Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multivariate comprehensive measurement, and particularly relates to a weather modification rocket bomb three-explosion self-destruction body assembly detection system. BACKGROUND

[0002] The weather modification rocket bomb is the core equipment of rain enhancement and hail prevention operation, and its safety and reliability directly determine the operation effect and the safety of ground personnel and property. The self-destruction body assembly quality is a key link to ensure that the residual debris after the operation of the rocket bomb is in compliance (≤100g) and to avoid ground risks. At present, the assembly of the self-destruction body of the rocket bomb in the industry mainly relies on manual operation and simple tools. The coaxiality and fitting pressure of the self-destruction body and the engine shell in the assembly process lack precise control, and the problem of excessive positioning deviation of the self-destruction body often occurs, which leads to uneven distribution of residual debris after self-destruction, and the weight of part of the residual debris exceeds the safety threshold, increasing the risk of injury to ground personnel.

[0003] In the self-destruction body agent filling link, the existing detection means mainly stays at manual weighing and visual inspection, and cannot accurately measure the agent filling density and internal defects. Uneven agent density will lead to unbalanced self-destruction energy release, and part of the area will have incomplete self-destruction due to low agent density, forming large mass residual debris. Defects such as holes and cracks in the agent will cause local energy concentration, which may cause early explosion accidents. In addition, there is a lack of systematic detection of the environmental adaptability of the self-destruction body after assembly in the industry. In the storage and use environment of -20℃ to 50℃, the agent is easy to absorb moisture and form lumps due to changes in temperature and humidity, and the connection part of the self-destruction body is easy to loosen due to material thermal expansion and cold contraction, leading to self-destruction efficiency decay, which is difficult to meet the reliability requirements of 3 years of storage period.

[0004] Although there are some single parameter detection devices in the current industry, there is a lack of integrated measurement system integrating positioning, agent, connection strength and igniter performance. The data of each detection link is independently stored, and it is impossible to realize multi-parameter correlation analysis and self-destruction efficiency prediction. The detection process relies on manual recording and data comparison, which is not only low in efficiency, but also easy to cause data tampering and omission, leading to unqualified products flowing into the market. At the same time, the detection equipment lacks a regular calibration mechanism, and the accuracy of the sensor decreases with the use time, further affecting the reliability of the detection data, which is difficult to support quality control in the process of large-scale production of rocket bombs, and cannot meet the market demand of doubling the demand for rain enhancement and hail prevention rocket bombs in the next 5-10 years.

[0064] Five, Data Representation and Interpretation

[0065] Table 1: Comparison of 56 mm rocket three-explosive self-destruction body assembly measurement indicators

[0066]

[0067] Table 1 shows that traditional single-device measurement has significant shortcomings: the coaxiality deviation of the self-destructing device is 0.45mm, exceeding the acceptable threshold, which can easily lead to imbalance in the self-destructing device's positioning and affect the uniform release of energy during self-destruction; the internal defect identification rate of the agent is only 82%, which may miss internal voids or cracks, leading to the risk of premature detonation; the connection strength measurement error is ±3.5%, making it difficult to accurately judge the reliability of the connection; the ignition delay measurement accuracy is ±0.05s, and excessive deviation can easily lead to disordered self-destruction timing; the self-destruction effectiveness prediction accuracy is 65%, often resulting in rework after assembly and increasing production costs. This system, through the collaborative work of multiple modules, controls the coaxiality deviation of the self-destructing device within the acceptable range of 0.25mm, increases the agent defect identification rate to 99%, reduces the connection strength measurement error to ±0.08%, optimizes the ignition delay measurement accuracy to ±0.01s, and achieves a self-destruction effectiveness prediction accuracy of 98%, effectively preventing unqualified products from entering subsequent processes. At the same time, the system reduces manual operation, shortening the assembly and measurement time of a single rocket from the traditional 40 minutes to 15 minutes, significantly improving production efficiency and meeting the needs of large-scale production.

