Book Description
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. (Author).

Book Description
This report presents the overall results of a study of the application of rotating-diffuser centrifugal fans (RD fans) as air movers to peripheral-jet ground effect machines (GEMs). The design problems of the duct-RD fan system are discussed. It is proposed that the RD fan be used in the GEM without a conventional volute by using a radial-flow delivery technique. A study of environmental, structural, and fabrication problems of RD fans is also reported. In particular, a state-of-the-art survey of applied loads for GEMs insofar as they affect the design of an RD fan system is presented. Finally, the results of two design studies, applying the RD fan to two markedly different GEM configurations, are reported. In conclusion, results of the overall investigation indicate that RD fans are well suited to GEM applications because of high aerodynamic efficiency, low weight, and operational advantages, such as sturdiness and quietness.
