Title
(EN) INTER-MODULE FINGER SEAL
(FR) JOINT D'ÉTANCHÉITÉ À DOIGTS ENTRE MODULES
Abstract
(EN) An assembly for a gas turbine engine includes a first module, a second module, and a finger seal. The second module is connected to the first module along a joint. The finger seal is connected to the first module at a fixed end and has a free end that cantilevers from the fixed end to contact the second module. The finger seal acts to seal the joint between the first module and second module from an ingestion gas flow of the gas turbine engine.
(FR) L'invention porte sur un ensemble pour un moteur à turbine à gaz, lequel ensemble comprend un premier module, un second module et un joint d'étanchéité à doigts. Le second module est relié au premier module le long d'un joint. Le joint d'étanchéité à doigts est relié au premier module à une extrémité fixe, et a une extrémité libre qui est en porte-à-faux à partir de l'extrémité fixe de façon à venir en contact avec le second module. Le joint d'étanchéité à doigts agit de façon à rendre étanche le joint entre le premier module et le second module vis-à-vis d'un écoulement de gaz d'ingestion du moteur à turbine à gaz.
