Description

Technical Field

[0001] The present invention relates to the technical field of experimental research in high-temperature and high-speed gas dynamics, high-speed aircraft, etc., and more specifically, to a medium comprehensive management system for coaxial cylindrical deflagration drive technology. Background Art

[0002] A shock tube / wind tunnel is an experimental device widely used in the fields of high-temperature and high-speed gas dynamics, high-speed aircraft, etc. The basic principle is that a high-pressure driving gas compresses a low-pressure test gas through a shock wave to make it reach the required test state. As Figure 1 shown, a typical shock tube / wind tunnel includes a deflagration drive section 1', a driven section 2', a nozzle 3' and a test section 4'; before the test, the deflagration drive section 1' and the driven section 2' are separated by a diaphragm 5'. A high-pressure driving gas is filled in the deflagration drive section 1', and a low-pressure test gas is filled in the driven section 2'; during the test, the diaphragm 5' ruptures, the high-pressure gas expands and enters the driven section 2', and at the same time, a fast-moving shock wave is generated in the driven section 2'; if the gas after the shock wave is directly used for the test, the device operates in the shock tube mode; if the test gas accelerated by the nozzle 3' is used for the test, the device operates in the shock wind tunnel mode.

[0003] The total temperature and total pressure ranges of the test gas are the main indicators for measuring the capabilities of the device, and both depend on the driving ability of the high-pressure driving gas. Normal-temperature high-pressure gases can no longer meet the increasingly demanding test requirements. For this reason, three high-performance driving technologies have been developed at home and abroad: piston driving, heating light gas driving, and detonation driving. Among them, the detonation driving technology has the characteristics of low cost, simple structure, and relatively safe, and is the mainstream technology in China at present.

[0004] The detonation-driven shock tube was first proposed by Bird in 1957. Mr. Yu Hongru from the Institute of Mechanics, Chinese Academy of Sciences built a 13.3-meter-long detonation-driven shock tube in 1981, which was put into use in 1983. The Institute of Mechanics, Chinese Academy of Sciences developed the JF-10 detonation-driven high-enthalpy shock tunnel in 1994 [see the performance of the hydrogen-oxygen detonation-driven shock tunnel by Yu Hongru, Zhao Wei, and Yuan Shengxue - Aerodynamic Test and Measurement Control, 1993, 7(3): 38-42]. With the help of Mr. Yu Hongru, Gronig et al. built a high-enthalpy shock tunnel (TH2-D) using reverse detonation drive at RWTH Aachen University in Germany in 1993. In 1994, NASA modified the original free-piston drive design and built a forward detonation-driven high-enthalpy shock tunnel (HYPULSE) at GASL. This wind tunnel can operate in both reflected shock tunnel mode and expansion tube mode [see Chue RSM, Tsai C-Y, Bakos RJ, Erdos JI, Rogers RC (2002) NASA’s HYPULSE Facility at GASL - A Dual Mode, Dual Driver Reflected-Shock / Expansion Tunnel. In: Lu F, Marren D (eds), Advanced Hypersonic Test Facilities, Progress in Astronautics and Aeronautics, Vol. 198, AIAA, Chapter 3, pp29-71].

[0005] Detonation drive requires the formation of a detonation wave propagating axially in the deflagration drive section. The non-uniform flow field behind the detonation wave causes the following problems in this drive technology: First, the range of combustible gas mixing ratios is much narrower than that of deflagration, and the temperature and sound speed ranges of the drive gas are also correspondingly narrower. Therefore, it limits the total temperature range of the test gas that detonation drive can provide. Second, the effective drive pressure provided by detonation drive does not exceed 40% of the equipment's pressure-bearing limit, which limits the total pressure range of the test gas.

