Abstract : In anticipation of the growing use by the U. S. Navy of hydrofoils as gun boats, patrol boats, and as antisubmarine warfare craft, a study was initiated to formulate the mathematical models required for simulating the hydrofoil as a pilot-controlled training situation and as a target or own-ship vehicle. This report summarizes the work performed during the course of the study. The principal work of the study resulted in two technical reports: the Mathematical Model Report (Technical Report: NAVTRADEVCEN 1630-2, Vols. I-III) and the Performance Criteria and Test Report (Technical Report: NAVTRADEVCEN 1630-1). The FINAL REPORT includes a description of the analog computer simulation which was assembled and tested using the information contained in the two technical reports. The U. S. Navy Hydrofoil Patrol Craft PC(H)-1, HIGH POINT, was used as the basis for this phase of the work. Equations, scale factors and wiring diagrams for the simulation are presented. It is now known that some of the present-day limitations of the equations and simulation technique will yeild to further work. Consequently, one suggestion is that further effort be applied to developing a method of simulating foilborne turns in realistic seas. In addition, the problem of simulating hull wave inpact forces in real time merits attention. (Author)
