Construction of a blade beam finite element as a component of the blade disk rotary-symmetrical system

Abstract


The blade wave finite element has been developed. A FORTRAN code program has been developed for the modal analysis of rotating nonuniform heated blades of gas turbine engines. Natural modes of oscillation of two compressor blades have been analysed.
