Abstract
A gas turbine engine component is disclosed having a composite construction. In one embodiment the gas turbine engine component is a blade that includes a shroud. A fiber ply of the composite construction extends from an airfoil part of the blade to the shroud. The shroud can include multiple plies that can be stitched together. In one form a sealing knife is formed and coupled to the shroud. The sealing knife can be coupled to the shroud by stitching. Filler material can be used in the composite construction of the gas turbine engine component.
Claims20
An apparatus comprising:
- a gas turbine engine airflow member having an airfoil portion and a shroud portion and constructed from a composite material construction including a matrix and a plurality of fiber plies, at least one of the fiber plies extending from the airfoil portion to the shroud portion.
An apparatus comprising:
- a gas turbine engine turbomachinery component having a plurality of airfoil members capable of directing a flow stream through the component, each of the plurality of airfoil members made from a composite material and having a tip shroud integral with a portion of the airfoil member extending from a hub of the gas turbine engine turbomachinery component.
An apparatus comprising:
- a gas turbine engine rotatable blade having an airfoil part and a shroud disposed at an end of the blade, the blade made of a composite construction having a ply and a matrix;
- and
- means for forming the shroud from a ply of the airfoil part.
A method comprising:
- engaging a ply of a composite construction with a device that forms a blade shape of a gas turbine engine component;
- laying up the ply such that the ply extends from an airfoil part of the blade shape and continues to a shroud part of the blade shape;
- and
- coupling a plurality of plies of the blade shape with a matrix material to form the composite construction.