[0006] Due to the above problems with detonation drive, to overcome these problems, the coaxial cylindrical deflagration drive technology needs to be introduced. However, since the deflagration drive technology has strict requirements for the stability and purity of gas components, such as the generation of water vapor during the experiment, and water vapor will significantly reduce the pumping capacity of the pump, that is, the deflagration drive technology is very sensitive to water vapor, and the water vapor generated by combustion must be completely removed between two experiments.

[0007] The existing document 1 (106768802B) discloses a high-purity special gas filling device and filling method for a shock tunnel, which relates to the field of hypersonic shock tunnel engineering; it includes a vacuum pumping device, a special gas filling device, a measuring device, and a discharge pipeline; the vacuum pumping device, the special gas filling device, and the measuring device are respectively fixedly installed on the same side of the external shock tunnel gun barrel section, and the discharge pipeline is fixedly installed on the other side of the external shock tunnel gun barrel section; the vacuum pumping device includes a vacuum pump, a vacuum pump valve, a vacuum pump atmosphere connection valve, a vacuum corrugated hose, and a high-pressure pneumatic valve; among them, the intake port of the vacuum pump is fixedly connected to the vacuum pump valve and then divided into two pipelines, one of which is fixedly connected to the vacuum pump atmosphere connection valve, and the other pipeline is successively fixedly connected to the vacuum corrugated hose and the high-pressure pneumatic valve; the other end of the high-pressure pneumatic valve is fixedly connected to the external shock tunnel gun barrel section; the method for filling high-purity special gas by the special gas filling device is as follows: 1) Vacuum pumping: After pumping the pressure in the external shock tunnel gun barrel section to the required vacuum degree through the vacuum pumping device, close the high-pressure pneumatic valve and open the vacuum pump atmosphere connection valve to protect the vacuum pump; 2) Inflation: Reduce the special gas in the special gas cylinder to the required pressure through a pressure reducing valve, open the inflation valve, and close the inflation valve after filling to the test required pressure; 3) Measure the vacuum pressure: First, close the high-pressure atmosphere connection valve and the low-pressure atmosphere connection valve, and open the high-pressure pneumatic valve and the vacuum protection valve; when measuring the positive pressure, close the high-pressure atmosphere connection valve and the vacuum protection valve, and open the high-pressure pneumatic valve and the low-pressure atmosphere connection valve; before the shock tunnel runs, close the high-pressure pneumatic valve and the vacuum protection valve, and open the high-pressure atmosphere connection valve and the low-pressure atmosphere connection valve to protect the vacuum gauge and the low-pressure sensor from the influence of high-pressure gas during the test; 4) Exhaust: After the shock tunnel operation ends, open the pneumatic exhaust valve for exhaust; at the same time, the bypass exhaust hand valve can be manually opened for manual exhaust, but this device does not solve the above technical problems.

[0008] The prior art document 2 (CN102407947A) discloses a detonation double-drive device for a shock tunnel, comprising: a shock tunnel, which has a detonation deflagration drive section, with a detonation relief section provided at one end of the detonation deflagration drive section and a driven section provided at the other end; a first diaphragm is provided between the detonation relief section and the detonation deflagration drive section, and a second diaphragm is provided between the driven section and the detonation deflagration drive section; a forward detonation drive ignition device is provided in a section of the detonation deflagration drive section close to the detonation relief section, and a reverse detonation drive ignition device is provided in a section of the detonation deflagration drive section close to the driven section; a controllable delay trigger device is connected between the forward detonation drive ignition device and the reverse detonation drive ignition device, and the method is as follows: 1) A forward detonation ignition device is provided at one end of the detonation deflagration drive section of the shock tunnel close to the detonation relief section, and a reverse detonation drive ignition device is provided at one end of the detonation deflagration drive section close to the driven section; 2) Ignition is carried out through the forward detonation ignition device to form a forward drive detonation wave; 3) When the forward detonation wave propagates for a predetermined time along the detonation deflagration drive section, ignition is carried out through the reverse detonation drive ignition device to form a reverse drive detonation wave; 4) The reverse drive detonation wave tears the diaphragm provided between the driven section and the detonation deflagration drive section, and after the forward detonation wave intersects with the reverse detonation wave, a moving shock wave is formed, and this moving shock wave enters the driven section to compress the test gas in the driven section.

