Design and application of the damp shroud featuring equal strength and small loss

In accordance with the working characteristics of damping shroud for aeroengine blade,a kind of design method for blade shroud featuring streamline airfoil and equal strength has been established,and successfully applied to the structure design of the high-rotating shrouded fan blade.The result demonstrated the practicability of this method,with which the shroud structure designed has the features of light weight,smooth flow path,small loss of airflow,and high reliability etc.
