Description

The invention relates to systems and methods for landing an aircraft in difficult weather conditions and can be used both landing manned and unmanned aerial vehicles.

Known systems for landing aircraft, in particular unmanned aerial vehicles (see US Pat. , stretched between the ship and the boom of a crane, a kite, a parachute or some other device. The aircraft flies past the cable and, clinging to it with a special hook or lock, stops. Then the cable is selected and the apparatus with the cable descends to the deck of the vessel. The use of landing methods using known devices implies high accuracy of aircraft positioning during landing, as a result of which the operation of aircraft is very limited by meteorological conditions.

There is also known a system for landing on the deck of a ship an unmanned aerial vehicle of the aircraft type (patent US 7219856 B2, published May 22, 2007), including a catcher located on a free section of the deck, consisting of a cable horizontally stretched between two racks, attached with the possibility of its amortization tension in the process of stopping the engaged aircraft, and means for setting the engaged aircraft on the deck of the vessel. On the aircraft there are hooks reciprocal under the mentioned cable.

However, the known system does not provide reliable engagement of an unmanned aerial vehicle, and under severe meteorological conditions, when strong gusts of wind occur, emergency situations may occur during the landing of an unmanned aerial vehicle on the deck of a vessel. In addition, for an unmanned aerial vehicle with a propeller, the known system cannot be reliably used due to possible breakdown of the propeller in contact with the catcher cable.

The objective of the claimed technical solution is to provide increased accident-free and safe landing of aircraft on ferromagnetic surfaces in severe weather conditions.

The claimed system for fixing and holding the aircraft on ferromagnetic surfaces does not require high accuracy positioning of the aircraft and is applicable in difficult meteorological conditions. In particular, the claimed system can be part of rescue operations under weather conditions that provide strong disturbance in water bodies, for example, in cases where the deck of the ship is subject to significant unrest and landing an aircraft without using the claimed system presents significant difficulties.

The claimed system for fixing and holding the aircraft on ferromagnetic surfaces includes a device for fixing and holding the aircraft on ferromagnetic surfaces, an aircraft containing said device and a method of operating said device for fixing and holding the aircraft on ferromagnetic surfaces.

The presented figures are reflected:

FIG. 1 - a device for fixing and holding the aircraft on ferromagnetic surfaces;

FIG. 2 - the principle of operation of the tape at the time of separation from the landing surface.

In the FIGS. 1 and 2 reflect the following positions:

pos. 1 - spatial frame;

pos. 2 - permanent magnets;

pos. 3 - reinforcing elements made in the form of rods;

pos. 4 - node mounting the device to the landing gear of the aircraft;

pos. 5 - ferromagnetic landing surface;

pos. 6 - tape, consisting of articulated links.

So, the claimed device for fixing and holding the aircraft on ferromagnetic surfaces (see Fig. 1) includes a spatial frame (1), a tape (6), consisting of articulated links, which are permanent magnets (2) and reinforcing elements made in the form of rods (3), as well as the mount (4) of the device to the landing gear of the aircraft.

On the landing gear of the claimed aircraft, it is possible to mount the aforementioned device for fixing and holding the aircraft on ferromagnetic surfaces by means of a fixing unit. The claimed device for fixing and holding the aircraft on ferromagnetic surfaces can be both an element of the landing gear and an additional device to known structures. Moreover, the takeoff of the aircraft is carried out by sequentially detaching (disconnecting) each magnet from the landing surface (5) (Fig. 2) and reducing the influence of the magnetic field on the landing surface, and the aircraft is fixed by all magnets simultaneously. Moreover, the ability to keep the aircraft on the landing surface is provided, including after a complete shutdown of the onboard power supply, which ensures the safety of maintenance personnel.

The technical result achieved by the claimed group of technical solutions is to provide increased accident-free and safe landing of aircraft on ferromagnetic surfaces in severe weather conditions.
