Abstract:
A combustion chamber comprising at least one combustion zone defined by at least one peripheral wall, at least one fuel and air mixing duct for supplying a fuel and air mixture to the at least one combustion zone, the at least one fuel and air mixing duct having an upstream end and a downstream end, fuel injection means for supplying fuel into the at least one fuel and air mixing duct, air injection means for supplying air into the at least one fuel and air mixing duct, the pressure of the air supplying to the at least one fuel and air mixing duct fluctuating, the air injection means comprising a plurality of air injectors spaced apart in the direction of flow through the at least one fuel and air mixing duct to reduce the magnitude of those fluctuations in the fuel to air ratio of the fuel and air mixture supplied into the at least one combustion zone, the fuel injector means being arranged between the upstream end and the downstream end of the at least one fuel and air mixing duct, some of the air injector means being arranged upstream of the fuel injector means and some of the air injector means being arranged downstream of the fuel injector means.
