About
The Cool Gas Thruster is engineered for the precise orientation of spacecraft, responding to control system triggering commands by forming multiple impulses. It is specifically purposed for KOSMOS and RESURS-DK spacecraft and boasts flight qualification with a “Letter O” for flight use. The product is designed with small size and mass as key features. It operates using helium or nitrogen as the working medium and offers adaptability to customer requirements. The thruster has a nominal thrust of 0.733 N with helium and 0.819 N with nitrogen, and a nominal specific impulse (steady state) of 1657.9 m/s for helium and 716.1 m/s for nitrogen. It operates with a nominal inlet pressure of 1.765 MPa and an inlet operating pressure range of 1.47 to 1.96 MPa. The total firing time can be up to 10,000 seconds, and it has a cycle life of up to 80,000 start-ups. The nozzle expansion ratio is 64, and it operates at 27 V.
