Space Shuttle Main Engine (SSME) & Main Propulsion System (MPS)Liquid Hydrogen (LH2) Feed System Pressure Transient Shutdown ModelMSC-25208-1An integrated multi-node fluid thermodynamic model that incorporates both Orbiter hardware characteristicsand SSME characteristics, this technology predicts LH2 system pressures including engine feed line pressureand LH2 manifold pressure.U.S. Government Purpose ReleaseSpacecraft Materials Selector (SMS) Expert SystemMFS-31328-1Applicable to select spacecraft, SMS is a preliminary design tool that estimates environmental exposuresand/or materials performance.U.S. Release OnlySTAN5LEW-13009This computer program computes general two-dimensional turbulent boundary-layer flow using finite differencetechniques. Without requiring any modifications to the program code, STAN 5 can handle a wide rangeof boundary-layer problems. The technology has been used extensively at Stanford University.U.S. Release OnlyTURBAN Turbomachine Design CodeLEW-17454TURBAN analysis is performed at the arithmetic mean diameter. The stage velocity diagrams are either allsimilar (therefore have the same work factor) or are determined from an input stage work split. All stageshave the same stator exit angle. Stage-by-stage tailoring of the velocity diagrams is not allowed.U.S. Release OnlyV072 Rotor Wake/Stator Interaction Noise PredictionLEW-17065The V072 computer code predicts noise from rotor wake/stator interactions. The technology can performcompressor rotor wake prediction only, rotor/stator or fan/FEGV interaction only, fan/core stator interactiononly, and both fan/FEGV and fan/core stator interactions.U.S. Release OnlyWOBBLELEW-17325This technology computes the tone noise associated with propellers and predicts axial and circumferentialdirectivity. The acoustic model is exact and accounts for all unsteady sources.U.S. Release Only5. Propulsion46NASA Technology Transfer Program Software Catalog 2014
