About
Propellant – hydrazine. The unit consists of 2 pressure stabilizers, 6 small-size solenoid valves that supply propellant to the thruster, and two pressure transducers to monitor propellant pressure. Thermal mode of the unit is ensured by 4 heaters (2 main and 2 redundant), a radiator, and a set of MLI. Unit temperature is monitored by means of 4 temperature sensors. Manufacturing lead time is given without taking into account the time needed to procure materials (4 months) and procured parts and components (6 months).
