First Claim
1. A dynamically controllable force-generating device, comprising:
- a force-generating motive surface;
a motor operatively coupled to the force-generating motive surface to move at least a portion of the force-generating motive surface to generate a force;
at least one controlling motive surface spaced apart from the force-generating motive surface; and
a motor operatively coupled to the at least one controlling motive surface to move at least a portion of the controlling motive surface to change at least one of a direction and a magnitude of the force generated by the force-generating motive surface.

Abstract
A dynamically controllable force-generating device configured to be incorporated into a vehicle, such as an aircraft or a ship, or an energy-harvesting device, such as a wind turbine, is disclosed. The dynamically controllable force-generating device includes a force-generating motive surface, a motor operatively coupled to the force-generating motive surface to move at least a portion of the force-generating motive surface to generate a force, at least one controlling motive surface spaced apart from the force-generating motive surface, and a motor operatively coupled to the at least one controlling motive surface to move at least a portion of the controlling motive surface to change at least one of a direction and a magnitude of the force generated by the force-generating motive surface.

18. A method of dynamically altering fluid dynamic properties of a force-generating device comprising a force-generating motive surface and at least one controlling motive surface spaced apart from the force-generating motive surface, the method comprising:
-
introducing the force-generating device into a fluid flow having a free-stream velocity; moving at least a portion of the force-generating motive surface at a first surface speed; and changing the at least one controlling motive surface from a first state to a second state, wherein; the force-generating motive surface generates a first resultant force having a first direction and a first magnitude when the controlling motive surface is in the first state, the force-generating motive surface generates a second resultant force having a second direction and a second magnitude when the controlling motive surface is in the second state, and at least one of the second direction and the second magnitude is different than a corresponding one of the first direction and the first magnitude. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
