OPTIMAL SHAPE OF A PLANING SURFACE AT HIGH FROUDE NUMBER

A planing surface moving at high Froude number throws up a jet that is responsible for the leading term in the drag. By shaping the surface appropriately, the jet can be eliminated. The drag is thereby reduced by a factor of order (Fr) to the minus 2 power. The paper shows how this can be done for a two-dimensional planing surface consisting of two flat plates. It is found that the lengths of the plates must have a ratio dependent upon their angles of inclination. Then the angles that maximize the lift coefficient are determined.
