Description

Technical Field

[0001] This application relates to the field of aerospace technology, and in particular to a gel electric pump type self-generating pressurization supply system. Background Technology

[0002] Hydrogen peroxide gel rocket engines are one of the most studied types of rocket engines. Currently, they often use a squeeze-type propellant supply system, which is mainly achieved in two ways. One is to use gas (such as nitrogen or helium) stored in a high-pressure cylinder to provide pressurization pressure, and the other is to use an electric motor to drive a piston to provide pressurization pressure. The pressurization pressure then squeezes the gel propellant in the tank into the thrust chamber.

[0003] However, the extrusion-type gel propellant supply solution has the following obvious shortcomings: Firstly, gel propellants have higher requirements for the volume and weight of the extrusion supply solution. This is because gels have high viscosity, which leads to a higher pressurization pressure. Compared with commonly used liquid propellants, it requires a higher pressurization gas pressure stored in the cylinder and a greater extrusion pressure provided by the piston. This will cause a significant increase in the volume and weight of the pressurization components (cylinder, hydraulic cylinder, and extrusion piston). Secondly, the extrusion supply solution is difficult to apply to working environments with high thrust and long working time. This is because the volume and weight of the required pressurization components will increase significantly with the increase of thrust and working time.

[0004] Therefore, there is an urgent need for a gel electric pump-type self-generating pressurization supply system to solve, to some extent, the technical problems existing in the current technology. Summary of the Invention

[0009] In the above technical solution, the gel electric pump self-generating pressurization supply system further includes a heat exchanger;

[0010] The heat exchanger is located between the gas generator and the input end of the storage tank;

[0011] The heat exchanger can maintain the temperature of the water vapor and oxygen obtained by the decomposition of the gas generator at a preset cooling temperature.

[0012] In the above technical solution, the storage tank further includes a shell and a heat insulation plate;

[0013] The heat insulation plate is sealed within the housing perpendicular to the axis of the storage tank, thereby dividing the storage tank into a non-communicating pressurization chamber and a storage chamber for storing the hydrogen peroxide gel.

[0014] The water vapor and oxygen passing through the heat exchanger can be introduced into the pressurization chamber as pressurizing gas.

[0015] The pressurized gas can push the heat insulation plate to move in the first direction, compressing the volume of the storage cavity to increase the pressure of the hydrogen peroxide gel inside the storage cavity.

[0016] In the above technical solution, the shape and size of the heat insulation plate are adapted to the shape and size of the bottom of the storage tank, so that when the heat insulation plate moves to the bottom of the storage tank along the first direction, all the hydrogen peroxide gel in the storage cavity can be exported to the thrust chamber.

[0020] In the above technical solution, the gel electric pump self-generating pressurization supply system further includes a decomposition branch and an output branch;

[0022] The input end of the output branch is connected to the output end of the tank, and its output end is connected to the thrust chamber. The output branch is provided with a venturi tube and a solenoid valve in sequence from the tank to the thrust chamber.

[0023] In the above technical solution, the decomposition branch further includes a throttling coil and a diaphragm valve connected to the throttling coil;

[0024] The throttling coil is located near the heat exchanger, and the diaphragm valve is located near the storage tank.

[0025] In the above technical solution, the gel electric pump self-generating pressurization supply system further includes a condensation branch;

[0026] The input end of the condenser branch is connected between the gas generator and the pump body, and the output end is connected to the input end of the condenser tube of the heat exchanger. The output end of the condenser tube of the heat exchanger is connected to the output branch.

[0046] The following reference Figures 1 to 3 This application describes a gel electric pump-type self-generating pressurization supply system provided according to embodiments of the present application.

[0047] This embodiment provides a gel electric pump type self-pressurization supply system that can pressurize the tank 4 to push the propellant (the propellant is hydrogen peroxide gel) in the tank 4 into the thrust chamber 12.

[0048] Specifically, the gel electric pump self-pressurization supply system includes a storage tank 4 for storing hydrogen peroxide gel, a thrust chamber 12, and a gas generator 9.

[0049] At least a portion of the hydrogen peroxide gel in the storage tank 4 can be introduced into the gas generator 9, where it decomposes to produce water vapor and oxygen. This portion of water vapor and oxygen can act as pressurizing gas and be introduced into the storage tank 4, thereby pushing the remaining hydrogen peroxide gel in the storage tank 4 into the thrust chamber 12.

