TWO-DIMENSIONAL PROBLEM OF THE MOTION OF A SUPERCAVITATING PLATE UNDER THE FREE SURFACE OF A HEAVY LIQUID

The paper deals with the theoretical problem of motion of a supercavitating plate under the free surface of a heavy liquid. It is assumed that the angle of attack is small, and that the Froude numbers are high, but finite. Linearizing assumptions make it possible to consider the waves formed on the surface extremely small. The author determines the wave drag of a flat supercavitating plate moving at a certain depth with large but finite Froude numbers, with a low angle of attack for the case of an infinite cavity ( SIGMA = 0 ). Use is made of the Cochin function taken for the corresponding solution in aa weightless fluid. It is shown that the finiteness of the cavity has an effect on wave formation.
