Abstract:

This report presents the results of a theoretical study to determine the lift, total moment and hinge moment acting on a fully wetted, oscillating hydrofoil with an oscillating flap in two-dimensional, linearized, potential flow. The flow was assumed to be noncavitated, but no limitations were placed on the values of Froude number or depth-to-chord ratio. The solution takes full account of the surface waves caused by the hydrofoil motion. Results are presented in graphical and tabular form. Lift, total moment, and hinge moment are given as functions of reduced frequency with Froude number, depth-to-semichord ratio and hinge position as parameters. Author
