About
Propellant – hydrazine. The main thruster component parts are: a decomposition chamber with a catalyst element and a nozzle, a propellant injection unit, two small-size solenoid valves that supply propellant to the thruster, and a pressure signaling indicator that monitors the fact that the thruster has been started up. A resistive heater and MLI installed on the thruster chamber ensure the required thermal mode of the thruster. Thruster temperature is monitored by means of two thermocouples. The thruster also has a mounting plate that joins the thruster elements. Manufacturing lead time is given without taking into account the time needed to procure materials (4 months) and procured parts and components (6 months).
