Tube-type vortex reducer

摘要

A tube-type vortex reducer for the conduction of cooling air in a compressor ( 1 ) of a gas turbine, having radial secondary air tubes ( 2 ) arranged in a disk interspace ( 5 ) and attached to a compressor disk ( 3 ) at their radially outward end sections ( 33 ). Radially inward sections ( 30 ) of the secondary air tubes ( 2 ) are located fittingly and radially outward in recesses ( 31 ) of locating pads ( 32 ) of a compressor disk ( 3 ), and the radially outward sections ( 33 ) of the secondary air tubes ( 2 ) are carried radially shiftable in recesses ( 34 ) of locating arms ( 35 ) of the compressor disk ( 3 ) and are secured against radially inward movement by locking elements ( 36 ).
