Description

Technical Field

[0001] The present invention relates to the technical field of rocket engines, and more specifically to an intelligent hybrid power regulation system for a rocket engine. Background Art

[0002] A rocket engine is a reaction propulsion device that does not rely on an external medium (such as air) and generates thrust by high-speed jetting of a working fluid (combustion products), and is suitable for the space environment. Its core principle follows Newton's third law (action and reaction) and the law of conservation of momentum.

[0003] A hybrid rocket engine combines the characteristics of solid and liquid rocket engines. It usually uses solid fuel and liquid or gaseous oxidizer, and adjusts the thrust by regulating the oxidizer flow rate. Its technical characteristics lie between the simplicity of solid engines and the controllability of liquid engines.

[0004] Currently, when the existing hybrid rocket engine is in operation, due to the use of a pumping supply and only one pipeline, the flow rate of the fuel can only be controlled by a pump, and fuel diversion supply cannot be carried out. Therefore, the existing hybrid rocket engine cannot perform fuel diversion supply and pressure strengthening work during use. Therefore, an equipment is needed to improve the above problems.

[0010] Specifically, the diversion device includes a limit bottom plate, a fuel cavity, branch valves, a photoelectric sensor, a connecting pipeline, and a combustion chamber. The limit bottom plates are symmetrically and fixedly installed at the top of the opposite side ends of the fuel cavity.

[0016] Advantages of the present invention:

[0017] First, when the hydraulic cylinder is started in the present invention, the first piston rod can be driven to move downward through the connecting rod, so that the first piston rod can extrude the gas inside the built-in cavity, thereby increasing the pressure inside the fuel cavity. At the same time, due to the one-way valve between the fuel cavity and the built-in cavity, the backflow inside the fuel cavity can be avoided. Moreover, the air valve can be controlled to open or close as the first piston rod rises or falls, so that it is convenient to pressurize each time the first piston rod enters the built-in cavity, and the work of strengthening the supply pressure inside the fuel cavity is completed.

[0018] Second, when the first piston rod moves downward in the present invention, it can drive the diversion pipeline to communicate with the branch valve. At the same time, the branch valve can be opened, facilitating the fuel inside the fuel cavity to enter the interior of the diversion pipeline through the branch valve. Through the communication between the diversion pipeline and the connecting pipeline, the fuel finally enters the combustion chamber through the connecting pipeline for combustion. At this time, when the first piston rod enters the interior of the built-in cavity, the pressure can be transmitted to the interior of the fuel cavity, thereby increasing the speed of the fuel passing through the branch valve and the connecting pipeline, and completing the work of diverting the fuel to the diversion pipeline.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Embodiment 1

[0033] As Figure 1 and Figure 2 shown, an intelligent hybrid control system for a rocket engine of the present invention includes a housing 2. Inside the housing 2, control components 1 are symmetrically and fixedly installed, and the control components 1 are distributed in a ring shape. At the bottom end of the housing 2, a nozzle 3 is fixedly installed, and the nozzle 3 is distributed in a ring shape. The control component 1 includes an outer cover 41, a displacement device 4, a pressurization device 5, a transmission device 6, and a diversion device 7. The diversion device 7 is fixedly installed at the inner bottom end of the outer cover 41. The transmission device 6 is fixedly installed at the top end of the outer cover 41. The displacement device 4 is fixedly installed at the bottom end of the transmission device 6. The pressurization devices 5 are symmetrically and fixedly installed at the top end of the diversion device 7.

