<p>PROBLEM TO BE SOLVED: To provide a moving blade device for a missile capable of: performing a supersonic flight, which can minimize a load to be applied to a driving device in a manner to correspond to the movement of an aerodynamic center without restricting the layout of the moving blade and the revolving shaft; and improving the degree of freedom of the layouts of the moving blade and the revolving shaft, and the downsizing of the driving device.SOLUTION: In the moving blade 4 of a missile, as the aerodynamic center is caused to move from the axis AX of a revolving shaft 8 to the rear edge side by a supersonic flight, a first rear edge part 12 is separated by an explosive device 16, and the wing chord of the moving blade 4 is shortened, when deformed into a wing shape having a second rear edge part 14 at a rear edge, so that the aerodynamic center is made to approach the axis AX of the revolving shaft 8.</p> |
