Abstract:
1. A turbine, comprising: a casing having a plurality of arc-shaped segments to together form a substantially circular cross-section shape of the casing, the casing having a front rim to define a front opening and a rear rim to define a rear opening, and each plurality of arc-shaped segments extending in a front-to-rear direction between the front rim and the rear rim; an affixing protrusion extending radially from an outer surface of the casing at each junction of the plurality of arc-shaped segments to affix adjacent arc-shaped segments to each other; and an annular region on the outer surface of the casing adjacent the front rim of the casing and having no affixing protrusion, the annular region having a thickness from an inside surface to the outside surface less than a thickness of the casing at the affixing protrusion from the inside surface to the outside surface, wherein the affixing protrusion extends in the front-to-rear direction on the outer surface of the casing from the rear rim of the casing to the annular region.
