A two-dimensional, linearized theory for the purpose of designing high speed hydrofoils is presented. The theory is intended for the development of a foil which will overcome the problems associated with the supercavitating foil at takeoff and at moderate speeds. To accomplish this, a streamlined foil is considered in such a way that part of the profile shape of the foil is prescribed and on the remaining part of the foil the pressure distribution is given. A mixed boundary-value problem is therefore formulated and solved. The resulting foil is intended to be used at takeoff and at moderate speeds. A few examples are given. With the help of control devices, the prescribed part of the foil shape is expected to be used as a supercavitating foil at high speeds.
