In a gas turbine engine power unit the gas turbine engine is provided with combustion chambers whose axes are perpendicular to the engine longitudinal axis. Each combustion chamber is located within and supported by a corresponding tubular member. Each tubular member is supported from a first annular manifold and in turn supports a second annular manifold which is located wholly within the first manifold. The first manifold receives air from the gas turbine engine compressor and directs it to a regenerative heat exchanger. Heated air returned from the regenerative heat exchanger is directed to the second manifold from where it flows through apertures in the tubular members to the combustion chambers. The manner in which the manifolds and combustion chambers are mounted reduces stresses arising from thermal gradients.
