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.
