Low Speed Wind Tunnel Tests to Evaluate the Aerodynamic and Thermodynamic Characteristics of VSTOL Fountains and Inlet Reingestion,

Abstract

The purpose of the test program was twofold; namely, (1) to obtain test data on fountain type flow fields that exist below hovering lift-jet type VTOL airplanes, and (2) to obtain test data on the hot-gas reingestion into the engine inlets for this type of aircraft. Measurements of dynamic pressure, flow angularity, and temperature distribution were measured in (1) the fountains produced by one, two, three, and four vertical jets, and (2) the reingestion flow field produced by a three vertical jet configuration. In addition, model interference forces and moments were measured for all vertical jet configurations. (Author)
