Abstract
Installation of powered actuators in the leading edge of a control surface in order to have a better weight distribution. The systems described herein propose an actuation system with a static ground structure used to move a control surface of an aircraft. The actuation system, and the ground structure are aligned with the center of rotation of the control surface, providing the aircraft with flutter suppression. This proposal is an approach to use the actuator in a place favorable to the mass balancing and reducing or even dismissing the usage of mass balancing, saving weight and cost.
Claims9
A control surface actuation system comprising:
- a) an actuator installed inside a control surface located in a leading edge of the control surface;
- and
- b) a ground structure, coupled to the actuator, aligned with a center of rotation of the control surface;
- c) wherein the actuator comprises an electromechanical actuator.
Actuator installation in the leading edge of a control surface, comprising:
- an actuator providing for a better mass distribution of a control surface;
- wherein the actuator translates with control surface rotation.
An aircraft comprising:
- a control surface having a leading edge and a center of rotation;
- an electromechanical actuator installed inside the control surface and disposed in the leading edge of the control surface;
- and
- a ground structure, mechanically coupled to the actuator, aligned with the center of rotation of the control surface.
