Abstract:

An advanced LOXLH2 expander cycle rocket engine, producing 15,000 Ibf thrust for Orbital Transfer Vehicle missions, was tested to determine ignition, transition, and main stage characteristics. Detail design and fabrication of the pumped-fed RS44 integrated component evaluator ICE was accomplished using company discretionary resources and was tested under this contracted effort. Successful demonstrations were completed to about the 50 fuel turbopump power level 87,000 RPM, but during this last test, a high pressure fuel turbopump HPFTP bearing failed curtailing the test program. No other hardware were affected by the HPFTP premature shutdown. The ICE operations matched well with the predicted start transient simulations. The tests demonstrated the feasibility of high performance advanced expander cycle engine. All engine components operated nominally, expect for the HPFTP, during the engine hot-fire tests. A failure investigation was completed using company discretionary resources.
