AN INVESTIGATION OF GROUND EFFECT ON VERTICAL TAKEOFF AIRCRAFT.

Abstract

The theoretical solution for the flow beneath V/STOL aircraft was extended to include tilted jet configurations. A laboratory model was constructed to test the effect of variation of the parameters governing the flow. Free streamline plots, pressure coefficients on the ground and fuselage and velocity profiles in the nozzles were determined from hot-wire anemometer traverses and micromanometer readings. Experimetal data compared favorably with the theoretical determinations. (Author)
