  • Gas turbine engine seal
    Patent number: 4415309
    Abstract: A gas turbine engine is provided with an annular sealing element which is adapted to provide a gas seal between relatively rotatable gas turbine components. The sealing element is in the form of a woven fabric which has metallic warp filaments, metallic weft filaments and metallic warp pile filaments. The free ends of the warp pile filaments are non-looped. The sealing element is brazed to one of the gas turbine engine components so that the free ends of the warp pile filaments abut the other gas turbine engine component in sealing engagement.
