Abstract

A first component of the gas turbine engine (2), such as the hub (10), is heated from a second component, such as the shaft (12), by induction heating using a flexible heating sheath (40) wrapped around the outer circumferential surface (18) of the hub. Parts are assembled or disassembled. The jacket (40) includes a conductive flexible cable (42) having a plurality of rings (44). The jacket is selectively opened and closed with a plurality of electrical connectors (54) coupled to each respective ring of the cable. The power supply (64) passes current through the corresponding cable loops, which heats the hub. Induction heating is applied to mating parts in the engine to create a sufficient temperature differential that allows assembly or disassembly of the hub and shaft. A controller (30) regulates the power applied to the hub and shaft and monitors their temperature with temperature sensors (15, 16).

Description

[0001] This application claims priority to and is a continuation-in-part of U.S. Patent Application Serial No. 62 / 570,265 filed October 10, 2017, the contents of which are incorporated herein by reference . technical field [0002] The disclosed embodiments relate to assembly and disassembly of turbine engine components. More specifically, some of the disclosed embodiments relate to assembly and disassembly of turbine engine hubs (including power take-off hubs) and mating shafts. Background technique [0003] A gas turbine engine typically includes a housing or cylinder for housing a compressor section, a combustion section, and a turbine section. The air supply is compressed in the compressor section and directed into the combustion section. Compressed air enters the combustion inlet and mixes with fuel. The air / fuel mixture is then combusted to produce high temperature and high pressure (working) gases. The working gas then travels through the transition section and in...
