Abstract:
An arrangement for mounting a vane airfoil having a shroud to a gas turbine engine stator structure having radially inner and outer portions, said mounting arrangement characterized by:a first, radially compliant, resilient mount by which said vane, at one end thereof, is mounted to one of said stator portions, said first resilient mount comprising a first spring;a second resilient mount by which said vane airfoil is mounted at an opposite end thereof to the other of said stator portions, said second resilient mount comprising a spring plate being radially and axially compliant;at least one fastener engaging said vane and said first and second resilient mounts for securing said vane to said first and second resilient mounts and said first and second resilient mounts to said stator structure;said second resilient mount being fixed to said shroud by said fastener, and adapted for attachment at a mounting flange thereof, to said stator structure by a second fastener, and further comprising a third spring disposed between said mounting flange and stator structure;wherein said mounting arrangement is compliant in a radial direction for accommodating disparate rates of radial thermal expansion between said vane and said stator structure, and at least one of said resilient mounts is compliant in an axial direction, accommodating disparate rates of axial thermal expansion between said vane and said stator structure.
