Abstract

Est concernée une chambre de combustion annulaire de turbine à gaz, comportant des viroles annulaires interne et externe reliées par un fond de chambre au niveau duquel sont disposés des systèmes d'injection de carburant et comburant comprenant des injecteurs (28) de carburant montés dans des passages de moyens (29) d'apport de comburant comprenant chacun : - au moins une vrille (54,56) de mise en rotation du comburant présentant des canaux de passage de comburant, - et un diaphragme (31) de réglage de la quantité de comburant admis dans ladite chambre de combustion et disposé sensiblement au niveau de ladite vrille. Chaque diaphragme (31) comprend une bague (35) fixe vis-à-vis de laquelle les moyens d'apport de comburant peuvent bouger, par dilatation thermique, de sorte à faire varier la quantité de comburant passant à travers le diaphragme en fonction de la température, par obturation plus ou moins importante des canaux de la vrille.
