Description

Technical Field

[0001] This invention belongs to the field of countermeasures technology, and in particular relates to a method and system for deploying portable smoke grenade devices. Background Technology

[0002] In modern air defense operations, to maximize the concealment effectiveness of smoke screens, it is necessary to deploy smoke-generating equipment in advance. Existing smoke grenade equipment used to counter electro-optical guided weapons and various observation and aiming weapons is designed for plains operations. However, due to the significant differences in environmental conditions between high-altitude and plains areas, and the fact that electro-optical passive jamming equipment typically uses smoke screens to counter its targets, it is highly dependent on the environment. Commonly used vehicle-mounted smoke-generating equipment cannot meet the requirements. Therefore, there is an urgent need to study the practical application methods of portable smoke grenades in typical scenarios of smoke grenade use in high-altitude areas.

[0003] Existing research on smoke grenade air defense deployment largely applies analytical geometric analysis and numerical analysis algorithms to deployment models. This approach first analyzes the three-dimensional spatial parameters of the smoke grenade deployment scenario, then uses analytical geometry to construct a calculation model for the spatial scale of the vertical smoke screen. Mathematical derivation and Newton's descent method are then applied to build a calculation model for a single-point vertical smoke screen deployment. Using single-point smoke screen deployment as the unit and spatial smoke screen requirements as the final standard, a multi-point vertical smoke screen deployment calculation model is established. This allows for the calculation of parameters such as smoke screen requirements and deployment locations, thus completing the research on smoke grenade deployment methods. However, existing methods do not consider the influence of actual equipment launch distances, wind speed, wind direction, and other actual environmental parameters. Summary of the Invention

[0043] The simulation module is used to acquire the air temperature, atmospheric pressure, fluid density, wind speed and wind direction of the application scenario in order to simulate the smoke deposition and diffusion process in the application scenario and obtain the smoke concentration field, smoke deposition velocity field and pressure field in the application scenario.

[0044] The first calculation module is used to calculate the equivalent diameter of the smoke screen, the smoke formation time, and the smoke duration of each smoke grenade explosion in the application scenario based on the smoke concentration field, the smoke settling velocity field, and the pressure field, using the Lambert-Beer law.

[0047] The determination module is used to determine the deployment position of each smoke launcher in each batch and the number of smoke grenades launched in each batch based on the equivalent diameter of the smoke screen, the explosion distance of the smoke grenades, the parameters of the enemy's observation and aiming equipment, and the parameters of the protected area.

[0048] The calibration module is used to calibrate the launch azimuth angle of each smoke grenade launcher in each batch based on the wind speed, wind direction, parameters of the enemy's observation and aiming equipment, parameters of the protected area, the equivalent diameter of the smoke screen, the smoke formation time, and the deployment position of each smoke screen launcher.

[0049] Furthermore, when the application scenario is a mobile infiltration support scenario, the determining module includes:

[0050] The first calculation submodule is used to calculate the first distance between the target observation device and the protected area based on the position in the target observation device parameters and the protected area parameters.

[0051] The first determining submodule is used to determine the smoke grenade launching method based on the first distance and the smoke grenade detonation distance;

[0054] The third calculation submodule is used to calculate the number of smoke grenades launched in each batch based on the length of the protected area parameters, as well as the first distance, the second distance, the smoke grenade detonation distance, and the equivalent diameter of the smoke screen.

[0064] In summary, the technical solution of the present invention has the following technical effects:

