Centrifugal type compressor composite blade structure influence on its stress-strain state

Abstract

The theoretical bases of calculation of stressed and strained states of centrifugal type compressor composite blades are presented in the article. The main external force factors acting on the centrifugal compressor blade are determined. The results of a computational experiment on revealing the influence of the blade structure (angles of layers stacking) on the stresses in the plies and the deformed state of the blade are presented. The simulation was performed in ANSYS software using the ANSYS Composite Prepost module. Material of the blade is a layered fibrous carbon plastic based on a carbon tape and a polyimide matrix. The results of the simulation made it possible to determine the structure of the composite compressor blade, which most fully corresponds to the external field of mechanical and temperature loads.
