Abstract: A turbine inlet supplies compressed air to drive a turbine impeller. There is a compressor impeller and a compressor inlet connected to supply air to be compressed to the compressor impeller. The compressor impeller delivers air to a compressor outlet. The compressor outlet is connected to the turbine inlet. A turbine outlet is connected to a first connection connected to an aircraft. The turbine impeller is connected to the compressor impeller by a drive shaft including a radially outwardly extending thrust disk, and thrust bearings provided on each side of the thrust disk. A cooling air inlet is connected to pass air along the thrust bearings, then radially inwardly and then axially along the shaft. The cooling air is directed to a cooling air outlet. The cooling air outlet is connected to a second connection maintained separate from the first connection. An environmental control system is also disclosed.

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