Commercial Modular Aero-Propulsion System Simulation 40k (C-MAPSS40k)
Developed in the MATLAB/Simulink environment, C-MAPSS40k is a high-fidelity transient simulation of a generic commercial turbofan engine with a 40,000-pound thrust. The nonlinear physics-based component-level model operates up to Mach 0.8 over a wide ambient temperature range and executes faster than real time. The model can be run from the command line or by using a graphical user interface.
U.S. Government Purpose Release
Cryogen Storage Integrated Model (CryoSIM)
CryoSIM provides input power and dry mass estimates for insulation and hardware used in in-space applications to maintain cryogens in storage. System heat load estimations and associated propellant loss masses can also be generated.
U.S. Government Purpose Release
Centrifugal Off-Design Performance (CCODP) Compressor
CCODP is a one-dimensional off-design performance prediction code used for centrifugal compressors. Correlations account for the following types of loss: inlet guide vane, impeller incidence, shock, skin friction, blade loading, trailing edge, clearance, vaneless and vaned diffuser friction, recirculation, and disk friction.
U.S. Release Only
ACOD Multistage Axial-Flow Compressor Off-design
A companion tool to Glenn Research Center's ACD software (LEW-17448), ACOD is streamline analysis code for predicting the off-design performance of multistage axial-flow compressors. Flow, blading, and loss are modeled similarly to ACD.

Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS)
T-MATS is open source software code. The Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS) is a Simulink toolbox intended for use in the modeling and simulation of thermodynamic systems and their controls. T-MATS contains generic thermodynamic and controls components that may be combined with a variable input iterative solver and optimization algorithm to create complex systems to meet the needs of a developer. Developement of this tool was completed on behalf of the NASA Aviation Safety Program's Vehicle Systems Safety Technologies (VSST) project located at the Glenn Research Center in Cleveland, OH.
Open Source
Advanced Ducted Propfan Analysis Code (ADPAC)
Developed by the Allison Engine Company under contracts with Glenn Research Center, ADPAC solves tightly coupled internal/external flows through future-concept short-duct turbofan engines.
U.S. Release Only
Generalized Fluid System Simulation Program (GFSSP), Version 701
The Generalized Fluid System Simulation Program (GFSSP) is a general software tool that can perform complex fluid flow analysis in a wide variety of applications, including those related to chemical processing, gas processing, power plants, hydraulic control circuits, and various kinds of fluid distribution systems. The tool models liquid fuel phase changes that include compressibility and mixture thermodynamics and allows the user to apply and vary "what-if" effects of external influences.
