Embodiment Construction

[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] Such as Figure 1-6 As shown, the direct-injection multi-stage power underwater high-speed thruster of the present invention mainly includes a high-speed section engine I, an acceleration section engine II and a low-speed section engine III, and the three parts are connected in sequence, and the acceleration section part is half-coated inside the low-speed engine , and the three parts are respectively fixedly connected with the aircraft shell by bolts. In the present invention, the advancing direction of the propeller is the front, and the reverse direction is the rear.

[0040] The high-speed section engine 1 mainly includes the high-speed section water inlet buffer chamber 1, the high-speed section primary water injection pipeline 2, the water stamping metal fuel 3, the high-speed section secondary water injection pipeline 4, the high-speed secti...

Abstract

The invention discloses a direct-injection type multi-stage power underwater high-speed thruster and a control method thereof, including a low-speed section engine, an acceleration section engine and a high-speed section engine, breaking through the limitation of a single speed of a traditional underwater vehicle, low speed, acceleration and The structure of the high-speed engine is interconnected, and the three stages work sequentially after starting. It can realize the two typical motion states of conventional low-speed cruise and high-speed attack seven times the conventional speed in the same voyage, and can quickly complete the high-efficiency of low-speed and high-speed two speeds. switching to ensure the stability of navigation during the switching process; the structural space layout of the propeller is reasonable, which realizes the optimal design of multi-stage propellers in the smallest space, can complete multi-task combat work under complex conditions, and can greatly improve the underwater Combat performance of weapon systems.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicle power, and in particular relates to a direct-injection multi-stage power underwater high-speed thruster and a control method. Background technique [0002] At present, the navies of various countries are focusing on the protection of maritime rights and interests, aiming at new operational needs, actively developing new equipment, and making major progress in surface ships, submarine equipment, new concepts and new technologies. Under the current situation, the role of underwater efficient offensive weapons in the modern battlefield is becoming more and more important. The killing principle of underwater weapons is to break the opponent's keel, which has strong concealment, good penetration effect and high hit rate; it can enhance the diversification of tactics and improve the attack effect. However, in the construction of underwater combat platforms, countries are generally troubled b...
