A Pump Module for the Space Station Freedom Active Thermal Control System

Space Station Freedom employs a pump module to provide fluid pumping, fluid pressure and temperature regulation, and fluid management in its active thermal control system. The pump module utilizes a multifunction pitot pump for fluid pumping, a servo actuated vapor regulator for fluid pressure and temperature regulation, and an accumulator to aid with fluid management. Pump module component designs are tailored to the specific requirements of the thermal control system. Prior to use on the Space Station, the pump module will undergo a comprehensive test program that includes engineering development tests and flight qualification tests.
