Abstract : This report presents the basic theory and some numerical results on the inverse problem for fullycavitating hydrofoils. The problem is treated by the twodimensional linearized theory of steady cavity flows. The problem of optimum hydrodynamic design of cavitating blades or foils is explored and the conditions required to insure realistic cavity flows are examined. As a result of these considerations three methods for profile design are put forward. Two of these methods are treated numerically. It is found that once the pressure distribution has been prescribed, the shape of the profile depends upon the design cavitation number. The camber decreases as the cavitation number increases. This report does not discuss the numerical methods used in the study. They are given separate documentation in AD-606 062. (Author)
