A generator is installed on and provides electrical power from a turbine by converting the turbine's mechanical energy to electricity. The generated electrical power is used to power controls of the turbine so that the turbine can remain in use through its own energy. The turbine can be a safety-related turbine in a nuclear power plant, such that, through the generator, loss of plant power will not result in loss of use of the turbine and safety-related functions powered by the same. Appropriate circuitry and electrical connections condition the generator to work in tandem with any other power sources present, while providing electrical power with properties required to safely power the controls.

A gas turbine engine includes a compressor and a turbine; a plurality of rotor blades positioned in the compressor or the turbine and arranged in a plurality of stages along an axial direction; an outer drum positioned at least partially radially outward of the plurality of rotor blades and rotatable with the plurality of rotor blades; and a casing extending over the outer drum and defining a plurality of air cavities with the outer drum, the plurality of air cavities arranged in series airflow communication along the axial direction.

An internal combustion engine is equipped with a turbocharger that includes: a centrifugal compressor impeller; an axial flow turbine wheel coupled to the compressor impeller via a rotational shaft; a bearing that supports the rotational shaft; and a housing that houses at least the compressor impeller and the bearing among the compressor impeller, the bearing and the turbine wheel. The turbine wheel is coupled to the rotational shaft such that an outlet of turbine blades of the turbine wheel is located on the side of the compressor impeller. The compressor impeller is arranged such that an inlet of the compressor impeller becomes closer to the turbine wheel than an outlet of the compressor impeller.
