Abstract
There is disclosed a stator vane assembly comprising a support structure 14 arranged to be mounted to a mounting structure 16, a stator vane 12 radially extending from the support structure 14 and a continuity member 28 coupled to the support structure 14 and arranged in use to extend between the mounting structure 16 and the support structure 14 so as to provide a substantially continuous gas-washed surface across the mounting structure 16 and the support structure 14. There is also disclosed a method of forming a stator vane assembly, the method comprising the steps of forming at least one stator vane radially extending from a support structure having a continuity member coupled thereto.
Claims15
A stator vane assembly, comprising:
- a support structure arranged to be mounted to a mounting structure and having first and second circumferentially extending axially spaced rails arranged to be retained within corresponding first and second channels provided in the mounting structure and a circumferentially extending platform section axially extending therebetween;
- a stator vane radially extending from the platform section;
- and
- a continuity member coupled to the support structure and having a first portion disposed between the first rail and the first channel and a second portion disposed between the second rail and the second channel, and a central portion extending across and substantially in contact with the platform section between the first and second portions, thereby providing a substantially continuous gas-washed surface across the mounting structure and the support structure.
