Chemical Equilibrium Applications (CEA)LEW-17687The CEA program calculates chemical equilibrium product concentrations from any set of reactants anddetermines thermodynamic and transport properties for the product mixture. Built-in applications accountfor theoretical rocket performance, Chapman-Jouguet detonation parameters, shock-tube parameters, andcombustion properties.U.S. Release OnlyCMPSTK Multi-Stage Axial-Flow Compressor Off-DesignLEW-17451Developed for studying variable geometry effects at the conceptual design level, CMPSTK is a combinationof the STGSTK and CMPGEN computer codes. STGSTK predicts multistage axial-flow compressoroff-design performance using mean-line stage stacking, and CMPGEN estimates design-speed flowrange and efficiency ratios.U.S. Release OnlyCommercial Modular Aero-Propulsion System Simulation (C-MAPSS)LEW-18315Note: Software Restricted by Export ControlWritten in a combination of MATLAB and Simulink, C-MAPSS provides a realistic simulation of a largecommercial turbofan engine. The technology includes a number of graphical user-interface screens thatallow point-and-click operation.U.S. Release OnlyCommercial Modular Aero-Propulsion System Simulation (C-MAPSS), Version 2LEW-18315Note: Software Restricted by Export ControlVersion 2 of C-MAPSS provides a transient simulation of a large commercial turbofan engine with a realisticengine control system. Written in a combination of MATLAB and Simulink, the software supports easyaccess to health, control, and engine parameters through a graphical user interface. Retaining the convenienceand user-friendliness of the original, Version 2 includes three actuators (as compared to one) andoffers an improved controller as well as added actuator and sensor dynamics.U.S. Release OnlyCommercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k)LEW-18624-1Note: Software Restricted by Export ControlDeveloped in the MATLAB/Simulink environment, C-MAPSS40k is a high-fidelity transient simulation ofa generic commercial turbofan engine with a 40,000-pound thrust. The nonlinear physics-based component-levelmodel operates up to Mach 0.8 over a wide ambient temperature range and executes faster thanreal time. The model can be run from the command line or by using a graphical user interface.Compressible Flow ToolboxLEW-17898The Compressible Flow Toolbox is a set of algorithms that solve classical compressible equations for isentropicflow, fanno flow, Rayleigh flow, normal shock, oblique shock, and expansion. Implemented in theMATLAB programming language, the technology can be used in the analysis of one-dimensional steadyflow with constant entropy, with friction, with heat transfer, or with supersonic Mach numbers.U.S. Release OnlyComputational Fluid Dynamics (CFD) Seal Analysis CodeThis technology is a computer program designed for the study of fluid dynamic forces.U.S. Release OnlyLEW-165825.
