Abstract

A gas turbine engine comprises a ring comprising an inner ring and an outer ring that define a gas path therebetween; a vane disposed in the gas path and supported by the inner ring and the outer ring, the vane includes an inner platform, an outer platform, and an airfoil section disposed therebetween, wherein the inner ring and the outer ring include one or more of: a flange designed to abut an opposing flange defined by the inner platform, the outer platform or both, and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode; a contact surface designed to abut an opposing contact surface defined by the inner platform, the outer platform or both, and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode; and, an angled contact surface designed to abut an opposing angled contact surface defined by the inner platform, the outer platform or both, and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode.

Dependent claims

A gas turbine engine, comprising:

a turbine section disposed about an engine axis, the turbine section including a ring comprising an inner ring and an outer ring that define a gas path therebetween;
at least one vane disposed in the gas path and supported by the inner ring and the outer ring, the vane includes a lower platform, an upper platform, and an airfoil section disposed therebetween,
wherein at least one of the inner ring and the outer ring include one or more of the following:
(i) at least one aft end or fore end designed to abut an opposing surface defined by at least one of the lower platform and the upper platform and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode,
(ii) at least one contact surface designed to abut an opposing contact surface defined by at least one of the lower platform and the upper platform and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode, and
(iii) at least one angled contact surface designed to abut an opposing angled contact surface defined by at least one of the lower platform and the upper platform and permit axially aftward movement until abutment occurs to achieve a nominal tolerance mode.
