Wind Tunnel Aerodynamics By Dr. Charles Trefny 20 Sept 2002
Aerodynamics The field of science and engineering dealing with the effects of air moving around solid objects.
Aerodynamicists Predict what will happen in a given situation using physical laws, math, wind-tunnels and computers
Air has mass and obeys Newton’s laws. 100 gallons of air has a mass of about 1 pound. We must speed-up, slow-down, or change the direction of the air to generate a force. Look for this in the following examples of aerodynamics…
Wind tunnels are used to predict the amount of force generated by solid objects. This helps aerodynamicists choose the proper size for things such as wings, spoilers, and parachutes. Information obtained in wind tunnels is used to improve the design of anything affected by wind. Wind-Tunnels come in all shapes and sizes…
