Abstract

The invention discloses a turboprop direct injection hybrid multi-stage power underwater high-speed thruster and a control method, including a low-speed section engine, an acceleration section engine and a high-speed section engine. Aiming at different combat strategies, the water stamping high-metal-content propellant engine and the high-metal-content propellant engine are combined. Combining solid rocket motor with high metal content, supplemented by turbine power output device, through reasonable design of charging method, adjusting charge amount and punching water amount to meet the propulsion power requirements of the system at different sailing speeds, breaking through the traditional underwater navigation In the same voyage, it can realize two typical motion states of conventional low-speed cruising and high-speed attack seven times the conventional speed.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicle power, and in particular relates to a turboprop direct-injection hybrid multi-stage power underwater high-speed propeller 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 ge...
