A forward-leaning ultra-high-speed cruising and rescue speedboat with an angle of attack

Abstract

The invention discloses a super-high-speed cruising and rescue speedboat with an angle of attack forward. The speedboat includes a hull, a waterway and a propulsion pump. The propulsion pump includes seat ring, axial flow vane, magnetic bearing, stator and rotor. There is an annular groove inside the water channel, and the seat ring is installed in the groove through a magnetic bearing. The axis of the seat ring coincides with the axis of the water channel. The inner ring of the seat ring is installed with several Axial flow blades distributed uniformly around the circumference. The axial flow blades form a fan shape with the axis of the seat ring and extend toward the axis of the seat ring. All the axial flow blades extend to the axis of the seat ring and are spot welded together. The rotor is fixedly installed on the outer ring of the seat ring. The stator is fixed on the inner wall of the water channel and faces the rotor, and the magnetic bearings are respectively installed in pairs on the seat ring and the inner wall of the water channel, and the magnetic bearings are arranged along the axial and radial directions of the axis of the water channel.

Description

Technical field [0001] The present invention relates to the field of speedboats, specifically a waterward angle forward-leaning ultra-high-speed cruise rescue speedboat. Background [0002] A speedboat is a surface boat that travels fast and is often used for surface emergency command and rescue. [0003] High-speed speed boat, when driving, the water in front of the water will be subject to greater resistance, and the bow is raised, driving in a large wave environment is unstable; moreover, the structure of the propeller rear, due to the bottom of the hull squeezing the water, so the water that enters the propeller is gathered from both sides into the area between the propeller and the stern, and then pumped by the propeller, when driving fast, the disturbance is large, the water flow is turbulent, and the operating condition of the propeller is very poor, easy to damage, and the operation condition is not good. [0004] The traditional steering is done through the steering rud...

AI Technical Summary

Problems solved by technology

[0003] When a speedboat traveling at high speed breaks through the water in front of it, it will experience greater resistance, and the bow is raised, making it unstable in a large wave environment; moreover, the structure with the propeller behind, because the bottom of the hull squeezes out the water, Therefore, the water entering the propeller is gathered from both sides into the area between the propeller and the stern, and then pumped by the propeller. When driving fast, the disturbance is large and the water flow is turbulent. The operating condition of the propeller is very poor and it is easy to be damaged. , running poorly

[0004] Traditional steering is accomplished through the steering rudder at the tail. When driving at high speed, if the position of the steering rudder is suddenly changed, it is prone to drastic changes in force, affecting driving stability, and even capsizing
