METHODS OF GASODYNAMICAL DESIGN, IMPROVEMENT OF MEMBERS OF RUNNING PART OF TURBINES OF AIRCRAFT HIGH-TEMPERATURE ENGINES

There the reliable design methods of main gasodynamical characteristics of blade lattices as well as of influences of radial clearance and of discharge of cooling air into the running part on the turbine operation, the new design principles which are classified as the choice of operating conditions and of cooling systems of blades, as the control over the radial clearance, as the axial off-loading of rotor and as the putting shroud on blades, the original contouring method and the new optimization manners of blade rims have been developed. The formulated designs of experimental and production-type engines. The presented methods and the recommendations to improve the running parts have been brought in the practice of many Design Offices. The obtained results allow to create the effective turbines, to rise their economical operation and the reliability, to decrease the periods of research works. The application fields are the heat engines of aircraft and of surface transport, the marine and fixed turbine installationsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
