Abstract: This invention relates to a combustor heat shield assembly for a containment ring for use in a radial inflow turbine engine having a compressed air supply and a combustor. The combustor heat shield assembly includes a turbine nozzle assembly which is adapted for receiving a mixture of compressed air and combustion by-products delivered by the combustor to drive a turbine impeller of the radial inflow turbine engine about an axis of rotation. The turbine nozzle assembly is integrally connected with and in close radial proximity to the containment ring. A heat shield, provided with slots, is coupled to the turbine nozzle assembly and thermally adapted for providing a circumferentially uniform seal between the turbine nozzle assembly and the heat shield during operation of the radial inflow turbine engine.
