Turbine shroud for air cycle machine
View Patent ↗A turbine shroud for an air cycle machine includes a wall inner surface which at least partially defines a turbine flowpath, the wall inner surface defined by set of points in Table T-1 scaled by a desired factor.
1. A turbine shroud for an Air Cycle Machine comprising:
a wall inner surface which at least partially defines a turbine flowpath, said wall inner surface defined by a set of points in Table T-1 scaled by a desired factor, said set of points include paired radial dimensions from a centerline of the turbine shroud and axial dimensions from a flange mount surface of the turbine shroud.
2. The turbine shroud as recited in claim 1 , wherein a wall having said wall inner surface defines a thickness defined at least partially for blade containment.
3. The turbine shroud as recited in claim 1 , wherein a wall having said wall inner surface defines a shroud section and a flange section.
4. The turbine shroud as recited in claim 3 , wherein said flange mount surface is defined by said flange section.
5. The turbine shroud as recited in claim 1 , wherein said wall inner surface defined by said set of points in Table T-1 is adjusted by a manufacturing tolerance.
6. The turbine shroud as recited in claim 5 , wherein said manufacturing tolerance is about +−0.03 inches (0.76 mm).
7. An Air Cycle Machine comprising:
a turbine shroud having a wall inner surface which at least partially defines a turbine flowpath, said wall inner surface defined by a set of points in Table T-1 scaled by a desired factor, said set of points include paired radial dimensions from a centerline of the turbine shroud and axial dimensions from a flange mount surface of the turbine shroud.
8. The Air Cycle Machine as recited in claim 7 , wherein said turbine shroud is downstream of a turbine nozzle.
9. The Air Cycle Machine as recited in claim 7 , further comprising a turbine rotor within said turbine rotor shroud.
10. The Air Cycle Machine as recited in claim 7 , wherein said wall inner surface defined by said set of points in Table T-1 is adjusted by a manufacturing tolerance.
11. The Air Cycle Machine as recited in claim 7 , wherein said manufacturing tolerance is about +−0.160 inches (4 mm).
12. A method of assembling an Air Cycle Machine comprising:
mounting a turbine shroud to a turbine nozzle to at least partially define a turbine flowpath with a wall inner surface of the turbine rotor shroud, the wall inner surface defined by a set of points in Table T-1 scaled by a desired factor, the set of points include paired radial dimensions from a centerline of the turbine shroud and axial dimensions from a flange mount surface of the turbine shroud.
13. The method as recited in claim 12 , further comprising:
mounting the turbine shroud downstream of the turbine nozzle.
14. The method as recited in claim 13 , further comprising:
mounting a turbine rotor downstream of the turbine nozzle and within the turbine shroud.
15. The method as recited in claim 12 , further comprising:
adjusting the wall inner surface defined by the set of points in Table T-1 by a manufacturing tolerance.
