Description

The invention relates to the field of shipbuilding, mainly to the equipment of helipads, which are placed on the ship deck.

Shipbuilders are faced with the task of rational use of space on a ship. On warships and on some types of civilian vessels, helipads are arranged to accommodate a helicopter. Appropriate facilities are needed to service the helicopter, including shelter for the car and technical personnel in bad weather. Various layout solutions are used for installing a helicopter hangar on a ship.

Known warship according to the patent for utility model No. 118289, publ. 07/20/2012. A helipad and a hangar for a helicopter are equipped on the ship. Block-modular constructions of power and power plants, weapons, hangars, aircraft, domestic and office premises are located below deck.

The utility model solves the problem of creating a rational layout of the ship, providing maximum use of the deck for takeoff and landing of aircraft. The stealth and greater security of the ship are also provided with an improvement in its seaworthiness.

This technical solution has certain advantages, but it is possible to improve the design.

Also known is a ship with a displacement of a class of frigate according to the patent for utility model No. 644588, publ. 07/10/2007. The ship has a landing pad and a hangar, which are necessary for basing and using, including in combat conditions, at least one helicopter, as well as means of aviation technical support for flights and keeping the helicopter on deck.

The utility model solves the problem of improving the economy, durability and survivability of the ship while ensuring high driving and combat qualities. In this case, new solutions can be found to improve the parameters of the vessel.

The task of the invention is to expand the functionality of equipment located on the deck of the vessel in the area of the helipad.

The technical result from the solution of the problem is to increase the efficiency of the use of the deck area and improve the comfort of maintenance and operation of the helicopter.

The technical result is achieved by a hangar for a deck helicopter located on the deck of the vessel. The hangar contains a hull and means of attachment to the deck of the vessel,

The new one is that the hangar is made movable, fixed on the helipad after landing the helicopter and fixed on the deck outside the platform above the area with naval armament before the helicopter takes off. The hangar can be installed on rails fixed in the deck.

The drawings show a schematic image of a hangar with a helipad located on the aft deck:

Figure 1 is a side view of the ship when the hangar is outside the helipad;

figure 2 is a side view of the ship when the hangar is located above the helipad;

figure 3 is a top view of the ship when the hangar is outside the helipad;

4 is a top view of the ship when the hangar is above the helipad.

In the initial position, the helipad 4 is free from shelter (Fig.1, 3). Hangar 1 is shifted towards the bow of the vessel. At this time, module 3 is under the hangar with the armament of the ship, for example, with the installation of a vertical launch of missiles. If the vessel is for other purposes, in particular research, then in module 3 there may be equipment necessary to perform the functions of the vessel.

After landing of helicopter 2, the hangar is shifted towards the stern, and the helicopter is in cover until the next take-off (Figs. 2, 4). On the walls of the hangar, wheels 5 are fixed, rolling on rails 6, fixed below the deck level.

In the prototype of patent No. 644588 on the deck of the ship there is a helipad and next to it is a stationary hangar for a helicopter. Obviously, after landing on the site, the helicopter is rolled into the hangar for storage and maintenance, and before take-off it is rolled out onto the open deck.

Unlike the prototype, the inventive hangar is moved to the right place with the help of simple manipulations.

In one position, the hangar is fixed and located outside the helipad. At the same time, it covers the module with ship equipment and does not require a special deck area for its placement. A helipad is free for takeoff and landing of a helicopter.

In another position, being moved and fixed on the helipad, when there is a helicopter on it, it performs the functions of the hangar for the helicopter itself, providing storage and maintenance of the aircraft.

The design of the hangar provides fixing means for securely fastening in the selected place. The end walls can be made swing on hinges or movable to the sides or in the vertical direction so as not to impede the longitudinal movement of the hangar along the guides.

Using the inventive hangar gives the helipad universal properties. When the hangar is shifted away from the site, it is a heliport, i.e. open and serves for take-off and landing of the helicopter. In another position, when the hangar completely covers the platform with the helicopter standing on it, it becomes part of the room, i.e. represents the floor of the hangar. When installing a helicopter in the hangar, it is not the helicopter that is moved, as is the case when using the prototype, but the housing of the hangar is moved, covering the helicopter in place.

A hangar with a telescoping folding structure is also known (see "Project 956" Sarych "- http://commons.wikimedia.org/wiki/File:A_Russian_Helix_KA-27.jpg?uselang=en).

The main disadvantage of this project is that the hangar when folded occupies a useful deck area without performing useful functions in the absence of a helicopter.

Thus, the achievement of the technical result is confirmed - increasing the efficiency of the use of the deck area and improving the comfort during maintenance and operation of the helicopter.
