A combustion chamber (44) which has a primary combustion zone (52) and a secondary combustion zone (56) is pro- vided with a plurality of secondary fuel and air mixing ducts (88) arranged around the primary combustion zone (44). The secondary fuel and air mixing ducts (88) are defined by a pair of annular walls (92, 90) and by a plurality of walls (94) ex- tending radially between the annular walls (90, 92). Each secondary fuel and air mix- ing duct (88) has an aperture (104) to di- rect a fuel and air mixture into the sec- ondary combustion zone (56). The aper- tures (104) have the same flow area. Each secondary fuel and air mixing duct (88) has one or more fuel injectors (100) to inject fuel into the upstream end of the secondary fuel and air mixing duct (88) where air enters through an inlet (98). This arrangement ensures that the fuel/air ratio emitted from each aperture (104) is within 3.0 % of the mean fuel/air ratio of all the apertures (104) even though the air flow to the secondary fuel and air mixing ducts (88) is non uniform.

Une chambre de combustion (44), qui comprend une zone de combustion principale (52) et une zone de combustion secondaire (56), est pourvue d'une pluralité de conduites secondaires (88) de mélange de combustible et d'air disposées autour de la zone de combustion principale (44). Les conduites secondaires (88) de mélange de combustible et d'air sont délimitées par une paire de parois annulaires (92, 90) et par une pluralité de parois (94) qui s'étendent radialement entre les parois annulaires (90, 92). Chaque conduite (88) de mélange comprend une ouverture (104) permettant de diriger un mélange combustible/air dans la zone de combustion secondaire (56). Les ouvertures (104) présentent la même section de passage. Chaque conduite (88) de mélange comporte un ou plusieurs injecteurs (100) de combustible permettant d'injecter du combustible dans l'extrémité amont de la conduite secondaire (88) de mélange, au niveau duquel l'air est introduit par une admission (98). Cet agencement assure que le rapport combustible/air émis par chaque ouverture (104) ne dépasse pas 3,0 % du rapport moyen combustible/air de toutes les ouvertures (104) même si l'écoulement d'air vers les conduites secondaires (88) de mélange est irrégulier.
