Abstract
A one-piece air exit port baffle for containment for an air start turbine includes a circular arc section with a circumferentially corrugated circular arc section and a flange section. The circumferentially corrugated circular arc section has a plurality of openings. The flange section is axially adjacent to the circumferentially corrugated circular arc section and configured for attachment adjacent to an air exit port of an air turbine starter.
Claims20
An one-piece air exit port baffle for containing or deflecting fragments within an air turbine starter having an annular air flow channel extending from an air inlet port in a generally axial direction through an air turbine and then in a generally radial direction to an annular air exit port, the one-piece air exit port baffle comprising:
- a circumferentially corrugated circular arc section having a plurality of openings therein;
- and
- a flange section axially adjacent to the circumferentially corrugated circular arc section and configured for attachment adjacent to an air exit port of an air turbine starter.
An air turbine starter comprising:
- an air inlet port;
- an air turbine connected to an output shaft to start an engine;
- an annular air flow channel extending from the air inlet port to the air turbine;
- an air exit port;
- a radial air flow channel extending from the air turbine to the air exit port, wherein air flowing from the air inlet port through the air turbine and out the air exit port provides power for starting the engine;
- and
- a one-piece baffle fixed in position to cover the air exit port to contain fragments within the air turbine starter, the baffle comprising:
- a circumferentially corrugated circular arc section having a plurality of openings therein;
- and
- a flange section axially adjacent to the circumferentially corrugated circular arc section and configured for attachment to the air turbine adjacent to the air exit port;
- wherein the baffle is fixed in position by attachment of the flange section to the air turbine starter.
A method for manufacturing a one-piece baffle for containing or deflecting fragments within an air turbine starter having an annular air flow channel extending from an air inlet port in a generally axial direction through an air turbine and then in a generally radial direction to an annular air exit port, the method comprising:
- forming a plurality of openings in a sheet;
- stamping the sheet having the plurality of openings to form a corrugation and a flange;
- and
- bending the stamped sheet into a one-piece circular arc section shape.
