2049585 SHAFT PROPELLER For HITACHI ZX200 6BG1T

The working principle of shaft propeller is that a large amount of air or water is pushed backward by the rotation of blades in air or water, thus generating forward propulsion. The component of aerodynamic force on the blade in the forward direction constitutes a pulling force, and the component in the rotating surface forms a torque to prevent the propeller from rotating, which is balanced by the torque of the engine. The efficiency of shaft propeller is expressed by the ratio of output power to input power, and it is usually high in the range of flight speed of 200-700 km/h.

Shaft propeller is widely used, not only for the propulsion of aircraft and ships, but also plays an important role in various means of transportation. With the development of material science and manufacturing technology, the efficiency and performance of shaft propellers have been continuously improved to meet the needs of different vehicles.
