Turbomachine including an adaptable intake system and method of controlling airflow to a turbomachine
View Patent ↗A turbomachine includes a compressor having a compressor intake, and an intake system mounted upstream of the compressor intake. The intake system includes a housing and a plurality of selectively positionable vanes arranged within the housing. The plurality of selectively positionable vanes are moveable between a first position to remove a first amount of foreign particles, and a second position, to remove a second amount of foreign particles.
1. A turbomachine comprising:
a compressor including a compressor intake; and
an intake system mounted upstream of the compressor intake, the intake system including a housing and a plurality of selectively positionable vanes arranged within the housing, the plurality of selectively positionable vanes being moveable between a first position to remove a first amount of foreign particles, and a second position to remove a second amount of foreign particles.
2. The turbomachine according to claim 1 , wherein the intake system includes an inlet region, the plurality of selectively positionable vanes being arranged at the inlet region.
3. The turbomachine according to claim 1 , wherein each of the plurality of selectively positionable vanes includes an entrapment surface, the entrapment surface blocking, at least in part, foreign matter from entering the compressor intake when the plurality of selectively positionable vanes are in the first position.
4. The turbomachine according to claim 3 , wherein each entrapment surface is curvilinear.
5. The turbomachine according to claim 1 , further comprising: a control operatively connected to the plurality of selectively positionable vanes, the control being adapted to shift the plurality of selectively positionable vanes between the first and second position.
6. The turbomachine according to claim 1 , further comprising: a filtering device arranged within the intake system.
7. The turbomachine according to claim 6 , wherein the plurality of vanes are arranged up-stream of the filtering device.
8. The turbomachine according to claim 6 , wherein the plurality of vanes are arranged down-stream of the filtering device.
9. The turbomachine according to claim 6 , wherein the plurality of vanes comprises a first plurality of vanes arranged up-stream of the filtering device and a second plurality of vanes arranged down-stream of the filtering device.
10. The turbomachine according to claim 9 , wherein each of the first and second plurality of vanes is separately controllable.
11. A method of controlling airflow through an intake system for a turbomachine, the method comprising:
positioning a plurality of vanes shiftably mounted at the intake system between a first position, and a second position, wherein when in the first position, the plurality of vanes remove a first amount of foreign particles, and wherein when in the second position, the plurality of vanes remove a second amount of foreign particles.
12. The method according to claim 11 , wherein, when in the first position, partially blocking an inlet of the intake system with entrapment surfaces provided on each of the plurality of vanes.
13. The method of claim 11 , further comprising: automatically shift the plurality of vanes between the first and second positions.
14. The method of claim 11 , further comprising: passing an airflow through a filtering device arranged within the intake system.
15. The method of claim 14 , wherein when in the first position, the plurality of vanes substantially block foreign particles from entering the turbomachine up-stream of the filtering device.
16. The method of claim 14 , wherein when in the first position, the plurality of vanes substantially block foreign particles from entering the turbomachine down-stream of the filtering device.
17. The method of claim 14 , wherein when in the first position, the plurality of vanes substantially block foreign particles from entering the turbomachine up-stream and down-stream of the filtering device.
18. The method of claim 17 , further comprising: independently controlling a first plurality of vanes arranged up-stream of the filtering device and a second plurality of vanes arranged down-stream of the filtering device.
19. The method of claim 11 , wherein positioning the plurality of vanes shiftably mounted at the intake system anywhere between the first position, and the second position comprises rotating the plurality of vanes about a vertical axis.
20. An intake system for a turbomachine comprising:
a housing; and
a plurality of selectively positionable vanes arranged within the housing, the plurality of selectively positionable vanes being moveable between a first position to remove a first amount of foreign particles, and a second position to remove a second amount of foreign particles.
