Abstract:
A system for deflecting an aerodynamic control surface, comprising:a main segment having first and second surfaces disposed inwardly from the aerodynamic control surface; a spar disposed between the first and second surfaces of the main segment; a first piezoelectric actuator coupled at a first end to a first flexure member and rotatably coupled to the main segment at a second end, the first flexure member having a first end coupled to the first surface of the main segment and a second end coupled to the spar, the first flexure member operable to amplify a linear motion of the first piezoelectric actuator; and a second piezoelectric actuator coupled at a first end to a second flexure member and rotatably coupled to the main segment at a second end, the second flexure member having a first end coupled to the second surface of the main segment and a second end coupled to the spar, the second flexure member operable to amplify a linear motion of the second piezoelectric actuator.
