Publication number: 20250075549Abstract: The system for controlling the speed of opening a sliding door for an aircraft including a mechanical braking device for the door including a transmission shaft and a centrifugal absorber including a resistance shaft connected to the transmission shaft, and linking means that are designed to be connected to the sliding door and to cooperate with the transmission shaft so that when the sliding door moves in a predetermined direction, the linking means drive the transmission shaft and the centrifugal absorber applies a resistance torque to the transmission shaft in order to control the speed of movement of the door. The system includes a speed reducer connecting the resistance shaft to the transmission shaft so that the speed of rotation of the resistance shaft is greater than that of the transmission shaft when the sliding door moves in the predetermined direction.Type: ApplicationFiled: January 10, 2023Publication date: March 6, 2025Applicant: SAFRAN ELECTRONICS & DEFENSEInventors: Daniel Hors, Célina Bur

Publication number: 20250067111Abstract: The system for controlling the speed of movement of a sliding door for an aircraft comprises a means for electromagnetically braking the door including a transmission shaft and electromagnetic resistive means. The resistive means are autonomous and include a control law relating a first damping value to a first speed threshold of the speed of movement of the door, a second damping value to a second speed threshold of the speed of movement of the door, the resistive means applying on the transmission shaft the resistive torque equal to a first torque proportional to the first damping value when the speed of movement is higher than the first speed threshold, and applying the resistive torque equal to the sum of the first torque and of a second torque proportional to the second damping value when the speed of movement is higher than the second speed threshold.Type: ApplicationFiled: January 10, 2023Publication date: February 27, 2025Applicant: SAFRAN ELECTRONICS & DEFENSEInventors: Daniel Hors, Aurélien Bellier
