ACOUSTIC ENGINEERING CONSIDERATIONS IN THE DESIGN OF A TRACKED AIR CUSHION VEHICLE (TACV)

The TACV seems to be leading the field of potential high-speed ground transportation systems in the United States. This paper briefly discusses the acoustic design of a proposed 150 mph, 60 passenger prototype vehicle by LTV Aerospace Corporation. It was some 120 feet long and intended to travel in a channel-section guideway. The vehicle was levitated by a continuous series of air-cushion arrays, underneath, with a similar arrangement along the sides to provide guidance. Two fans at the front supplied air to the cushions via a duct down each side of the vehicle. The cushion concept comprised a shallow, inverted pan suspended from a flexible air-bag. The gap between the pan lip and the guideway was 0.14". Stringent environmental requirements were imposed by DOT to allow operation in urban areas, and to provide unexcelled passenger comfort.
