Abstract

The invention discloses a turboprop direct spraying mixed type multistage power underwater high-speed propeller and a control method. The turboprop direct spraying mixed type multistage power underwater high-speed propeller comprises a low-speed stage engine, an acceleration stage engine and a high-speed stage engine. For different concepts of operations, a water stamping high-metal content propellant engine and a high-metal content solid robot engine are combined and are assisted by a turbine power output device; and by reasonably designing a charging manner, the charging amount and the stamping water inlet amount are adjusted to meet different requirements for propelling power of a system at different cruising speeds, the limitation of a single cruising speed of a traditional underwatervehicle is broken through, and two typical movement states of conventional low-speed cruising and high-speed striking seven times of the conventional speed can be achieved 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 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...
