Propellant Management Assembly (PMA)
Glavkosmos
PMA is intended for propellant supply to stationary plasma thrusters. It provides an outlet flow rate of not less than 35 mg/s. Propellant - xenon. Manufacturing lead time is given without taking into account the time needed to procure materials (4 months) and procured parts and components (6 months
