There are Beginner's Guides that accompany each of the software packages to explain the science and math. And for teachers, we have developed almost 200 activities 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.
There are 15 different program available....and some of them include:
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. 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 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.
RocketModeler: This program lets you design and study the flight of a model rocket. You can vary the size of the rocket, the number of fins, and the materials used to construct the rocket. You can choose from a variety of available model rocket engines and test fly your rocket on the computer. The program computes the stability of your design and the flight trajectory. Output includes the maximum altitude which the rocket achieves. You can then compare the computed and actual performance of your model rocket.
KiteModeler: This program lets you design and study the flight of a kite. You can select from five different types of kites and then vary the length, width and types of materials used to construct the kite. You then trim the kite by setting the length of the bridle and tail and the position of the knot attaching the control line to the bridle. Finally, you test fly your kite on the computer by setting the wind speed and the length of control line. The program computes the aerodynamic forces, weight, and stability of your design and the shape of the control line as it sags under its own weight. Output includes the maximum altitude which the kite achieves. You can then compare the computed and actual performance of your kite design.
SoundWave: Using the SoundWave applet, students learn about sounds and how they are transmitted through the air. A "bug" emits a sound that is detected by a microphone. The sound waves are animated so that you can see how sound is transmitted. You can move the bug and vary his speed, which demonstrates the Doppler effect of frequency change for a moving sound source. You can make the bug move faster than the speed of sound to see the formation of Mach waves through the flow.
Atmosphere Applet: This program lets you study how pressure, temperature, and density change through the atmosphere. You can study the atmosphere of the Earth or of Mars. Since speed of sound depends on the atmospheric gas and the temperature, you can also output the local speed of sound and the Mach number for a selected aircraft velocity. You can either input a selected altitude, or change altitude using an aircraft slider.
