Description

Technical Field

[0001] This invention relates to the field of thermoelectric rocket engine technology, specifically to a vortex-enhanced thermoelectric hybrid rocket engine. Background Technology

[0002] Thermoelectric rocket engines use metallic fuel as a propellant and superheated water as an oxidizer and working fluid. During operation, the metallic fuel reacts with the superheated water to release a large amount of heat, and the generated high-temperature gas is discharged through the nozzle to generate thrust. Its core design concept is to use superheated water as an energy storage medium to convert the input electrical energy into heat energy stored in the engine, thereby increasing the total temperature of the combustion gas and effectively improving the engine's specific impulse. This design not only improves the engine's efficiency but also reduces its environmental impact, and has broad application prospects.

[0003] Currently, existing thermoelectric rocket engines often require increased combustion chamber length or face problems with insufficient gas mixing during operation. This results in a short residence time of fuel gas inside the combustion chamber and insufficient mixing, causing some performance loss. Furthermore, under low-power conditions, uneven gas distribution leads to a sharp drop in performance. Therefore, an improved device is needed to address these issues. Summary of the Invention

At the bottom center of the body, the conveying pipe is fixedly installed at the bottom end of the second one-way valve, the rotary joint is rotatably installed on the side end of the conveying pipe near the second photoelectric sensor, the gear ring is fixedly installed on the outer ring of the rotary joint, the extension wing plate is fixedly installed at the bottom of the side end of the transfer cavity near the rotary joint, the hexagonal rod is slidably inserted into the inside of the extension wing plate, the rack is fixedly installed at the bottom end of the hexagonal rod, the return spring is fixedly installed between the extension wing plate and the rack, the connecting vertical plate is fixedly installed at the top end of the hexagonal rod, the alignment tube is fixedly installed at the bottom end of the rack, and the second solenoid valve is fixedly installed on the outer ring of the alignment tube.

[0008] Specifically, the support device includes a lead screw, a drive motor, a flow guide cavity, and a combustion chamber. The flow guide cavity is fixedly installed on the inner wall of the combustion chamber and is arranged in a ring shape. The drive motor is fixedly installed at the top center of the combustion chamber, and the lead screw is fixedly installed at the top center of the drive motor.

[0009] Specifically, the covering cavity is fixedly installed on the outer ring of the combustion chamber, the connecting rod is slidably inserted into the top of the transfer cavity, the horizontal plate is threaded onto the outer ring of the lead screw, the transfer cavity is fixedly installed on the top of the combustion chamber, and the transfer cavity is distributed in a ring shape, and the rack meshes with the gear ring.

[0010] Specifically, the contact ring is vertically aligned with the second solenoid valve, the guide tube and the covering cavity are in contact with the surfaces of the combustion chamber and the nozzle, and the alignment guide rod is vertically aligned with the connecting vertical plate.

[0011] Specifically, both the first and second photoelectric sensors are electrically connected to the first solenoid valve, the rotary joint is located at the top of the combustion chamber, the transfer chamber is hollow, and the transfer chamber, the second one-way valve, the delivery pipe and the rotary joint are interconnected.

[0015] The beneficial effects of this invention are:

[0016] First, this invention uses a rotary joint located at the top of the combustion chamber, with the rotary joint tilted at a certain angle and aligned with the inner wall of the combustion chamber. This allows the gas to rotate and flow along the inner wall of the combustion chamber when superheated water is injected, forming a vortex. This increases the residence time of the superheated water and improves the contact efficiency with the heat source, thereby absorbing energy more fully. Furthermore, through the combination of a first solenoid valve and a first one-way valve, superheated water can be replenished into the transfer chamber at any time to ensure complete combustion of the superheated water.

