What is GECAT Modeler?

GECAT (pronounced GEE-CAT) Modeler is a state-of-the-art, user-friendly graphical user interface designed and developed by ManTech SRS Technologies, Inc. to assist engineers, university professors/students, and instructors in performing air breathing propulsion cycle design and analysis. It has incorporated the proven Rolls Royce Turbine Engine Reverse Modeling Aid Program (TERMAP) into a graphical drag and drop interface which allows you to interactively configure engine cycles, construct trade studies, build compressor maps, match data, graph data, and generate detailed summary reports. GECAT Modeler was developed under a Small Business Innovative Research (SBIR) contract for the US Army Aviation and Missile Command (AMCOM) and Air Force Research Laboratory (AFRL), under the advisory direction of the Joint Army Navy NASA Air Force (JANNAF) Propulsion Organization. In addition to TERMAP, GECAT Modeler has plug-in modules available for Kill Vehicle Design, Booster Sizing, and Manufacturer Cycle Deck programs. MSRST can tailor GECAT Modeler to use other propulsion analysis programs, if required, to meet specific customer needs.

What is TERMAP?

Rolls Royce Turbine Engine Reverse Modeling Aid Program is designed to serve two functions : as a gas turbine engine gas path and performance model, and as a gas turbine engine design study reverse modeling aid. As a performance analysis program, TERMAP is a design/off-design steady-state engine performance calculation for turbojet, turbofan, and turboshaft gas turbine cycles burning JP-4 fuel. As an engine design study program, TERMAP expands these capabilities into a data matching program where a defined cycle can be forced to adjust its design to satisfy inputs of known engine performance parameters.

Benefits from Using GECAT Modeler

GECAT Modeler makes it easier to tackle the complex job of developing and analyzing air breathing propulsion engines. It has incorporated TERMAP into a drag and drop interface which gives users hands-on control in configuring engine cycles. Engine cycle analysis can be performed without having prior TERMAP training, since default input values are available. Default engine cycle templates are available to use in configuring a new engine cycle. Users can also rapidly configure and manipulate cycle characteristics to analyze a myriad of cycles and operating conditions. The GECAT Modeler graphical user interface is organized using a project tree and several tabbed windows. These tabbed windows include: Cycle, Maps, Matching, Trades, Graphs, and Report.
