Abstract : Experiments were conducted with the DTMB planarmotion-mechanism system to determine the normal and longitudinal components of force for DTMB Series HF-1, a systematic series of Tee foils designed to operate in the subcavitating regime. The resulting data are presented in a form applicable to the hydrodynamic design of highspeed hydrofoil craft from the standpoint of stability and control. The data are further analyzed to establish the effects of parameters such as Froude Number, depth of submergence, and aspect ratio. Comparisons are made to determine the extent to which existing theories produce agreement with the experimental data.
