A composite stator vane for a gas turbine engine comprising a plurality of compression molded, heat cured plies, the plies including a plurality of centrally located internal plies of reinforcement material of unidirectional yarns of para-aramid fibers, a plurality of plies of resin impregnated graphite fiber material on each side of the centrally located plies of reinforcement material, and an external steel wire mesh ply on the leading edge of the vane.

Insertable stator vane assembly

A turbofan engine fan stator assembly includes stator vanes readily insertable through the outer shroud into the stator assembly hub. Elastomeric grommets seal between the vanes, shroud and hub, and an outer band radially inwardly compresses the assembly. The vanes are radially secured to the hub only through frictional engagement with the hub grommet.

A seal compression tool is disposed at a readily accessible location externally of the cylindrical casing of a gas turbine engine, and has a camming surface thereon effective to interengage and axially shift the turbine nozzle of the gas turbine engine. Such axial shifting uniformly and controllably compresses a static seal carried between the turbine nozzle and the casing at a remote, relatively inaccessible location inside the gas turbine engine.
