Abstract

Tuyère comportant un dispositif diminuant les fuites entre les volets. Elle comporte deux volets articulés coulissant axialement l'un sur l'autre 24, 26, le volet recouvert 26 comportant des fentes axiales qui reçoivent les nervures 38 du volet en recouvrement 24, un dispositif d'étanchéité 64 monté flottant à l'extrémité aval du volet 24 avec lequel il se déplace axialement et coulisse dans la fente en appui sur des sièges formés dans la fente pour obturer la partie apparente de la fente. Application, notamment, aux tuyères asymétriques dites à deux dimensions.
