METHOD AND APPARATUS TO REDUCE TURBINE ENGINE NOZZLE BASE SHEET STRESS

摘要

PROBLEM TO BE SOLVED: To provide a method and device for reducing stress of a base sheet of a gas turbine engine exhaust nozzle. SOLUTION: An assembly 100 for the gas turbine engine exhaust nozzle 30 includes a backbone 104 and a base sheet 106 configured to couple to the backbone. The base sheet includes at least one relief cut 200 and a pair of circumferentially-spaced sides 114 and 116 coupled together by an upstream side 110 and a downstream side 112. At least one relief cut extends from at least one of the circumferentially-spaced sides towards the other respective circumferentially-spaced side. COPYRIGHT: (C)2005,JPO&NCIPI
