Rotating Strength of High Speed Rotor

Abstract

In this paper experiments and theoretical considerations have been made on the burst strength of a high speed rotor which is used in an axial blower or gas turbine. According to the experiments the strength of a rotor is influenced by the centrifugal force induced by blades and the ductility of material of rotor ; the strength of a rotor rises above that of a rotating disc as the centrifugal force in a ductile material increases, though it doesn't rise in a small ductile material. The influences of the centrifugal force of blade and the ductility of material on the strength of a rotor are explained by the theoretically considerations and the results agree well with the experiments.
