GAS TURBINE ENGINE AND ITS INSTALLATION METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an extraction structure for a gas turbine engine in which an installation step becomes advantageous. <P>SOLUTION: A low pressure compressor section 29 of the gas turbine engine has a plurality of shrouds 48, 51, 52 and at least one shroud 51, 52 constitutes a large number of extraction ports 54. A structural hub 68 is fixed to the shroud in a downstream side. A structural case 100 extends from a rear bolt-tightening flange 104 bonded to the structural hub 68 to a front bolt-tightening flange 102 bonded to the shroud 48 and has a plurality of valve ports 110. A valve member 112 can be shifted between the first state wherein communication through the valve port 110 is shut-off and the second state wherein it is not shut-off. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
