PRELIMINARY STUDIES OF THE APPLICATION OF PERIPHERAL FANS TO GROUND EFFECT MACHINES

Abstract

This report describes the concept, development of applicable theory, and experiments performed to date with the Frost fan. Essentially a rotary vane air pump, the Frost fan lends itself to installation around the periphery of ground effect machines for generation of the lifting cushion pressure. Structural and space utilization advantages are inherent in this concept, and enhance the potentially high overall efficiency gained through almost complete elimination of duct losses. Test data and theory are also presented on the application of crossflow blowers to the peripheral fan concept. Similar information on energy recovery through recirculation of lift cushion air is included, with indication of shortcomings in practical applications of recirculation.
