A passive guidance mechanism enables smooth guiding to a desired position; and a flying object landing system enables smooth guiding to and landing at a desired position. A pair of guide rails are arranged side by side with a space therebetween, and are provided so that the space increases toward one set of tips of the guide rails. One guide rail is supported so as to be rotatable about a first shaft extending in a direction perpendicular to a plane including the guide rails, at or near the tip of the guide rail. The other guide rail is supported so as to be rotatable about a second shaft extending in a direction perpendicular to the plane including the guide rails, at or near the tip of the guide rail.

A drone including a front section, a wing structure supported by a rotor located behind the front section, and a propeller at the rear. The wing structure including two wings rotating the rotor, the wing structure being able to move between a flight configuration, in which the rotor is immobile relative to the front section and the propulsion provided by the propeller, and a flight configuration with the wing structure rotating, in which the rotor is rotated relative to the front section, the rotor being connected to the front section with a possibility of orienting its axis of rotation relative thereto in order able to direct the drone in the rotary wing structure configuration by acting on said orientation.

A wing system is provided for an air vehicle, the air vehicle having a fuselage including a fuselage longitudinal axis. The wing system includes a set of wings, configured for transitioning between a stowed configuration and a deployed configuration. The set of wings includes a first said wing having a first wing tip, a first wing longitudinal axis, and a first pivot axis; and a second said wing having a second wing tip, a second wing longitudinal axis, and a second pivot axis. The first pivot axis and the second pivot axis are non-coaxial. In the stowed configuration, the first wing and the second wing are in overlying relationship such that at least a majority of a pressure surface of one wing is facing a suction surface of the other wing, and the first wing tip is spaced from the second wing tip by a first lateral spacing. In the deployed configuration, the first wing is oriented with respect to the second wing such that the first wing tip is spaced from the second wing tip by a second lateral spacing greater than the first lateral spacing. The transitioning includes a pivoting operation, including: pivoting the first wing about the first pivot axis between the stowed configuration and the deployed configuration; and, pivoting the second wing about the second pivot axis between the stowed configuration and the deployed configuration.

Methods and apparatus to deploy unmanned aerial vehicles (UAVs) by kites are disclosed. An example apparatus to deploy a UAV includes a tether line to support the UAV, a tensioner operatively coupled to the tether line, and a kite operatively coupled to the tether line to support the tether line for deployment of the UAV.

A device for catching and launching a guided UAV, the device comprises a supporting post, a horizontal shaft mounted on the post, and a lever is mounted on the horizontal shaft and can make a full revolution around a horizontal axis within a vertical plane, the lever is equipped with an engagement/disengagement device a means for interaction with the UAV catching device and an optical member, preferably arranged on the lever, for determining a location of the lever interaction means by an optical guidance system of the UAV. The lever comprises two coaxial portions, one is the engagement/disengagement device, and the second is a bar, wherein one end of the bar is coupled to the horizontal shaft, while another end thereof is connected to the engagement/disengagement device. The bar and the engagement/disengagement device are connected by a hinge that enables their fixation in a coaxial state and allows offset the axis of the engagement/disengagement device relative to the axis of the bar within a rotation plane of the lever. The horizontal shaft is equipped with a means for accumulating and/or dissipating the kinetic energy of the UAV, the lever is fixed on the shaft and can provide an elastic offset of the interaction means of the engagement/disengagement device within a plane perpendicular to the rotation plane of the lever, the interaction means configured to provide mutual locking/unlocking with the UAV catching device.

Various embodiments of the present disclosure provide a rotorcraft-assisted system and method for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system includes a modular multicopter, a storage and launch system, an anchor system, a flexible capture member, and an aircraft-landing structure. The multicopter is attachable to the fixed-wing aircraft to facilitate launching the fixed-wing aircraft into free, wing-borne flight. The storage and launch system is usable to store the multicopter (when disassembled) and to act as a launch mount for the fixed-wing aircraft by retaining the fixed-wing aircraft in a desired launch orientation. The anchor system is usable with the multicopter, the flexible capture member, and the aircraft-landing structure to retrieve the fixed-wing aircraft from free, wing-borne flight.

An aircraft launching system and method include a first lifting sub-system including a first tether that removably couples to an aircraft, and a second lifting sub-system including a second tether that couples the first lifting sub-system to the second lifting sub-system.

An unmanned aerial vehicle launch tube that has a tube, a sabot disposed in an interior of said tube, said sabot having a first clasp tab, and a clasp detachably coupled to said first clasp tab and contacting an inner circumferential wall of said tube so that said clasp is rotationally constrained by the inner circumferential wall and said first clasp tab.

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.
