A combustion chamber assembly (22) comprises a primary, a secondary and a tertiary fuel and air mixing ducts (54,78,98) to supply fuel and air to primary, secondary and tertiary combustion zones (40,42,44). Each of the primary, secondary and tertiary fuel and air mixing ducts (54,78,98) comprises a
A combustion chamber assembly (22) comprises a primary, a secondary and a tertiary fuel and air mixing ducts (54,78,98) to supply fuel and air to primary, secondary and tertiary combustion zones (40,42,44). Each of the primary, secondary and tertiary fuel and air mixing ducts (54,78,98) comprises a pair of axial flow swirlers (56,60,80,84,102,104) arranged coaxially to swirl the air in opposite directions and fuel injectors (62, 86,106) to supply fuel coaxially of the respective axial flow swirlers (56,60,80,84,102, 104). Valves (66,90) are provided to control the supply of air to the primary and the secondary fuel and air mixing ducts (54,78) respectively. A duct (122,116) is arranged to supply cooling air and dilution air to the combustion chamber (22). The amount of air supplied to the primary, secondary and tertiary fuel and air mixing ducts (54,78,98) and the duct (122,116) is measured.
