A common modeling and data environment enables you to use digital information to design and analyze your tunnel in-context to surrounding terrain and infrastructure.
You can optimize your tunnel layout combining digital terrain model data with digital point cloud and image data in a single, integrated environment. Our solution utilizes parametric 3D modeling combined with comprehensive structural analysis tools allowing you to optimize your tunnel design. Bentley offers a comprehensive civil modeling, structural analysis and information management environment addressing the needs of modern tunnel design and supporting tunnel infrastructure.
Free Software Free Software Glenn Research Center In an effort to foster hands-on, inquiry-based learning in science and math, the NASA Glenn Research Center has developed a series of interactive computer programs for students. All of the programs are Java applets which run in your browser, on-line, over the World Wide Web. The programs can also be downloaded to your computer so that you can use them without being on-line. The programs are in the and are constantly being modified and upgraded based on your input. We have also developed a series of Beginner's Guides that accompany each of the software packages to explain the science and math. You can access the Beginner's Guides at the bottom of this page.
Powerboat design software for tunnel hulls and Vee hulls - design Sport tunnel, Offshore catamarans, Circuit racing tunnels (F1 /. Rocscience Phase2 Tunnel Design Software is widely used for the analysis and design of underground tunnels. Applications include tunnelin.
And for teachers, we have developed almost 200 to test the student's knowledge of the material. These grade-specific activities have been developed by teachers during summer workshops and are aligned with science and math standards. We would like to know if you are using any of these simulators, activities, or the accompanying Beginner's Guides. Please notify of any experiences you have with these products.

(80KB) FoilSim III computes the theoretical lift and drag of a variety of airfoil shapes. The user can control the shape, size, and inclination of the airfoil and the atmospheric conditions in which the airfoil is flying. The program includes a stall model for the airfoil, a model of the Martian atmosphere, and the ability to specify a variety of fluids for lift comparisons. The program has graphical and numerical output, including an interactive probe which you can use to investigate the details of flow around an airfoil. ( 455KB) EngineSim is a simulator that models the design and testing of jet engines.
The program works in two modes: Design Mode or Tunnel Test Mode. Yu Gi Oh Gx Sound Duel 1 more. 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. Crack Particle Illusion 3.0 4 - And Reviews. 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 which simulates the testing of a jet engine on a test stand. You can then vary the test altitude, flight speed and throttle setting. Several existing engines are also modeled in EngineSim.
Critical Program Settings Not Found In Registry. (111KB) Using the TunnelSim applet, students learn more about the aerodynamics of wind tunnels by changing the shape and flow conditions through the tunnel. This program can be used for the preliminary design of an open return wind tunnel. Speeds are limited to low subsonic operation and the program warns the student of high speed flow and possible separation in the diffuser.
