INTERNAL COMBUSTION ENGINE
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.
Magnetic-drive axial-flow fluid displacement pump and turbine
What is disclosed are embodiments of magnetic torque transfer devices utilizing torque transfer by magnetic induction in which an induction cylinder fabricated from an electrical conductor is interposed into the gap between a pair of magnetically coupled primary and secondary rotors. Rotation of the induction cylinder relative to the coupled rotors evokes magnetic torque transfer in accordance with Lenz's Law. The primary rotor rotates within a toroid shaped stator. The stator may be configured for rolling biphasic coil control. The secondary rotor is attached to a propeller. The device may function as a turbine when fluid is directed to flow over the propeller. The device may function as a pump when AC power is supplied to the stator. Rolling biphasic motor control includes dividing motor coils into increments, then configuring groups of contiguous increments into virtual coils, which revolve in tandem with the primary rotor so to achieve continuous and optimal torque transfer with minimum torque ripple.

Fault tolerant turbine speed control system
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.

Pulsed supersonic air-turbine engine with speed control
An electronic speed-controlled pulsed supersonic turbine engine powering automotive, drone, and electric power generation, energized by breathable, clean renewable energy airflow from 2700 psi integral air-tank energizing the engine continuously for 3 hours, replacing the toxic fossil gasoline-diesel energized internal combustion engine with carbon emissions that affect climate change. The turbine blades are turned by the pulsed impulse of supersonic airflow from sequentially energized eight manifolds of de Laval convergence-divergence-CD with sonic choking nozzle and supersonic divergence airflow impulsing turbine blades turning them within divergence shroud to atmospheric pressure with turbine nose with engine output shaft supported with bearings supported by the air-tank. An electric pulse generator controls engine shaft speed with voltage pulses to solenoid valves commanding spool valves with airflow from the air-tank with output shaft magnetic speed sensing signal sent back to controller in closed loop adjusting to desired set with pulse amplitude and time duration.
