A fully automated towing, alignment and hangar system suitable for an offshore operation helicopter includes a quick mooring device, a wide-angle camera installed on a rear wall of the quick mooring device, a longitudinal towing device, a DSP control unit, an MCU control unit, a helicopter and a mooring bar thereof. An alignment method based on above system includes following steps of acquiring an attitude image of a steering wheel, calculating a helicopter yaw angle and a steering wheel deflection angle, calculating position coordinates of the steering wheel, a first wheel and a second wheel in a deck coordinate system, judging boundaries relative to a towing indication line, extracting an optimal path suitable for the movement of the helicopter, calculating lateral and longitudinal movement position control commands, driving the movement of the helicopter, and repeating the above operations until the automated towing, alignment and hangar are completed. The method provided by the present disclosure does not need human intervention in the whole process, and thereby reducing operation difficulty, improving transshipment efficiency, and ensuring the safety of auxiliary personnel and equipment on the ship, and having an important practical value in the fields of ships, military industry and the like.

The invention consists of an actuated box and navigation aid for automatic delivery by unmanned vehicles (UAV) or drones. It also incorporates delivery information via the web linking orders, enclosure status, package specific drone homing signals, delivery confirmations and more. This system incorporates a novel and effective means for providing a standardized and predicable area for safe landing during delivery by functionalized drones. It also secures the package from theft, vandalism, animals and the weather and provides features necessary for air-traffic management.

An external anchoring harpoon for an aircraft in order to anchor the aircraft on an anchor grid of a platform, the external anchoring harpoon comprises a frame connected to the aircraft, a harpoon head, and a deployment device for deploying the harpoon head. The deployment device comprises a cable, a movement device for moving the cable connected to the frame, the cable being connected to the harpoon head and to the movement device. The deployment device also comprises a main telescopic strut and two secondary telescopic struts so as to enable the harpoon head to be centered under the aircraft and so as to enable the harpoon head to be anchored to the anchor grid.

An embodiment device includes a clamp body having a clamp opening, an extension opening and a traverse block having an internally threaded portion, a reaction plate having a recess in a first face at a first side of the reaction plate and one or more pins disposed in the recess extending away from the first face, and further having an extension extending along a long axis of the reaction plate through the extension opening, and bearing blocks disposed on a second side of the reaction plate opposite the first side, where the traverse block is disposed between the bearing blocks. An actuator is aligned parallel to the long axis of the reaction plate and extending through each of the bearing blocks and through the traverse block, and the actuator has an eternally threaded portion engaged with the internally threaded portion of the clamp body.

Reading glasses, more specifically pince-nez glasses, for short-term, close viewing and reading. For better placement of the reading glasses on the nose, the bridge of the reading glasses is provided with knobs, of which two are located on the outside, making it comfortable to grasp and place the glasses on the nose with two fingers and third knob is located on the upper centre of the bridge. Bridge of the reading glasses is ergonomic. The measurements of the radius of bridge of the reading glasses have been developed ellipsoidal in shape, where radius r.sub.1 is 7.0 mm and r.sub.2 is 7.5 mm and the angle ? of the bridge is 36?.

A drone takeoff and landing system according to an embodiment comprises: a drone including a through-hole; and a landing pad including an extension member which can pass through the through-hole, wherein, when the extension member of the landing pad passes through the through-hole of the drone, an eddy current may occur between the through-hole and the extension member to cause magnetic braking of the drone.

An unmanned aerial vehicle docking system can include a docking arm and a docking station. The docking arm can be mounted on the UAV and include a rod with an interface element positioned on top of the rod. The interface element can have charging contacts that are attached to wires that extend down to a charging circuit on the UAV. The docking station can be located separate from the docking arm and have a guidance cone to direct the docking arm to a capture mechanism. Once the interface element is in the capture mechanism, a charging dome is then lowered down onto the top of the interface element to form a circuit between a power source at the docking station and the UAV's battery. Upon completion of the charging process, the charging dome is raised and the capture mechanism releases the interface element of the UAV.

A naval platform has a zone for the deck landing/take-off of an aircraft and an aircraft handler, to move the aircraft over the deck landing/take-off zone. The aircraft handler includes a body in the form of a bar for gripping and securing the main landing gear of the aircraft, provided with an anchoring hook mounted to slide in at least one rail, guiding the the aircraft on the deck landing/take-off zone. The hook is retractable, allowing the release of the body in the form of a gripping and securing bar from the rail, the body gripping the landing gear of the aircraft. The movement of the aircraft brings the body into position on the rail, and the hook into a position in which it faces the rail, and the hook back into an anchoring position in the rail in order to secure the aircraft.

A landing station guidance-and-security system can include an environmental cover and/or a guide-and-security bar. In some embodiments, the landing station guidance-and-security system is integrated into a parcel-receiving device. In some embodiments, the landing station guidance-and-security system is configured to attach to a parcel-receiving device. In some embodiments, the guide-and-security bar includes a precision rod. In some embodiments, a drone landing station includes: a magnetic centering mechanism configured to center a drone and/or a package; sliding dovetail doors; a plow bar; at least one roll-up door; a first storage locker; a second storage locker; and/or a solid rear door configured to block access to the second storage locker from the first storage locker when the first storage locker is being accessed by a user.

A system for handling an aircraft on a nautical vessel includes a plurality of winches each associated with a corresponding one of a plurality of electromotors and a plurality of cables associated with the plurality of winches. Each of the plurality of cables is configured to attach to an aircraft positioned on a deck of the nautical vessel. A control system is configured to receive a target aircraft hauling speed and direction and operate the winches to achieve the target speed in the selected direction while maintaining load on the aircraft to below a maximum limit and also maintaining the cables in tension.
