Abstract : This study is a part of a hydrofoil research program now being carried out by various agencies under the auspecies of the Department of the Navy, Bureau of Ships. The function of this program is to meet an obvious need for quantitative goals and specifications to guide the design of hydrofoil systems and the components going into these systems. This report is concerned primarily with the theory of controlled hydrofoil supported craft and the practical considerations of implementing the automatic control system. The analysis and design which follows is intended to provide an understanding of the possibilities and limitations of the performance of submerged foil hydrofoil craft, and hence a rational basis for choosing the most effective control system. In addition the problems and proposed solutions of controlled hydrofoil design are formulated and explicated in more detail than has been done previously. (Author)
