Abstract
A method for assembling and disassembling a module of gas turbine engine is provided, along with a gas turbine engine configured for modular assembly/disassembly. The engine includes a first shaft and a second shaft. The first shaft connects a compressor section and a first turbine section. The second shaft is connected to the second turbine section. The first and second shafts are rotatable about the engine rotational axis. The second shaft and the second turbine section together form a module that can be assembled, or disassembled, or both from the engine.
Claims7
A method of disassembling a gas turbine engine, comprising the steps of:
- providing a gas turbine engine having a rotational axis, a compressor section, a first turbine section, a second turbine section, a first shaft connecting the compressor section and the first turbine section, which first shaft is rotatable about the engine rotational axis, a second shaft connected to the second turbine section, which second shaft is rotatable about the engine rotational axis, a shaft spacer, and a first shaft nut;
- removing the shaft spacer;
- moving the second shaft and the second turbine section axially forward as a module to a disassembly position;
- uncoupling the first shaft nut;
- and
- removing the second shaft and the second turbine section as a module from the gas turbine engine.