[0050] In summary, compared with the prior art, this application has a simple structure. It can decompose hydrogen peroxide gel into the required pressurized gas simply by using a gas generator. It can directly utilize the hydrogen peroxide gel stored in the storage tank 4 and decompose it into the required pressurized gas by the gas generator. It is essentially a self-sufficient method, without the need for an additional power source for pressurization. Therefore, it solves the technical problem of application limitations caused by the size and weight of the pressurization component in the prior art.

[0051] In this embodiment, the self-decomposition process of the hydrogen peroxide gel via the gas generator is exothermic. Water in the decomposition products absorbs heat and becomes water vapor. The boiling point of water increases with increasing pressure (e.g., the boiling point of water at 8 MPa is 296.35°C). Since the operating pressure of the storage tank 4 is generally much higher than standard atmospheric pressure, the temperature of the pressurized water vapor is often above 100°C. To ensure that the temperature of the pressurized water vapor and oxygen is suitable for the temperature of the storage tank 4 (i.e., the temperature should not be too high), in this embodiment, the gel electric pump self-pressurization supply system also includes a heat exchanger 11.

[0052] Specifically, the heat exchanger 11 is located between the gas generator 9 and the storage tank 4. The high-pressure, high-temperature steam and oxygen obtained by the gas generator will undergo heat exchange treatment through the heat exchanger 11, so that the temperature of the high-pressure steam and oxygen is reduced to a preset temperature, preferably 80°C.

[0053] In summary, in this embodiment, the heat exchanger 11 exchanges heat between high-temperature water vapor and oxygen, so that the temperature of water vapor and oxygen is suitable for the storage tank 4, thereby ensuring the effective operation of the storage tank 4 and preventing explosion accidents.

[0054] In this embodiment, considering that the hydrogen peroxide gel in the storage tank 4 has poor stability at high temperatures and is easily decomposed, and can easily react with water vapor and oxygen, in order to prevent the hydrogen peroxide gel in the storage tank 4 from reacting with water vapor and oxygen, in this embodiment, the storage tank 4 is designed to include two parts: a shell 200 and a heat insulation plate 400.

[0055] Specifically, the heat insulation plate 400 is sealed within the housing 200 perpendicular to the axis of the storage tank 4, so that the storage tank 4 is divided into a non-communicating pressurization chamber and a storage chamber for storing hydrogen peroxide gel.

[0056] Furthermore, the pressurization chamber is located above the storage chamber, allowing high-pressure water vapor and oxygen to be introduced into the pressurization chamber from the top of the storage tank 4.

[0057] Specifically, water vapor and oxygen can be introduced into the pressurization chamber as pressurizing gas through heat exchanger 11.

[0058] Furthermore, the pressurized gas can push the heat insulation plate 400 to move in a first direction, which refers to the vertical direction. That is, the pressurized gas can push the heat insulation plate 400 to move downward in the vertical direction. The downward-moving heat insulation plate 400 compresses the volume of the storage cavity, thereby increasing the pressure of the hydrogen peroxide gel in the storage cavity, and thus pushing the hydrogen peroxide gel in the storage tank 4 into the thrust chamber 12.

[0059] In summary, the heat insulation plate 400 separates the high-pressure water vapor and oxygen in the pressurization chamber from the hydrogen peroxide gel in the storage chamber, thereby preventing the high-pressure water vapor and oxygen from reacting with the hydrogen peroxide gel.

[0060] In this embodiment, the shape and size of the heat insulation plate 400 are adapted to the shape and size of the bottom of the storage tank 4, so that when the heat insulation plate 400 moves to the bottom of the storage tank 4 in the first direction, all the hydrogen peroxide gel in the storage cavity can be discharged to the thrust chamber 12.

[0061] Specifically, in combination Figure 2 As shown, the bottom of the storage tank 4 is curved towards the top, which can be understood as a concave structure. In this embodiment, the shape of the heat insulation plate 400 is also set to be curved towards the top of the storage tank 4. The bending angle of the heat insulation plate 400 is the same as the bending angle of the end of the storage tank 4 towards the top. When the curved heat insulation plate 400 moves to the bottom of the storage tank 4, it can completely overlap with the bottom, that is, it can push all the hydrogen peroxide gel in the storage cavity into the thrust chamber 12, thereby reducing the waste of hydrogen peroxide gel in the storage cavity.

