Abstract
An aircraft deicing system including at least one motor operative to drive at least one eccentric mass in rotational motion and at least one displacer coupled to at least one location on at least one aircraft surface and coupled to the at least one eccentric mass such that forces produced by the rotational motion of the eccentric mass are applied to the at least one displacer, causing the at least one displacer to displace the at least one aircraft surface in a plurality of directions at each of the at least one location, thereby causing disengagement of ice from the at least one aircraft surface.
Claims23
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 coupled to at least one location on at least one aircraft surface and coupled to said at least one eccentric mass such that forces produced by said rotational motion of said eccentric mass are applied 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, thereby causing disengagement of ice from said at least one aircraft surface.
An aircraft comprising:
- an airframe including at least one aircraft surface;
- at least one motor operative to drive at least one eccentric mass in rotational motion;
- and
- at least one displacer coupled to at least one location on at least one aircraft surface and coupled to said at least one eccentric mass such that forces produced by said rotational motion of said eccentric mass are applied 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, thereby causing disengagement of ice from said at least one aircraft surface.
An aircraft deicing system comprising:
- at least one ice thickness sensor for sensing an ice thickness responsive characteristic of at least one aircraft surface;
- at least one selectably controllable ice disengager operative to cause ice to disengage from said at least one aircraft surface;
- and
- at least one controller responsive to an output of said ice thickness sensor indicating said ice thickness responsive characteristic of said at least one aircraft surface for varying at least frequency of said selectably controllable ice disengager.
An aircraft deicing system according to claim any of and wherein
- said at least one motor comprises a plurality of motors, each of which is operative to drive an eccentric mass in rotational motion;
- and
- said at least one displacer comprises a plurality of displacers, each of which is coupled to a location on said aircraft surface and coupled to said eccentric mass such that forces produced by said rotational motion of said eccentric mass are applied to said displacer, causing said displacer to displace said aircraft surface in a plurality of directions at said location.
