Knowledge — propeller

Ⅰ. The design of underwater thruster propeller has the following aspects to consider

1、Thrust demand: it is necessary to determine the propeller diameter, torsion, number of blades and other parameters by calculating the thrust required by the thruster.

2, hydrodynamic performance: need to consider the propeller blade shape, cross-sectional shape, pitch and other parameters to achieve the best hydrodynamic performance.

3, noise and vibration: the need to optimize the structure of the propeller to reduce noise and vibration, improve the reliability and service life of the propeller.

4、Materials and manufacturing: Suitable materials and manufacturing processes need to be selected to ensure the strength, stiffness and corrosion resistance of the propeller.
