Bypass housing in air cycle machine
A turbine bypass housing is provided. The housing includes a body having an inlet end and an outlet end and defining an interior, an outlet flange is configured at the outlet end and has a rim diameter, and an inlet flange is configured at the inlet end and has a flange thickness. An interior wall of the body has a first fillet radius proximal to the inlet flange and at least one boss is configured on an exterior of the body, wherein the boss defines a boss aperture therein, the boss aperture extending from an exterior of the body to the interior of the body. The flange thickness is 0.200±0.005 inches (0.508±0.013 cm).
