The axial turbine for the axial turbine null gas turbine for the gas turbine which has the idle which is stipulated

摘要

This invention has, the axial turbine for the gas turbine in regard to (1), the respective leading edge (3) and the independent blade point (13) the rotor blade which it possesses the rotor blade cascade and the rotor blade cascade which are formed from (2) the surrounding and the annular spatial inside (12) adjoins to the blade point and the annular spatial wall which it tries to be able to form the gap of radial with the blade point and the annular spatial inside (11) with has the annular spatial wall which is arranged. As for this invention, the blade point, the territory of the blade point where maximum cylinder pressure load is imposed when operating of the axial turbine is arranged in the leading edge and the rotor blade in the territory of that leading edge has the radial bulging section (16), as the radial bulging section the marginal radial concave section which operates mutually (15) it possesses the annular spatial wall in the annular spatial inside, the gap width smallest section sees in the territory of the leading edge and provided in main percolation direction of the axial turbine, it features that aeromechanics it is constituted.
