  • Patent number: 11679868
    Abstract: An autopilot device for attaching to and exerting forces upon a control wheel of an aircraft includes an actuator fixed with a base, the actuator adapted to move a weight between a left-most position, a center position, and a right-most position. When the weight is in the center position, the base has a center-of-gravity vertically aligned with the rotational axis of the control wheel. When the weight is left or right of the center position, the weight causes a left or right rotational moment on the control wheel, respectively. A controller is connected with the actuator and a power source and is adapted to detect flight parameters including an aircraft orientation, an aircraft heading, and a desired flight path. The controller applies power from the power source to the actuator to move the actuator and weight, thereby causing the aircraft to intercept and track the desired flight path.

  • Patent number: 11673655
    Abstract: An up-lock apparatus for landing gear of an aircraft includes a hook member configured to receive an up-lock roller pin of the landing gear when the landing gear is retracted. An up-lock actuator is coupled to the hook member and is configured to maintain the hook member in a locked state responsive to a first movement of the up-lock roller pin against the hook member to thereby prevent deployment of the landing gear. The up-lock actuator is further configured to allow the hook member to move to a released state responsive to a second movement of the up-lock roller pin against the hook member to facilitate deployment of the landing gear.

  • Patent number: 11639223
    Abstract: Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight to recover an in-flight target UAV. The towline or portion thereof may be oriented nearly vertical. The towline may have a fitting thereon. A capture mechanism on the target UAV may have one or more deployable flaps that engage with the near vertical towline and fitting. The flaps may stow to secure the target aircraft to the towline and fitting. The host aircraft may then retract the towline to pull in the target UAV to the host aircraft using a hoist system having a winch. A latching system located in a pylon of the host aircraft, which may be under a wing, may have a towline connector that engages with and secures the target UAV. The host aircraft may have multiple hoist systems for deployment and/or recovery of multiple target UAV's.

  • Patent number: 11628955
    Abstract: A tethered uni-rotor network of satellite vehicles, is made up of a central hub with multiple tethers radiating outward in a hub-and-spoke arrangement. Each tether attaches to a satellite vehicle; each having lifting airfoil surfaces, stabilizers, control surfaces, fuselages, and propulsion systems. The entire system operates in a persistent state of rotation, driven by the propulsion units on each satellite vehicle, so the airfoils generate lift which supports each satellite vehicle and a distributed portion of the weight of the central hub. As the system rotates, centrifugal forces pull each satellite vehicle outwards, which keeps each tether taught and applies tension across each of the lifting surfaces, thereby alleviating the bending moment common to fixed-wing aircraft.

  • Patent number: 11613349
    Abstract: The presently disclosed embodiments relate to vertical takeoff and landing (VTOL) aircraft that have the capability of hovering in both a “nose forward” and a “nose up” orientation, and any orientation between those two. The disclosed aircraft can also transition into wing born (non-hovering) flight from any of the hovering orientations. In addition, certain of the disclosed embodiments can, if desired, use only vectored thrust control to maintain stable flight in both hover and forward flight. No control surfaces (e.g. ailerons, elevators, rudders, flaps) are required to maintain a stable vehicle attitude. However, the disclosure contemplates aircraft both with and without such control surfaces.

  • Patent number: 11613365
    Abstract: Disclosed are various embodiments for an electromagnetic automatic deactivation device (ADD). An ADD may be used with an ejector-spring static line reserve parachute, common in low-altitude military jumps. Activating a reserve parachute from within an aircraft, while being towed by an aircraft, or when trapped inside another parachute, can result in significant injury, and may be fatal. An ADD may be added to the internal packaging of a reserve parachute to prevent its accidental activation. An ADD may be configured to sense ambient pressure, linear and rotational motion, and other data, to identify hazardous environmental conditions. An ADD may be further configured to support a towed jumper whose static line is cut, by strategically deactivating the electromagnetic assembly, and therefore activating the reserve parachute. The ADD may be modified to include the ability to override the ADD with a secondary pull on the ripcord handle.
