초록

Displacements of output portions 35, 36 of a pair of piezoelectric actuators 25, 26 arranged spanwise in a flap drive apparatus are magnified by a displacement magnification mechanism 27 so that a swing arm 28 is driven in swinging fashion with large amplitude. A flap 22 attached to the trailing edge of a blade 21 by way of a connecting rod 30 connected to a tip of the swing arm 28 is driven in vertical angular displacement fashion. The displacement magnification mechanism 27 possesses an eccentric shaft 40 has a first shaft 41 and second shaft 42 with o...

1. A rotor blade flap drive apparatus comprising:a flap attached to a trailing edge of a blade so as to permit vertical angular displacement of the flap; a pair of actuators housed within the blade and having output portions which are operable to be displaced in opposite phases; a swing arm having a base portion coupled to the respective output portions of the pair of actuators so as to be angularly movable, and having a tip at an end of the swing arm opposite to the base portion and operable to swing in a lead direction and a lag direction; and a connec...
