Abstract
Compressed Air Supply: The shaftless propeller compresses a large amount of air to a high-pressure state through a compressor. This compressor can be driven by external energy sources such as electricity or fuel.
Combustion Chamber: The compressed air is introduced into a combustion chamber, where it mixes with fuel and ignites, producing high-temperature and high-pressure combustion gases.
Thrust Generation from Nozzle: The combustion gases are ejected into a specially designed nozzle. The design of the nozzle allows the gases to be expelled at high speed, generating thrust through Newton's third law. The shape and size of the nozzle affect the speed and angle of the ejected gases, thereby influencing the magnitude and direction of the thrust.
Accumulated Thrust: The shaftless propeller can accumulate thrust by simultaneously ejecting from multiple nozzles. The coordinated operation between multiple nozzles makes the thrust smoother and more controllable.
Advantages and Applications of Shaftless Propellers:
Lightweight and High Efficiency: Shaftless propulsion technology eliminates the shaft in traditional propulsion systems by directly integrating the motor inside the propeller, reducing energy transmission resistance and vibration, thus improving the efficiency and reliability of the system.
Low Noise: By eliminating the shaft in traditional propulsion systems, shaftless propellers produce less noise during operation.
Flexible Propulsion Methods: By controlling the rotation direction and speed of the motor, various propulsion methods can be achieved, such as moving forward, backward, and turning, increasing the maneuverability and agility of ships or aircraft.
Application of Shaftless Propellers in Nuclear Submarines:
The application of shaftless propulsion technology in nuclear submarines makes the propulsion system more compact, lightweight, and efficient. This technology enhances the stealth and maneuverability of submarines, giving them a greater advantage in maritime operations.