[0068] Example 2: Assembly and Measurement of the Triple Destruction Body of a 44mm Rain-Enhancing and Hail-Suppressing Rocket

[0069] This embodiment is applied to the assembly and testing of the three-explosion self-destruct body of a 44mm rain-inducing and hail-suppressing rocket. The target product has a diameter of 44mm, a length of 750mm, and a total weight of 1.3kg. The three-explosion self-destruct body is adapted to the engine casing structure. After self-destruction, the weight of the debris is required to be ≤100g. The system achieves full parameter measurement, and the process is as follows.

[0070] I. Positioning and Drug Filling Measurement

[0071] A 44mm engine housing is fixed to an adjustable positioning fixture of a multi-dimensional positioning measurement module. The fixture is adapted to the 44mm outer diameter of the housing via a mechanical structure. Three sets of laser displacement sensors are arranged along the housing axis, with a scanning frequency of 1000Hz and a scanning accuracy of 0.01mm. The sensors collect real-time coaxiality data between the self-destructing head and the housing axis, with a measured value of 0.28mm, and an acceptable allowable value of ≤0.3mm. A piezoelectric pressure sensor embedded in the self-destructing head assembly station has a range of 0-200N and a resolution of 0.1N, and measures a contact pressure of 58N, which is within the acceptable range of 50-80N. During the chemical filling measurement, the weight measurement unit used a weighing sensor with an accuracy of 0.01g to weigh the self-destructing explosive cartridges of the three-explosive self-destruct device: the head cartridge was designed to weigh 20g, and the actual measured weight was 19.9g, a deviation of 0.5%; the middle cartridge was designed to weigh 22g, and the actual measured weight was 22.1g, a deviation of 0.45%; the tail cartridge was designed to weigh 21g, and the actual measured weight was 20.9g, a deviation of 0.48%. All deviations were ≤2% of the allowable value. The density measurement unit measured the chemical filling thickness using an ultrasonic thickness gauge and calculated the filling density based on the cartridge volume. The head cartridge volume was 42cm³.3 , middle cartridge volume 45 cm 3 , tail cartridge volume 43 cm 3 , the average density of the propellant is calculated to be 1.15 g / cm 3 , the design standard density is 1.17 g / cm 3 , the deviation is 1.2%, and the allowable range is ≤±3%. The defect detection unit starts the micro-focus X-ray flaw detector, the focus size is 5 μm, and the cartridge is scanned, and no defects ≥0.1 mm are found, and the propellant filling quality is qualified.

[0072] II. Connection strength and igniter measurement

[0073] In the connection strength measurement, the torque measurement unit uses a torque wrench with an accuracy of ±1% to apply a preset torque to the threaded connection between the three explosive self-destruction bodies, and the design value is 18.3 N·m. The preset torque is 1.2 times the design value, and the specific value is 22 N·m. The measured torque attenuation is 0.9 N·m, and the attenuation rate is 4.1%, which is ≤5% of the allowable value. The tension measurement unit applies an axial tension to the connection part of the self-destruction body and the shell through a tension testing machine, and the tensile strength is measured to be 3800 N, and the design value is 3900 N. The qualified value requires ≥95% of the design value, and the specific value of 95% of the design value is 3705 N. 3800 N≥3705 N, which meets the requirements. The vibration displacement measurement unit uses an electromagnetic vibration table to simulate the launch vibration environment. First, run in sine vibration mode, vibration frequency 45 Hz, acceleration 180 m / s 2 , duration 0.5 s; then run in random vibration mode, vibration frequency 10-1800 Hz, acceleration power spectral density 0.01 g 2 / Hz, the frame rate of the high-speed camera is set to 1200 fps, the displacement of the connection part is recorded, and the maximum value is 0.18 mm, and the allowable displacement is ≤0.2 mm. In the igniter performance measurement, the resistance measurement unit uses an ohmmeter with an accuracy of ±0.01 Ω to detect the resistance of the self-destruction double insurance igniter, and the reading is 0.65 Ω, which is within the qualified range of 0.55-1.0 Ω; The time measurement unit records the delay time through the time sequence recorder, and the timing accuracy of the time sequence recorder is 0.9 μs, and the average of 3 measurements is 0.9 s. The design value is 0.85 s, and the deviation is 5.9%. After adjusting the igniter terminal, the deviation is reduced to 4.8%, which is ≤5% of the allowable value; The safety reliability measurement unit simulates accidental impact through a drop hammer impact testing machine, with an impact force of 500 N and an action time of 10 ms. After impact, the multimeter detection shows that the safety mechanism is locked normally, and there is no accidental firing.