[0034] As Figure 3 、 Figure 4 and Figure 5, the displacement device 4 includes a connecting base frame 8, a diversion pipeline 9, a first rack 10, a special-shaped support 11, a U-shaped support frame 12, a first piston rod 13, a connecting round rod 14, a connecting bottom plate 15, a first spring 16, an L-shaped air cylinder 17, a second piston rod 18, a special-shaped extension plate 19, a matching extension plate 20, a third piston rod 21, a second rack 22, a displacement cross plate 23, a second spring 24 and an extension cross frame 25. The U-shaped support frame 12 is symmetrically and fixedly installed on the top side end of the first piston rod 13. The connecting round rod 14 is fixedly installed on the side end of the U-shaped support frame 12. The connecting bottom plate 15 is fixedly installed at the bottom end of the connecting round rod 14. The first spring 16 is fixedly installed at the top end of the connecting bottom plate 15 away from the connecting round rod 14. The connecting base frame 8 is fixedly installed at the top end of the first spring 16. The diversion pipeline 9 is fixedly installed at the bottom end of the connecting base frame 8. The extension cross frame 25 is symmetrically and fixedly installed at the bottom of the side end of the U-shaped support frame 12 away from the connecting round rod 14. The displacement cross plate 23 is slidably sleeved on the extension cross frame 25. The second spring 24 is fixedly installed between the U-shaped support frame 12 and the displacement cross plate 23. The L-shaped air cylinder 17 is fixedly installed at the bottom of the side end of the U-shaped support frame 12 close to the extension cross frame 25. The second piston rod 18 is slidably inserted into the top end inside the L-shaped air cylinder 17.

The matching extension plate 20 is fixedly installed at the bottom of the side end of the U-shaped support frame 12 facing away from the first piston rod 13. The second rack 22 is fixedly installed at the bottom end of the displacement cross plate 23. The third piston rod 21 is slidably inserted into the bottom end inside the L-shaped air cylinder 17. Since the U-shaped support frame 12 is arranged in a U shape, it can be avoided that when the first piston rod 13 moves downward, the U-shaped support frame 12 interferes with the built-in cavity 26.

[0035] As Figure 6 , the pressurizing device 5 includes a built-in cavity 26, a top support 27, a gear 28 and an air valve 29. The air valve 29 is symmetrically and fixedly installed at the bottom of the side end of the built-in cavity 26. The gear 28 is fixedly installed on the side end of the air valve 29 facing away from the built-in cavity 26. The top support 27 is symmetrically and fixedly installed at the top of the side end of the built-in cavity 26 close to the air valve 29. Since a one-way valve is installed at the bottom end of the built-in cavity 26, it can be avoided that the fuel inside the fuel cavity 34 enters the inside of the built-in cavity 26.

[0036] As Figure 7 , the transmission device 6 includes a cross base frame 30, a connecting rod 31 and a hydraulic cylinder 32. The cross base frame 30 is fixedly installed at the top end of the hydraulic cylinder 32. The connecting rod 31 is symmetrically and fixedly installed at the bottom end of the cross base frame 30, and can support the up and down movement of the cross base frame 30.

[0037] As Figure 8, the flow guiding device 7 includes a limit bottom plate 33, a fuel cavity 34, branch valves 35, photoelectric sensors 36, connecting pipes 37 and a combustion chamber 38. The limit bottom plate 33 is symmetrically and fixedly installed at the top of the opposite side ends of the fuel cavity 34. The fuel cavity 34 is symmetrically and fixedly installed at the top end of the combustion chamber 38. The branch valves 35 are symmetrically and fixedly installed at the bottom of the opposite side ends of the fuel cavity 34, and the photoelectric sensors 36 are fixedly installed on the side ends of the branch valves 35. The connecting pipes 37 are symmetrically and fixedly installed at the top end of the combustion chamber 38, and the connecting pipes 37 are located between the two fuel cavities 34. By connecting the fuel cavity 34 and the combustion chamber 38 through a pump and a pipeline, the pump can be started, so that the fuel can be normally transported from the fuel cavity 34 to the inside of the combustion chamber 38.

