An engine, a rotary device, a power generation system, and methods of manufacturing and using the same are disclosed. The engine includes a detonation and/or combustion chamber configured to detonate a fuel and rotate around a central rotary shaft extending from the detonation and/or combustion chamber, a fuel supply inlet configured to provide the fuel to the detonation and/or combustion chamber, at least two rotating arms extending radially from the detonation and/or combustion chamber and configured to exhaust detonation gases from detonating the fuel in the detonation and/or combustion chamber and provide a rotational thrust and/or force, the rotating arms having inner and outer walls and a nozzle at a distal end thereof, the nozzle being at or having an angle configured to provide the rotational thrust and/or force, and a plurality of cooling coils between the inner and outer walls. Alternatively, the rotary device may include a rotary disc.

A wave disc engine apparatus is provided. A further aspect employs a constricted nozzle in a wave rotor channel. A further aspect provides a sharp bend between an inlet and an outlet in a fluid pathway of a wave rotor, with the bend being spaced away from a peripheral edge of the wave rotor. A radial wave rotor for generating electricity in an automotive vehicle is disclosed in yet another aspect.

An engine, a power generation system, and methods of manufacturing and using the same are disclosed. The engine includes a detonation/combustion chamber configured to detonate a fuel and rotate around a central rotary shaft extending from the chamber, a fuel supply inlet configured to provide the fuel to the chamber, an air supply channel configured to supply air to the chamber, at least two rotating arms extending radially from the chamber and configured to exhaust gases from detonating the fuel in the chamber and provide a rotational thrust and/or force, and a mechanical work unit configured to receive at least part of the rotational thrust and/or force. Each of the rotating arms has an exhaust nozzle at a distal end thereof, the exhaust nozzle being at or having an angle configured to provide the rotational thrust and/or force.

Aspects of the present disclosure are directed to apparatuses and methods involving a turbine blade that rotates with a shaft, which may be implemented with a round or toroidal-based engine housing. As may be implemented with some embodiments, an apparatus includes a shaft and turbine blade having a common axis of rotation, with each drive shaft operable to rotate independently of the other drive shaft. A housing extends around the shaft and turbine blade and has sidewall with inlet and exhaust ports. In some implementations, clutch bearings limit rotation of the drive shaft to a common rotational direction. The turbine blade and inner surface of the sidewall define chambers and operable to move circumferentially within the chamber about the axis of rotation, with the shaft to which it is coupled, and to drive the turbine blade using gas supplied via the inlet port(s) and exhausted vie the exhaust port(s).
