Abstract
One exemplary aspect of this disclosure relates to an assembly for a gas turbine engine having an engine axis. The assembly includes a case including an integrally formed projection configured to extend transverse to the engine axis. The assembly further includes an engine component including a flange configured for contact with the projection to limit motion of the component along the engine axis.
Claims16
An assembly for a gas turbine engine having an engine axis, the assembly comprising:
- a case including an integrally formed projection configured to extend transverse to the engine axis;
- and
- a stator vane including a flange configured for contact with the projection to limit motion of the stator vane along the engine axis, wherein the flange is positioned axially between the case and the projection, and wherein an aft surface of the flange and a fore surface of the projection are configured for contacting one another along an inclined interface relative to the engine axis.
An assembly for a gas turbine engine having an engine axis, the assembly comprising:
- a case including an integrally formed projection configured to extend transverse to the engine axis;
- and
- an engine component including a flange configured for contact with the projection to limit motion of the component along the engine axis, wherein an aft surface of the flange is configured to contact a fore surface of the projection, and wherein the aft surface of the flange and the fore surface of the projection are configured for contacting one another along an inclined interface relative to the engine axis.
A case for a gas turbine engine having an engine axis, the case comprising:
- a stop monolithically formed with the case and configured to circumferentially extend about the engine axis with a fore surface of the stop oriented at an angle relative to the engine axis, wherein the stop is oriented at an acute angle relative to the engine axis.
A component for a gas turbine engine having an engine axis, the component comprising:
- an inner platform including a flange, the flange projecting from a radially inner surface of the inner platform, wherein the flange is configured to be mounted in the engine with an aft surface thereof inclined at an acute angle relative to the engine axis.
