  • Patent number: 9976447
    Abstract: A turbine inlet housing has a main housing body extending about a central axis. An inlet duct delivers air into a cavity within the main housing body. Bolt hole bosses are formed on a downstream face of the inlet housing to receive bolts to secure an outlet housing to the inlet housing. A plurality of the bosses have a ramped surface which extends radially outwardly for a greater extent than a second plurality of bosses. The plurality of ramped bosses extend between the downstream face and the duct. The ramped bosses have a forward boss portion, and a ramped surface at an angle of between 50 and 54 degrees extending from an upstream end of the forward boss portion. A curved surface curves from an upstream end of the ramped surface to merge into the duct. A turbine stage and air cycle machine are also disclosed and claimed.
