Abstract: A drone delivery system hub and method for sending for take-off and receiving for landing unmanned aerial vehicles (UAVs). The drone delivery system hub includes a center shaft frame, a parcel-conveying system supported by the center shaft frame, structural arms coupled to and extending outward from the center shaft frame in a spoke-like configuration, drone-conveying systems each supported by one of the structural arms, and a linking conveyor span. The drone-conveying system conveys the UAVs along a length of a correspond one of the structural arms toward and away from the center shaft frame. The linking conveyor span selectably rotates to different orientations between different pairs of the structural arms, selectively conveying a UAV thereon between any two of the structural arms. The linking conveyor span is located above the parcel-conveying system such for the UAV thereon to deposit and retrieve parcels from the parcel-conveying system.

Abstract: The present invention is a drone for spraying liquid such as pesticides, fungicides, herbicides, plant growth regulators, plant defoliators, and fertilizers over field crop. The drone comprises: a frame with a slender rigid beam in the middle and two base structures at the two ends, a rigid tube with an array of nozzles on elongated stems and the rigid tube is suspended below the beam structure with retractable wires, at least three propellers on motors with arms that are rotatably mounted to each of the two base structures of the frame, a power source positioned in one of the bases, at least one distance detector for measuring height of the drone above the ground, an antenna for sending and receiving communication signals, an electronic control system to operate motors and sensors, a container for a liquid material with a caped opening for refilling and an air pump to maintain a positive pressure in the container and electronic valve to allow liquid in the container under pressure to be released through a transfer line to be sprayed from the nozzles, and a remote controller for operating the drone. The invention provides a specialized drone that is able to spray liquid solutions over a wide strip of the field at a height close to crop canopy to achieve high efficiency and precision and reduced drift of sprays while the drone flies at a relatively high above the crop canopy for safe operation and avoid damage to crop by air turbulence.

Abstract: An aircraft has a wing providing the main lifting surface for the aircraft. The wing has a structure supporting an aero-dynamic surface, and the wing has a weight, the wing structure being unable to support its own weight when the aircraft is stationary and under a load of 1 g so as to cause structural failure of the wing.

Abstract: Various systems and methods for providing and deploying a power harvesting drone are described herein. A power harvesting drone includes a motor assembly; an energy replenishment coupler; a processor communicatively coupled to the energy replenishment coupler; and a memory storing instructions, which when executed by the processor cause the processor to: operate the power harvesting drone to navigate a predetermined path; determine that a power supply used to operate the power harvesting drone is below a threshold of remaining power; identify an opportunistic energy source; and deviate from the predetermined path to replenish at least a portion of the power supply from the opportunistic energy source using the energy replenishment coupler onboard the power harvesting drone.

Abstract: An aircraft system includes a wing member and a plurality of unmanned aircraft systems selectively connectable to the wing member. The wing member has a generally airfoil cross-section, a leading edge and a trailing edge. The unmanned aircraft systems have a connected flight mode while coupled to the wing member and an independent flight mode when detached from the wing member. In the connected flight mode, the unmanned aircraft systems are operable to provide propulsion to the wing member to enable flight. The unmanned aircraft systems are operable to be launched from the wing member to perform aerial missions in the independent flight mode and are operable to be recovered by the wing member and returned to the connected flight mode. Thereafter, in the connected flight mode, the unmanned aircraft systems are operable to be resupplied by the wing member.
