GEMINI SPACECRAFT ROCKET ENGINESIGNED.
ATTITUDE CONTROL FOR THE GEMINI SPACECRAFT.
SE-6 rocket engine made from steel, other metals, and ablative material at the nozzle end, 10 inches long and 4 inches wide. A black and silver identification tag reads in part: "PART NAME: Thrust Chamber Assy(Assembly), MFD BY ROCKETDYNE FOR MCDONNELL. PART NO. 208130-71, MOD. NO. SE-6, SER 4060122.... MCDONNELL PART NO. SCD52-52700-239." The tag includes two inspection stamps. With a 5½ x 4 inch red Rocketdyne nozzle cover which reads: "RK 395-3001, INSTALL 1/6 UNIT DESICCANT."
A set of eight of these bi-propellant engines were located in the equipment section aft of the crew compartment which was part of the Orbit Attitude and Maneuver System (OAMS). Yaw, pitch, and roll spacecraft torques were obtained by firing these engines in pairs. Sixteen additional SE-6 engines made up the Reentry Control System (RCS) in the nose of the Gemini spacecraft. SE-6 engines produced 25 pounds of thrust. Each engine assembly consisted of a fuel and oxidizer valves with injector systems, a combustion chamber, and expansion nozzle. The fuel value system on this engine was removed for testing.
SIGNED by WALLY SCHIRRA and TOM STAFFORD near the identification tag. Each has added "GT-6." The SE-6 engines on the Gemini 6 spacecraft assisted Schirra and Stafford in performing the world's first rendezvous with Gemini 7 in December 1965.