Start the low vacuum pump 307, and open all valves except the hot gas main valve 402, the high vacuum pump main valve 308, and the exhaust valve 501 to pump vacuum for the first gas supply pipeline 110, the second gas supply pipeline 206, the first vacuum pumping pipeline 310, the second vacuum pumping pipeline 311, the third vacuum pumping pipeline 312, the fourth vacuum pumping pipeline 313, the deflagration driving section 1, and the driven section 2. When the pressures of the pre-shock pressure gauge group 109 and the shock tube pressure gauge group 108 no longer decrease, close the low vacuum pump main valve 306, shut down the low vacuum pump 307, start the high vacuum pump 309, open the high vacuum pump main valve 308, and continue to pump vacuum until the pressures of the pre-shock pressure gauge group 109 and the shock tube pressure gauge group 108 no longer decrease. Close the high vacuum pump main valve 308 and shut down the high vacuum pump 309. Close the hot gas inlet valve 403, the deflagration driving section vacuum valve 301, the driven section vacuum valve 304, the post-shock vacuum valve 302 of the driving gas supply line, the pre-shock vacuum valve 303 of the driving gas supply line, the pre-shock vacuum valve 305 of the driven gas supply line, the post-shock valve 105 of the driving gas, and the post-shock valve 205 of the driven gas. Thus, the vacuum preparation is completed.

[0064] Open the first gas storage cylinder 101 and the second gas storage cylinder 201 of the driving gas, adjust the driving gas pressure reducer 103 and the driven gas pressure reducer 203 to make the value of the pre-shock pressure gauge group 109 meet the experimental requirements. Open the post-shock valve 105 of the driving gas and the post-shock valve 205 of the driven gas to fill the deflagration driving section 1 and the driven section 2 with gas. When the shock tube pressure gauge group 108 shows that the pressures of the deflagration driving section 1 and the driven section 2 reach the experimental required values, close the driving gas inlet valve 107, the post-shock valve 105 of the driving gas, and the post-shock valve 205 of the driven gas, and then close the first gas storage cylinder 101 and the second gas storage cylinder 201 of the driving gas. Thus, the gas filling is completed.

[0065] Ignite the deflagration drive section 1, let the driving gas burn, and conduct the experiment;

[0066] After the experiment, open the exhaust valve 501 to discharge the waste gas (especially water vapor) in the device; when the reading of the shock tube pressure gauge group 108 drops to atmospheric pressure, the exhaust is completed;

[0067] Separate the deflagration drive section 1 from the driven section 2, open the hot gas main valve 402 and the hot gas inlet valve 403, start the electric heating blower 401, so that the hot air enters from the left end of the deflagration drive section 1 and flows out from the right end of the deflagration drive section 1; when the water droplets on the wall of the deflagration drive section 1 are completely evaporated, the drying is completed.

[0068] As can be seen from the above embodiments, the medium comprehensive management system for coaxial cylindrical surface deflagration drive technology provided in this embodiment has at least achieved the following beneficial effects:

[0069] First, in this embodiment, a low vacuum pump and a high vacuum pump are used. The low vacuum pump is not only used to pump out the gas in the pipeline before the experiment, but also used to pump out the remaining water vapor after the experiment; by using it in combination with the high vacuum pump, the vacuum degree before the experiment is further guaranteed;

[0070] Second, the low vacuum pump and the high vacuum pump are both connected to the shock tube / wind tunnel and all pipelines in the coaxial cylindrical surface deflagration drive system, and can pump out the gas in all pipelines before the experiment starts, avoiding the problem of air mixing in the pipeline after a long time of stopping the experiment, and significantly improving the gas purity in the gas supply pipeline;

[0071] Third, by using the traditional gas filling method, the gases are mixed after entering the deflagration drive section respectively, and the mixing uniformity cannot meet the requirements of the deflagration drive technology. In this embodiment, an external mixer is used, so that the gases are fully mixed in the mixer first and then enter the deflagration drive section pipeline, effectively improving the gas mixing uniformity.

