Claim:
1. A turbine seal plate for an air cycle machine, the turbine seal plate comprising: an inner rim comprising a labyrinth seal land that defines a central bore having a labyrinth seal diameter; a housing coupling ring arranged radially outward of the inner rim; a housing pilot extending axially from the housing coupling ring and substantially parallel to the labyrinth seal land with respect to a radially inner portion of the housing pilot, wherein the housing pilot comprises a turbine housing pilot defined by a first radially outer portion of the housing pilot having a turbine housing pilot diameter, and the housing pilot further comprises a compressor housing pilot defined by a second radially outer portion of the housing pilot having a compressor housing pilot diameter, wherein the housing pilot has a housing pilot thickness, a ratio of the housing pilot thickness to the labyrinth seal diameter is between 0.08 and 0.14, a ratio of the housing pilot thickness to the turbine housing pilot diameter is between 0.0101 and 0.0177, and a ratio of the housing pilot thickness to the compressor housing pilot diameter is between 0.0102 and 0.0178; and a frusto-conical body extending between the radially inner portion of the housing pilot and the inner rim.
