Abstract:

The use of liquid O2 in space vehicles depends upon utilizing a converter that can maintain control of operating pressure and delivery rate under varying gravitational fields including zero gravity. A new converter was designed with an automatically controlled mechanical heat valve for controlling the internal pressure of the flask. The design includes an internal control valve and heat transfer coil to prevent excessive boil off during standby conditions. A prototype zero gravity flask incorporating these features was built and tested. Performance tests showed the he t valve would be effective for controlling heat flow to the flask under various attitudes and gravitational forces. The internal valves leaked across the seat preventing complete shut off. The tests showed the design concepts to be a promising approach for controlling liquid O2 under zero gravity conditions.
