Vector water-jet propeller and vector water-jet propulsion method

Abstract

The invention discloses a vector water jet propeller device and a vector water jet propulsion method, belongs to the technical field of water propulsion of ships and amphibious vehicles, and solves the problem that the existing water jet propulsion ship and amphibious vehicle cannot effectively control the posture of a vehicle body or a ship body. The vector water jet propeller mainly comprises awater inlet shell, a water outlet shell, a propeller support, a water jet propeller inner container and an oil cylinder assembly arranged on the propeller support. The spherical propeller inner container can rotate in the shell, the two ball supports which are perpendicular to each other are fixedly installed on the inner container, the water jet propeller inner container is pushed to rotate in the shell by controlling stretching and retracting of a piston rod of the oil cylinder assembly, the left-right angle and the pitching angle of a water spraying pipe on the inner container are adjusted,and the water spraying angle of the vector water jet propeller is controlled. Vector propelling force in different directions can be obtained by changing the angle of tail water jet flow, then the posture can be adjusted according to environmental disturbance and waves, and the seakeeping performance and navigation stability of amphibious vehicles or ships are improved.

Description

technical field [0001] The invention relates to the technical field of water jet propulsion for ships and amphibious vehicles, in particular to a vector water jet propulsion device and a vector water jet propulsion method. Background technique [0002] At present, there are two main forms of ship propulsion and amphibious vehicle water drive: traditional propeller propulsion and water jet propulsion technology developed in recent years. Waterjet propulsion ships have certain advantages over propeller-driven ships in terms of propulsion efficiency, maneuverability and maneuverability, and have been widely used in various high-performance ships and military amphibious vehicles. [0003] At present, the research on water-jet propulsion ships mainly focuses on propeller efficiency and course speed control, etc. There are few studies on the navigation stability control of ships and car bodies, and some of them focus on double-pump or multi-pump water-jet propulsion ships. The ve...
