Effect of Configuration on the Measured Performance of a Power Augmented Wing-in-Ground Effect.
Abstract
An analysis is performed to determine the effects of configuration upon the performance of a power augmented ram wing in ground effect (PAR WIG) aircraft. The results of two testing programs are investigated for changes in performance due to changes in flap angle, fan angle, angle of attack, aspect ratio, wing loading, thrust-weight ratio, fan density, and water roughness. Performance is assessed through the vehicle's transport efficiency and heave, along with discussion of the acceleration characteristics of these varied configurations. Aside from the numerical conclusions which are made concerning the vehicle parametrics, it was found that operation of the vehicle in waves of significant height up to 1/10 span does not significantly degrade a PAR WIG's performance. Numerical results are included to aid performance prediction for a given configuration. (Author)
