Project TitleCommercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k)
Track CodeLEW-18624-1

This Software is Export-Controlled restricted and will only be released to United States Citizens. C-MAPSS40k v2.x, released 2014. It contains several important new features that add to the realism and usefulness of the package. These include a stall margin calculation that accounts for variations due to off-schedule actuator operation, improved controller limit logic, and improved simulation robustness. The Commercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k) is a high-fidelity transient simulation of a generic 40,000 lb thrust class commercial turbofan engine with a representative controller, developed in the MATLAB/Simulink(The MathWorks, Inc.) environment. The simulation is a nonlinear physics-based component level model that operates up to Mach 0.8 at an altitude of up to 40,000 ft, over a wide ambient temperature range. It can be run using a graphical user interface (GUI) or from the command line, and it executes faster than real time. It can simulate arbitrarily complex user-specified transients, allowing variation in power level, altitude, Mach number, and deterioration level. The engine controller is representative of those found in modern aircraft engines and is capable of operating throughout the flight envelope while preserving all necessary safety margins. Routines are included that generate state-space linear models of the nonlinear open-loop engine at any operating point, and the interface facilitates the graphical comparison of the linear and nonlinear models. The C-MAPSS40k simulation package provides easy access to health, control, and engine parameters, making it ideal for the development, implementation, and testing of advanced control and diagnostics algorithms for turbine engines.  This software is export controlled.
