An air cushion vehicle is supported by forcing air into thechamber created by a skirt
Chapter 3, Problem 3.116(choose chapter or problem)
An air cushion vehicle is supported by forcing air into thechamber created by a skirt around the periphery of the vehicleas shown in Fig. P3.116. The air escapes through the 3-in. clearancebetween the lower end of the skirt and the ground (orwater). Assume the vehicle weighs 10,000 lb and is essentially rectangular in shape, 30 by 65 ft. The volume of the chamber islarge enough so that the kinetic energy of the air within the chamberis negligible. Determine the flowrate, Q, needed to supportthe vehicle. If the ground clearance were reduced to 2 in., whatflowrate would be needed? If the vehicle weight were reduced to5000 lb and the ground clearance maintained at 3 in., what flowratewould be needed?
