Embodiment Construction

[0010]FIG. 1 is a schematic illustration of an exemplary gas turbine engine. A gas turbine engine 100 typically includes a compressor 200, a combustor 300, a turbine 400, and a shaft 120. The gas turbine engine 100 may have a single shaft or a dual shaft configuration. For convention in this disclosure all references to radial, axial, and circumferential directions and measures refer to center axis 95 unless otherwise specified. Center axis 95 may generally be defined by the longitudinal axis of shaft 120. Center axis 95 may be common to or shared with other gas turbine engine concentric components.

[0011]Air 10 enters an inlet 15 as a “working fluid” and is compressed by the compressor 200. Fuel 35 is added to the compressed air in the combustor 300 and then ignited to produce a high energy combustion gas. Energy is extracted from the combusted fuel / air mixture via the turbine 400 and is typically made usable via a power output coupling 5. The power output coupling 5 is shown as bei...

Abstract

A gas turbine engine compressor spacer (230) includes a body (229) with a hollow cylinder shape. The body (229) includes an outer surface (232) with an axially forward end. The body (229) also includes a forward face (233) extending radially inward from the axially forward end. A forward lip (237) extends axially from the body (229). The forward lip (237) includes a forward lip surface (239) located radially inward from the forward face (233). The forward lip surface (239) is the radially outer circumferential surface of the forward lip (237). The spacer (230) also includes a forward undercut (235). The forward undercut (235) is located between the forward face (233) and the forward lip surface (239).

Description

TECHNICAL FIELD[0001]The present disclosure generally pertains to gas turbine engines, and is more particularly directed toward a compressor undercut spacer of a gas turbine engine.BACKGROUND[0002]Gas turbine engines include compressor, combustor, and turbine sections. Components of the gas turbine engine sections are subject to high temperatures and pressures. These temperatures and pressures may vary during transients of the gas turbine engine, especially during start up and shut down of the gas turbine engine. The components may thermally expand at different rates generating thermal stresses and strains within the components.[0003]U.S. Patent Application Pub. No. 2009 / 0297350, to S. Augustine discloses a mount interface between two rotating gas turbine engine components including a rigid ring to provide radial deflection restraint. According to Augustine a hoop snap spacer or rigid ring could be used as a spacer providing connection between rotor stages near a rim where the blade...
