Soyuz Descent Module Hydrogen Peroxide Yaw Thruster for attitude control, measuring approximately 11.5 x 6.5 x 4.5, engraved on the central bracket in red, “11 615 87-50-0 N2250.” The nozzle measures 2″ in diameter and is engraved above “N358.” The thruster is set on a metal display mount with a base of 13 x 7, standing about 13.5″ tall. In fine condition. 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.
