Description

Saturn rocket engine prototype designed for Trans-Lunar Injection

Prototype TR204 Saturn V Third Stage Auxiliary Propulsion System Rocket engine, measuring approximately 16″ long with a 6.75″ diameter nozzle, with a George C. Marshall Space Flight Center metal label with both printed and engraved text, reading, “Engine Auxiliary Propulsion Attitude Control 150 LB., Assy No. 700701-2, Mod. No. 700700-2, DAC Spec. 1A39597-1, Contr. No. NAS7-101, Ser. No. 008, Date 7-9-64.” Fabricated by Thompson Ramo Wooldridge (TRW), the nozzle and chamber are made of phenolic impregnated silica with fiberglass overwrap. The nozzle has a sprayed zirconia coating, with the propellant inlets and valves made of metal. Its design is unique—because of the requiremet for high reliability, the engine was designed with quad-redundant valves. In fine condition, with scattered marks and dings. These engines were in service from January 1966 to July 1975 and saw application on every Saturn V Moon rocket to provide attitude control of the Third Stage during Earth Orbit and Trans-Lunar Injection. These engines also provided propulsion after third stage separation from the Command Service Module to propel the Third Stage to impact on the Moon's surface. A magnificent piece of early Apollo history as a necessity for man’s voyage to the moon. This item is export restricted.
