Abstract
Disclosed herein is an exemplary embodiment of a system for driving a slat of an aircraft. The system includes first and second hinge support elements of a wing structure, a first arm device, a second arm device, and a third arm device. Also disclosed is an aircraft having the system, an aircraft wing having the system, and a method for driving a slat of an aircraft. The system utilizes a particular configuration of connection junctions, which rotatably connect the arm devices and the hinge support elements.
Claims16
A system for driving a slat of an aircraft, comprising:
- a first hinge support element of an aircraft wing structure;
- a second hinge support element of the aircraft wing structure;
- a first arm device;
- a second arm device;
- and
- a third arm device;
- wherein the first arm device is rotatably connected by an associated first connection junction to the first hinge support element, comprising a second connection junction configured to be rotatably connected to a rear portion of the slat, having a steady curved shape between the first connection junction and the second connection junction, and comprising a third connection junction arranged between the first and second connection junction, of the first arm device;
- wherein the second arm device is linearly extendable, being rotatably connected by an associated first connection junction to the second hinge support element, comprising a second connection junction being configured to be rotatably connected to a front portion of the slat, and comprising a third connection junction arranged between the first and second connection junction, of the second arm device;
- and
- wherein the third arm device is rotatably connected by an associated first connection junction to the third connection junction of the first arm device, and being rotatably connected by an associated second connection junction to the third connection junction of the second arm device.
