A separate multi-stage thrust underwater power system and its control method

Abstract

The invention provides a separate multi-stage thrust underwater power system and a control method thereof. A water ramjet is nested in an annular hollow solid rocket motor, and a separate multi-stage thrust underwater power system is designed. . The boost section is powered by a solid rocket motor, which increases the thrust and shortens the acceleration time. The cruising segment is propelled by a solid water ramjet, which improves the specific impulse and cruising time of the engine. The invention improves the solid rocket motor of the booster section, the booster section engine is designed into a ring-shaped hollow shape, which is nested in the supplementary combustion chamber of the water ramjet engine, and the uniform annular shape can ensure the navigation body when the booster section engine is disengaged. The force is uniform, which greatly improves the reliability of the engine.

Description

technical field [0001] The invention relates to a separate multi-stage thrust underwater power system and a control method thereof, belonging to the technical field of underwater navigation power. Background technique [0002] Due to its excellent performance of autonomous navigation in water, underwater vehicles are often used to carry out various activities and tasks underwater. Most traditional underwater vehicles use propeller propulsion, which has the disadvantages of slow sailing speed and short voyage. At the same time, there are many difficulties in long-term storage of batteries that provide energy for propellers. [0003] In view of the shortcomings of traditional propeller propulsion, countries around the world have begun to adopt jet propulsion systems. The common jet power system is divided into two stages of booster section and cruising section. The cruising section uses a metal-fueled water ramjet, and the thrust of the booster section is provided by multiple...

Problems solved by technology

[0004] In view of the low speed of the vehicle propelled by the traditional underwater power system, and the defect that the traditional dynamic jet power system is likely to cause uneven force on the vehicle during the separation stage of the booster engine, the purpose of the present invention is to provide a separate multi- On the one hand, the underwater power system with super-thrust and its control method can meet the working requirements of high-thrust acceleration and long-term continuous high-speed navigation; The problem of uneven force, greatly improving the navigation ability of underwater vehicles