[0038] The built-in cavity 26 is fixedly installed at the top end of the fuel cavity 34. The combustion chamber 38 is fixedly installed inside the outer cover 41. The hydraulic cylinders 32 are symmetrically and fixedly installed at the top end inside the outer cover 41. The bottom end of the connecting rod 31 is connected to the top end of the first piston rod 13. The first piston rod 13 is slidably inserted into the inside of the built-in cavity 26. The inside of the flow guiding pipe 9 is provided in a hollow state, and the flow guiding pipe 9 is vertically aligned with the connecting pipe 37 and the branch valve 35. The branch valve 35 communicates with the inside of the fuel cavity 34. A one-way valve is installed at the bottom end of the built-in cavity 26. The air valve 29 communicates with the inside of the built-in cavity 26. Limit partitions are symmetrically and fixedly installed at the top of the side end of the built-in cavity 26 close to the air valve 29, and through holes adapted to the connecting round rod 14 are opened in the limit partitions. The special-shaped extension plate 19 is horizontally aligned with the matching extension plate 20. The inside of the L-shaped air cylinder 17 is provided in a hollow state, and a sealed cavity is formed among the L-shaped air cylinder 17, the second piston rod 18 and the third piston rod 21. The top bracket 27 is vertically aligned with the matching extension plate 20 and the special-shaped extension plate 19. The bottom ends on both sides of the top bracket 27 are inclined at 30°. A one-way valve is installed between the connecting pipe 37 and the combustion chamber 38. The limit bottom plate 33 is vertically aligned with the third piston rod 21. The third piston rod 21 is 5 cm longer than the second rack 22. A square key is fixedly installed at the side end of the connecting bottom plate 15 close to the connecting base 8, and a square groove is opened on the inner side of the connecting base 8 close to the connecting round rod 14.

