Abstract
A compressor adapted for use in for a gas turbine engine includes a diffuser and a housing. The diffuser is arranged circumferentially around an axis and includes a fore plate, an aft plate spaced apart axially from the fore plate to define a flow path therebetween, and a plurality of vanes that extend between the fore plate and the aft plate. The housing is arranged circumferentially about the axis and located adjacent the diffuser.
Claims20
A compressor adapted for use in for a gas turbine engine, the compressor comprising
- an impeller configured to rotate about an axis to provide compressed air,
- a diffuser arranged circumferentially around the impeller and configured to diffuse the compressed air received from the impeller, the diffuser including a diffuser body aligned axially with an outlet of the impeller to capture the compressed air and a locating baffle fixed with the diffuser body for movement with the diffuser body, the diffuser body includes a fore plate, an aft plate spaced apart axially from the fore plate to define a flow path configured to receive the compressed air from the impeller, and a plurality of vanes that extend between the fore plate and the aft plate to interact with the compressed air flowing through the diffuser body,
- a housing arranged circumferentially about the axis and located adjacent the diffuser,
- wherein the locating baffle is engaged with a first portion of the housing and urges the diffuser body away from the first portion of the housing and toward a second portion of the housing and the locating baffle is configured to deform elastically to allow the diffuser body to move relative to the first portion of the housing and the second portion of the housing during use of the compressor.

- a housing arranged circumferentially about the axis and located adjacent the diffuser,
- wherein the locating baffle is configured to deform elastically to allow the diffuser body to move relative to the housing and is engaged with a first portion of the housing to bias the diffuser body away from the first portion of the housing and toward a second portion of the housing.
A method comprising
- providing an impeller configured to rotate about an axis to provide compressed air, a diffuser configured to diffuse the compressed air received from the impeller, and a housing, the diffuser including a diffuser body and a locating baffle configured to deform elastically,
- fixing a first end of the locating baffle to the diffuser body for movement with the diffuser body,
- arranging the diffuser circumferentially around the impeller so that the diffuser body is aligned axially with an outlet of the impeller,
- arranging the housing adjacent to the diffuser, and
- engaging a second end of the locating baffle with a first portion of the housing to bias the diffuser body away from the first portion of the housing and toward a second portion of the housing.
