Abstract

An actuator setup is disclosed which includes a body, at least one control surface located on the body for enabling to control the flow of fluid by moving relative to the body, at least one actuator produced from an electro-active polymer material that is located between the body and the control surface and changes its form depending on electrical energy, thereby triggering the control surface, at least one strengthener located on the actuator, enabling the actuator to change its form, a strengthener located on the actuator so as to be in connection with the body and having a front strengthener and a rear strengthener located on the actuator so as to be oppositely positioned with the front strengthener.

First claim

The invention claimed is:

1. An actuator setup ( 1 ) comprising:
a body ( 2 ),
at least one control surface ( 3 ) located on the body ( 2 ) for enabling control of a flow of fluid during an air vehicle's flight by moving relative to the body ( 2 ),
at least one actuator ( 4 ), located between the body ( 2 ) and the control surface ( 3 ), which changes form depending on electrical energy and thereby triggering the control surface ( 3 ),
at least one strengthener ( 5 ) located on the actuator ( 4 ) for enabling the actuator ( 4 ) to change form and having a first front strengthener ( 501 ) located on the actuator ( 4 ) so as to be in connection with the body ( 2 ) and a first rear strengthener ( 502 ) located on the actuator ( 4 ) so as to be oppositely positioned with the front strengthener ( 501 ),
at least two electrodes (E) that enable the actuator ( 4 ) to be triggered, one of the at least one actuator ( 4 ) located between the electrodes (E) and consisting of more than one layer of dielectric elastomer thereby changing form when electrical energy is applied and thereby triggering the control surface ( 3 ),
a connection element ( 9 ) for connecting the strengthener ( 5 ) and the actuator ( 4 ) to each other, the connection element ( 9 ) located on the strengthener ( 5 ) so as to remain between the strengthener ( 5 ) and the actuator ( 4 ) and enabling the strengthener ( 5 ) to be connected to the actuator ( 4 ), and
at least one additional front strengthener ( 501 ) and at least one additional rear strengthener ( 502 ) in the form of a protrusion, located as a point on the body ( 2 ) and/or the control surface ( 3 ), extending outward from the body ( 2 ) and/or the control surface ( 3 ), enabling the actuator ( 4 ) to reduce regional deformation and/or to change regional form and each of which being able to be powered identically or differently depending on the electrical energy they are subjected to for changing the regional form of the actuator ( 4 ).

2. The actuator setup ( 1 ) according to claim 1 , comprising at least one motor ( 7 ) located on the body ( 2 ) for mechanically triggering the strengthener ( 5 ) to enable the control surface ( 3 ) to change position, and a control unit ( 6 ) for controlling the operation of the motor ( 7 ).

3. The actuator setup ( 1 ) according to claim 1 , wherein the at least one additional front strengthener ( 501 ) and/or at least one additional rear strengthener ( 502 ) can be positioned a distance apart from each other that depends on a configuration predetermined by the user for changing the length and/or tension of the actuator ( 4 ).

4. The actuator setup ( 1 ) according to claim 1 , wherein the strengthener ( 5 ) has a rough surface enabling the front strengthener ( 501 ) and/or the rear strengthener ( 502 ) to be held by increasing the friction force on the actuator ( 4 ).

5. The actuator setup ( 1 ) according to claim 1 , comprising at least one switch mechanism ( 8 ) located on the actuator ( 4 ) for enabling the distance between the more than one front strengthener ( 501 ) and/or the more than one rear strengthener ( 502 ) to remain identical.

6. The actuator setup ( 1 ) according to claim 1 , comprising more than one strengthener ( 5 ), at least one of which having a different geometry than the other.

7. The actuator setup ( 1 ) according to claim 1 , wherein the actuator ( 4 ) located between the electrodes (E) consists of one or more layers of square or circular shaped dielectric elastomer.

8. The actuator setup ( 1 ) according to claim 1 , wherein the body ( 2 ) is a wing, vertical stabilizer, horizontal stabilizer or an airframe.

9. The actuator setup ( 1 ) according to claim 1 , comprising a control unit ( 6 ) that controls each of the front strengtheners ( 501 ) and each of the rear strengtheners ( 502 ) individually according to user-given commands and enables the strengtheners to be triggered separately by electrical energy.

10. The actuator setup ( 1 ) according to claim 9 , wherein the control unit ( 6 ) that enables the actuators ( 4 ) to be triggered receives commands from a flight crew or autopilot software.
