POWERED LIFT MODEL TESTING FOR GROUND PROXIMITY EFFECTS,
Abstract
The effect of ground proximity on the performance of powered lift vehicles was investigated on simple models using two different testing methods. Single and double-jet models representing VTOL configurations and an air-cushion model with peripheral jet were tested both in the wind tunnel where a stationary plate immersed in the flow was used to represent the ground and on a special rig allowing the models to be moved over a fixed-ground plate. The lift and centre of pressure location have been determined with both techniques for various model heights above the ground-plate over a range of momentum coefficients. Results obtained with both methods are compared. (Author)
