Abstract:

The characteristics of a jet-flapped wing of aspect ratio 6 are presented, discussed, and evaluated for STOL application. Again, as for high- aspect-ratio AR 20 jet-flapped wings, a range for the most economical jetflap operation is well defined. The angle of attack as an efficient means of lift production loses its usefulness with low-aspect-ratio jet-flapped wings, whereas the optimum jet-deflection angle seems hardly affected. A most efficient jet-flap application for STOL calls for a complete integration of the lifting and propulsive systems. In the range of most economical jet-flap operation, semiempirical relationships predict parameter changes accurately enough for practical purposes.
