Abstract: This invention relates to a combustor heat shield assembly for a containment ring (64) for use in a radial inflow turbine engine having a compressed air supply and a combustor (32). The combustor heat shield assembly includes a turbine nozzle assembly (88) which is adapted for receiving a mixture of compressed air and combustion by-products delivered by the combustor (32) to drive a turbine impeller (22) of the radial inflow turbine engine about an axis of rotation (12). The turbine nozzle assembly (88) is integrally connected with and in close radial proximity to the containment ring (64). A heat shield (72), provided with slots (74), is coupled to the turbine nozzle assembly (88) and thermally adapted for providing a circumferentially uniform seal between the turbine nozzle assembly (88) and the heat shield (72) during operation of the radial inflow turbine engine.