[0065] This invention simulates the smoke settling and diffusion process using air temperature, atmospheric pressure, fluid density, wind speed, and wind direction in actual combat scenarios. The resulting smoke concentration field, smoke settling velocity field, and pressure field are more realistic. It can obtain smoke extinction performance (such as equivalent smoke diameter, smoke formation time, and smoke duration) under different wind speeds and ground roughness. Using the smoke duration and the total protection time of the protected area, it calculates the number of smoke grenade launch batches. Furthermore, it utilizes the equivalent smoke diameter, smoke grenade detonation distance, enemy observation and aiming equipment parameters, and protected area parameters. The method determines the number of smoke grenades to be launched in each batch and the deployment location of each smoke grenade launcher in each batch. By using wind speed, wind direction, enemy observation and aiming equipment parameters, protected area parameters, equivalent smoke diameter, smoke formation time, and the deployment location of each smoke grenade launcher, the launch azimuth angle of each smoke grenade launcher in each batch is corrected. This ensures the accuracy of the deployment of portable smoke grenade equipment and the effectiveness of countermeasures, fully utilizes the maximum concealment effect of smoke, improves the application level of portable smoke grenade equipment in high-altitude areas, and provides a strong basis for commanders' decision-making.

[0068] Figure 2This is a schematic diagram showing the positional relationship between the smoke screen area, the smoke grenade launcher, and the protective area of ​​the present invention. Detailed Implementation

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] This embodiment provides a method for deploying a portable smoke grenade device, referencing... Figure 1 The deployment method for this portable smoke grenade device includes the following steps:

[0071] S1. Obtain the air temperature, atmospheric pressure, fluid density, wind speed, and wind direction of the application scenario to simulate the smoke deposition and diffusion process in the application scenario, and obtain the smoke concentration field, smoke deposition velocity field, and pressure field in the application scenario.

[0072] The application scenarios in this embodiment include mobile infiltration support scenarios, passage control scenarios, and key point air assault scenarios.

[0073] The mobile infiltration support scenario in this embodiment is one of the main application scenarios for portable smoke grenade equipment. The infiltration area in this scenario is uninhabited, and strategic points such as passes and forks along the way are occupied by enemy snipers. Their optical reconnaissance equipment can easily detect our true operational intentions, and their light weapons pose a serious threat. To successfully pass through dangerous areas, our smoke grenade launchers accompany the infiltration team. When the infiltration team reaches the vicinity of the exposed area (i.e., the protected area), based on the distance and direction of the enemy's observation and aiming equipment and light weapons, as well as the length of the exposed area (i.e., the protected area), the number of smoke grenades to be launched, the launch direction, and the launch interval are quickly determined. The smoke grenade launcher is set up, and the launch controller is manually operated to create a smoke-covered corridor, disrupting the enemy's individual weapon aiming conditions. Under the cover of the smoke, the infiltration team quickly passes through the exposed area (i.e., the protected area).

[0074] In this embodiment, the passage control scenario, such as a typical mountainous environment, is characterized by extremely treacherous terrain and complex passage environments, stretching for tens or even hundreds of kilometers. Some important protected areas (such as passes, outposts, and command posts) are often key points contested by both sides and are highly susceptible to being targeted by the enemy. Protecting important passes and outposts within the passage is an important task of the smoke-generating equipment. The target is the enemy's laser semi-active guided weapon. Due to the limited terrain at the passes, command vehicles (posts) can be used to defend against precision strikes. Command vehicles are generally Mengshi vehicles, which are used for mobile command. If vehicle passage is inconvenient at the passes, the command post can also be in the form of a tent, with an area generally not exceeding 30 square meters.

[0075] The key scenario for preventing airborne landings in this embodiment is as follows: In high-altitude areas with harsh climates, extremely difficult transportation, and poor living conditions, transport helicopters become an important means of transportation. Although they have the advantage of being able to take off and land anywhere, landing in non-airport environments requires a sufficiently large site, aerial visibility, and a flat ground. Once these conditions are disrupted, landing is impossible. When enemy reinforcement helicopters are detected approaching our outposts / outposts, portable smoke grenade devices are used to launch smoke grenades into nearby airborne landing areas (i.e., protected areas) to obscure the terrain and disrupt the pilots' ability to obtain necessary landing information, thus preventing enemy reinforcement helicopters from conducting airborne landings near the conflict zone.

