Flow Visualization Studies of the XFV-12A.

Abstract

The XFV-12A incorporates thrust augmentation to generate propulsive lift. Under the influence of forward flight the lift jets are subject to bending, which produces shed vortices that induce velocities at the aircraft. Additionally, operations in ground effect during hover and for small forward velocities can result in reingestion of engine exhaust gases. The objectives of this thesis were twofold. The first was to investigate analytically aspects of the vortex shedding phenomenon through the application of potential flow around the lifting surfaces of the aircraft. Secondly, experimental analysis was performed to determine the unique reingestion properties of the XFV-12A operating statically under various wing and canard configurations.
