What mechanically actuates the nose gear door?

The nose gear door of the Dassault Falcon 7X is mechanically actuated by rollers on the torque link arm. This system utilizes the movement of the gear during extension and retraction to control the opening and closing of the nose gear door. When the landing gear is lowered, the torque link arm's rollers engage with the door mechanism, ensuring that the door opens smoothly and closes securely as the gear retracts.

This mechanical actuation system provides a reliable and straightforward way to synchronize the movements of the nose gear and its corresponding door without the complexity and potential failure points associated with hydraulic or pneumatic systems. Additionally, the use of electric motors is not suitable for this particular application, as the torque link design, which is more directly linked to the gear's movement, offers a more efficient and lighter solution for controlling the door's operation.