[0076] This embodiment performs geometric modeling of the space where the smoke screen diffuses (e.g., a three-dimensional space 50 meters long, 10 meters wide, and 20 meters high, i.e., a spatial geometric model). Utilizing the k-ε turbulence model (including the turbulent kinetic energy equation and the turbulent dissipation rate equation), a particle deposition model characterizing the motion of smoke particles, and fluid dynamics methods, combined with environmental parameters from different application scenarios (e.g., air temperature, atmospheric pressure, fluid density, wind speed, and wind direction), the OpenFOAM platform is used to simulate the smoke screen settling and diffusion process in the application scenarios, obtaining physical quantities such as the smoke concentration field, smoke settling velocity field, and pressure field in the application scenarios. In this embodiment, the airflow in the environment where the smoke screen is located is an incompressible fluid.

[0077] S2. Based on the smoke concentration field, smoke settling velocity field, and pressure field, and using the Lambert-Beer law, calculate the equivalent diameter of the smoke screen, the smoke formation time, and the smoke duration generated by the explosion of each smoke grenade in the application scenario.

[0078] This embodiment utilizes the above simulation results (i.e., smoke concentration field, smoke settling velocity field, and pressure field) and combines them with Lambert-Beer's law to calculate the infrared extinction area of ​​the smoke produced by each smoke grenade explosion under different conditions (in the application scenario), and determines the smoke extinction performance (such as the equivalent diameter of the smoke, the smoke formation time, and the smoke duration) under different wind speeds and different ground roughness.

[0079] S3. Calculate the number of smoke grenade launch batches based on the duration of the smoke screen and the total protection time of the protected area.

[0080] The number of smoke grenade launch batches in this embodiment is:

[0081]

[0082] Where, n 批 The number of smoke grenade launches; t 需 The total protection time for the protected area; t c The duration of the smoke screen.

[0083] S4. Obtain the parameters of the target observation and aiming equipment, the parameters of the protected area, and the smoke grenade detonation distance in the application scenario.

[0084] In this embodiment, the parameters of the target observation and aiming equipment include position and azimuth angle, and the parameters of the protected area include position, length and width.

[0085] S5. Based on the equivalent diameter of the smoke screen, the explosion distance of the smoke grenade, the parameters of the enemy's observation and aiming equipment, and the parameters of the protected area, determine the deployment position of each smoke screen launcher in each batch and the number of smoke grenades launched in each batch.

[0086] In this embodiment, the specific process of determining the deployment location of each smoke launcher in each batch includes:

[0087] Step S511: Based on the position in the parameters of the enemy observation and aiming equipment and the protected area, determine the center of the smoke area formed by each batch of smoke grenades located between the enemy observation and aiming equipment and the protected area;

[0088] Step S512: Based on the center of the smoke area formed by each batch of smoke grenades and the smoke grenade detonation distance, construct a circular area;

[0089] Step S513: Deploy the central smoke grenade launchers of each batch on the arc line of the circular area to determine the deployment position of the central smoke grenade launchers of each batch;

[0090] The central smoke grenade launcher is deployed close to the protected area and outside the line connecting the enemy's observation and aiming equipment and the central position, as well as its extension.

[0091] Step S514: Determine the deployment positions of the remaining smoke grenade launchers in each batch based on the pre-set distance between the smoke grenade launchers in each batch and the deployment position of the central smoke grenade launcher in each batch.

[0092] In this embodiment, when the application scenario is a mobile infiltration support scenario, the process of determining the number of smoke grenades to be launched in each batch includes:

[0093] Step S521: Calculate the first distance between the target observation device and the protected area based on the position in the target observation device parameters and the protected area parameters;

[0094] Step S522: Determine the smoke grenade launching method based on the first distance and the smoke grenade detonation distance.

[0095] The smoke grenade launching methods in this embodiment include accompanying launch, close-range launch, and rearward launch.

[0096] Step S523: Calculate the second distance between the protected area and the central smoke grenade launcher based on the deployment location and smoke grenade launching method of each batch of central smoke grenade launchers;

[0097] When using accompanying launch, the central smoke grenade launcher for each batch is generally set up near the two ends of the protected area, i.e., the local launch point. Launching smoke grenades from this location (i.e., the local launch point) can cover the infiltration unit as it passes through the protected area, and the amount of smoke grenades consumed is less than the amount of smoke grenades carried.

