THE LIFT ON A TWO-DIMENSIONAL AUGMENTOR WING,

Abstract

The performance of an augmentor wing has been examined with a simplified model that consists of a thin airfoil with a jet-augmented flap and a sink located at the hinge of the flap. The analysis is based on a small disturbance theory. The results for the basic configuration, namely the airfoil with a jet-augmented flap, agree very well with those obtained by other authors. It shows that the lift on the airfoil can be increased appreciably with a jet-augmented flap. Suction on the upper surface of the airfoil can also induce additional lift on the system. This induced lift becomes more efficient as the suction slot moves towards the trailing edge. However, the lift decreases slightly as the jet momentum flux increases and the jet becomes more 'stiff'.
