Direct injection type multi-stage power underwater high-speed thruster and control method

Abstract

The invention discloses a direct injection type multi-stage power underwater high-speed thruster and a control method. The direct injection type multi-stage power underwater high-speed thruster comprises a low-speed section engine, an acceleration section engine and a high-speed section engine. The limitation of the single navigation speed of a traditional underwater navigation vehicle is broken through, the low-speed section engine, the acceleration section engine and the high-speed section engine structurally communicate with each other, three sections work in sequence after the thruster isstarted, and two typical motion states including the conventional low-speed cruise and the high-speed attack at the speed which is seven times the conventional speed can be achieved in the same voyage; and the efficient switching of the low navigation speed and the high navigation speed can be rapidly accomplished, and the stability of navigation in the switching process is guaranteed. The structural space arrangement of the thruster is reasonable, the optimized design of the multi-stage thruster in the minimum space is achieved, the multi-task fighting work under the complex condition can beaccomplished, and the fighting performance of an underwater weapon system can be greatly improved.

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...
