EXPERIMENTAL INVESTIGATION OF NEAR- SURFACE HYDRODYNAMIC .FORCE COEFFICIENTS FOR A SYSTEMATIC SERIES OF TEE HYDROFOILS, DTMB SERIES HF-1

摘要

Experiments were conducted with the DTMB Planar-Motion-Mechanism System to determine the normal and iongitu4iaai components of force for DTMB Series HF-1, a systematic series of Tee foils designed to operate in the subcavitating regine. The resulting data are presented in a from applicable to the Rydrodynarnic design of high-speed 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 p£ sub mergence, and aspect ratio. Comparisons are made to determine the extent to which existing theories, produce agreement with the experimental.
