System for controlling the speed of movement of a sliding door and associated aircraft

A system for controlling the speed of movement of a sliding door for an aircraft comprising an electromagnetic device for braking the door including a shaft and electromagnetic resistive means, and connecting means intended to be connected to the sliding door and cooperating with the transmission shaft so that when the sliding door moves in a predetermined direction, the connecting means drive the transmission shaft and the electromagnetic resistive means apply a resistive torque (Cr) on the transmission shaft to control the speed of movement of the door, wherein the resistive means are not powered by an external energy source and include a control law relating a first damping value to a first speed threshold (V1) of the speed of movement of the door, a second damping value to a second speed threshold (V2) of the speed of movement of the door higher than the first speed threshold (V1), the resistive means applying on the transmission shaft the resistive torque (Cr) equal to a first torque equal to the first damping value multiplied by the difference between the speed of movement of the door and the first threshold (V1) when the speed of movement of the door is higher than the first speed threshold (V1), and apply the resistive torque equal to the sum of the first torque and a second torque equal to the second damping value multiplied by the difference between the speed of movement of the door and the second speed threshold (V2) when the speed of movement of the door is higher than the second speed threshold (V2).
