The central shaft is in gear engagement with the power generation assembly through a gear box 8.

The engine process is started.

The central shaft is rotated by external force (by means of a motor, a leather strip and the like) to drive the device;

① centrifugal compressor operates to force air in, and initially at a low speed, approximately 1-2 atmospheres.

② static pressure chamber obtains air flow with pressure, the gas is sucked to mix the gas and air, the static pressure is 1-2 atmospheric pressure.

③ drives the first rotor to rotate, and the air inlet valve channel rotates to the random space between two cylinders.

④ when the exhaust valve rotates to the first combustion chamber and the second combustion chamber, the first combustion chamber and the second combustion chamber are blocked from the exhaust valve by the second rotor.

⑤ acting blades stop rotating, do not work, and do not drive the central shaft.

High-pressure gas generation:

① centrifugal compressor sucks air from atmosphere, and sucks fuel gas from static pressure chamber according to preset ratio.

② static pressure chamber generates 1-2 atm static pressure, and enters the air inlet channel, and the mixed gas flows into the first combustion chamber and the second combustion chamber because of the pressure difference which is larger than the standard atmospheric pressure.

③ ignites the second combustion chamber, which detonates, and the expansion pressure is within 10-15 atmospheres.

④ the central shaft rotates 120 degrees continuously to reach the second and third combustion chambers.

⑤ the pressure in the second combustion chamber now creates a pressure differential across the third combustion chamber, the pressure in the second combustion chamber is reduced by half and the pressure in the third combustion chamber is half that in the second combustion chamber.

⑥ differential pressure airflow flows through the inlet channel, the fluid pressure is reduced, the pressure is reduced to 1-2 atmospheric pressure in the inlet channel contraction ratio, at this time, the static pressure chamber reaches 2-4 atmospheric pressure under the high speed rotation of the centrifugal shaft due to the continuous rotation, the mixed gas is dragged to the third combustion chamber along the airflow direction, and the compression stroke is formed.

⑦ the central shaft rotates continuously at 120-240 deg.C, the exhaust valve opens to do work outwards at 5-8 atmospheres in the second combustion chamber, and drives the turbine of the turbine part to rotate, thus generating electricity, which is the power stroke.

⑧ the exhaust valve is rotated at 120-240 degrees to release the second combustion chamber pressure to near atmospheric pressure, which is the exhaust stroke.

And (3) continuous exhaust process:

① when the central shaft rotates 240 degrees, the centrifugal compressor operates at high speed to reach 3-5 atmospheric pressure, and the static pressure chamber is at 3-5 atmospheric pressure.

② the third combustion chamber is ignited for expansion to atmospheric pressure within 20 atmospheres.

③ the intake valve path is intake.

④ the central shaft rotates 240 degrees and 360 degrees, the third combustion chamber exhausts.

Detonation rotating valve jet generator state:

three cylinders, one shaft, two valves, plastic centrifugal shaft compressor and fuel mixing static pressure chamber.

The three cylinders are divided into a first combustion chamber, a second combustion chamber and a third combustion chamber; one shaft is a central shaft, the central shaft of the turbine part and the central shaft of the miniature centrifugal shaft air compressor; the additional fuel mixing chamber is the static pressure chamber. Two valves, an exhaust valve and an air inlet valve.

The whole operation is divided into 360-degree rotation of the central shaft, and is a cycle. Every 120 degrees of rotation is a process, and the intake valve and the exhaust valve rotate 120 degrees.

The flow is introduced by a common jet engine and is divided into air intake, compression, expansion and exhaust.

The four strokes represent a 120 degree process. Four strokes are performed simultaneously in geometric space during 120 degrees one pass.

Three points are satisfied first. Air is fed into the air inlet branch cylinder and the air inlet channel, and high-pressure air is discharged by the centrifugal shaft air compressor.

Step one, air intake in a cylinder: namely into the mixed gas.

Air inlet of the air inlet channel: the high-pressure gas in the expansion chamber is discharged into the cylinder for air intake, mainly pressure difference.

The mixed gas sucked by the air inlet channel flows into the cylinder air inlet chamber.

The theoretical process is as follows: a high velocity airflow is generated in the intake passage. The fluid is dragged in the direction of the fluid due to the surface tension of the fluid, like a tornado. There is also a faster fluid velocity and a lower pressure. The gas in the inlet channel is far less than the pressure in the expansion chamber. The gas mixed in the gas inlet chamber is sucked.

Air inlet of a centrifugal shaft air compressor: air and fuel are drawn into the mixing intake chamber at a specific ratio.

The theoretical process is as follows: the gas mixing inlet chamber is used for providing 3-5 atmospheric pressures under the miniature centrifugal shaft gas compressor. The gas is forced into the inlet valve. And (3) how the mixing air inlet chamber sucks the mixing chamber with a specific ratio, and calculating the suction air by the air injection speed of the fuel and the rotating speed of the centrifugal shaft compressor.

And the second step is a 120-degree air injection theoretical picture of one process. The process was run at 20 atmospheres in the expansion chamber.

The starting process is satisfied: the central shaft is rotated to make the air inlet channel turn to the first and second combustion chambers, and the two cylinders suck in mixed gas under the condition of 1-2 atmospheric pressures of the initial compressed air of the air compressor. Currently only the second combustion chamber is ignited. A second combustion chamber expansion stroke. As with natural gas explosions, the mixing of gas and air at a detonation limit ratio, at one atmosphere, produces an explosion of 20 atmospheres.

And step three, a 120-degree process.

An intake stroke: the second combustion chamber expands to force air into the third combustion chamber below the inlet. The theoretical process is as follows: this is the suction stroke, which draws in the mixture, during the pressure difference. Because the expansion pressure of the second combustion chamber is greater than the atmospheric pressure of the third combustion chamber. At the moment, the pressure of the air inlet channel is 1-2 under the fluid air pressure. Centrifugal shaft compressors are 3-5, so that air suction is greatly increased.

Compression stroke: and simultaneously, a compression stroke is carried out, and the third combustion chamber inhales mixed gas and compresses the mixed gas under certain conditions. The theoretical process is as follows: the air is compressed because of the static pressure created by the high velocity air flow exiting the second combustion chamber through the intake port.

And (3) power stroke: when the central shaft rotates 120-240 degrees. The second combustion chamber also has a certain residual pressure under 1-10 atmospheric pressures. Under the exhaust valve, work is done outwards.

Exhaust stroke: high-pressure tail gas is discharged to reach the atmospheric pressure in the exhaust chamber. The operation was carried out at 120 degrees.

Three times continuously, 360 degrees and one circulation.

This is the pressure difference between the two sections of the inlet valve. After the expansion chamber is at 20 atmospheres and the air is discharged into the cylinder inlet chamber, if the volume is the same and the temperature is the same, the air density is high. One atmosphere is ignored. The theory is that the cylinder inlet chamber is half of the expansion chamber, and the expansion chamber is reduced to half of the original expansion chamber. That is to say at 20 atmospheres in the expansion chamber. After the gas is pressed in. Expansion chamber to exhaust chamber >10 atmospheres. The air inlet chamber in the cylinder is less than or equal to 10 atmospheric pressures.
