Investigation of the Unique Cryogenic Pumping System of the CHAFF-IV spacecraft-Thruster Interaction Facility.

摘要

Chamber -IV of the Collaborative High Altitude Flow Facility was designed to obtain high fidelity spacecraft- thruster interaction data. CHAFF-IV uses a total chamber pumping concept by lining the entire chamber with an array of cryogenically cooled, radial fins. Details of Monte Carlo numerical simulation and experimental investigation of the radial fin target array pumping efficiency are presented.