[0017] Second, this invention allows the piston to move downwards inside the transfer chamber, pressurizing the gas inside the transfer chamber and preventing the rotary joint from experiencing excessively low pressure. Simultaneously, as the piston moves, it causes the rotary joint to rotate within the combustion chamber, facilitating uniform gas flow within the combustion chamber. Furthermore, the guide chamber stabilizes the initial flow direction of the superheated water. The presence of three rotary joints ensures uniform delivery of superheated water within the combustion chamber, achieving a consistent distribution of superheated water. Attached Figure Description

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the vortex-enhanced thermoelectric hybrid rocket engine of the present invention includes a rocket shell 3. A flow guiding mechanism 1 is fixedly installed at the bottom end of the rocket shell 3, and the flow guiding mechanism 1 is arranged in a ring. A nozzle 2 is fixedly installed at the bottom end of the flow guiding mechanism 1. The flow guiding mechanism 1 includes a contact device 4 and a transmission component 5. The contact device 4 is fixedly installed at the bottom end of the transmission component 5. The contact device 4 includes a contact ring 6, a covering cavity 7, an air inlet pipe 8, and a flow guiding pipe 9. The flow guiding pipe 9 is fixedly installed at the bottom end of the covering cavity 7, and the flow guiding pipe 9 is arranged in a ring. The air inlet pipe 8 is fixedly installed on the outer ring of the covering cavity 7, and the air inlet pipe 8 is arranged in a ring. The contact ring 6 is fixedly installed on the top end of the air inlet pipe 8. The transmission component 5 includes a displacement device 10, an accumulation device 11, and a support device 12. The displacement device 10 is threaded onto the outer ring of the support device 12. The accumulation device 11 is fixedly installed on the top end of the support device 12, and the accumulation device 11 is arranged in a ring.

[0033] like Figure 5 The displacement device 10 includes a horizontal plate 13, an extension base frame 14, a connecting rod 15, a piston 16, and an alignment guide rod 17. The extension base frame 14 is fixedly installed on the outer ring of the horizontal plate 13 and is arranged in a ring. The alignment guide rod 17 is fixedly installed on the side end of the extension base frame 14 away from the horizontal plate 13. The connecting rod 15 is symmetrically fixedly installed on the bottom end of the extension base frame 14 near the alignment guide rod 17. The piston 16 is fixedly installed on the bottom end of the connecting rod 15. The horizontal plate 13 is threaded onto the outer ring of the lead screw 34, so that when the lead screw 34 rotates in both directions, it can drive the horizontal plate 13 to move up and down.

[0034] like Figure 6 and Figure 7The storage device 11 includes a first photoelectric sensor 18, a transfer chamber 19, a first solenoid valve 20, a first one-way valve 21, a second one-way valve 22, a delivery pipe 23, a rack 24, a second solenoid valve 25, an alignment pipe 26, a rotary joint 27, a gear ring 28, a connecting vertical plate 29, a second photoelectric sensor 30, a hexagonal rod 31, an extension wing plate 32, and a return spring 33. The second photoelectric sensor 30 is fixedly installed on the top side of the transfer chamber 19.

The second one-way valve 22 is fixedly installed at the center of the bottom of the transfer chamber 19. The delivery pipe 23 is fixedly installed on the second one-way valve. At the bottom of 22, a rotary joint 27 is rotatably mounted on the side end of the conveying pipe 23 near the second photoelectric sensor 30. A gear ring 28 is fixedly mounted on the outer ring of the rotary joint 27. An extension wing plate 32 is fixedly mounted on the bottom side end of the transfer cavity 19 near the rotary joint 27. A hexagonal rod 31 is slidably inserted into the inside of the extension wing plate 32. A rack 24 is fixedly mounted on the bottom end of the hexagonal rod 31. A return spring 33 is fixedly mounted between the extension wing plate 32 and the rack 24. A connecting vertical plate 29 is fixedly mounted on the top end of the hexagonal rod 31. An alignment tube 26 is fixedly mounted on the bottom end of the rack 24. A second solenoid valve 25 is fixedly mounted on the outer ring of the alignment tube 26. By setting up the conveying pipe 23 and the first one-way valve 21, gas can be prevented from flowing back from the inside of the first one-way valve 21 when the piston 16 squeezes the superheated water inside the transfer cavity 19.

