APPARATUS FOR PITCH FEEDBACK OF CONTROLLABLE PITCH PROPELLER

摘要

The present invention relates to a pitch feedback apparatus for a variable pitch propeller, and more specifically, to a pitch feedback mechanism, which minimizes complexity of a feedback structure identifying a pitch change of a blade and exactly transfers an angle position of a variable pitch propeller to a hydraulic unit controller through a follow-up member, thereby comparing an actually changed pitch with an ordered pitch based on immediate decoding of a pitch position of an actual blade in the hydraulic unit controller to precisely process pitch control of the blade.
