Fixed Hydrofoil Control Surface.

Abstract

The patent application relates to a fixed hydrofoil control surface for use as a rudder or pitch control fin attached to a vehicle, and having an elliptical hydrofoil shaped body with a pair of jet discharge slots formed parallel and along the trailing edge. Liquid, forced out of one or the other slots, deflects the main flow from over the hydrofoil by the Coanda effect to one or the other side to create a positive or negative control force without the need of deflecting the control surface.
