The potential of the propulsive wing in developing very high lift coefficients for STOL operation has been investigated with several nozzle aspect ratios. The use of the propulsive wing/canard appears to offer an approach to managing the large negative pitching moments associated with trailing-edge blowing. A full-span model of a wing/canard concept representing a fighter configuration has been tested at STOL conditions in the Langley 4 by 7 Meter Tunnel. The results of this test are presented, and comparisons are made to previous tests of the same configuration tested as a semispan model (Stewrt, 1983). Also presented are data showing the effects of large flap deflection and the effect of nozzle span. Comparisons of the test results with jet-flap theory are made and indicate good agreement.
