Abstract

The invention discloses a concealed multi-stage power underwater propeller with a secondary mixing chamber and a control method, including a low-speed engine, an acceleration engine and a high-speed engine. The layout is reasonable, realizing the optimal design of the multi-stage propeller in the smallest space; for different combat strategies, the water ram high metal content propellant engine is combined with the traditional grain engine, supplemented by the turbine power output device, through reasonable design The charging method, adjusting the charging amount and punching water volume meet the propulsion power requirements of the system at different sailing speeds, breaking through the single speed limit of traditional underwater vehicles, and can achieve conventional low-speed cruise and seven times the conventional speed in the same voyage. The high speed of speed strikes two typical sports states.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicle power, and in particular relates to a hidden multi-stage power underwater propeller with a secondary mixing chamber 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 generall...
