Abstract

The algorithm and numerical method of calculation of aeroelastic behaviour and energy losses in a turbine step in a three-dimensional stream of viscid gas on the basis of the decision of the connected problem of non-stationary aerodynamics and elastic fluctuations of blades taking into account leakings in a radial clearance is presented.
