A radial flow turbine heat engine includes a compressor, a recuperator, a combustor and a turbine. A compressor outlet manifold collects compressed gas from the compressor through a plurality of compressor outlets. A turbine inlet manifold supplies combustion gas to the turbine through a plurality of turbine inlets. The compressor outlet manifold comprises a plurality of compressor outlet manifold ducts and the turbine inlet manifold comprises a plurality of turbine inlet manifold ducts. These manifold ducts are circumferentially interdigitated with respect of each other around the shaft of the turbine to provide a flow path for compressed gas through the recuperator located radially inwardly with respect to the rotation axis of the shaft compared to the flow path for the combustion gas in the hot side portion of the heat engine. Furthermore, a flow path for the combustion gas is provided to the turbine inlets which are radially inward with respect to the rotation axis of the shaft compared to flow paths for the compressed gas within the compressor outlet manifold proximal to those turbine inlets.
