Title
(EN) JET NOZZLE EQUIPPED WITH A THERMALLY REGULATED RING
(FR) TUYERE EQUIPEE D'UNE COURONNE THERMO-REGULEE
Abstract
(EN)
A jet nozzle (100) comprises a combustion chamber (110) which has a downstream end (111) and a divergent nozzle section (120) made of a cone-shaped wall (121) extending between an upstream end (122) and a downstream end. The upstream end (122) of the divergent nozzle section is connected to the downstream end (111) of the combustion chamber by an intermediate ring (130) comprising an upstream flange (131) fixed to a fixing flange (112) that forms an integral part of the combustion chamber (110) and a downstream flange (132) connected to the upstream end (122) of the divergent nozzle section (120). The intermediate ring (130) comprises an internal duct (133) present between the upstream and downstream flanges (131, 132) of the intermediate ring (130). A material (160) able to remove heat from the ring is present in the internal duct (133).
(FR)
Une tuyère (100) comprend une chambre de combustion (110) présentant une extrémité aval (111) et un divergent (120) formé d'une paroi (121) en forme de cône s'étendant entre une extrémité amont (122) et une extrémité aval. L'extrémité amont (122) du divergent est reliée à l'extrémité aval (111) de la chambre de combustion par une couronne intermédiaire (130) comprenant une bride amont (131) fixée sur une bride de fixation (112) solidaire de la chambre de combustion (110) et une bride aval (132) reliée à l'extrémité amont (122) du divergent (120). La couronne intermédiaire (130) comprend un canal interne (133) présent entre les brides amont et aval (131, 132) de la couronne intermédiaire (130). Un matériau (160) apte à prélever de la chaleur sur la couronne est présent dans le canal interne (133).
