DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5An embodiment of the present invention provides a rotary engine, comprising a compression turbofan 10, a working cylinder 20, a compression cylinder 30, a working turbofan 40, an air inlet pipe 510, an air outlet pipe 520, and an explosion chamber 60. The compression turbofan 10 is, for example, an axial flow compressor. The working cylinder 20 is provided with a working cylinder air inlet 210 and a working cylinder air outlet 220, and the compression turbofan 10 is connected to the working cylinder 20. The compression cylinder 30 is located on the side of the working cylinder 20 away from the compression turbofan 10, and is provided with a compression cylinder air inlet 310 and a compression cylinder air outlet 320. The working turbofan 40 is connected to the compression cylinder 30 and is located on the side of the compression cylinder 30 away from the working cylinder 20. The working turbofan 40 is provided with a turbofan air inlet 410 and a turbofan air outlet 420. The turbofan air inlet 410 is connected to the working cylinder air outlet 220 through a first pipe 910. One end of the inlet pipe 510 connects to the compressor turbofan 10, and the other end passes through the working cylinder 20 before connecting to the compressor cylinder air inlet 310. One end of the outlet pipe 520 connects to the turbofan outlet 420 of the working turbofan 40, and the other end passes through the compressor cylinder 30 and the working cylinder 20, respectively. The explosion chamber 60 communicates with the compressor cylinder air outlet 320 and the working cylinder air inlet 210, respectively. The working cylinder 20 and the compressor cylinder 30 are connected by a connecting shaft 330.

[0025] The working process of the above-mentioned rotary engine can be as follows:

[0026] Step 1: When the rotary engine is started, the blades in the compression turbofan 10 rotate, and the outside air is sucked in through the compression turbofan 10. Because the blades of the compression turbofan 10 rotate, the outside air undergoes the first stage of compression to form sub-high pressure gas.

[0027] Step 2: The sub-high pressure gas enters the compression cylinder 30 through the air inlet pipe 510 and the compression cylinder air inlet 310. The rotor inside the compression cylinder 30 rotates to compress the sub-high pressure gas, achieving two-stage compression to form high pressure gas.

[0028] In step 3, the high-pressure gas flows out through the compression cylinder outlet 320 and is transported to the explosion chamber 60 through a pipeline. For example, a fuel injector and a spark plug are provided in the explosion chamber 60. The fuel injector in the explosion chamber 60 is opened, and the fuel injector sprays an appropriate amount of fuel to mix with the high-pressure gas to form a mixed high-pressure gas. Then, the spark plug is ignited, and the electric spark generated by the spark plug ignites the mixed high-pressure gas, which quickly explodes and expands to form explosion gas.

[0029] In step 4, the explosion gas enters the working cylinder 20 through the working cylinder air inlet 210 and drives the rotor in the working cylinder 20 to rotate and perform work.

[0030] Step 5: After the working cylinder 20 works, a first-level working exhaust gas is formed. The first-level working exhaust gas passes through the working cylinder outlet 220, the first pipe 910, the turbofan air inlet 410, and finally flows into the working turbofan 40, driving the working turbofan 40 to work. After the explosive gas pushes the rotor of the working cylinder 20 to work in the working cylinder 20, it is converted into a first-stage working exhaust gas. The first-stage working exhaust gas still contains a certain amount of heat energy and kinetic energy. If no secondary work is performed, the remaining energy will be discharged with the exhaust gas, causing energy waste. In order to further utilize the remaining energy in the first-stage working exhaust gas and improve the energy utilization efficiency and power output of the rotary engine, the first-stage working exhaust gas is made to work again in the working turbofan 40, and the first-stage working exhaust gas is further burned in the working turbofan 40. For example, fan blades are provided in the working turbofan 40. The first-stage working exhaust gas pushes the blades of the working turbofan 40 to rotate and work, further converting the energy in the first-stage working exhaust gas into mechanical energy, increasing the total power output of the rotary engine, and thereby maximizing the power.

[0031] In step 6, the secondary exhaust gas generated after the working turbofan 40 works flows into the exhaust pipe 520 through the turbofan outlet 420 and is discharged through the exhaust pipe 520.

[0032] Through the primary compression of the compression turbofan 10, the secondary compression of the compression cylinder 30, the work of the power cylinder 20, and the work of the power turbofan 40, the energy in the air is more fully utilized. First, the two compression processes gradually increase the air pressure, providing more favorable conditions for combustion, and the high-pressure mixed gas formed by it and the fuel burns more fully. Second, during the power stage, the explosive gas is first used to drive the power cylinder rotor to rotate and perform work. The gas is then passed into the power turbofan for a second power generation, further recovering and utilizing the residual energy in the explosive gas, reducing energy waste, improving energy utilization efficiency, and increasing power.

[0033] Among them, the air is compressed into a secondary high-pressure gas after the first stage, and the pressure and density of the air are initially increased, which is conducive to the subsequent mixing with the fuel sprayed out of the explosion chamber 60, and is mixed more evenly with the air, creating better conditions for combustion. On the basis of the first stage compression, the second stage compression further compresses the secondary high-pressure gas to form high-pressure gas. The higher pressure can make the air molecules denser. When the high-pressure gas flows out through the compression cylinder outlet 320 and flows into the explosion chamber 60, the high-pressure gas and the fuel sprayed out of the fuel injector of the explosion chamber 60 are more fully mixed, and the combustion reaction is more intense and complete, reducing the energy loss and pollutant emissions caused by incomplete combustion, thereby releasing more energy and improving the power output of the rotary engine.

[0034] See also Figure 1 and Figure 3In some embodiments, the explosion chamber 60 includes a first explosion chamber 610 and a second explosion chamber 620; the compression cylinder outlet 320 includes a first compression cylinder outlet 321 and a second compression cylinder outlet 322. The first compression cylinder outlet 321 is connected to the working cylinder air inlet 210 through a second pipe 920, and the first explosion chamber 610 is mounted on the second pipe 920; the second compression cylinder outlet 322 is connected to the working cylinder air inlet 210 through a third pipe 930, and the second explosion chamber 620 is mounted on the third pipe 930. The first explosion chamber 610 and the second explosion chamber 620 operate independently, each including an intake stage and a combustion stage. The high-pressure gas formed by the first and second compression stages can enter the first explosion chamber 610 through the first compression cylinder outlet 321 and the second pipe 920, and enter the second explosion chamber 620 through the second compression cylinder outlet 322 and the third pipe 930.

[0035] Specifically, for example, when the first explosion chamber 610 is in the intake stage, the second explosion chamber 620 may be in the combustion stage or the exhaust stage. After the intake of the first explosion chamber 610 is completed, when the fuel injection ignition of the first explosion chamber 610 is in the combustion stage, the high temperature and high pressure environment inside it needs to remain stable to ensure that the combustion reaction can proceed fully and generate sufficient thrust. At this time, the first explosion chamber 610 no longer takes in air to prevent fresh air or mixed gas from entering and interfering with the combustion process. The second explosion chamber 620 may have completed the combustion stage and entered the exhaust stage, or is in the intake stage. When the first explosion chamber 610 completes the combustion stage and the explosion gas after work is discharged and the explosion chamber is in the exhaust stage, the second explosion chamber 620 may have completed the intake stage and is ready to enter the combustion stage.

[0036] Because when the explosion chamber is in the combustion stage, the high temperature and high pressure environment inside it needs to remain stable to ensure that the combustion reaction can proceed fully and generate sufficient thrust. At this time, the explosion chamber no longer takes in air to prevent fresh air or mixed gas from entering and interfering with the combustion process. During the operation of the rotary engine, the compression turbofan 10 is constantly rotating, and is in a state where external air is constantly input. If there is only one explosion chamber, the gas in the combustion stage of the explosion chamber cannot proceed to the next step. It is necessary to wait until the explosion chamber completes the combustion stage and exhausts the gas before it can take in air again. The combustion is discontinuous and the power output is intermittent. A first explosion chamber 610 and a second explosion chamber 620 are provided. When one of the explosion chambers is burning and doing work, the other explosion chamber is ready to take in or exhaust air, ensuring that the rotary engine continues to obtain power, reducing vibration, and improving stability and life.

