Calculation of natural frequencies and effective elastic properties of the axial compressor rotor blade

Abstract

The results of the numerical calculations of the natural frequencies of the composite rotor blade axial compressor of aircraft gas turbine engine. Shows the way of solving of а unit cell problem arising in the application of asymptotic homogenization method to elastic deformation of regular composite structures. Components of the effective stiffness matrix of the composite blade obtained by asymptotic homogenization.