[0035] like Figure 8 The support device 12 includes a lead screw 34, a drive motor 35, a flow guide cavity 36, and a combustion chamber 37. The flow guide cavity 36 is fixedly installed on the inner wall of the combustion chamber 37 and is arranged in a ring. The drive motor 35 is fixedly installed at the top center of the combustion chamber 37, and the lead screw 34 is fixedly installed at the top center of the drive motor 35. The flow guide cavity 36 is in contact with the inner wall surface of the combustion chamber 37, so that the initial flow direction of the superheated water can be stabilized.

[0036] The covering cavity 7 is fixedly installed on the outer ring of the combustion chamber 37. The connecting rod 15 is slidably inserted into the top of the transfer cavity 19. The horizontal plate 13 is threaded onto the outer ring of the lead screw 34. The transfer cavity 19 is fixedly installed on the top of the combustion chamber 37 and is arranged in a ring. The rack 24 meshes with the gear ring 28. The contact ring 6 is vertically aligned with the second solenoid valve 25. The guide pipe 9 and the covering cavity 7 are in contact with the surfaces of the combustion chamber 37 and the spray nozzle 2. The alignment guide rod 17 is vertically aligned with the connecting vertical plate 29. The first photoelectric sensor 18 and the second photoelectric sensor 30 are both electrically connected to the first solenoid valve 20. The rotary joint 27 is located at the combustion chamber 37. The interior top of the combustion chamber 37 and the interior of the transfer chamber 19 are hollow. The transfer chamber 19, the second one-way valve 22, the delivery pipe 23 and the rotary joint 27 are interconnected. A contact sensor is fixedly installed at the bottom of the second solenoid valve 25 and is electrically connected to the contact sensor. A sealing gasket is fixedly installed on the outer ring surface of the piston 16. The rotary joint 27 is vertically aligned with the top of the guide chamber 36. A round hole is opened at the top of the outer ring of the combustion chamber 37. A threaded hole is opened in the center of the interior of the horizontal plate 13. The outer ring surface of the piston 16 is in contact with the inner wall of the transfer chamber 19. A discharge hole is opened at the bottom of the guide pipe 9.