[0072] Optionally, continue to refer to Figure 2 As shown, the tail ends of the drying pipeline 404 and the first gas supply pipeline 110 are respectively connected to the head end of the deflagration drive section 1; the tail end of the first vacuum pumping pipeline 310 is connected to the tail end of the deflagration drive section 1; the tail end of the second gas supply pipeline 206 is connected to the head end of the driven section 2; in the present invention, the gas filling holes and the air extraction holes on the shock tube / wind tunnel are respectively located at both ends of the deflagration drive section 1 and the driven section 2. By adopting this scheme, compared with the random design of the positions of the gas filling holes and the air extraction holes in the existing traditional supply system, the air extraction dead angle is significantly reduced, the gas replacement efficiency is improved, and the mixing uniformity is improved.

[0073] Figure 3It is a schematic structural diagram of a blender provided by an embodiment of the present invention. Refer to Figure 3 As shown, the blender 106 includes a pipe body 1061. A wire 1062 extending along the conveying direction of the driving gas is arranged inside the pipe body 1061. The wire 1062 is a spiral wire, and the inner diameter of the pipe body 1061 is 8 - 12 mm.

[0074] Specifically, the blender 106 includes a pipe body 1061. A wire 1062 extending along the conveying direction of the driving gas is arranged inside the pipe body 1061. The wire 1062 is a spiral wire, and the material is stainless steel or copper wire. With this solution, the spiral wire can cause turbulence in the pipeline for the air flow, thereby strengthening the blending.

[0075] Optionally, continue to refer to Figure 3 As shown, the inner diameter of the pipe body is 8 - 12 mm.

[0076] Specifically, the inner diameter of the blender 106 affects the flow rate of the air flow. If the inner diameter is less than 8 mm, the air flow rate is too large, and if the inner diameter of the blender is greater than 12 mm, the air flow rate will be too small. Both too large and too small flow rates are not conducive to blending. Therefore, designing the inner diameter of the pipe body 1061 to be 8 - 12 mm can control the flow rate of the air flow within a suitable range, which is conducive to blending.

[0077] Figure 4 It is a schematic structural diagram of a coaxial cylindrical deflagration driving device for a shock tube / wind tunnel provided by an embodiment of the present invention; Figure 5 It is a schematic structural diagram of a coaxial cylindrical deflagration driving device for a shock tube / wind tunnel, excluding the medium comprehensive management system, provided by an embodiment of the present invention; Figure 6 It is Figure 5 The enlarged view of the structure at position B in Figure 7 It is Figure 4 The enlarged view of the structure of the discharge system in Figure 8 It is a logic block diagram of a discharge system provided by an embodiment of the present invention; Refer to Figure 4 - 8 As shown, a coaxial cylindrical deflagration driving device for a shock tube / wind tunnel provided in this embodiment further includes a deflagration driving section 1 and a driven section 2. One end of the deflagration driving section 1 is connected to the driven section 2, and the other end is connected to a blind plate 14. A diaphragm 5 is arranged between the deflagration driving section 1 and the driven section 2. The driven section 2 is connected to a test section 4 through a nozzle 3. The blind plate 14 is a flange cover. Using the blind plate 14 to block the end of the deflagration driving section 1 eliminates the need to use a traditional explosion relief section and a diaphragm between the explosion relief section and the deflagration driving section, which not only helps to reduce the occupied space area but also can reduce costs;

