MAPSS - Modular Aero-Propulsion System Simulation

The Modular Aero-Propulsion System Simulation (MAPSS) is a flexible turbofan engine simulation environment that provides easy access to health, control, and engine parameters through a graphical user interface (GUI). The key function of MAPSS is to provide the user with a graphical simulation environment in which to develop advanced control and diagnostic algorithms and quickly test them on a generic turbofan engine simulation. MAPSS can be used to generate state-space linear models, from which the user may create a piecewise linear controller. MAPSS can also run transient simulations. This capability allows the user to test the performance of his or her algorithms on a validated, and verified, generic engine model. Both military and commercial turbofan engine versions of MAPSS exist.

The commercial version, C-MAPSS, represents a high-bypass engine capable of 90,000 lbf thrust with a realistic full-authority digital engine controller (FADEC) and runs faster than real-time. The military version is representative of a low-bypass, high-pressure ratio engine with an advanced multivariable controller.

MAPSS and C-MAPSS are available upon request from NASA's Software Repository through NASA GRC's Technology Transfer and Partnership Office.
