摘要： Nose landing gear arrangements including a folding follow-up door for reducing airflow noise for aircrafts, aircrafts including such nose landing gear arrangements, and methods for making such nose landing gear arrangements are provided herein. In one example, a nose landing gear arrangement includes a wheel assembly and a main strut. The main strut is operatively coupled to the wheel assembly and is configured to extend outside of the fuselage substantially along a generally vertical plane. A folding follow-up door is pivotally coupled to the main strut and extends to the fuselage. The folding follow-up door includes a first door section and a second door section that extend outwardly in directions away from each other to define an unfolded position. The folding follow-up door is foldable to move the first and second door sections towards each other about the generally vertical plane to define a folded position.

摘要： A secure corset is applied in particular to the immobilization in the maximum opening position of an aircraft landing gear cage hatch. The corset has two half-shells that are able to enclose the piston of the actuator having an axis coincident with the common longitudinal axis of the half-shells once they are closed around the piston. Locking pins are able to hold the half-shells around the actuator. The corset also has a casing secured to at least one of the half-shells and equipped with a hooking unit that is able to be coupled to a fixed point on the structure. A structure for varying the distance between the casing and the hooking unit are able to move the hooking unit away from or towards the corset along the common longitudinal axis of the half-shells.

摘要： A system for opening and closing a door for a landing gear compartment of an aircraft includes a connection between the landing gear and the door with a first system forming an actuator mounted on the landing gear and a second system forming an actuator mounted on the door. The two systems form actuators connected to each other by at least one fluid communication device such that actuating the first system causes the actuation of the second system.

摘要： A quiet landing gear door and methods are presented. A landing gear door comprises a trailing edge and a leading edge and is operable to deploy to a landing gear door deployed position. A door flap comprises the trailing edge and is hinged to the landing gear door. The door flap deflects toward a landing gear strut to a door flap deployed position in response to deployment of the landing gear door. A leading edge section comprises the leading edge and is coupled to the door flap. The leading edge section deflects toward the landing gear strut to a leading edge deployed position in response to deployment of the landing gear door.

摘要： An aircraft landing gear door assembly has a plurality of doors. The doors include a first door (1) mounted for rotational movement between closed and open positions about a first generally longitudinal axis (11) and a transverse door (3) mounted for rotational movement between closed and open positions about a generally horizontal axis (13) that is transverse to the longitudinal axis (11). The provision of the transverse door (3) can allow the length of the first door (1) to be reduced from that which would otherwise be required to allow passage of the landing gear.

摘要： A wheel pants structure is provided for aircraft having landing gear including wheel and axle means which are supported in a substantially fixed position relative to the aircraft fuselage. The pants structure is in the form of a housing defined by fixed wall means having an opening therein adapted to be closed by a pair of pivotal door elements. The housing means including the fixed wall means and the door elements is adapted to completely enclose the wheel when the door elements are in the closed positions thereof. When the door means are moved to the open positions thereof, a portion of the wheel means is exposed for engagement with an underlying support surface for the aircraft. The door means may be moved between the open and closed positions thereof mechanically, electrically, hydraulically or pneumatically and may be actuated either manually from within the aircraft cabin or automatically.
