Abstract:

IT IS CONJECTURED THAT A PRACTICAL MEANS OF OBTAINING A SHIP OF MINIMUM WAVE RESISTANCE WHICH ALLOWS FOR BOUNDARY-LAYER SEPARATION, PROPELLERHULL INTERACTION AND FORM RESISTANCE IS TO ADOPT A PROVEN AFTERBODY, SAY A Taylors Standard Series form, and to calculate the corresponding optimum forebody from Michells integral. By assuming an affinely related forebody, the minimization of Michells integral is reduced to finding the minimum of a function of several variables. Certain integrals which occur as coefficients are evaluated on an IBM 704 digital computer. The computer program and its accuracy are briefly described. Optimum forebodies for various values of the Froude number and other parameters are discussed. Author
