The Transonic Jet Flap-A Review of Recent Results 751089

Experimental results are used to explore the physical mechanism of lift augmentation and the drag due to lift, and to show the inadequacies of the Taylor-Spence thin jet model of the jet flap. In the jet-flapped wing-fuselage configuration, 3D effects, particularly due to the wing-fuselage interference, are shown to have major effects on the performance of the jet flap. At large sweeps the 3D vortical nature of the shock-induced separation is shown to also play a dominant role.
