Fluid propulsor
Through a complex transmission mechanism design, the problems of cavitation and air intake in front of the propeller in ship propellers at high linear speeds have been solved, achieving the effects of increasing sailing speed, reducing frictional resistance and slip coefficient, and enhancing steering flexibility and sailing trajectory accuracy.

AI Technical Summary
Technical Problem
Existing ship propulsion systems are affected by cavitation and air intake at high linear speeds, which limits the ship's speed.
Method used
A fluid propulsion design is adopted, including a main shaft, propulsion spokes, blades, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, a first drive mechanism, and a second drive mechanism. The complex transmission mechanism enables the blades to decelerate, avoiding cavitation and air intake problems at the front of the blade.
Benefits of technology
It increases the speed of the fluid propulsion system, reduces frictional drag and slip coefficient, improves propulsion efficiency, enhances steering flexibility and navigation trajectory accuracy, and reduces manufacturing costs.

Abstract
A fluid propulsor (100), comprising: a main shaft (4), propulsor spokes (2), blades (1), a first transmission mechanism (10), a second transmission mechanism (20), third transmission mechanisms (30), a first driving mechanism (40), and a second driving mechanism (50). The first driving mechanism (40) drives the first to third transmission mechanisms (10), (20), and (30) to perform transmission, and converts a driving force from a Y direction to an X direction, then to a Z direction, and then to the X direction, such that the propulsor spokes (2) rotate with the main shaft (4), the blades (1) rotate in the opposite direction, and the reverse rotation speed of the blades (1) is half of the forward rotation speed of the propulsor spokes (2). The fluid propulsor increases the sailing speed of a main body using same.
