Abstract: A system in a fixed-wing aircraft includes inflatable buoyant bags. Each of the inflatable buoyant bags is arranged to conformally cover a corresponding pylon attachment of the fixed-wing aircraft in a deflated state. The system also includes a tank storing pressurized gas and a controller to control inflow of the pressurized gas from the tank into the inflatable buoyant bags to increase buoyancy of the fixed-wing aircraft and to control outflow of the pressurized gas out of the inflatable buoyant bags to decrease buoyancy of the fixed-wing aircraft.

Abstract: The present invention includes an apparatus for preventing aircraft rollover upon a water landing comprising: a deployable first and/or second boom affixed by a first end to the aircraft and capable of deployment substantially perpendicular to a longitudinal axis of the aircraft; and a first and/or second air bladder attached to a second end of the first and/or second boom, wherein the first and/or second air bladders are configured to inflate when an aircraft lands in the water, wherein deployment of the first and second boom and air bladder prevents aircraft rollover upon water landing; or a deployable keel affixed by a first end to the aircraft and capable of deployment substantially perpendicular to a longitudinal axis and opposite a rotor of the aircraft upon a water landing, wherein the keel is sized to prevent aircraft rollover upon deployment; or both.

Abstract: Apparatus and associated methodology contemplating an emergency flotation system for floating a flying machine on a body of water. The system includes a water sensor mounted to the flying machine. An inflation device is configured to produce an appropriate amount of pressurized gas in response to the water sensor detecting a presence of water. An inflatable flotation device is in fluid communication with the inflation device, to receive the pressurized gas and thereby become inflated. The flotation device is configured, when inflated, to impart a buoyant force to the flying machine in the water.

Abstract: An unmanned aerial vehicle (UAV) airbag may protect protection for a UAV or other objects when making contact with one another. The UAV airbag may at least partially surround the UAV while allowing the UAV to remain at least partially operable. In some embodiments, the UAV airbag may be inflated just prior to making contact with another object. After inflation, the UAV airbag may be at least partially sealed to reduce or inhibit deflation of the UAV airbag, but possibly not to completely prevent airflow from the UAV airbag upon contact with another object. The UAV airbag may exhaust some air upon impact, thereby reducing a deceleration of a UAV contained inside of the UAV airbag.

Abstract: The present invention relates to a control method for inflating at least one float of a buoyancy system. During a mode (MOD1) of automatic inflation in flight, calculation means determine whether a predetermined ditching condition is true during a step (STP1) of predicting a forthcoming impact. During a step (STP2) of characterizing said impact, at least one predicted component of a ditching speed is determined. During an automatic inflation step (STP3), each float is automatically inflated in flight when at least said ditching condition is true and when each determined predicted component is less than a corresponding speed threshold.

Abstract: A de-linking assembly includes an actuator defining a chamber and an inlet, a piston slideably disposed within the chamber, link coupled to the actuator, and a ram disposed between the piston and the link. The link defines a stress concentration features and a load point on a side of the link on a side of the stress concentration feature opposite the actuator. The ram is seated to the piston and against the load point such that air introduced into the chamber through the inlet applies force to the piston and ram sufficient to sever the link by inducing stress in the stress concentration feature.

Abstract: An aircraft parachute system includes an aircraft that has a fuselage, a pair of wings, a tail section and a plurality of engines. A plurality of parachute units is provided and each of the parachute units is coupled to the aircraft. Each of the parachute units is selectively deployed when the aircraft experiences an in-flight emergency such that the plurality of parachute units inhibits the aircraft from crashing. A plurality of balloon units is provided and each of the balloon units is coupled to the aircraft. Each of the balloon units is selectively deployed when the aircraft experiences the in-flight emergency. In this way each of the balloon units floats the aircraft in water when the aircraft lands in water.