[0078] In the deflagration drive section 1, a first electrode 11 and a second electrode 12 extending radially along the Y direction are inserted. The first electrode 11 and the second electrode 12 have the same structure. The first electrode 11 is located on the side of the deflagration drive section 1 close to the blind plate 14, and the second electrode 12 is located on the side of the deflagration drive section 1 close to the driven section 2. That is to say, the first electrode 11 and the second electrode 12 are inserted at both ends of the deflagration drive section 1; An ignition wire 13 extending axially is electrically connected between the first electrode 11 and the second electrode 12. The axial direction X is the direction of the axis center line pointing from the blind plate 14 to the driven section 2, and the radial direction Y intersects with the axial direction X; Optionally, the ignition wire 13 can be made of any one of copper, silver, nickel-chromium, tungsten and alloys, and the length of the ignition wire 13 can be adjusted according to the length of the deflagration drive section 1;

[0079] The axial distance from the first electrode 11 to the blind plate 14 is L1, and the axial distance from the second electrode 12 to the diaphragm 5 is L2. If the lengths of L1 and L2 are less than 0.5 cm, breakdown may occur, resulting in equipment damage or endangering personnel safety; If the lengths of L1 and L2 are greater than 20 cm, it may cause unstable combustion of the combustible mixture in the deflagration drive section 1. Therefore, the lengths of L1 and L2 are limited to 0.5 cm - 20 cm. This not only makes the ignition wire 13 arranged axially in the deflagration drive section longer as much as possible, which can further make the combustible mixture in the deflagration drive section 1 burn more fully, but also can avoid the distances between the first electrode 11 and the end of the deflagration drive section and between the second electrode 12 and the diaphragm 5 from being too close, thereby avoiding breakdown and ensuring the safety of the equipment and personnel;

[0080] On the deflagration drive section 1, openings 8 are provided that cooperate with the first electrode 11 and the second electrode 12. Sealing rings 81 are provided on the contact surfaces of the first electrode 11 and the second electrode 12 with the openings 8. The opening 8 cooperates with the first electrode 11, and the second electrode 12 cooperates with the opening 8. Through the opening 8, it is convenient to insert the first electrode 11 and the second electrode 12 into the deflagration drive section 1;

[0081] The deflagration drive section 1 is filled with a combustible mixture. The combustible mixture can include fuel, oxidizer and inert gas. Among them, the fuel is hydrogen, carbon monoxide or alkene-alkyne hydrocarbons, or other combustible gases; The oxidizer is oxygen or nitrous oxide, or other oxidizing gases, and the inert gas is nitrogen, noble gas or carbon dioxide, or other gases that do not participate in the combustion reaction; The ratio of fuel:oxidizer:inert gas can be 1:1:1, the ratio of fuel:oxidizer:inert gas can also be 2:1:1, and the ratio of fuel:oxidizer:inert gas can also be 2:1:7. Of course, the ratio relationship among the fuel, oxidizer and inert gas is set according to the specific equipment and experimental requirements;

[0082] It further includes a discharge system 7, which includes a high-voltage capacitor 71, an ignition switch 720, and a discharge switch 730. The high-voltage capacitor 71 can generate a high voltage of 2000V. The positive electrode of the high-voltage capacitor 71, the ignition switch 720, the first electrode 11, the ignition wire 13, the second electrode 12, and the negative electrode of the high-voltage capacitor 71 form an ignition circuit 72; the positive electrode of the high-voltage capacitor 71, the discharge switch 730, and the negative electrode of the high-voltage capacitor 71 form a discharge circuit 73. The ignition circuit 72 and the discharge circuit 73 are connected in parallel. The high-voltage capacitor 71 is used to store high-voltage electricity;

[0083] After the high-voltage capacitor 71 is charged, first close the ignition switch 720. The high-voltage capacitor 71 is respectively conducted with the ignition wire 13 through the first electrode 11 and the second electrode 12 to start ignition. After a predetermined time, close the discharge switch 730 to short-circuit the positive and negative electrodes of the high-voltage capacitor 71. The charge in the high-voltage capacitor 71 will instantaneously return to the high-voltage capacitor 71 via the discharge circuit 73 to complete discharge. The above-mentioned predetermined time can be 5 - 30 milliseconds;

[0084] It further includes a medium comprehensive management system, which is the above-mentioned medium comprehensive management system for coaxial cylindrical deflagration driving technology, including a driving gas supply system, a driven gas supply system, a vacuum pumping system, a drying system, and an exhaust gas emission system. Its structure and working principle have been elaborated in detail above and will not be repeated here.

