Abstract : The principles of support on an air cushion and classification of air cushion devices and craft are presented. Calculations of power consumption for creation of lift and for overcoming drag are presented. The components of supporting forces and of the drag forces are analyzed and approximate methods for estimating them are discussed. Detailed calculations of flexible skirts, as well as data and specific examples are presented. A final long section is devoted to presentation of calculations, results of calculations and of wind tunnel and towing basin tests, as well as extensive supporting data in the form of graphs and nomograms.
