The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained. The unique difference between the present invention and general common sense lies in opposite fluid pressure directions; inner fluid channels and outer fluid channels with higher flow speeds are formed to generate pressure differences which guides the fluid pressure to the outside and serve as propelling force, thus the present invention creatively finds three propelling force sources, two lifting force or propelling force sources of helicopters or airplanes driven by propellers and two propelling force sources for sufficient burning of fuel in combustion chambers of engines.

A vibrorotational fluid flow actuator includes: a first vibrorotational component comprising a first body including an axis, a plurality of first legs extending from a bottom surface of first body in a direction of and at an angle to the axis, and a plurality of first blades extending from a respective side of the first body in a direction perpendicular to the axis, wherein when the first vibrorotational component is placed on a chassis, vibration of the chassis induces rotation of the body such that the blades and body rotate about the axis of the body thereby inducing fluid flow in a fluid surrounding the actuator.

A reaction turbine operates on the heat released from the condensation of steam, combined with inherent steam pressure and temperature heads. A series of rotors, each containing multiple curved internal channels, provide compressive boosts between successive stages, while avoiding excessive self-compression. Compressive effects and shock waves generated within these channels provide high levels of condensation, thereby releasing immense amounts of heat. The resulting hot vapor and condensate droplets are then ejected tangentially at the periphery of the rotors to generate thrust. The exhaust steam from the last stage is then compressed and returned to the engine inlet to be mixed with the incoming fresh steam, thereby efficiently completing the system cycle without the need of large cooling towers for condensation.

A super-heated self-compressed air rotary turbine driving a built-in, outside-in axial flux generator is provided for providing power to heaters in thermal communication with the walls of the turbine chambers. Moisture within the working fluid is thus heated, making steam and thereby increasing the pressure of the working fluid. The compression caused by the turbine rotation also increases temperature. The discharge of each turbine chamber is feeding a nozzle. The shaft power drives a main generator, and after passing over the turbine the air stream maintains a portion of its initial energy. The remaining energetic air stream left is then cycled to the compressor, thereby completing the cycle. A main generator driven by the turbine can remain approximately constant, regardless of the load. Input to the compressor can be regulated with the rpm of the compressor motor and the current to the heaters in the turbine.

A screw rocket nozzle may include a disc shaped nozzle body and a spiral flow path having an inlet and an outlet. In some examples the flow path is radial with the inlet positioned at a higher pressure region than the outlet. In other examples the flow path is axial with the inlet positioned at a lower pressure region than the outlet. The nozzle may rotate about its center as a turbine in an axial configuration.

The invention pertains to the field of power engineering and may be applied to convert kinetic and thermal energy of a working medium into mechanical work. The method includes swirling of a pre-compressed working medium, its expansion in an actuating device to produce mechanical work in the form of rotation of the shaft, and discharge of the working medium from the actuating device. The working medium is swirled in the actuating device along a spatial trajectory in the form of a conical helix, the projection of which on a plane positioned at an angle to the axis of rotation is a curve having at least two breakpoints.
