| Abstract: | Based on the relation between lift coefficient CL and geometry of blade, this paper deduces a pitch correction method caused by the change in thickness of blade and geometry. The method can be applied to some special case such as ice stengthening propeller design, where conventional pitch correction method is invalid. The model experimental results show that the method is reliable for the given application case. |