[0085] The working principle is as follows: There is an ignition wire 13 arranged along the axial direction X in the deflagration driving section 1. After the high-voltage capacitor 71 is charged, first close the ignition switch 720. The high-voltage capacitor 71 is respectively conducted with the ignition wire 13 through the first rotating electrode 11 and the second electrode 12. A high voltage of thousands to tens of thousands of volts is applied across both ends of the ignition wire 13. At the moment when the ignition switch 720 is powered on, the ignition wire 13 heats up violently and ignites the combustible mixture near the ignition wire 13 within a microsecond time scale. After ignition, a columnar flame front is formed and expands radially; by making the ignition wire 13 strictly coaxial with the pipeline of the deflagration driving section 1, it is ensured that the combustion is completed simultaneously at all axial positions; since the discharge process of the high-voltage capacitor 71 is longer than the combustion process, it is necessary to discharge the remaining charge in the high-voltage capacitor 71 before the end of combustion. Therefore, when a predetermined time has elapsed, close the discharge switch 730 to short-circuit the positive and negative electrodes of the high-voltage capacitor 71. The charge in the high-voltage capacitor 71 will instantaneously return to the high-voltage capacitor 71 via the discharge circuit to complete discharge, thereby preventing the breakdown of the combustion products near the positive electrode of the high-voltage capacitor 71 and causing safety accidents.

[0086] It should be noted that: Detonation driving requires the formation of a detonation wave propagating along the axial direction in the deflagration driving section, while deflagration driving is to simultaneously ignite the gas in the pipeline of the deflagration driving section 1 along the axial direction, complete combustion in a deflagration rather than detonation manner, and end combustion simultaneously along the axial direction X.

[0087] Generally, the effective working time of a shock tube / wind tunnel is roughly in the order of a few milliseconds to 100 milliseconds. To provide precise test conditions, it is necessary to strictly ensure that the combustible mixture in the deflagration driver section ignites simultaneously and burns out simultaneously.

[0088] As can be seen from the above embodiments, the coaxial cylindrical deflagration driving device for a shock tube / wind tunnel provided by the present invention has at least achieved the following beneficial effects:

[0089] First, in the prior art, a detonation wave propagating axially is formed in the deflagration driver section by detonation driving. Since the extremely high pressure peak of the detonation wave cannot all be used for driving, the effective pressure provided by detonation driving is much lower than the pressure-bearing limit of the device. In the present invention, deflagration replaces detonation, there is no pressure peak in detonation, and the combustion pressure can be 100% used to compress the test gas, thus increasing the pressure of the test gas.

[0090] Second, the mixture ratio limit of deflagration is much wider than that of detonation, the temperature and sound speed range of the driving gas is larger, and the corresponding total temperature range of the test gas is also larger than that of detonation driving.

[0091] Third, through the medium comprehensive management system, the stringent requirements for the stability and purity of gas components in deflagration driving technology can be met, and the water vapor generated by combustion can be completely removed between two experiments.

[0100] Of course, without considering the discharge of the high-voltage capacitor to the ignition wire, the above assembly sequence can be appropriately adjusted. After installing the driven section 2 or the blind plate 14, the discharge system can be connected first, and then the medium comprehensive management system 1000 can be installed on the deflagration drive section 1 and the driven section 2. Finally, the deflagration drive section 1 is filled with the combustible mixture, and the driven section 2 is filled with gas or air, as follows:
