ABSTRACT:
A combustion chamber for a gas-turbine engine is disclosed in which the walls defining the combustion chamber may be easily attached to and removed from the engine structure. A dome member is attached to the engine structure such that it partially encloses the fuel injector nozzle in an upstream direction. The shape of the dome-member is such that it splits the incoming oxidizer flow into inner and outer flows which pass along the inner and outer sides of the combustion chamber. The inner and outer walls of the combustion chamber may be attached to an upstream end wall of the combustion chamber such that this assembly is removable as a unit from the dome member. The inner and outer walls, as well as the end wall, are releasably attached to the dome member such that the assembly can be removed from the gas-turbine engine without the necessity of removing or displacing the fuel injector nozzles or the dome member. Alternatively, the end wall of the combustion chamber is fixedly attached to the dome member while the inner and outer walls of the combustion chamber are releasably attached to the end wall. This enables the inner and outer walls to be separately removed from the gas-turbine engine, again without disturbing the fuel injector nozzles or the dome member.
