  • Patent number: 4676715
    Abstract: A turbine ring assembly is mounted on an annular carrier secured to the irior of the casing of a turbine and includes a succession of contiguous sectors of a ceramic abradable material. The sectors have grooves in which support fingers are engaged rigid with an annular member connected to the casing of the turbine. The sectors are thereby held in an annular configuration and the support fingers are so located in the grooves as to provide a screen to prevent reintroduction of hot gases.
