And the flatter the propeller blades are, the more consistent the forward and reverse rotating force of the propeller is, and the better the controllability of the ship is.

At present, the propeller of the small and miniature unmanned ship is made of aluminum alloy and bronze materials which are cast by plastics and nylon or precisely machined by a five-axis CNC machining center. The plastic and nylon propellers are not suitable for water areas with more waterweeds due to low cutting capacity and poor strength, while the propellers processed by a five-axis processing center are good in precision and high in strength, but have the problem that the diameter of the unmanned ship with the length of more than 2 meters is larger than 5 inches, the five-axis processing cost is too high, so that an aluminum casting mode or a blade welding mode is adopted, the precision dynamic balance performance is poor, the propellers are mostly unidirectional blades at present, the pitch is fixed, and contra-rotating paired propellers cannot be provided for the newly-generated unmanned ship industry. In addition, the propeller of the current market, whether cast or CNC (computer numerical control) machining center, has a fatal problem, namely once one blade is stranded and damaged, the propeller of the whole propeller has to be scrapped.
