A system and a method for adjusting and locking a control surface that is movably arranged on a wind-tunnel aircraft model and comprises a drive arrangement for driving the control surface, and a locking arrangement. The drive arrangement comprises a first drive motor, arranged in a fixed manner relative to the control surface, at least one first connecting rod eccentrically connectable to the first drive motor, and at least one lever, whose one end can be held on the first connecting rod and whose other end can be held on a fixed point of the aircraft model. The locking arrangement can be attached in a fixed manner relative to the control surface and is further designed to block a relative movement between the control surface and the aircraft model.

1. A system for adjusting and locking a control surface that is movably arranged on a wind-tunnel aircraft model, the system comprising: a drive arrangement for driving the control surface, and a locking arrangement,wherein the drive arrangement comprises a first drive motor arrangeable in a fixed manner relative to the control surface, at least one first connecting rod eccentrically connectable to the first drive motor, and at least one lever with one end that can be held on the first connecting rod and another end that can be held on a fixed point of the aircraft model in a pivotable manner; andwherein the locking arrangement is attachable in a fixed manner relative to the control surface and is adapted to block a relative movement between the control surface and the aircraft model wherein the control surface, the first connecting rod, the lever and a fixed point of the aircraft model form a four-link chain. 2. The system of claim 1, further comprising an inclinometer for determining the angle of the control surface. 3. The system of claim 1, wherein the locking arrangement further comprises a block that is attachable at a fixed point of the aircraft model and comprises a toothed surface that faces the control surface, in which system the locking arrangement comprises a body that can be slidably held in a housing on the control surface, and on a surface that faces the block comprises a tooth arrangement that corresponds to the tooth arrangement of the block. 4. The system of claim 3, wherein the body is adapted to make a deflection movement in the housing in order to establish or disestablish a positive lock with the block by a second drive motor. 5. The system of claim 1, wherein the first connecting rod is connected to the first drive motor by way of a pair of toothed wheels. 6. The system of claim 1, wherein the first drive motor is connected to a gear mechanism. 7. The system of claim 1, wherein the second drive motor is connected to a gear mechanism. 8. The system of claim 1, further two first connecting rods and two second connecting rods. 9. The system of claim 1, wherein the system is adapted to be completely installed in the control surface to be adjusted. 10. The system of claim 1, wherein the system is remotely controllable. 11. The system of claim 1, further comprising a closed-loop control device for controlling the first drive motor and the second drive motor and for acquiring and evaluating the control surface angle. 12. A method for adjusting and locking a control surface that is movably arranged on a wind-tunnel aircraft model, the method comprising: driving a first drive motor, arranged in a fixed manner relative to the control surface, which drive motor is eccentrically connected to at least one first connecting rod which moves one end of a lever, the other end of which lever is held at a fixed point of the aircraft model;determining the control surface angle; andwhen a predetermined desired angle has been reached, stopping the first drive motor, driving a second drive motor that makes a deflection movement of the body with a toothed surface on a block with a corresponding toothed surface and in this process establishes a positive lock by meshing the body with the block, and stopping the second drive motor wherein the control surface, the first connecting rod, the lever and a fixed point of the aircraft model form a four-link chain. 13. The method of claim 12, wherein in order to disestablish the positive lock between the body and the block, the second drive motor is driven in the opposite direction, or by way of a gear mechanism arranged downstream provides a reverse direction of rotation when the control surface angle is to be changed. 14. A wind-tunnel aircraft model comprising a system for adjusting and locking a control surface that is movably arranged on a wind-tunnel aircraft model, the system comprising: a drive arrangement for driving the control surface, and a locking arrangement,wherein the drive arrangement comprises a first drive motor arrangeable in a fixed manner relative to the control surface, at least one first connecting rod eccentrically connectable to the first drive motor, and at least one lever with one end that can be held on the first connecting rod and another end that can be held on a fixed point of the aircraft model in a pivotable manner; andwherein the locking arrangement is attachable in a fixed manner relative to the control surface and is adapted to block a relative movement between the control surface and the aircraft model wherein the control surface, the first connecting rod, the lever and a fixed point of the aircraft model form a four-link chain. 15. An aircraft comprising a system for adjusting and locking a control surface that is movably arranged on a wind-tunnel aircraft model, the system comprising: a drive arrangement for driving the control surface, and a locking arrangement,wherein the drive arrangement comprises a first drive motor arrangeable in a fixed manner relative to the control surface, at least one first connecting rod eccentrically connectable to the first drive motor, and at least one lever with one end that can be held on the first connecting rod and another end that can be held on a fixed point of the aircraft model in a pivotable manner; andwherein the locking arrangement is attachable in a fixed manner relative to the control surface and is adapted to block a relative movement between the control surface and the aircraft model wherein the control surface, the first connecting rod, the lever and a fixed point of the aircraft model form a four-link chain.
