An Experimental Study of the Effect of a Low Speed External Flow on a Coanda Effect Flap.

Abstract

An experimental study of the effect of a low speed air flow external to the blowing flow over a coanda effect flap was conducted. The test model had a 122 ft/sec external flow over an airfoil surface which terminated with a coanda effect flap. The flap had an internal flow velocity of 452 ft/sec at the coanda nozzle exit. The model was equipped to make possible vertical force measurements and schlieren photography of the flap area. The force measurements showed that the net vertical force produced by the combined internal and external flows was equal to the net vertical force of the individual flows. (Modified author abstract)