[0037] See also Figure 1 and Figure 3In some embodiments, the rotary engine further includes a reversing valve 70, which is mounted on the second pipe 920 and the third pipe 930. The reversing valve 70 is respectively connected to the first compression cylinder air outlet 321, the second compression cylinder air outlet 322, the first explosion chamber 610, and the second explosion chamber 620. This allows the first compression cylinder air outlet 321 and the second compression cylinder air outlet 322 to be connected to the first explosion chamber 610, that is, the compression cylinder 30 is connected to the first explosion chamber 610; or allows the first compression cylinder air outlet 321 and the second compression cylinder air outlet 322 to be connected to the second explosion chamber 620, that is, the compression cylinder 30 is connected to the second explosion chamber 620. Specifically, the reversing valve 70 flexibly controls the flow of gas. For example, by rotating the reversing valve 70, the first explosion chamber 610 is connected to the first compression cylinder air outlet 321. At this time, the first explosion chamber 610 is in the intake stage; the second compression cylinder air outlet 322 is closed to the second explosion chamber 620. At this time, the second explosion chamber 620 is in the combustion stage or the exhaust stage. If it is in the combustion stage, it helps to maintain the sealing of the second explosion chamber 620 and avoid gas leakage, thereby ensuring that the pressure in the explosion chamber rises normally and ensures the smooth progress of the combustion process. For example, when the first explosion chamber 610 is in the combustion stage, the reversing valve 70 is rotated to connect the first compression cylinder air outlet 321 and the second compression cylinder air outlet 322 with the second explosion chamber 620, and the first explosion chamber 610 is closed to the first compression cylinder air outlet 321 and the second compression cylinder air outlet 322, so that the second explosion chamber 620 is in the intake stage.

[0038] See also Figure 1 and Figure 3 In some embodiments, the system further includes: a first intake check valve 810, a second intake check valve 820, a first outlet check valve 840, and a second outlet check valve 850; the first intake check valve 810 is installed on the second pipe 920 and is located between the first explosion chamber 610 and the reversing valve 70, and the second intake check valve 820 is installed on the third pipe 930 and is located between the second explosion chamber 620 and the reversing valve 70. By providing the first intake check valve 810 and the second intake check valve 820, the high-pressure mixed gas is prevented from rebounding from the explosion chamber to the compression cylinder during the working phase of the explosion chamber, ensuring that the high-pressure mixed gas can be effectively burned, thereby improving combustion efficiency and the performance of the rotary engine.

[0039] Furthermore, the first gas outlet one-way valve 840 is installed on the second pipe 920 and is located between the first explosion chamber 610 and the working cylinder air inlet 210, and the second gas outlet one-way valve 850 is installed on the third pipe 930 and is located between the second explosion chamber 620 and the working cylinder air inlet 210. By providing the first gas outlet one-way valve 840 and the second gas outlet one-way valve 850, it is ensured that the explosion gas after the combustion stage is completed will not flow back into the first explosion chamber 610 or the second explosion chamber 620 after being discharged, thereby interfering with the entry and compression process of the fresh mixed gas.

[0040] See also Figure 3 In some embodiments, the rotary engine further includes a tee 940 connecting the second pipe 920, the third pipe 930, and the working cylinder air inlet 210. Tee 940 can combine the airflow exiting the first and second explosion chambers 610, 620, into one path, making the airflow out of the first and second explosion chambers 610, 620 more uniform and stable, and making the system more compact. This helps improve system integration and reduce manufacturing and maintenance costs.

[0041] See also Figure 1 and Figure 4 In some embodiments, the working cylinder 20 includes a first working cylinder 230 and a second working cylinder 240 distributed along the axial direction of the rotary engine, the compression turbofan 10 is connected to the first working cylinder 230, and the working cylinder air inlet 210 includes a first working cylinder air inlet 211 connected to the first working cylinder 230 and a second working cylinder air inlet 212 connected to the second working cylinder 240. The second pipeline 920 includes a first sub-segment 921 and a second sub-segment 922 that are interconnected, the first sub-segment 921 is connected to the first compression cylinder air outlet 321, the second sub-segment 922 is connected to the first working cylinder air inlet 211 and the second working cylinder air inlet 212, and the first explosion chamber 610 is installed on the first sub-segment 921; the third pipeline 930 includes a third sub-segment 931 and a fourth sub-segment 932 that are interconnected, the third sub-segment 931 is connected to the second compression cylinder air outlet 322, the fourth sub-segment 932 is connected to the second sub-segment 922, so as to be connected to the first working cylinder air inlet 211 and the second working cylinder air inlet 212, and the second explosion chamber 620 is installed on the third sub-segment 931.

