  • Patent number: 11192640
    Abstract: An emergency extension system for extending at least one aircraft undercarriage, the emergency extension system comprising both electromechanical actuators, each electromechanical actuator having an identification component arranged to allocate an identifier to said electromechanical actuator, which identifier depends in particular on a function performed by said electromechanical actuator, and also an electrical card having a delay component arranged to delay actuation of a the electromechanical actuator by an actuation delay that depends on the identifier allocated to the electromechanical actuator, the electromechanical actuators of the emergency extension system thus being arranged to be actuated in succession in an actuation sequence that is defined by the actuation delays.
    Type: Grant

  • Patent number: 10982720
    Abstract: A device (1) for connecting an end of a first shaft to an end of a second shaft, the end of the first shaft having a radial groove. The device includes a body (2) having a bore (21) into which the end of the first shaft can be introduced, a locking pin (3) movable with respect to the body (2) between a locked position, in which the pin (3) projects into the bore (21) such that, when the end of the first shaft is received inside the bore (21), the locking pin (3) is engaged in the radial groove in the end of the first shaft, and an unlocked position. In the unlocked position, the locking pin (3) is disengaged from the radial groove in the end of the first shaft, and an elastic return member (4) urges the locking pin (3) into the locked position.

  • Publication number: 20200378447
    Abstract: The invention relates to a device (1) for connecting an end of a first shaft to an end of a second shaft, the end of the first shaft having a radial groove, the device comprising:—a body (2) having a bore (21) into which the end of the first shaft can be introduced,—a locking pin (3) mounted so as to be movable with respect to the body (2) between a locked position, in which the pin (3) projects into the bore (21) such that, when the end of the first shaft is received inside the bore (21), the locking pin (3) is engaged in the radial groove in the end of the first shaft in order to prevent the end of the first shaft from being removed from the bore (21), and an unlocked position, in which the locking pin (3) is disengaged from the radial groove in the end of the first shaft so as to allow the end of the first shaft to be introduced into the bore (21) or to allow the end of the first shaft to be removed from the bore (21), and—an elastic return member (4) for urging the locking pin (3) into the locked position
