Integral inner and outer shrouds and vanes

摘要

The inner shroud of the vane of a vane assembly for the compressor section of a gas turbine engine is fabricate from a composite material preferably imide resin reinforced with carbon fibers and is formed into an open ended box-like member segment supporting no less than two vanes or airfoils. The segments are interlocked by a necked down edge adapted to slip into the open end of the adjacent inner shroud of the stator vane that serve to seal the gas path and provide damping. Rub strips are integrally formed on the bottom surface of the inner shroud.
