Abstract: A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.

Abstract: A system for maintaining a fleet of aircraft batteries located at multiple airports. The system may be configured to obtain charge information and battery health information for individual batteries within the fleet of aircraft batteries from charging containers located at individuals ones of the multiple airports. The charge information may include charge statuses of the individual batteries and/or the battery health information may characterize the degradation of the individual batteries over time. The system may determine predictions of one or more batteries to be re-allocated and/or to receive maintenance based on the battery health information. The system may generate a battery management plan including the one or more predictions recommending one or more batteries to be re-allocated and/or to receive maintenance.

Abstract: A structurally-integrated battery pack may comprise an outer skin, an inner skin, structural foam, battery cells, and/or other components. Structural foam may be disposed between the outer skin and the inner skin. The structural foam may include battery voids and/or one or more cooling channels. Battery cells may be disposed within the battery voids. The battery cells within the battery voids and the structural foam may form layers. The layers may comprise a first layer including a first structural foam layer, a second layer including a first battery disposed within a first battery void, a third layer including at least a partial structural foam layer, and/or other layers. The partial structural foam layer may at least partially form a cooling channel. The outer skin, the inner skin, the structural foam, and/or the battery cells may be incorporated into a structural or non-structural element of an aircraft and/or vehicle.

Abstract: A parallel hybrid aircraft comprising an electric propulsion system and a combustion propulsion system. The electric propulsion system may include a motor, one or more batteries, and a first propeller. The combustion propulsion system may include a combustion engine and a second propeller. The combustion propulsion system may be decoupled and independently operable from the electric propulsion system. A flight control system may control which of the electric propulsion system and/or the combustion propulsion system provides propulsion and/or thrust for ground movement, takeoff, forward flight at cruising altitude, and/or landing.

Abstract: An oblique rotor-wing aircraft may be capable of vertical take-off and landing, subsonic cruise, transonic cruise, and/or supersonic cruise. The oblique rotor-wing aircraft may comprise one or more of a fuselage, a rotor-wing, a thrust-vectored propulsion system, a locking mechanism, and/or other components. The rotor-wing may be rotatably coupled to the fuselage. The rotor-wing may rotate about an axis in a first flight mode for vertical takeoff and landing. The oblique rotor-wing aircraft may include a thrust-vectored propulsion system that drives the rotation of the rotor-wing about the axis. The thrust-vectored propulsion system may include multiple, separately operable propulsion systems coupled to the rotor-wing and/or the fuselage. The oblique rotor-wing aircraft may comprise a locking mechanism that locks the rotor-wing at an angle oblique to the fuselage responsive to initiation of a second flight mode. The rotor-wing may be fixed at an angle oblique to the fuselage during the second flight mode.
