Description

The utility model relates to the field of shipbuilding, and more specifically to carrier ships of unmanned aerial vehicles of the aircraft type, including those with a propeller, and relates to the creation of a system for landing an unmanned aerial vehicle (UAV) on the deck of a carrier vessel.

Currently, unmanned aerial vehicles are one of the most promising reconnaissance and surveillance tools, including for monitoring the surface of the sea or certain coastal areas for various purposes, such as monitoring the movement of schools of fish, searching for shipwrecks, identifying ships, and conducting search and rescue operations, environmental monitoring, meteorological research and ice reconnaissance.

The effective use of UAVs in many respects depends on the presence of special catapults and finishers on the carrier vessel, which ensure safe takeoff and landing of the aircraft in the open sea.

It should be noted the importance of devices for landing an aircraft, since an unsuccessful landing of an UAV can entail not only its destruction, but also harm the ship and crew.

Known systems for landing UAVs (US patent No. 3980259, US No. 4311290 and US No. 4753400), representing a cable stretched between the vessel and the jib, 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. Using landing methods using known devices implies high accuracy of aircraft positioning during landing, as a result of which the operation of UAVs 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 (US patent 7219856 B2 dated May 22, 2007 - prototype), 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 depreciation of its tension in the process of stopping the geared aircraft, and a means of placing the geared 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 UAVs, and under severe meteorological conditions, when strong gusts of wind occur, emergency situations are possible during the UAV landing on the deck of the vessel.

In addition, for a UAV 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 proposed utility model is to ensure an accident-free landing of UAVs of the “aircraft” type with a propulsive propulsion device on the deck of the vessel in severe weather conditions.

To achieve this, in the known system for landing on the deck of a vessel in conditions of intense wind and sea waves, an unmanned aerial vehicle of the "airplane" type with a propeller propeller according to a utility model, the catcher of the aircraft is supplemented by cables stretched across the struts located at a pitch less than the vertical dimension of the aircraft apparatus, the number of which is determined by the value of at least the ratio of the maximum deviation of the UAV from a given flight path to its vertical overall size. At the same time, a protective nozzle is installed around the propeller propulsion device of the aircraft, on which hooks for these cables are equipped, equipped with locks. The said catcher racks, which are pivotally attached to the deck with the possibility of dropping onto the deck together with the hooked aircraft, are used as a means of placing the engaged aircraft on the deck of the vessel.

In addition, the catcher cables are fixed to the racks with the ability to adjust their pitch, and they are made of synthetic material.

At the same time, adjusting weights are hung to the ends of the catcher cables, designed to absorb the tension of the cables in the process of stopping the hooked aircraft, which are suspended from the cables through the rollers.

Along with this, the protective nozzle of the screw propeller is made in the form of longitudinally arranged strips, on which hooks for the said catcher cables are installed above and below, and the rotary racks of the cables are equipped with hydraulic cylinders.

Supplementing the UAV catcher with nearby horizontally stretched cables ensures reliable and guaranteed engagement of the UAV in conditions of intense wind for placing it on the deck of the carrier vessel.

The fastening of the catcher racks to the deck pivotally with the possibility of dropping them onto the deck of the vessel together with the hooked aircraft makes it possible to accidentally place the UAV on the deck of the carrier vessel under severe weather conditions - with intense wind and intense sea waves.

The essence of the utility model is illustrated by drawings, which shows a General view of the proposed landing system - figure 1, a fragment of the engagement of the UAV catcher - figure 2, the principle of operation of the braking UAV device - figure 3, and a fragment of the UAV setting on the deck of the carrier vessel - figure 4 .

The system for landing on the deck of a vessel in conditions of intense wind and sea waves of an unmanned aerial vehicle of the aircraft type with a propeller includes a trap 1 mounted on deck 2 (Fig. 1), a protective nozzle 3 around the propeller mover 4 of the UAV 5, made in the form longitudinally arranged strips 6 (Fig. 2), and hooks installed on it above and below 7. The catcher is a rack 8 installed on the deck, between which a number of cables 9 are pulled parallel to the deck in increments of less than the overall dimension along ticked UAV, whose number is not less than the ratio of the maximum deviation from the set of trapped UAV flight path to its dimensions in the vertical (Figures 1, 4). Catcher racks are pivotally attached to the deck with the possibility of falling onto the deck together with the hooked UAV and are equipped with hydraulic cylinders 10 for lifting and filling the racks (Figs. 1, 4). In this case, the catcher cables are made of synthetic material and fixed to the racks with the possibility of adjusting their pitch (figure 3). Adjusting weights 12 (Fig. 4) are hung to the ends of the cables through the rollers 11, which are designed to absorb the tension of the cables during the stop of the engaged UAV.

Using the proposed system, landing on the deck of a vessel in conditions of intense wind and sea waves of an unmanned aerial vehicle of the aircraft type with a propeller is carried out as follows.

Approaching the trap, the UAV is induced between the two upper cables, across the plane of their location. Entering the space between the catcher cables, the UAV hooks on the cables with special hooks located on the protective nozzle of the screw propeller. Under the action of the inertia force of the engaged UAV, the cables are pulled out, raising the adjusting weights, and thereby smoothly slowing the movement of the UAV. After stopping the UAV, the catcher together with the UAV are dumped towards the deck by turning its racks around the hinges located on the deck (not shown) with the help of hydraulic cylinders, as a result of which the UAV gradually descends to the deck (Fig. 4).

The proposed system for landing on the deck of a vessel in the conditions of intense wind and sea waves of an unmanned aerial vehicle of the aircraft type with a propulsion device allows for an accident-free landing of an UAV of an aircraft type with a screw propulsion on the deck of a vessel in severe weather conditions, which compares favorably with the prototype .