[0062] Specifically, if the bottom of the storage tank 4 is a straight plate structure, that is, if the bottom of the storage tank 4 is parallel to the plane perpendicular to the axial direction of the storage tank 4, then the heat insulation plate 400 can also be set as a straight plate structure. When the heat insulation plate 400 of the straight plate structure moves to the bottom of the storage tank 4, it can completely overlap with the bottom, that is, it can push all the hydrogen peroxide gel in the storage cavity into the thrust chamber 12, thereby reducing the waste of hydrogen peroxide gel in the storage cavity.

[0063] Specifically, in this embodiment, the size of the heat insulation plate 400 (if the heat insulation plate 400 is a straight plate structure, then the size is the diameter) is set to the bottom size of the storage tank 4 because it is necessary to always ensure that the partition can separate two non-connected pressurization chambers and storage chambers.

[0064] In this embodiment, a sealing ring 300 is provided at the connection between the heat insulation plate 400 and the storage tank 4.

[0065] Specifically, the sealing ring 300 is used to enhance the sealing between the pressurization chamber and the storage chamber, preventing water vapor and oxygen in the pressurization chamber from flowing into the storage chamber through the gap between the heat insulation plate 400 and the side wall of the storage tank 4; thereby preventing hydrogen peroxide gel in the storage chamber from reacting with water vapor and oxygen.

[0066] In this embodiment, even though the heat exchanger 11 exchanges heat with the water vapor and oxygen obtained by the decomposition of the gas generator, so that the temperature is not so high, in order to further prevent the heat of the water vapor and oxygen with a preset temperature in the pressurization chamber from being transferred to the hydrogen peroxide gel in the storage chamber, two heat insulation plates 400 are provided in this embodiment.

[0067] Specifically, two heat insulation plates 400 are arranged at intervals along the axial direction of the storage tank 4, and a heat insulation space is formed between adjacent heat insulation plates 400. The heat insulation space can prevent the pressurized gas with a preset temperature in the pressurization chamber from transferring heat to the hydrogen peroxide gel in the storage chamber.

[0068] 1. It is worth noting that: in this embodiment, the number of heat insulation panels 400 is described as two. However, this application does not specifically limit the number of heat insulation panels 400. It can also be three, four, etc., depending on the actual situation.

[0069] In summary, this application employs a hollow structure (with an insulation space between adjacent insulation panels 400) to better suppress heat transfer. The insulation space can be filled with gas, and the gas interlayer can effectively increase the overall thermal resistance of the insulation panel 400, suppressing the heat transfer of high-temperature water vapor and oxygen to the hydrogen peroxide gel propellant.

[0070] In addition, the hollow structure of the insulation panel with a 400mm design can effectively reduce the structural weight, while the use of metal materials can ensure that the baffle will not undergo serious deformation.

[0071] In addition, to prevent the heat insulation plate 400 from flipping over, the thickness of the heat insulation plate 400 should be appropriately increased. If the inner diameter of the tank 4 is large and the thickness of the heat insulation plate 400 is small, the heat insulation plate 400 may flip over due to uneven stress or deformation, causing the hydrogen peroxide gel propellant to come into contact with high-temperature water vapor and oxygen. Therefore, appropriately increasing the thickness of the heat insulation plate 400 can effectively avoid the flipping problem.

[0072] In this embodiment, the gel electric pump self-generating pressurization supply system further includes a decomposition branch and an output branch.

[0073] Specifically, the bottom of the storage tank 4 is connected to the main road, on which a solenoid valve 1 is installed. The main road then splits into two branches, one of which is a decomposition branch and the other is an output branch.

[0074] Furthermore, the decomposition branch extends from the output end of the storage tank 4 to the input end of the storage tank 4 (here, the input end of the storage tank 4 refers to...). Figure 2 The gas interface 100 on the gas exchanger is provided with a pump body 6, a gas generator 9, a filter 10, a heat exchange tube of the heat exchanger 11, a throttling ring 14, and a diaphragm valve 15 in sequence.

[0075] Furthermore, the output branch is provided with a Venturi tube 13 and a solenoid valve 1 in sequence from the storage tank 4 to the thrust chamber 12.

