Abstract

Une tuyère orientable (12) comprend des sections convergentes et divergentes (14 et 16) et une gorge (18) entre elles. Des parois supérieure et inférieure (30 et 32) espacées sur le sens de la hauteur délimitent vers lextérieur un passage pour le flux de tuyères (40) et sétendent vers larrière au travers des sections convergentes et divergentes (14 et 16) de lentrée de la tuyère (19) jusquà la sortie de la tuyère (20). La paroi supérieure (30) comprend des panneaux supérieurs convergents triangulaires gauche et droit (26 et 28) montés de façon pivotante à une rampe supérieure convergente triangulaire (23) dans la section convergente (14) le long daxes darticulation à angle convergents latéraux gauche et droit (27 et 29) respectivement. La paroi supérieure (30) comprend en outre des panneaux supérieurs divergents triangulaires gauche et droit (36 et 38) fixés de façon pivotante à une rampe supérieure divergente triangulaire (35) dans la section divergente (16) le long daxes darticulation à angle divergents latéraux gauche et droit (37 et 39) respectivement. Les panneaux supérieurs convergents gauche et droit (26, et 28) sont en prise détanchéité avec les panneaux supérieurs divergents gauche et droit (36 et 38) le long dinterfaces supérieures latérales gauche et droite (60 et 62) respectivement.
