first unmanned probes to the Moon and Venus. At the same time, in the 1950s, he was working on engines for surface-to-air missiles (SAMs) and air-to-sea missiles. An unusual artifact of the Cold War and a reminder that the space programs were largely an offshoot of military research and development. RR Auction COA.
