Abstract
A vane assembly has an outer support ring, an inner support ring, an outer liner ring, an inner liner ring, and a circumferential array of vanes. Each vane has a shell extending from an inboard end to an outboard end and at least partially through an associated aperture in the inner liner ring and an associated aperture in the outer liner ring. There is at least one of: an outer compliant member compliantly radially positioning the vane; and an inner compliant member compliantly radially positioning the vane.
Claims22
A vane assembly comprising:
- an outer support ring;
- an inner support ring;
- an outer liner ring;
- an inner liner ring;
- and
- a circumferential array of vanes, each having:
- a shell extending from an inboard end to an outboard end and at least partially through a respective associated aperture in the inner liner ring and an associated aperture in the outer liner ring;
- and
- at least one of:
- an outer compliant member compliantly radially positioning the shell relative to the outer support ring;
- and
- an inner compliant member compliantly radially positioning the shell relative to the inner support ring,
- wherein:
- each inner compliant member or each outer compliant member comprises a canted coil spring;
- and
- for said each inner compliant member or each outer compliant member, there are flowpaths between turns of the canted coil spring to permit air to flow from a space between an associated one of the outer support ring and inner support ring and an associated one of the outer liner ring and inner liner ring into an interior of the associated vane.
