Разработка модели учёта аэродинамической связанности и демпфирования при колебаниях лопаток

Abstract

The shows the development of a calculation model to account the aerodynamic damping and connectedness of blade forced vibrations. Has been solved the problem of aeroelasticity in the case of plane blades vibrations. Has been proposed a method for replacing the aeroelastic problem by the gas-dynamic calculation of an equivalent mechanical system. Main laws of aeroelastic vibrations are identified.
