By Larry Reithmaier Why are there no supersonic airlines? What are the problems confronted by designers of 2,000 mph airplanes? How close are we to building a hypersonic, or Mach 5, aircraft? Find out the answers to these and many more fascinating questions in this introductory guide to the compelling world of high-speed flight. Here, Larry Reithmaier explains in easy-to-understand terms the principles of flight near Mach 1 (the speed of sound) as well as supersonic and hypersonic flight beyond Mach 1. Packed with nearly 200 helpful illustrations, photographs, and diagrams, this intriguing book includes information on compressibility, drag, and other aerodynamic concepts; the jet engine (gas turbine engine); high-speed airplanes at low speeds; and aircraft stability and control. Mach 1 and Beyond also covers super-performance aircraft such as the supersonic transport (SST), the SR-71 Blackbird, the McDonnell F-15 Eagle, and General Dynamics' F-111.
