Vought XF5U

Vought XF5U, a fighter, is manufactured by Vought, designed by Charles H. Zimmerman, primarily used by United States Navy, developed from Vought V-173 prototype. This aircraft has low aspect ratio with low takeoff and landing speed but high top speed. Usually, a wing with such a low aspect ratio will suffer from poor performance due to the degree of induced drag created at the wingtips. Aircraft with high aspect ratio wings has reduced vortices but the wing will also compromise the maneuverability and roll rate of aircraft, so the XF5U attempted to overcome the tip vortex problem using propellers, which are arranged to rotate in opposite direction to the tip vortices. These propellers have very limited ability to tilt up and down to aid the aircraft in maneuvering. However, by 1946, the XF5U project was long over its expected development time, and well over budget, as jet aircraft coming into service, the Navy canceled the project on 17 March 1947 with only two aircraft constructed.
