There are two types of wind tunnels high-speed, used to test high velocity vehicles - rockets, jet aircraft, etc.; and low-speed, used to test vehicles which travel at a rate of under 300 mph, which represent the majority of products developed - such as automobiles, propeller aircraft, etc. This book covers all aspects of the technology from the design and use of wind tunnels to the complex instrumentation required to analyze the effects that the tunnel has on the product being tested.
