Description

The invention relates to ship systems of a submarine, in particular to a fuel system.

Known ship fuel system (see S.N. Prasolov, MB Amitin. The device of submarines. M: Military publishing house of the Moscow region, 1973, pp. 139-146, 267, Fig. 53, 54, 56, 111), which is intended for the reception, storage and supply of diesel fuel to main diesels, diesel generators and diesel compressors, as well as the transfer of fuel to other ships or to the base. This fuel system includes external fuel tanks, a device for sludge and fuel supply to a diesel engine (fuel tank), located under the ceiling of the diesel compartment with a sludge drain pipe, a supply and discharge pipe, and a fuel supply pipe for diesel.

External fuel tanks hold 85-97% of the total fuel supply. They are traditionally located in the space between the strong and light hulls of the submarine.

The specified fuel system is adopted as a prototype.

The disadvantage of the fuel system adopted for the prototype is the following.

Modern submarine development trends suggest a transition to single-hull architecture, a comprehensive reduction in the volume of the double-hull space, as a result, the placement of fuel-ballast tanks is difficult, and the placement of fuel tanks inside a solid hull increases the normal displacement of the submarine. If the fuel tanks located in the inter-side space are used as ballast tanks as fuel is consumed, then the internal fuel tanks become useless when the fuel is used up.

The aim of the invention is to reduce the volume of the fuel system when placing it on a submarine.

This goal is achieved by the fact that the fuel system of the submarine is equipped with additional fuel tanks, made in the form of, for example, bodies of revolution and equipped with pipelines with replacement valves. Additional tanks are installed flush-mounted, outside the submarine’s hull and are interconnected by a wing-shaped fairing, consisting of two side sections, while the fairing in the middle part is made in the form of a substructure of the submarine, and the pipelines of additional tanks are placed inside the wing-shaped fairing, and the side sections of the fairing are connected between itself and with the hull of the submarine by quick disconnect connections.

The invention is illustrated in the drawing, where in FIG. 1 shows a submarine fuel system.

The fuel system of submarine 1 includes external fuel tanks 2 in the form of, for example, bodies of revolution mounted outside the hull of submarine 1 and connected by a wing-shaped streamlined fairing 3 mounted on the superstructure 4 of submarine 1. Fuel tanks 2 are provided with pipelines with valves 5 for receiving fuel and valves 6 for replacing fuel with seawater. The fuel tanks are equipped with a fuel supply device, including pipelines 7 with valves 8, to the supply tank 9. The fuel tank cowl mounted on the superstructure 4 is equipped with a quick-disconnect connection 10. The valves 6, 8 are remote-controlled.

The external fuel tanks 2 are installed on the superstructure 4 of the submarine 1 before going out to sea and are filled with fuel through valves 5. Fuel is pumped through pipelines 7 with valves 8 to a consumable tank 9, from where it enters the diesels. As fuel is used in tanks 2, it is replaced with seawater through valve 6. After all fuel is used in tanks 2, fuel tanks 2 are discharged using a quick coupler 10. The shape of the wing-shaped fairing 3 is selected to minimize the resistance to movement of the submarine 1.

Thus, the presented description and drawing allow us to conclude that the claimed fuel system of the submarine has novelty, differing from the prototype in that it is equipped with additional fuel tanks made in the form, for example, of rotation bodies and equipped with pipelines with replacement valves, with additional the tanks are installed flush-mounted, outside the submarine’s hull and are interconnected by a wing-shaped fairing, consisting of two side sections, with the fairing in the middle part of the nen shaped superstructure submarine pipelines and additional tanks located inside wing-shaped fairing, the fairing side sections are interconnected with the housing and a submarine quick couplings.
