Embodiment Construction

[0032] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0033] At present, underwater vehicles use solid gunpowder to burn high-temperature gas. Solid gunpowder has a high energy density, which can reduce the space occupied by the vehicle. The design of gas control valve parts and the heat insulation design of equipment have brought great difficulties. Aiming at the disadvantage of high temperature of high-temperature gas, the present invention proposes a method of introducing external water to mix with high-temperature gas to achieve the purpose of reducing the temperature of gas.

[0034] Specifically, the embodiment of the present invention pro...

Abstract

The invention relates to a high-temperature gas source water-mixing cooling method suitable for an underwater high-speed vehicle, belongs to the technical field of fuel gas cooling of underwater vehicles, and solves the problem that the fuel gas cannot be cooled reasonably through an existing method. According to the water-mixing cooling method, external water is introduced and is mixed with the high-temperature fuel gas, so that the purpose of reducing the fuel gas temperature is achieved; the high-temperature fuel gas can be continuously cooled, the structure and the equipment heat release and heat insulation design difficulty are reduced; and the external water is introduced to cool the high-temperature fuel gas, generated water vapor can be taken as a part of gas source, the amount of solid powder can be reduced, and the overall performance of the underwater vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of gas cooling for underwater vehicles, in particular to a high-temperature gas source water mixing cooling method suitable for underwater high-speed vehicles. Background technique [0002] Underwater high-speed vehicles have gas supply requirements, and their gas sources and gas control devices need to be built inside the vehicle. If the gas source is in the form of high-pressure gas cylinders, the energy density of the gas is low, and it takes up a lot of space inside the vehicle, which will greatly reduce the underwater aircraft performance. At present, the method of burning solid propellant to generate high-temperature gas is often used. The high energy density of solid propellant can reduce the space occupied by the aircraft, but the high temperature of the gas (1000-2000 degrees Celsius) will affect the aircraft structure, cable layout, and gas control. The design of valve parts and the heat insulatio...