[0074] III. Self-destruction efficiency and environment measurement

[0075] In the self-destruction efficiency correlation measurement, based on the propellant filling density and connection strength data, the maximum residual mass prediction value after self-destruction is calculated through the self-destruction efficiency correlation formula, which is . Wherein is the total mass of the three-detonation self-destruction body and the corresponding shell part, taking the value 0.6 kg; is the performance correlation coefficient, taking the value 0.88, determined according to the number of three self-destruction cartridges; is the actual filling density of the agent, taking the value 1.15 g / cm 3 ; is the design standard density of the agent, taking the value 1.17 g / cm 3 ; is the actual connection strength, taking the value 3800 N; is the design standard value of the connection strength, taking the value 3900 N. Substituting the calculation is =0.6×(1-0.88×(1.15 / 1.17)×(3800 / 3900))=0.6×(1-0.88×0.983×0.974)=0.6×(1-0.847)=0.6×0.153=0.0918 kg=91.8 g, meeting the requirement of ≤100 g. After the environmental adaptability measurement module simulates a 50℃ high temperature and 90% RH humidity environment for 48 hours through an environmental test chamber, the agent filling mass and the connection strength are measured again: the head cartridge mass is 19.8 g, 19.9 g before the test; the middle cartridge mass is 22.0 g, 22.1 g before the test; the tail cartridge mass is 20.8 g, 20.9 g before the test; the connection strength is 3720 N, 3800 N before the test. The parameter attenuation rate is calculated using the environmental impact formula, which is . Wherein the middle cartridge mass is selected as 22.0 g, the middle cartridge mass is selected as 22.1 g, the value is 3720 N, the value is 3800 N, and the calculation is =1-(22.0×3720) / (22.1×3800)=1-(81840) / (84000)=1-0.974=0.026=2.6%, ≤5% of the allowable attenuation rate.

[0076] Four, data representation and explanation

[0077] Table 2: Comparison of assembly measurement indicators of 44 mm rocket three-detonation self-destruction body

[0078]

[0079] In Table 2: The data shows that the traditional single device measurement has many shortcomings in the assembly of 44mm rocket projectiles: the fitting pressure fluctuation is ±8N, the fluctuation range is too large, which easily leads to uneven assembly of the self-destruction body, affecting the separation accuracy of the self-destruction; the propellant density measurement deviation is ±4.2%, which exceeds the allowable range, which may cause imbalance of self-destruction energy release, leading to excessive debris; the displacement after vibration is 0.35mm, which exceeds the qualified threshold, increasing the risk of falling off of the self-destruction body during flight; the ignition device resistance measurement error is ±0.08Ω, which is too large and easily leads to abnormal ignition of the ignition device; the performance retention rate after the environment is only 88%, which is difficult to meet the reliability requirements of 3 years of storage. The system cooperates with multiple modules through high-precision sensors to reduce the fitting pressure fluctuation to ±1.5N, control the propellant density measurement deviation to ±1.2%, reduce the displacement after vibration to 0.18mm, optimize the ignition device resistance measurement error to ±0.02Ω, and improve the performance retention rate after the environment to 97.4%, which fully guarantees the assembly quality. At the same time, the system realizes automatic integration and traceability of data, avoids manual recording errors, reduces the unqualified rate of 50 rocket projectiles per batch from 12% to 1%, greatly reduces production costs, and improves production efficiency.

[0080] Referring to Figure 2 : The figure directly presents the stability of the self-destruction effect of the self-destruction body of the two caliber rocket projectiles. From the data, it can be seen that the weight of the debris of each batch of 44mm and 56mm rocket projectiles is controlled within the range of 88-98g, which is far lower than the technical requirement of ≤100g, and the weight fluctuation range between different batches of the same caliber is small (the maximum fluctuation of 44mm is 7g, and the maximum fluctuation of 56mm is 7g). This shows that the segmented explosive design and integrated sealing structure of the three-explosive self-destruction body have achieved remarkable results, which can ensure that the rocket projectiles of different calibers and different batches achieve lightweight after self-destruction, avoid the safety risk caused by excessive debris, and at the same time, reflect the consistency of the self-destruction structure in mass production, providing data support for the safety of artificial weather modification operations.

