EngineSim is a simulator that models the design and testing of jet engines and the effects of engine type on aircraft speed and range. The program works in two modes: Design Mode or Tunnel Test Mode. In the Design Mode, you can change design variables including the flight conditions, the engine size, the inlet performance, the turbo machinery compressor and turbine performance, the combustors or burner performance, or the nozzle performance. For a turbofan engine design you can also vary the fan performance and the bypass ratio. When you have a design that you like, you can switch to the Tunnel Test Mode, where you can vary only the flight conditions (airspeed, altitude, and throttle setting). The software was created to illustrate an example of the research being conducted at the NASA Glenn Research Center and is designed to be an intuitive tool to supplement and enhance math and science curricula.

System Requirements: Windows 95, Windows NT or Macintosh, Standalone software or web browser / internet access
