Soyuz 7K-OK Spacecraft Hydrogen Peroxide YAW Thruster-Engine on Display

Description

Soyuz 7K-OK spacecraft Descent Module Hydrogen Peroxide Yaw Thruster for attitude control, measuring approximately 11.1/2" x 6.1/2" x 4.1/2", engraved on the central bracket in red,  The nozzle measures 2 inches in diameter and is engraved above. The thruster is set on a metal display mount with a base.  In fine condition. Hight with the stand is 13.1/2” (35 cm), metal base size is 8” x 5.1/2” (20 cm x 14 cm).
The Soyuz Descent Module used eight reaction control micro-jets as part of the Entry Actuators System, with two for pitch, two for yaw, and four for roll; the pitch and yaw thrusters provided about 8 kilogram-force while the roll thrusters provide about 15 kilogram-force. Peroxide is catalyzed in the system, breaking down into water and oxygen that escapes at high speed to create thrust.
