    摘要: A method for densifying the LO2 propellant of a vehicle (10) includes providing a heat exchanger (16) including a chamber (22), and an isolated heater (24) and cooler (26) located within the chamber (22). The method further includes the step of pumping propellant (LO2) (with pump 14) from the vehicle (10) to the first port (24i) of the path of the heater (24), to thereby create a flow of propellant (LO2) through the heater (24) path, and from the second port (24o) of the path of the heater (24). In conjunction with the pumping, propellant (LO2) is coupled from the second port (24o) of the heater (24) back to the vehicle (10), to thereby establish a recirculating flow of propellant (LO2). The chamber (22) of the heat exchanger (16) is filled with at least sufficient cryogenic liquid (LN2) to cover at least a portion of the path of the cooler (26), and preferably the entirety of the path of the cooler (26). A cryogenic fluid (LH2) is boiled, to thereby cool the cryogenic fluid, and the resulting cooled cryogenic fluid is flowed through the path of the cooler (26). As a result, or whereby, the flow of the cooled cryogenic fluid through the cooler (26) cools the cryogenic liquid, and the cryogenic liquid cools the heater (24) by convection (60). When the cryogenic liquid cools the heater (24), the cryogenic propellant (LO2) flowing through the heater (24) gives up heat to the cryogenic liquid and becomes cooler (26), thereby densifying the cryogenic propellant (LO2).

    摘要: Apparatus for producing liquid or solid xenon comprises a duct 12 having an inlet 14 for receiving gaseous xenon and an outlet 16 for outputting gaseous xenon at a reduced temperature to a nozzle located in a vacuum chamber 60. A housing 18 extends about the duct and contains a halocarbon coolant in thermal contact with the duct, and a second duct 24 in thermal contact with the halocarbon coolant for conveying a flow of liquid nitrogen through the housing 18 to control the temperature of the halocarbon. In view of the difference in the pressure of the xenon gas output from the duct and the pressure in the chamber, the thus-cooled gas is caused to liquefy or solidify in the vicinity of the nozzle.
