Description

The device relates to the field of energy, namely to the power plants of submarines.

The energy compartments of submarines with hydrogen and oxygen storage in tanks between the strong and light hulls are known (see A.N.Dyadik, V.V. Zamukov, V.A. , 2006, p.129-131) and using an electrochemical generator (ECG) as a source of electrical energy. The disadvantage of a submarine with ECG is the difficulty of generating, storing and supplying hydrogen to a power plant.

The closest in technical essence is a submarine of the Agosta 90 V type with a diesel generator and a turbine unit with an electric generator as an additional energy source, a steam boiler and other auxiliary equipment. Ethanol and oxygen are used to obtain a working fluid (see E.L. Myshinsky “Submarines with Anaerobic Power Plants”, publishing house of FSUE Central Research Institute named after Academician A.N. Krylov, St. Petersburg, 2006, p.65-66). The disadvantage is that oxygen is stored in containers inside a durable case and leads to increased fire and explosion hazard.

Overcoming these shortcomings and reducing the dimensions of the energy compartments is possible if the durable building of the power plant is made with decreasing diameter at the installation site of the heat engine, and the heat engine is installed inside the sturdy case of small diameter, and the tanks for fuel and liquid oxygen should be placed in the outboard space by in the form of toroidal shells, covering the sturdy hull of the submarine in the place of reducing its diameter. In this case, the hazardous containers are moved outside the habitable space of the submarine and are separated from each other by flowing seawater through the inlet and outlet openings in a light hull, which significantly increases the safety of its operation.

A diagram of such an installation is shown in Figure 1. It consists of a solid casing 1, a light casing 2, a toroidal tank for storing an oxidizer 3, a toroidal tank for storing fuel 4, a heat engine 5, a fuel preparation system 6, and an oxidizer preparation system 7, and in the light casing 2 there are openings for entering and exiting outboard water 8.

Installation works as follows. The oxidizing agent from the toroidal tank for storing the oxidizer 3 and the fuel from the toroidal tank for storing the fuel 4 are fed through the fuel preparation system 6 and the oxidizer preparation system 7 to the heat engine 5, where it burns and does useful work, setting the submarine in motion. Capacities of a toroidal shape for storing oxidizer 3 and fuel 4, while in the niche of the solid hull 1, are closed by a light hull 2, which ensures the absence of additional hydraulic resistance to the movement of the submarine. The external hydrostatic pressure of water during submersion of a submarine is perceived by the walls of tanks of a toroidal shape for storing oxidizer 3 and fuel 4. Moreover, the pressure inside these tanks during immersion is comparable to external pressure. Thus, the tension in the walls decreases, the operation of the power plant becomes more safe both from the point of view of the strength of the tanks and from the point of view of finding them outside the inhabited compartments of the submarine. In the event of leakage of fuel or an oxidizing agent into the space between the strong body 1 and the light body 2, they are removed by the flowing sea water through the openings for the entrance and exit of sea water 8 existing in the light body.

The proposed technical solution can significantly improve the safety of operation of an air-independent power plant for a submarine with a variable cross section of a sturdy hull and reduce its dimensions.
