Method for controlling temperature of a turbine engine compressor and compressor of a turbine engine |
| 摘要 |
According to one aspect of the invention, a method for temperature control of a turbine engine compressor includes directing a fluid from a first region proximate a main flow path in a downstream portion of a structure in a compressor to an upstream portion of the structure, wherein the fluid is cooled as the fluid flows through the upstream portion of the structure. The method further includes directing the fluid from the upstream portion of the structure downstream to a second region of the compressor to cool the second region, wherein the fluid is directed through passages in the upstream and downstream portions of the structure thereby substantially conserving an energy of the fluid within the structure and wherein a pressure of the second region is less than a pressure of the first region. |

1. A method for temperature control of a turbine engine compressor, the method comprising:
directing a fluid from a first region proximate a main flow path in a downstream portion of a structure in a compressor to an upstream portion of the structure, wherein the fluid is cooled as the fluid flows through the upstream portion of the structure; and directing the fluid from the upstream portion of the structure downstream to a second region of the compressor to cool the second region, wherein the fluid is directed through passages in the upstream and downstream portions of the structure thereby substantially conserving an energy of the fluid within the structure and wherein a pressure of the second region is less than a pressure of the first region; wherein directing the fluid from the first region proximate the main flow path in the downstream portion of the structure comprises directing the fluid from a downstream portion of a stator to an upstream portion of the stator; and wherein directing the fluid from the upstream portion of the structure downstream to the second region of the compressor to cool the second region comprises directing the fluid to the second region including a rotor wheel in a last stage of a rotor located radially inside the stator. |
