1. An aircraft deicing system comprising:

  • at least one motor operative to drive at least one eccentric mass in rotational motion; and

    at least one displacer fixed to at least one location on at least one aircraft surface and rotatably supporting a shaft about which said at least one eccentric mass moves in rotational motion, thereby producing inertial forces which are applied via said shaft to said at least one displacer, causing said at least one displacer to displace said at least one aircraft surface in a plurality of directions at each of said at least one location, said plurality of directions corresponding to changing positions of said eccentric mass as it moves in rotational motion about said shaft, thereby causing disengagement of ice from said at least one aircraft surface.
