THE AERODYNAMICS OF HIGH SPEED GROUND TRANSPORTATION

This is a comprehensive book covering the topics of ground vehicle aerodynamics, tunnel or tube and air cushion aerodynamics. It is the first book to treat all these categories, and with the current interest in new transportation systems it should have immediate use by design engineers. The complexity and diversity of topics covered presents a thorough treatment of each item. Essential features are discussed and information necessary for preliminary aerodynamic design of ground vehicles is provided. Speeds up to 300 mph are currently being considered for ground transportation systems, and at these speeds the drag, lift, and side-forces can be of the order of the weight of the vehicle. The basic principles of air cushion vehicles are given and discussed. Both plenum and peripheral jet air cushions are considered along with the effects of forward speeds. A major difficulty with the air cushion vehicle is its stability, and the author gives an introduction to the static and dynamic stability associated with such vehicles. A significant portion of this book is devoted to the aerodynamics of vehicles in tunnels and tubes. At speeds in the range of 300 mph compressible flow analysis must be used to describe some of the flow fields caused by a vehicle moving at such speeds in the confined environment of a tunnel or a tube.
