Embodiment Construction

[0044] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0045] Such as figure 1 , 2 , 6 and 7, a kind of semi-enveloped multi-stage power underwater high-speed thruster of the present invention mainly comprises three parts of the high-speed section engine, the acceleration section engine and the low-speed section engine connected in sequence, and the three parts are respectively connected by bolts and The hulls of the aircraft are connected, and the part of the acceleration section is half-covered inside the low-speed combustion chamber. In the present invention, the advancing direction of the propeller is the front, and the reverse direction is the rear.

[0046] The high-speed section engine mainly includes the high-speed section water inlet buffer chamber 1, the high-speed section primary water injection pipeline 2, the end-fired water stamping metal fuel 3, the high-speed section secondary water injection...

Abstract

The invention discloses a semi-covered multi-stage power underwater high-speed thruster and a control method. The three engines are structurally connected and work sequentially after starting. The space layout is reasonable, and the multi-stage thruster in the smallest space is realized. The optimal design, aiming at different combat strategies, breaks through the limitation of single speed of traditional underwater vehicles, combines water ram high metal content propellant engine with high metal content solid rocket motor, supplemented by turbine power output device, through reasonable By designing the charging method, adjusting the amount of charge and the amount of punching water, two typical motion states of conventional low-speed cruising and high-speed strike at seven times the conventional speed can be realized in the same voyage.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicle power, and in particular relates to a semi-covered 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 by th...
