Front-sucking rear-spraying power propulsion system

A front-sucking rear-spraying power propulsion system is a power propulsion system using water as a medium. The system is mainly used for overcoming the contradiction that in rivers and lakes and in the sea, the larger the propulsion power of a hull is, the larger the resistance of water is. According to the adopted technical scheme, a front-sucking rear-spraying mode is adopted, the power propulsion system generates the motion resultant force in the same direction, and water resistance generated in the heading process is converted into power. The hull serves as a background, in other words, the hull is improved, the hull sucks water from the front side, the water is pressurized through an engine water pump and then sprayed out from the rear side of the hull, and the hull can be propelledto increase the speed. The water is sucked from the front side, so that resistance is reduced; and the water is sprayed to the rear side, so that power is enhanced, the resultant force is obtained inthe front-sucking rear-spr