[0039] The working principle of Embodiment 1 is as follows: When in use, when thrust enhancement is required inside the combustion chamber 38, the hydraulic cylinder 32 can be activated to drive the cross base 30 and the connecting rod 31 to move downward. Since the first piston rod 13 is installed at the bottom end of the connecting rod 31, when the connecting rod 31 moves downward, it can drive the first piston rod 13 to move downward. At this time, the first piston rod 13 can enter the interior of the built-in cavity 26 and compress the air inside the built-in cavity 26. The bottom end of the built-in cavity 26 is connected to the top end of the fuel cavity 34 through a one-way valve. When the first piston rod 13 enters the interior of the built-in cavity 26, it can compress the gas inside the built-in cavity 26 to enter the interior of the fuel cavity 34 through the one-way valve, thereby increasing the pressure inside the fuel cavity 34. At the same time, when the first piston rod 13 moves downward, it can also drive the connecting round rod 14 and the U-shaped support frame 12 to move downward simultaneously. When the connecting round rod 14 moves downward, it can drive the connecting bottom plate 15 and the connecting base 8 to move downward simultaneously. Moreover, when the first piston rod 13 enters the interior of the built-in cavity 26, the connecting bottom plate 15 can drive the diversion pipeline 9 to be inserted and sleeved on the branch valve 35 and the connecting pipeline 37, completing the work of making the branch valve 35, the diversion pipeline 9, and the connecting pipeline 37 communicate with each other. At the same time, the diversion pipeline 9 can also contact the photoelectric sensor 36 to open the branch valve 35. At this time, the branch valve 35 can release the fuel inside the fuel cavity 34. At the same time, it can cooperate with the continuous movement of the first piston rod 13 into the interior of the built-in cavity 26 to enable the fuel inside the fuel cavity 34 to quickly enter the interior of the combustion chamber 38 through the branch valve 35, the diversion pipeline 9, and the connecting pipeline 37, completing the work of distributing and transmitting fuel, effectively increasing the speed of fuel entering the interior of the combustion chamber 38. At the same time, when the first piston rod 13 moves downward and is about to reach the bottom end inside the built-in cavity 26, it can drive the second rack 22 to contact the gear 28, thereby driving the gear 28 and the air valve 29 to rotate, enabling the gas inside the built-in cavity 26 to be discharged outward through the air valve 29. Subsequently, when the first piston rod 13 continues to move downward, it can drive the third piston rod 21 to contact the limit bottom plate 33. Through the blocking of the limit bottom plate 33, the third piston rod 21 can enter the interior of the L-shaped air cylinder 17. Thus, the second piston rod 18 can drive the special-shaped extension plate 19 to move to adsorb and fit with the matching extension plate 20, driving the second rack 22 to disengage from the gear 28, preventing the second rack 22 from driving the gear 28 to displace in the reverse direction when the first piston rod 13 returns upward. At the same time, when the diversion pipeline 9 contacts the branch valve 35, due to the installation of the first spring 16 between the connecting base 8 and the connecting bottom plate 15, the connecting bottom plate 15 can continue to move downward while keeping the diversion pipeline 9 sleeved on the branch valve 35 and the connecting pipeline 37. Subsequently, the hydraulic cylinder 32 can be activated again to drive the connecting rod 31 to move upward, so that the first piston rod 13 moves upward inside the built-in cavity 26. At this time, due to the air valve 29 being in an open state, the outside gas can enter the interior of the built-in cavity 26 through the air valve 29,It is convenient for the first piston rod 13 to reset upward. Moreover, when the first piston rod 13 moves upward, the second rack 22 will not contact the gear 28, preventing the air valve 29 from closing in advance. Subsequently, when the connecting bottom plate 15 moves upward, the first spring 16 can be gradually compressed. Thus, the connecting bottom plate 15 can squeeze the first spring 16 to drive the connecting base frame 8 and the diversion pipeline 9 to move upward, facilitating the disengagement of the diversion pipeline 9 from the branch valve 35. At this time, the diversion pipeline 9 will also disengage from the photoelectric inductor 36, causing the photoelectric inductor 36 to lose the induction signal and closing the branch valve 35 to prevent the branch valve 35 from releasing fuel and flowing outward. When the first piston rod 13 moves out of the internal cavity 26, the first rack 10 can contact the gear 28. Thus, when the first piston rod 13 continues to move upward, it can drive the first rack 10 to pass through the gear 28, and the gear 28 can drive the air valve 29 to rotate in the reverse direction to close the air valve 29. Subsequently, when the first piston rod 13 moves upward to the limit position, it can drive the first rack 10 to separate from the gear 28. Moreover, the top bracket 27 can contact the junction of the special-shaped extension plate 19 and the mating extension plate 20 to separate the mating extension plate 20 and the special-shaped extension plate 19. At this time, the elasticity of the second spring 24 will drive the displacement cross plate 23 to move toward the end close to the U-shaped support frame 12. Thus, the displacement cross plate 23 can drive the second rack 22 to reset, facilitating the alignment of the second rack 22 with the surface of the gear 28. When the second rack 22 moves downward again, it can engage with the surface of the gear 28. When the first piston rod 13 moves upward to the limit position, the L-shaped air cylinder 17 will not contact the top bracket 27, avoiding interference. Moreover, when the displacement cross plate 23 resets, it can drive the second rack 22 to move simultaneously. When the second rack 22 moves, it can drive the first rack 10 and the special-shaped bracket 11 to move simultaneously. Thus, the first rack 10 can be misaligned with the gear 28, preventing the first piston rod 13 from driving the first rack 10 to contact the gear 28 when moving downward, completing the work.

[0040] Embodiment 2

[0041] Based on Embodiment 1, as Figure 9 shown, the diversion pipeline 9 further includes a flow valve 39 and a support side frame 40. The support side frame 40 is symmetrically and fixedly installed at the side end of the diversion pipeline 9, and the flow valve 39 is fixedly installed inside the support side frame 40.

[0042] When implementing this embodiment, through the setting of the support side frame 40, the installation of the flow valve 39 can be supported. At the same time, since the flow valve 39 is located inside the diversion pipeline 9, it is convenient to monitor the liquid flow inside the diversion pipeline 9. By connecting the flow valve 39 to an external display terminal, the data monitored by the flow valve 39 can be transmitted to the display terminal in a timely manner, facilitating personnel to understand the fuel consumed when increasing the thrust, completing the work.
