| 摘要 |
The present invention comprises a gas turbine engine (12) with a compressor for generating compressed air, a turbine (16) comprising upstream and downstream rows of vanes (20), a vane carrier structure (30) surrounding at least one row of vanes (20) and a plenum structure (40) at least partially surrounding the vane carrier structure (30) capable of impinging compressed air onto the vane carrier structure (30). The gas turbine engine (12) further comprises fluid supply structure (46) including first fluid path structure (48) defining a first path for compressed air to travel to the plenum structure (40), second fluid path structure (50) defining a second path for compressed air to travel toward the downstream row of vanes (20), and fluid control structure (52) selectively controlling fluid flow to the first and second fluid path structures (48, 50). |
