THE EFFECT OF VARIATION SKEW ANGLE B-SERIES PROPELLER ON PERFORMANCE AND CAVITATION

Achieving the highest possible efficiency from a propeller is needed to minimize fuel. However, 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. Cavitation is something that must be considered because it will manifest into noise, vibration and erosion in the propeller blade. The modification of the skew angle will be analyzed using the CFD (Computational Fluid Dynamics) method of how the relationship between performance and cavitation results from the various variations that have been made
