Wright Brothers built their wind tunnel and screened more than 200 different wing designs. They selected 35 wings for detailed testing, obtaining lift and drag coefficients using balances of their own design. With this software you can duplicate all of...

TunnelSim solves the continuity equation for a geometry that you specify using sliders and input boxes. The analysis is limited to incompressible, inviscid, one-dimensional flows, and the program warns the user if the diffuser angle exceeds a separation...

EngineSim 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...

World Wind lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, as if you were really there....

A new computer screen saver made available by the European Space Agency now allows computer users to watch spectacular, almost real-time images of our Sun. The images, coming directly from 1.5 million kilometres away in space, will flash on your computer...
