Of EngineSim, FoilSim and TunnelSyS for undergraduates.Īpplet, students learn about the process of wind tunnel testing. The properties in regions of isentropic flow. There are programs to solve for the flows across shock wavesĪnd expansion fans, the flow through crossed and reflected shocks, and
Undergraduate engineering students learn about the basics ofĪerodynamics and propulsion. Here is a group of Java programs which were designed to help Warns the student of high speed flow and possible separation in the diffuser. Speeds are limited to low subsonic operation and the program This program can be used for the preliminary design Shape and flow conditions through the tunnel. Several existing engines are also modeled in EngineSim.Īpplet, students learn more about the aerodynamics of wind tunnels by changing the You can then vary the test altitude, flight speed and When you have a design that you like, youĬan switch to the Tunnel Test Mode which simulates the testing of a jet engine For a turbofan engine design you can also vary the fan
The flight conditions, the engine size, the inlet performance, the turbo machineryĬompressor and turbine performance, the combustors or burner performance, or In the Design Mode, you can change design variables including The program works in two modes: Design Mode That models the design and testing of jet engines. Which you can use to investigate the details of flow around an airfoil.ĮngineSim: ( 455KB) EngineSim is a simulator The program has graphical and numerical output, including an interactive probe The program includes a stall model for the airfoil, a model of the MartianĪtmosphere, and the ability to specify a variety of fluids for lift comparisons. The user can control the shape, size, and inclination of the airfoil and theĪtmospheric conditions in which the airfoil is flying. Please any experiences you have with these products.Ĭlick on the icon below for more information about the major programs.įoilSim III computes the theoretical lift and drag of a variety of airfoil shapes.
We would like to know if you are using any of these simulators, activities, or Have been developed by teachers during summer workshops and are aligned with science To test the student's knowledge of the material. And for teachers, we have developed almost 200 You can access the Beginner's Guides at theīottom of this page. We have also developed a series of Beginner's Guides thatĪccompany each of the software packages to explain the science and math. Public domain and are constantly being modified and The programs can also be downloaded to your computer so that you can use them without All of the programs are Java applets which run in your browser, on-line, over NASA Glenn Research Center has developed a series of interactive computer programsįor students. In an effort to foster hands-on, inquiry-based learning in science and math, the
