Abstract: Embodiments of the present disclosure provide an entry assist system for an aircraft doorway. The system includes a securement member configured to be secured into at least one aperture of the doorway, a handle portion pivotally attached to the securement member, and a releasable locking feature for locking the handle portion. A mounting device is used for securing the stationary member to an existing aperture in the doorway and for removing the entry assist system when no longer needed. The securement member forms a stationary portion along an inner edge of the doorway. The handle portion includes a hub configured for rotating about an axle that is coupled to an interface of the securement member. The hub and interface interconnect to form the releasable locking feature for locking the handle in a collapsed position adjacent the securement member or in an extended position protruding outside the doorway.

Abstract: An aircraft door is slidable along a door path between open and closed positions. The door is guided by one or more tracks. Riders carried by the door are engaged to the tracks. Each rider includes a roller held for rotation about a roller axis which is fixed relative to the door. Each roller axis extends generally horizontally and generally transverse to the track. Each track includes a first portion extending generally parallel to the aircraft fuselage and a second portion having a continuously curving transition to the first portion and extending partially inboard from the first portion. The second portion of the track guides the door into and out of the opening in the fuselage, allowing the door to achieve a substantially flush condition when in its closed position.

Abstract: The damper is comprised of a set of core rotor magnets arranged in an opposing north/south configuration. A conducting material cylindrically encircles the rotor magnets. A set of stator magnets laterally encircle the conducting material and are arranged in the same manner as the rotor magnets. A system of gears are coupled to the damper shaft and control the rotation of the rotor magnets such that they can be positioned relative to the stator magnets to set up the desired damping torque. As the rotor and stator magnets of opposite polarity approach each other, the eddy-current in the rotating conducting material increases causing the conducting material to generate a field in response to the eddy-current. The damping torque is caused by the magnetic force generated when the induced field in the material and the stator/rotor field attempt to line up.

Abstract: A retractable aircraft step module comprises a streamlined fairing having a recess for receiving a retractable step member which is connected to the fairing by spaced apart pivot links which together with the step member and the body member form a four bar linkage. The linkage includes a deflectable pivot connection between one of the links and the step member which provides a biasing force to maintain the step member in the retracted position. The deflectable pivot connection is provided by a pivot beam mounted on the step member and including a counterdeflection adjustment for preselecting the maximum biasing force. The step member and the fairing are adapted to mount on the exterior of an aircraft fuselage and are preferably constructed of reinforced plastic.

Abstract: An aircraft in which the fuselage and wings are configured in a blended wing design has a door opening in the fuselage adjacent the wing and a door assembly for closing the door opening. The door assembly includes a door having an exterior panel that conforms to the shape of the aircraft at the location of the door opening when the door is closed and having an interior structure configured in a series of steps. The door is movable between a closed position in which an upper edge of the door panel is adjacent an upper edge of the door opening and an open position in which the door panel lies substantially within the wing and in which the upper edge of the door panel is adjacent an upper surface of the wing and spaced from the fuselage. When the door is in the open position, the steps form a stairway leading from the fuselage up and out of the aircraft to the upper surface of the wing. Preferably, the door assembly also includes a movable wing panel which is slaved to the door such that, as the door is moved from the closed to the open position, the wing panel moves to uncover an opening in the wing upper surface through which the door passes to reach its open position.