[0081] Referring to Figure 3 : The figure reflects the combustion stability and interior ballistic performance of the double-base propellant of the 56mm rocket projectile engine. From the data, it can be known that during the combustion period of 0.2-1.0s, the interior ballistic pressure of the engine is always stable within the range of 5.4-5.5MPa, which is highly consistent with the initial equilibrium pressure and the final equilibrium pressure (both are 5.5MPa) of the design, without obvious fluctuation. This is due to the single-hole tubular explosive double-base propellant design of the engine charge, which ensures uniform burning rate through internal and external combustion, and cooperates with the precise adjustment of the nozzle throat diameter to effectively control the pressure change during combustion. Stable interior ballistic pressure not only ensures the launch speed and flight stability of the rocket, but also provides a stable power basis for the separation of the self-destruction body, the scattering of the catalyst, etc., avoiding abnormal operation of the function parts due to pressure fluctuation.

[0082] Referring toFigure 4 : The figure reflects the environmental adaptability of the self-destruction delay system of the rocket projectile. The document requires the self-destruction time to be controlled within the range of 24±2.5s. From the data, it can be seen that even if the environmental temperature changes greatly from -20℃ (low temperature extreme) to 50℃ (high temperature extreme), the self-destruction delay time always maintains in the interval of 23.9-25.8s, fully meeting the technical requirements, and the deviation from 23.9s at normal temperature (25℃) is extremely small (the maximum deviation is 1.9s). This is due to the low hygroscopicity and high stability characteristics of the black powder and boron / potassium nitrate ignition powder used in the self-destruction delay igniter, combined with the heat insulation protection of the glass cloth structure of the adiabatic tube, effectively resisting the influence of temperature change on the burning rate of the delay agent, ensuring that the rocket projectile is accurately controllable in timing when operating in different regions and seasons, avoiding premature or late self-destruction due to delay abnormalities.

[0083] Referring to Figure 5 : The figure shows the connection reliability of the overall full-wrapped design of the three-explosive self-destruction body. From the data, the tensile strength of each independent part (head, middle, tail) and the connection (head-middle, middle-tail) of the self-destruction body is in the interval of 3900-4200N, the strength is balanced, and there is no obvious weak link. This is due to the combined connection method of thread + adhesive used in the three-explosive self-destruction body, the thread ensures the mechanical connection strength, the adhesive fills the gap and enhances the sealing, and at the same time, the integrated structure reduces the risk of fire leakage. Adequate and balanced connection strength can ensure that the self-destruction body does not fall off or loosen during the flight of the rocket projectile, until the preset timing triggers the self-destruction action, avoiding premature separation of the self-destruction body due to connection failure, further ensuring the flight stability and self-destruction reliability of the rocket projectile.

[0084] Referring to Figure 6 : The figure reflects the synergy of the rocket projectile shooting height and the catalyst scattering effect, among which the maximum shooting height of the 56mm rocket projectile is 7.5km, corresponding to the maximum catalyst scattering amount of 180g (meeting the technical indicators of the document). From the data, with the shooting height increasing from 4km to 7.5km, the catalyst scattering amount shows a steady increasing trend, and the higher the shooting height, the closer the scattering amount to the maximum value. This is directly related to the design advantage of the two-stage engine structure - after the first-stage engine breaks through the low-altitude resistance, the second-stage engine accelerates efficiently at medium and high altitudes, providing conditions for the full scattering of the catalyst in higher clouds (areas that need rain enhancement and hail prevention operation more). At the same time, the orderly change of the scattering amount with the shooting height indicates that the combustion and scattering function part and the timing control of the second-stage engine are accurate, which can dynamically adjust the scattering amount according to the flight altitude, ensuring that the catalyst can be efficiently covered in different altitude regions, improving the effect of weather modification operation.
