ABSTRACT:
An improved high pressure gas generator rotor for a gas turbine engine is disclosed in which a tie rod of unitary construction provides an axial compressive load across a plurality of non-bolted compressor and turbine components arranged in rotational driving arrangement, for example, by face splines and rabbets. An interim compressive load path solely through the compressor rotor portion is automatically provided upon relaxation of the operational compressive load in the rotor to maintain mechanical integrity of the compressor and facilitate assembly and maintenance activity. An anti-rotated midspan locknut on the tie rod obviates the need for additional, special tooling configured to clamp the compressor components during disassembly of the turbine.