[0098] When using close-range firing, the smoke grenade launcher moves from the local firing point toward the enemy's observation and aiming equipment to a certain point (i.e., the position of the central smoke grenade launcher in each batch of smoke grenade launchers). When the distance between the certain point (i.e., the position of the central smoke grenade launcher) and the enemy's observation and aiming equipment is slightly greater than the maximum blast distance of the smoke grenade, and the required number of smoke grenades to be launched meets the firing requirements, smoke grenades can be launched to cover the infiltration team's safe passage through the protected area.

[0099] When using a rearward firing method, the smoke grenade is moved from the local firing point away from the enemy's observation and aiming equipment to a certain point (i.e., the position of the central smoke grenade launcher of each batch of smoke grenades). When the distance to the central smoke grenade firing point is slightly greater than the minimum blast distance of the smoke grenade, the smoke grenade can be fired to cover the infiltration team as they safely pass through the protected area.

[0100] In this embodiment, the smoke grenade detonation distance is located between the maximum and minimum detonation distances of the smoke grenade.

[0101] Step S524: Calculate the number of smoke grenades launched in each batch based on the length, first distance, second distance, smoke grenade explosion distance, and equivalent diameter of the smoke in the parameters of the protected area.

[0102] When the launch method is accompanying launch, the number of smoke grenades launched in each batch during a mobile infiltration support scenario is:

[0103]

[0104] Where n is the number of smoke grenades launched in each batch during the maneuvering and infiltration support scenario; L is the length of the protected area; L0 is the equivalent diameter of the smoke screen produced by each smoke grenade; R is the first distance between the enemy's observation and aiming equipment and the protected area; and R0 is the smoke grenade detonation distance.

[0105] When the launch method is close-range launch, the number of smoke grenades launched in each batch during a mobile infiltration support scenario is:

[0106]

[0107] Where n is the number of smoke grenades fired in each batch during the maneuvering and infiltration support scenario; L is the length of the protected area; L0 is the equivalent diameter of the smoke screen produced by each smoke grenade; R is the initial distance between the enemy's observation and aiming equipment and the protected area; R0 is the smoke grenade detonation distance; R D This is the second distance for close-range launch methods.

[0108] When the launch method is a rearward launch method, the number of smoke grenades launched in each batch during a mobile infiltration support scenario is:

[0109]

[0110] Where n is the number of smoke grenades to be fired in each batch during the maneuvering and infiltration support scenario; L is the length of the protected area; L0 is the equivalent diameter of the smoke screen produced by each smoke grenade; R is the initial distance between the enemy's observation and aiming equipment and the protected area; R0 is the smoke grenade blast distance; R h This is the second distance for the rearward launch method.

[0111] In this embodiment, when the application scenario is a channel control scenario, the process of determining the number of smoke grenades to be launched in each batch includes:

[0112] Step S531: Calculate the first distance between the target observation device and the protected area based on the position in the target observation device parameters and the protected area parameters;

[0113] Step S532: Based on the first distance and the smoke grenade detonation distance, determine the position of the smoke area between the enemy's observation and aiming equipment and the protected area;

[0114] Step S533: Determine the length and width of the smoke screen area based on its location and the length and width parameters of the protected area.

[0115] Step S534: Determine the third distance between adjacent smoke bombs in the same batch based on the equivalent diameter of the smoke screen;

[0116] Step S535: Calculate the number of smoke bombs launched in each batch based on the length and width of the smoke area and the third distance.

[0117] In this embodiment, the number of smoke grenades launched in each batch during the passage control scenario is:

[0118]

[0119] Where n is the number of smoke grenades launched in each batch in the passage control scenario; W and H are the width and length of the smoke area generated by the explosion of each batch of smoke grenades, respectively; and R′ is the third distance between the smoke screens generated by adjacent smoke grenades in the smoke area.