[0042] Specifically, the explosion gas generated after the first explosion chamber 610 is in operation can pass through the first subsection 921 and the second subsection 922 in sequence and then be respectively introduced into the first working cylinder 230 and the second working cylinder 240, thereby driving the first rotor 231 in the first working cylinder 230 to perform work and the second rotor 241 in the second working cylinder 240 to perform work. Similarly, the explosion gas generated after the second explosion chamber 620 is in operation can pass through the third subsection 931 and the fourth subsection 932 in sequence and then be respectively introduced into the first working cylinder 230 and the second working cylinder 240, thereby driving the first rotor 231 in the first working cylinder 230 to perform work and the second rotor 241 in the second working cylinder 240 to perform work. That is, the explosion gases generated by the first explosion chamber 610 and the second explosion chamber 620 after operation can drive the first working cylinder 230 and the second working cylinder 240 to work, so that the high-temperature and high-pressure gases generated by the first explosion chamber 610 and the second explosion chamber 620 can be more fully utilized, and each working cylinder can obtain energy from the two explosion chambers, thereby improving the overall power output of the rotary engine and reducing energy waste.

[0043] Furthermore, for example, two working cylinder air outlets 220 are also provided, and the two working cylinder air outlets 220 correspond one-to-one to the first working cylinder 230 and the second working cylinder 240. The first pipeline 910 includes, for example, a fifth sub-segment and a sixth sub-segment that are interconnected, the fifth sub-segment is connected to the two working cylinder air outlets 220, and the sixth sub-segment is connected to the turbofan air inlet 410.

[0044] See also Figure 4 In some embodiments, a synchronous wheel 250 is further provided within the working cylinder 20. A first rotor 231 is provided within the first working cylinder 230, and a second rotor 241 is provided within the second working cylinder 240. One end of the synchronous wheel 250 is connected to the first rotor 231, and the other end is connected to the second rotor 241, enabling the first and second rotors 231, 241 to rotate synchronously. The provision of the synchronous wheel 250 ensures that the first and second rotors 231, 241 rotate at the same speed and in the same direction, achieving coordinated motion, reducing vibration and impact caused by the asynchronous motion of the first and second rotors 231, 241, and improving the smooth operation of the rotary engine. The synchronous wheel 250 may, for example, include two meshing gears. The first rotor 231 may, for example, include two first sub-rotors, and the second rotor 241 may, for example, include two second sub-rotors. Each gear is connected to one first sub-rotor and one second sub-rotor.

[0045] See also Figure 1 and Figure 3In some embodiments, a first gas outlet check valve 840 and a second gas outlet check valve 850 are further included. The first gas outlet check valve 840 is located on the first subsection 921 and at the end of the first explosion chamber 610 close to the working cylinder 20. The second gas outlet check valve 850 is located on the third subsection 931 and at the end of the second explosion chamber 620 close to the working cylinder 20. This ensures that the explosion gas after the combustion stage is completed will not flow back into the first explosion chamber 610 or the second explosion chamber 620 after being discharged, thereby interfering with the intake and compression process of the fresh mixed gas.

[0046] See also Figure 1 and Figure 3 In some embodiments, the rotary engine further includes a supercharger injector 430 and a third intake check valve 830. The supercharger injector 430 and the third intake check valve 830 are mounted on the first pipe 910, and the third intake check valve 830 is located between the supercharger injector 430 and the working cylinder outlet 220. If the remaining energy in the primary working exhaust gas discharged after step 4 is insufficient to meet the power requirement or if the explosion gas after the first working operation is not fully burned, it is necessary to supercharge the primary working exhaust gas discharged after the working cylinder 20 performs work. Specifically, the primary working exhaust gas is subjected to secondary combustion by the supercharger injector 430 to increase its pressure and temperature. The gas then enters the working turbofan 40 through the first pipe 910 and the turbofan inlet 410, where it continues to explode and propels the blades of the working turbofan 40 to perform work, thereby increasing the working capacity of the working turbofan 40 and providing greater power output. Finally, the exhaust gas is discharged through the turbofan outlet 420 and the outlet pipe 520.
