    Abstract: Auxiliary landing equipment for aircraft which comprises a plurality of inflatable cushions arranged in a predetermined array relative to each other and structure for securing them to the aircraft so that, in an inflated state, the cushions can contact the ground during landing or on take-off and so that, in a deflated state, the equipment can closely follow the contour of the aircraft part to which it is attached.

    Abstract: In an aircraft having an ejection seat and having a recess in its cabin defined by an overhanging wall, a collapsed bladder is arranged in the recess to provide an unobtrusive cushion for normal flight. The bladder is rapidly inflated just prior to ejection, whereupon it forcefully displaces the seat occupant''s limb to a position safe for ejection and fills the recess to prevent the airman from inserting a body member thereinto. Quick inflation expedients are disclosed, operable in an automatic ejection sequence.

    Abstract: An airlift package protection (APP) airbag may protect a package (e.g., an item or a number of items) that is dropped from within a predetermined height range by an unmanned aerial vehicle (UAV). The APP airbag may at least partially surround the package and create a container for the package. In some embodiments, the APP airbag may be inflated just prior to dropping of the package from the UAV. After inflation, the APP airbag may be at least partially sealed to reduce or inhibit deflation of the APP airbag, but possibly not to completely prevent airflow from the APP airbag upon contact with the ground. The APP airbag may exhaust some air upon impact with the ground, thereby reducing a deceleration of a package contained inside of the APP airbag.

    Abstract: The emergency landing gear actuator for aircraft utilizes a pair of airbags for rapid emergency deployment of landing gear when the conventional hydraulic actuator fails. In the retracted position, the at least one wheel of the landing gear is stored in a first cavity formed in the lower portion of the wing. The shock strut and the side strut are stored in an adjacent second cavity formed in the lower portion of the wing. First and second airbags are respectively mounted in the first and second cavities. The first airbag and the second airbag are each selectively inflatable for emergency deployment of the at least one wheel, the shock strut and the side strut. When the hydraulic actuator fails to deploy the landing gear, the first and second airbags are inflated, forcing the shock strut to rotate and position the at least one wheel in its deployed position.

    Abstract: An impact mitigation system for an aircraft and method of deploying the impact mitigation system is disclosed. A state parameter of the aircraft is obtained. The state parameter is used with an aircraft performance model to determine an acceleration capability of the aircraft. A trajectory of the aircraft is predicted using the state parameter of the aircraft and the acceleration capability of the aircraft. A location of an object with respect to the aircraft is determined and the impact mitigation system is deployed when the predicted trajectory indicates a contact with the object at a predicted contact velocity higher than a threshold velocity at a future time.
