Abstract
High inertia and large bearing loads encountered in monorotors for gas turbine engines are reduced in a monorotor having a compressor wheel section (,) made of a relatively low density material while the turbine wheel section (,) maintains resistance to heat by being made of a relatively higher density, heat resistant material. The two are joined into a monorotor through the use of two bodies (,) which are inertia welded to the respective wheels (,) and then welded together by any one of a variety of welding processes.
