Built-in multistage-thrust underwater power system and control method thereof

Abstract

The invention provides a built-in multistage-thrust underwater power system and a control method thereof. A solid rocket engine and a solid water ramjet engine are integrated, and the multistage-thrust underwater power system is designed. At a boosting stage, the traditional solid rocket engine is adopted for propelling, underwater high-thrust acceleration of a navigation body can be achieved, andthe acceleration time is shortened; and at a cruising stage, the solid water ramjet engine is adopted for propelling, seawater existing in the environment is adopted as an oxidizing agent, the specific impulse of the engine is increased, and the endurance time of the engine is prolonged. An afterburning chamber and a spray pipe of the solid water ramjet engine are improved, the afterburning chamber and the spray pipe of the water ramjet engine are also used by the solid rocket engine, 'one chamber with two uses' and 'one pipe with two uses' are achieved, the internal space of the navigation body is greatly saved, and the overall property of the navigation body is improved.

Description

technical field [0001] The invention relates to a built-in multi-stage thrust underwater power system and a control method thereof, belonging to the technical field of underwater navigation power. Background technique [0002] In the 21st century, with the development of various underwater vehicles, the speed requirements of underwater vehicles are getting higher and higher, and the underwater navigation speed that traditional propulsion systems can provide cannot meet the needs of new submarine missions. Therefore, it is of great significance to study new high-speed underwater power systems. [0003] Traditional underwater power systems are generally propeller propulsion and solid rocket motor propulsion. Due to the slow propulsion speed of the propeller and the long-term storage of batteries that provide energy, it is difficult to meet the requirements of underwater high-speed navigation of the vehicle. Solid rocket motors have the advantages of large thrust, simple stru...
