A gas turbine engine strut fairing (10, 110) includes: inner and outer bands; a hollow, airfoil-shaped vane (12, 112) extending between the bands; wherein the fairing (10, 110) is split along a transverse plane passing through the bands and vane (12, 112), defining a nose piece (24, 124) and a tail piece (26, 126); wherein the vane (12, 112) is defined by a spaced-apart sidewalls (18) extending between a leading edge and a trailing edge, each the sidewalls (18) being split into forward and aft portions by the transverse plane; wherein each of the sidewall portions carries a radially-inwardly extending post (32, 34, 132, 134), having a mating face (40, 46, 140, 146), the posts (32, 34, 132, 134) positioned with pairs of the posts (32, 34, 132, 134) lie adjacent to each other, with their respective mating faces (40, 46, 140, 146) contacting each other; and a pair of slotted buckles (38, 138), each buckle (38, 138) surrounding and clamping together a pair of the posts (32, 34, 132, 134); wherein a mechanical element (76, 143) engages the mating faces (40, 46, 140, 146) of the paired posts (32, 34, 132, 134), so as to block relative radial movement of the paired posts (32, 34, 132, 134).
La présente invention se rapporte à un carénage de support de moteur à turbine à gaz (10, 110) qui comprend : des bandes interne et externe ; une aube de forme profilée (12, 112) qui s'étend entre les bandes ; le carénage (10, 110) est divisé le long d'un plan transversal qui passe à travers les bandes et l'aube (12, 112), ce qui définit une pièce de nez (24, 124) et une pièce de queue (26, 126) ; l'aube (12, 112) étant définie par des parois latérales espacées (18) qui s'étendent entre un bord d'attaque et un bord de fuite, chaque paroi latérale (18) étant divisée en parties avant et arrière par le plan transversal ; chaque partie de paroi latérale supportant un montant s'étendant radialement vers l'intérieur (32, 34, 132, 134), comportant une face de contact (40, 46, 140, 146), les montants (32, 34, 132, 134) étant positionnés avec leurs faces de contact respectives (40, 46, 140, 146) qui viennent en contact les unes avec les autres ; et une paire de boucles inclinées (38, 138), chaque boucle (38, 138) entourant et fixant ensemble une paire de montants (32, 34, 132, 134) ; un élément mécanique (76, 143) venant en prise avec les faces de contact (40, 46, 140, 146) des montants appariés (32, 34, 132, 134) de sorte à bloquer un mouvement radial relatif des montants appariés (32, 34, 132, 134).
