Top Educational & Science Software for NASA

HEALPix (Hierarchical Equal Area isoLatitude Pixelization) is a software for pixelization, hierarchical indexation, synthesis, analysis, and visualization of data on the sphere of a sphere.As suggested in the name, this pixelization produces a subdivision...

The Airfoil View Panel is a simulated view of a wing being tested in a wind tunnel with air moving past it from left to right. Students change the position and shape of the wing by moving slider controls that vary the parameters of airspeed, altitude,...

The GasLab is a series of computer animations which demonstrate all the possible combination of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and...

A "bug" generates a series of sound waves which are transmitted at the speed of sound. You can vary the speed of the bug from zero to twice the speed of sound (Mach 2) by using a slider. The change of wavelength associated with the doppler effect at lower...

KiteModeler works in three modes: Design Mode, Trim Mode, or Flight Mode. In the Design Mode you pick from five basic types of kite designs. You can then change design variables including the length and width of various sections of the kite. You can also...

You can change design variables including the size, and shape of the rocket body, the fins, the nose cone. You can also select different materials for each component. RocketModeler 3 calculates the weight of the rocket and determines the drag coefficient...

Variables include the Mach number, static to total pressure, temperature, and density ratios, dynamic to static pressure ratio, critical area ratio, corrected airflow per unit area, Mach angle, and Prandtl-Meyer angle. Specifying any one variable...

TunnelSys combines three computer programs, the design and wind tunnel test programs, and a post-processing program to plot the results from the wind tunnel test. With the post-processing program you can compare the results from multiple wind tunnel test...

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...
