Abstract
A stator assembly for use in a gas turbine engine is provided. The stator assembly including: a conical stator shroud including a radially inward surface and a radially outward surface opposite the radially inward surface; and a plurality of stator vanes integrally attached to the conical stator shroud, each of the plurality of stator vanes being integrally attached to the conical stator shroud at a base of the stator vane, wherein radially outward surface of the base of the stator vane mates flush with the radially inward surface of the conical stator shroud.
Claims18
A stator assembly for use in a gas turbine engine, the stator assembly comprising:
- a conical stator shroud including a radially inward surface and a radially outward surface opposite the radially inward surface;
- and
- a plurality of stator vanes integrally attached to the conical stator shroud, each of the plurality of stator vanes being integrally attached to the conical stator shroud at a base of the stator vane, wherein radially outward surface of the base of the stator vane mates flush with the radially inward surface of the conical stator shroud.
A method of manufacturing a stator assembly for use in a gas turbine engine, the method comprising:
- inserting a stator vane into a vane slot in a radially inward surface of a conical stator shroud;
- moving the stator vane through the vane slot such that the stator vane projects out of the vane slot from a radially outward surface the conical stator shroud;
- and
- securely attaching the stator vane to the conical stator shroud at a base of the stator vane, such that a radially outward surface of the base of the stator vane mates flush with the radially inward surface of the conical stator shroud.
A gas turbine engine, comprising:
- a compressor section;
- a turbine section;
- a stator vane assembly located in at least one of the compressor section and the turbine section, the stator vane assembly comprising:
- a conical stator shroud including a radially inward surface and a radially outward surface opposite the radially inward surface;
- and
- a plurality of stator vanes integrally attached to the conical stator shroud, each of the plurality of stator vanes being integrally attached to the conical stator shroud at a base of the stator vane, wherein radially outward surface of the base of the stator vane mates flush with the radially inward surface of the conical stator shroud.
