Abstract: An environmental control system includes a rotary machine, a first bypass duct, and a first check valve in the first bypass duct. The rotary machine includes a compressor section and a first turbine section. Each section of the rotary machine includes an inlet, an outlet, a duct extending between the inlet and the outlet, and an impeller in the duct. The rotary machine also includes a tie rod mechanically connecting the compressor impeller and the first turbine impeller. The first bypass duct is between the compressor section and the first turbine inlet. The check valve opens the first bypass duct when an air pressure in the compressor inlet is higher than an air pressure in the first turbine inlet.

Abstract: A method of repairing a compressor outlet housing includes the steps of obtaining a damaged compressor outlet housing having a radially outer volute, a radially inwardly extending finger extending to an axially extending ledge, a radially inwardly extending web extending radially inwardly from the ledge, and a radially inner bearing support defining a bore. The method identifies a damaged section within at least one of the bearing support, the web, and the ledge, and removes at least the bearing support and the web to leave a remaining part. The method then inserts an insert having at least a replacement bearing support and a replacement web into the remaining part after the removal step. The method then welds the insert to the remaining part to provide a repaired compressor housing. A method of replacing a compressor outlet housing and a replacement compressor outlet housing are also disclosed.

Abstract: A first stage turbine nozzle includes a first stage hub portion extending axially along a central axis, a first stage disk portion attached to the first stage hub portion and centered on the central axis, and a plurality of first stage vanes positioned radially around and attached to the first stage disk portion. Each vane extends a vane height H away from the first stage disk portion and each vane has a first end positioned at a diameter D away from the central axis. The first stage turbine nozzle also includes a plurality of first stage throats defined between radially adjacent first stage vanes. Each first stage throat has a throat width W between radially adjacent first stage vanes. The first stage turbine nozzle also includes a coating on a sidewall of each first stage vane, wherein a surface roughness of the sidewall is between 125 and 200 microinches Ra.

Abstract: A repaired turbine housing for use in an air cycle machine including a journal bearing bore having an inlet, an outlet, and an inner diameter of about 2.580±0.001 inches (6.553±0.003 centimeters). The repaired turbine housing including a cylindrical insert secured within the journal bearing bore. The cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The cylindrical insert being inserted into the inlet of the journal bearing bore up to the step. The step has an outer diameter greater than the outer diameter of the cylindrical insert. The inner surface of the cylindrical insert includes at least one selected inner diameter.

Abstract: A turbine seal plate includes an inner rim with a labyrinth seal land that defines a central bore having a labyrinth seal diameter. The turbine seal plate also includes a housing coupling ring arranged radially outward of the inner rim. A housing pilot extends 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. The housing pilot has a housing pilot thickness, and a ratio of the housing pilot thickness to the labyrinth seal diameter is between 0.08 and 0.14. A frusto-conical body extends between the radially inner portion of the housing pilot and the inner rim of the turbine seal plate.
