This is limited by the occurrence of cavitation, vibration, noise and material strength possessed by propellers. Thus it is necessary to do a new breakthrough in designing or modifying the shape of the propeller to achieve maximum performance. One modification that can be done is to change the skew angle. Propeller B-Series is a propeller that is often used and has a fairly complete geometry data. | The effect of variation skew angle b-series propeller on performance and cavitation
