  • Stator vane shiplap seal assembly
    Patent number: 10113438
    Abstract: A stator vane shiplap assembly is provided. The stator vane shiplap assembly may comprise a plurality of stator clusters, coupled together to form an annular shape. Each stator cluster may comprise a shiplap stator shroud and a plurality of stator vanes. The shiplap stator shroud may comprise a female end and a male end, with each end comprising a complimentary forward shiplap surface and outward shiplap surface. In response to a coupling of adjacent shiplap stator shrouds, the female forward shiplap surface and the female outward shiplap surface may form a compound shiplap seal joint with the male forward shiplap surface and the male outward shiplap surface. A feather seal may also be introduced between the coupling of adjacent shiplap stator shrouds.
