In previous works, the importance of considering fatigue phenomena has been analysed and a procedure for propeller blades fatigue assessment was outlined. The results obtained by applying the proce-dure allowed underlining the need of a more detailed and direct approach to propeller structural design, which could lead to different blade scantling limits. In the present work, further analyses are carried out comparing results obtained with direct calculations of fatigue effects and the requirements of some Classification Socie-ties; in order to do this, the design of a propeller with two different shaft inclinations is considered as a test case.

Abstract
In previous works, the importance of considering fatigue phenomena has been analysed and a procedure for propeller blades fatigue assessment was outlined. The results obtained by applying the proce-dure allowed underlining the need of a more detailed and direct approach to propeller structural design, which could lead to different blade scantling limits. In the present work, further analyses are carried out comparing results obtained with direct calculations of fatigue effects and the requirements of some Classification Socie-ties; in order to do this, the design of a propeller with two different shaft inclinations is considered as a test case. The analysis conducted in this work provides useful information for the propeller designer, allowing a deeper insight into the effect of propeller characteristics on its design and scantling.
