  • Movable aircraft engine cowling
    Patent number: 5035379
    Abstract: A movable cowling for an aircraft is disclosed having a stationary fairing portion attached to an engine support pylon and a movable cowling portion. The movable cowling portion defines a generally longitudinally extending slot to accommodate the stationary fairing portion when the movable cowling portion is in its closed position to enclose the aircraft engine. The movable cowling portion, which may be generally annular in shape and have a generally "C"-shaped cross sectional shape, is attached to the engine by way of a telescoping beam. A portion of the beam is attached to the movable cowling and a second portion of the beam is attached to the engine. The movable cowling moves in a direction generally parallel to the longitudinal axis of the engine such that it has no portions requiring lifting about a hinge axis. A locking mechanism is provided between the movable cowling portion and the stationary fairing to lock the movable cowling portion in its closed position.

  • Device for the detection of the position of the thrust reverser of a turbojet engine
    Patent number: 4437783
    Abstract: Device for the detection of the position of the thrust reverser of a turbojet engine and its locking element, which includes an element integral with the moving part of the reverser, which cooperates with a mechanical locking device and a stationary electrical detection device for detecting the position of an element integral with the reverser and its locking device.The locking device, mounted pivotingly on a support element has on one side of a pivoting axle an arm which is connected with a control cylinder and on the other side a strap having an axle which may be engaged by a hook of the element integral with the moving part of the reverser, moving in a rectilinear motion of translation, the locking device carrying another axle parallel to its pivoting axle and upon which a lever is articulated.
