DESIGN OF H2-C2 SPACE SHUTTLE APU (VOLUME 1 - APU DESIGN)

摘要

The H2-02 Space Shuttle auxiliary power unit (APU) program is a NASA-Lewis effort allowed at hardware demonstration of the technology required for potential use on the Space Shuttle. It has been shown that a hydrogen-oxygen power unit (APU) system Is an attractive alternate to the Space Shuttle baseline hydrazine APU system for minimum weight. It has the capability for meeting many of the heat sink requirements for the Space Shuttle vehicle, thereby reducing the amount of expandable evaporants required for cooling In the baseline APU. Volume I of this report covers preliminary design and analysis of the current reference system and detail design of the test version of this reference system. Combustor test results are also included. Volume II contains (1) the results of the analysis of an Initial version of the reference system In Appendix A and (2) the computer printouts of system performance in Appendix B.