[0076] More specifically, the gel electric pump self-generating pressurization supply system also includes a condensation branch; the input end of the condensation branch is connected between the gas generator 9 and the pump body 6 and the output end is connected to the input end of the condenser tube of the heat exchanger 11, and the output end of the condenser tube of the heat exchanger 11 is connected to the output branch.

[0077] In summary, the heat exchanger 11 has two pipes: a heat exchange tube and a condenser tube. During actual operation, heat exchange occurs between the condenser tube and the heat exchange tube, thereby cooling the high-temperature water vapor and oxygen. This application cleverly utilizes the condenser branch to directly introduce a portion of the undecomposed hydrogen peroxide gel into the heat exchanger 11 as a condenser, and after heat exchange is complete, it can be directly introduced into the thrust chamber 12.

[0078] In this embodiment, the gel electric pump self-generating pressurization supply system also includes a power unit; the power unit is capable of providing power to the pump body 6; the power unit includes a battery 8 and a first motor 7.

[0079] In this embodiment, an injection / discharge channel is also included, which can inject hydrogen peroxide gel into the storage tank 4, and an injection valve 5 is provided on the injection / discharge channel.

[0080] In this embodiment, a pressure sensor 3 is also provided between the storage tank and the solenoid valve. The pressure sensor is used to detect the pressure value on the main line in real time.

[0081] In this embodiment, the gas interface of the storage tank is also connected to a protection circuit, and a safety valve 2 is installed on the protection circuit.

[0082] In summary, the operational process of this application is as follows:

[0083] Initially, all valves are closed. During startup preparation, the injection valve 5 is opened, and propellant is injected into the storage tank 4 through the gel propellant injection / ejection channel. After injection, the injection valve 5 is closed, and a certain pressure is maintained in the storage tank 4.

[0084] Upon receiving the start-up command: the solenoid valve 1 between the storage tank 4 and the pump body 6 opens, and simultaneously the motor 7, powered by the battery 8, starts the pump body 6 to operate. Under pressure, the gel propellant in the storage tank 4 is squeezed out of the storage tank 4, with a portion entering the pump body 6 and the other portion entering the thrust chamber 12 after passing through the venturi tube 13.

[0085] The pressure of the gel propellant entering the pump body 6 is increased, and it splits into two paths after the pump. One path enters the gas generator 9, where the hydrogen peroxide gel propellant decomposes to produce water vapor and oxygen, which are used as pressurized gas. After being filtered by the filter 10 and cooled by the heat exchanger 11, it returns to the storage tank 4 through the throttle ring 14 and the diaphragm valve 15 while maintaining a gaseous state, thus keeping the storage tank 4 at its rated working pressure. The other path directly enters another inlet of the heat exchanger 11, where it is used as a coolant to cool the water vapor and oxygen used for pressurization. After leaving the heat exchanger 11, it enters the thrust chamber 12 through the venturi tube 13.

[0086] In summary, compared to the traditional extrusion-based supply scheme for gel propellants, this application employs a self-pressurizing supply scheme to supply hydrogen peroxide gel propellants. A portion of the gel propellant is drawn from the storage tank 4 via the pump body 6 and enters the gas generator 9. The propellant reacts in the gas generator 9 to produce high-temperature, high-pressure gas. This gas is then cooled by another portion of the propellant and enters the storage tank 4 for pressurization. This self-pressurizing supply scheme eliminates the need for large or heavy pressurizing structures such as high-pressure gas cylinders or motors 7 driving pistons, effectively reducing system weight. Furthermore, by using the pump body 6 and the gas generator 9 to generate pressurized gas, this structure effectively increases the output of pressurized gas, providing a higher pressurization pressure, thereby increasing the propellant supply flow rate and improving the thrust and operating time of the gel engine.

[0087] In addition, the self-pressurized supply scheme of this application can be applied to working scenarios that are difficult to meet by extrusion supply schemes, which allows the gel rocket engine to work with greater thrust and longer working time.

[0088] In addition, the tank 4 of this application can withstand pressurized gas at higher temperatures: the heat-insulated tank 4 structure of the high-temperature pressurized gas designed in this application can effectively suppress the heat transfer of high-temperature pressurized gas to the propellant and ensure a stable supply of hydrogen peroxide gel in the tank 4 during its own pressurization process.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
