ABSTRACT:
An annular combustor structure particularly suited to staged combustion has a faired centrebody incorporating a diffuser in the head of the combustor. The structure carries fuel injector mountings for pilot and main stage combustion which receive fuel from respective manifolds running around the hollow interior of the structure. There are two annular chambers each containing a fuel manifold, and cooling air passes through the chambers before entering the combustion volume. The manifolds are connected to an external source of fuel by conduits which pass radially through the combustion chamber outer casing walls.
