Title (EN) TURBOMACHINE WITH BLOW‑OFF VALVES LOCATED AT THE INTERMEDIATE CASE
(FR) TURBOMACHINE Á VANNES DE DÉCHARGE LOCALISÉES AU NIVEAU DU CARTER INTERMÉDIAIRE
Abstract:
(EN) Assembly consisting of an intermediate case (7) of a bypass turbojet engine and of an inter‑jet case (10) extending upstream of said intermediate case to separate the primary air jet of the turbojet engine from its bypass air jet, said inter‑jet case having, passing through it, a closable duct (16) for diverting part of the primary flow to the bypass flow thereby forming a blow-off valve for the LP compressor, said intermediate case comprising arms (6) passing across the bypass flow and said inter‑jet case in its internal cavity comprising a first chamber situated upstream of said arms (6) and a second chamber (12) situated level with said arms, said duct being open or closed off by an annular component capable of axial movement (14) set in motion by an arm (17) that can rotate about a fixed pivot (18) under the action of a control cylinder (15), characterized in that said cylinder is positioned in the second chamber (12).
(FR) Ensemble constitué d'un carter intermédiaire (7) d'un turboréacteur double flux et d'un carter interveines (10) s'étendant en amont dudit carter intermédiaire pour séparer la veine d'air primaire du turboréacteur de sa veine d'air secondaire, ledit carter interveinesétant traversé par un conduit obturable (16) de dérivation d'une partie du flux primaire vers le flux secondaire formant vanne de décharge pour le compresseur BP, ledit carter intermédiaire comportant des bras (6) traversant le flux secondaire et ledit carter interveines comportant dans sa cavité intérieure une première enceinte située en amont desdits bras (6) et une seconde enceinte (12) située au niveau desdits bras, ledit conduit étant ouvert ou obturé par une pièce annulaire à déplacement axial (14) mise en mouvement par un bras (17) mobile en rotation autour d'un pivot fixe (18) sous l'action d'un vérin de commande (15), caractérisé en ce que ledit vérin est positionné dans la seconde enceinte (12).
