Fuel gas-steam combined cycle equal-pressure variable capacitance slide piece rotor engine

The invention discloses a fuel gas-steam combined cycle equal-pressure variable capacitance slide piece rotor engine, and the engine is similar to an ideal variable high-efficiency combustion gas turbine. A stator shaped like an involute curved surface, a cylindrical rotor, a rotor shaft, a rotor cover, a slide piece assembly, a side cover and a combustor form a basic acting system. The stator, the rotor, the side cover and a slide piece enable the interior to be divided into an air gradual compression chamber (like multistage compression) and a gradual expansion chamber (multistage expansion) which is large in size and acts through fuel gas after combustion. During operation, the rotor rotates to inhale air from an air inlet, carries out gradual compression while the slide piece moves, and enables air to enter the combustor from a compressed air outlet and to be mixed with fuel gas. The gas absorbs heat to expand in an equal pressure manner. Because the compression area of an expansion chamber slide piece is larger than the compression area of a compression chamber slide piece by several times and the pressure intensities are equal, the thrust at the expansion chamber side is greater than the resistance of the compression chamber by several times, an external acting force moment is formed, and an equal-pressure expansion work is done. The expanded gas is divided by the slide piece in the expansion room, and the size of the expanded gas becomes large in operation, and then an adiabatic expansion work is done.