[0037] The working principle of Example 1 is as follows: During use, the alignment tube 26 can be connected to the gas transmission equipment inside the rocket engine. Simultaneously, the first one-way valve 21 can be connected to the superheated water supply equipment inside the rocket engine. Then, the drive motor 35 is turned on, causing the lead screw 34 to rotate. The horizontal plate 13 is threaded onto the outer ring of the lead screw 34, allowing the horizontal plate 13 to move downwards. When the extension base 14 moves downwards to contact the top of the second photoelectric sensor 30, the first solenoid valve 20 can be opened through the second photoelectric sensor 30. At this time, the superheated water can be discharged into the transfer chamber 19 through the first one-way valve 21. Then, the drive motor 35 is turned on, causing the lead screw 34 to rotate in the opposite direction, causing the horizontal plate 13 and the extension base 14 to move upwards. This allows the piston 16 to move upwards inside the transfer chamber 19, expanding its volume. At this point, superheated water can be stored inside the transfer chamber 19. Subsequently, when the piston 16 moves upwards to its limit position, it contacts the first photoelectric sensor 18. The first photoelectric sensor 18 acts as a power-off circuit, de-energizing the first solenoid valve 20 and preventing the first check valve 21 from continuously supplying superheated water into the transfer chamber 19. Then, the drive motor 35 is turned on, rotating the lead screw 34. This causes the cross plate 13 to move downwards, moving the piston 16 downwards inside the transfer chamber 19. This allows the superheated water inside the transfer chamber 19 to be discharged into the combustion chamber 37 through the delivery pipe 23 and the rotary joint 27. Combustion takes place internally. The rotary joint 27 is tilted at 30°, allowing superheated water to circulate and flow along the inner wall of the combustion chamber 37, increasing its residence time and ensuring complete combustion. When the piston 16 moves downwards, the alignment guide rod 17 moves to contact the connecting vertical plate 29. This causes the connecting vertical plate 29 to push the hexagonal rod 31 and rack 24 downwards simultaneously. The rack 24 moves downwards along the surface of the gear ring 28, causing the gear ring 28 and rotary joint 27 to rotate simultaneously. This allows the rotary joint 27 to rotate and fine-tune within the combustion chamber 37 until it rotates to 60°, ensuring even distribution of superheated water within the combustion chamber 37. The hexagonal rod 31 slides inside the extended wing plate 32, allowing the rack 24 to move vertically in a straight line. When the rack 24 moves downward to its limit position, the alignment tube 26 can be inserted into the intake pipe 8. Simultaneously, the contact sensor at the bottom of the second solenoid valve 25 can contact the contact ring 6, allowing the contact sensor to receive the sensing signal from the contact ring 6 and open the second solenoid valve 25. This allows airflow to enter the alignment tube 26, the cover cavity 7, and the guide tube 9. The cover cavity 7 and the guide tube 9 are respectively in contact with the outer surfaces of the combustion chamber 37 and the spray nozzle 2, enabling heat exchange and preventing the surface temperature of the spray nozzle 2 and the combustion chamber 37 from becoming too high. At the same time, when the rotary joint 27 delivers superheated water into the combustion chamber 37...With the rotary joint 27 positioned above the flow guide cavity 36 and its nozzle aligned with the flow guide cavity 36, superheated water can flow through the interior of the flow guide cavity 36. The flow guide cavity 36 stabilizes the initial flow direction of the superheated water. Subsequently, when the piston 16 moves downward to its limit position, the extension base 14 contacts the second photoelectric sensor 30, and the piston 16 does not contact the bottom of the transfer cavity 19. At this point, the extension base 14 contacts the second photoelectric sensor 30 again, opening the first solenoid valve 20 to deliver superheated water into the transfer cavity 19. Then, the drive motor 35 is activated, causing the lead screw 34 to rotate in the opposite direction, resulting in... When piston 16 moves upward to reset, the alignment guide rod 17 gradually disengages from the connecting vertical plate 29. The elasticity of the reset spring 33 causes the rack 24 to move upward, allowing the gear ring 28 to rotate the rotary joint 27 in the opposite direction to reset. Simultaneously, the alignment tube 26 can be pulled out from inside the intake pipe 8. The second solenoid valve 25 disengages from the contact ring 6, de-energizing it to prevent it from remaining in operation for an extended period. Subsequently, when the alignment guide rod 17 completely disengages from the connecting vertical plate 29, the reset spring 33 causes the rack 24 to move upward back to its original position, allowing it to rotate the gear ring 28 and rotary joint 27 again, completing the operation.

[0038] Example 2

[0039] Based on Example 1, such as Figure 9 As shown, the transfer chamber 19 also includes a conical chamber 38 and a flow meter 39. The conical chamber 38 is fixedly installed at the bottom center of the transfer chamber 19, and the flow meter 39 is fixedly installed at the bottom center of the conical chamber 38.

[0040] In implementing this embodiment, a conical cavity 38 is installed at the bottom end of the transfer cavity 19, and the bottom end of the conical cavity 38 is relatively narrow. When the piston 16 moves downward inside the transfer cavity 19, it can increase the pressure at the outlet of the conical cavity 38, thereby increasing the pressure of the superheated water discharged. Furthermore, the flow meter 39 is connected to the conical cavity 38, so that the specific value of the superheated water discharged from the transfer cavity 19 can be recorded, which facilitates the precise calculation of the superheated water consumption and the completion of the work.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
