THE EXPERIMENTAL WAVE RESISTANCE OF AN ACCELERATING PRESSURE BAND

A series of experiments designed to measure the wave resistance of an accelerating twodimensional air-cushion vehicle are described. A model was towed at a constant acceleration from rest over water of various depths. In addition, the effects of different levels of acceleration and cushion pressures were examined. The results are compared with linearized potential flow theory, and these show particularly encouraging agreement. The predicted humps and hollows in the curve of wave resistance versus time are verified, but with a small shift with respect to time. Also, the theoretical region of negative wave resistance in water of finite depth is demonstrated.
