Prediction of Axial and Centrifugal Fan Characteristics for Large Surface Effect Vehicles

Abstract

Two digital computer programs have been formulated for predicting performance characteristics of centrifugal and axial fans which may be used to provide lift air for large surface effect vehicles. Pressure rise and flow characteristics of forwardly curved, radial, and backwardly curved centrifugal fans can be evaluated. Axial fans having either inlet flow prerotators or exit flow straighteners can also be handled in the program. Sample results are presented to illustrate the method of calculation and the nature of the results.
