<P>PROBLEM TO BE SOLVED: To easily secure both stability and reliability of rudder surface driving, while efficiently miniaturizing an actuator for an aircraft of high output so as to be arrangeable inside a wing in which wing thinning is achieved. <P>SOLUTION: Tandem actuators (11 and 12) having piston rods (23a and 23b) where two pistons in series are arranged, are juxtaposed in a plurality in parallel. A rod end part 13 joins the piston rods (23a and 23b) of a plurality of tandem actuators (11 and 12) on the outside of case parts (24a and 24b), and is rotatably connected to a rudder surface 100. In the respective tandem actuators (11 and 12), mutual first hydraulic chambers on the opposite side of the rod end part 13 side communicate in respective two piston moving areas, and mutual second hydraulic chambers on the rod end part 13 side communicate in the respective two piston moving areas. <P>COPYRIGHT: (C)2012,JPO&INPIT |
