摘要
Three dimensional finite element method is applied to stress analysis of the original and the redesigned propeller blade taking the loads,such as centrifugal and dynamical loads.In respect of stress distribution,the airfoil of the redesigned propeller blade is more reasonable.Its stress distribution approaches to isostrength,and safety coefficient also meets the given specification.Therefore,the redesigned propeller blade is an quite advanced design.
