Aerodynamics and Flying Qualities of Jet V/STOL Airplanes

A summary of information on airplane aerodynamics, ground effects, propulsion system aerodynamics, stability and control, and flying qualities of jet V/STOL airplanes - both direct jet lift and lift fan configurations is presented. The information is applicable to high-speed fighter-type airplanes. Research work in the following areas is reviewed:

1. 1.
   Wind tunnel and other experimental research on jet-induced effects (including ground effects) on the aerodynamics and stability and control in the VTOL, STOL, hovering, and transition ranges of flight.
2. 2.
   Experimental research on propulsion aerodynamics in the hovering and very low speed ranges of flight.
3. 3.
   Flight-test experience on the flying qualities of several jet V/STOL airplanes.
