Wind Tunnel Testing Now Available To The Common Man

This how-to guide provides detailed instructions for construction and use of a subsonic wind tunnel. The wind tunnel is best used for science fair projects in grades 9— Did you know that every single plane, helicopter, and spaceship used in America today has been tested in a wind tunnel? A wind tunnel is a chamber through which high-speed air is passed. Models of aircraft or actual aircraft can be mounted in a wind tunnel so that flight conditions can be simulated and engineers can study how well a design will fly. Wind tunnels have been used for over years. In fact, the Wright brothers used one to help them figure out how to build the world's first successful aircraft, the Wright Flyer.
Search the history of over billion web pages on the Internet. It contains over fifty projects, from every scientific field, each of which has been tested and successfully performed by a num- ber of amateurs. Almost all of them require only cheap and easily obtain- able materials and apparatus: yet they range from making your own atom smasher, seismological observatory, mathematical computor, or X-ray machine, to how to cultivate harmless bacteria. The author will be well known to the thousands of readers of The Scientific American in this country for his monthly articles on amateur experi- ments, which provide the materials for this book. It should be a welcome addition to the school library and provide hours of fascinating reading for anyone with more than a passing interest in science and scientific experimentation.
