ABSTRACT:
A novel turbo-machine of the axial type including a rotor assembly supported within a stator housing which includes a plurality of partition wall sections positioned adjacent one another, with each pair of sections extending on opposite sides of a rotor blade attached to the rotor assembly. Each of the partition sections is formed of a pair of similarly-shaped members, with adjacent pairs of members being rotated a specific angle prior to joining all of the pairs of each other via fasteners extending therethrough, with the plurality of joined sections then attached to the stator housing in a manner which compensates for both axial and radial thermal expansion during operation.
