Calculated Unsteady Lift and Moment Characteristics for the AGEH Hydrofoil,Based on Two-Dimensional Theory.

摘要

Unsteady lift and moment characteristics of the flap controlled hydrofoil for the AGEH PLAINVIEW have been calculated. Calculations have been done for characteristics when the flap is oscillating and when the foil and flap are fixed and heading into regular waves. Calculations were made with computer programs which determine the unsteady hydrodynamic coefficients of a hydrofoil near a free surface. Some modification of the programs were made in order to make the output format compatible with that used by NSRDC to facilitate comparison of the computed results with results of the NSRDC model tests of the PLAINVIEW hydrofoil. Numerical results are given in graphic and tabular form, and listings of the computer programs are included.