[0120] In this embodiment, when the application scenario is a key point air assault scenario, the process of determining the number of smoke grenades to be launched in each batch includes:

[0121] Step S541: Determine the third distance between the smoke screens generated by adjacent smoke bombs in the same batch based on the equivalent diameter of the smoke screen;

[0122] Step S542: Calculate the number of smoke bombs launched in each batch based on the length, width and third distance in the protected area parameters.

[0123] The key point in this embodiment is the number of smoke grenades launched in each batch during the anti-airborne landing scenario:

[0124]

[0125] Where n is the number of smoke grenades fired in each batch in the key air assault scenario; a and b are the width and length of the smoke area generated by the explosion of each batch of smoke grenades, respectively; and R′ is the third distance between the smoke screens generated by adjacent smoke grenades in the smoke area.

[0126] S6. Based on the wind speed, wind direction, parameters of the enemy's observation and aiming equipment, parameters of the protected area, as well as the equivalent diameter of the smoke screen, the smoke formation time, and the deployment position of each smoke screen launcher, the launch azimuth angle of each smoke screen launcher in each batch is corrected.

[0127] In this embodiment, the specific process of correcting the launch azimuth angle of each smoke grenade launcher in each batch includes:

[0128] Step S61: Determine the third distance between the smoke screens generated by adjacent smoke bombs in the same batch based on the equivalent diameter of the smoke screen;

[0129] Step S62: Calculate the included angle between adjacent smoke bombs in the same batch based on the deployment position of each smoke launcher in each batch and the third distance and smoke bomb explosion distance.

[0130] In this embodiment, the included angle between adjacent smoke bombs in the same batch is:

[0131]

[0132] Where Δβ is the angle between adjacent smoke grenades in the same batch; R′ is the third distance; R″ is the pre-set distance between smoke grenade launchers in each batch; and R0 is the smoke grenade detonation distance.

[0133] Step S63: Determine the launch azimuth of each smoke grenade launcher in each batch based on the azimuth and included angle in the parameters of the target observation and aiming equipment.

[0134] A triangle is formed by the center point D of the smoke screen area created by each batch of smoke grenades, the central smoke grenade launch point A1, and the protected area O, as shown below. Figure 2 As shown, calculate the launch azimuth angle of the central smoke grenade launch point A1:

[0135] ∠AOD = 360° - (α0 - α1);

[0136] Wherein, ∠AOD is the azimuth angle of the launch point A1 (i.e., the central smoke grenade launcher); α0 is the angle between the line connecting the center point D of the smoke area and the protected area O along the clockwise direction and the due north direction, which is the azimuth angle in the parameters of the enemy's observation and aiming equipment; α1 is the angle between the extension of the line connecting the protected area O and the central smoke grenade launch point A1 along the clockwise direction and the due north direction.

[0137] Based on the distances between smoke grenade launchers A2 and A3 relative to the central smoke grenade launcher A1, the angle between adjacent smoke grenades in the same batch is added to the launch azimuth of the central smoke grenade launch point A1 (i.e., the central smoke grenade launcher) to obtain the launch azimuth of smoke grenade launchers A2 and A3. The calculation method for the launch azimuth of each smoke grenade launcher at points B and C is the same.

[0138] Step S64: Calculate the offset distance of the smoke screen along the wind direction based on the wind speed and the smoke formation time.

[0139] In this embodiment, the offset distance of the smoke screen along the wind direction is:

[0140] ΔS=v F ·t x ;

[0141] Where ΔS is the offset distance of the smoke screen along the wind direction; v F For wind speed; t x The time it takes for the smoke screen to turn into smoke.

[0142] Step S65: Based on the azimuth, wind direction, offset distance, and smoke grenade detonation distance in the parameters of the target observation and aiming equipment, calculate the correction value of the launch azimuth caused by the wind direction, so as to correct the launch azimuth of each smoke grenade launcher in each batch.

[0143] In this embodiment, the correction value for the launch azimuth angle caused by wind direction is:

[0144]

[0145] Where Δα is the correction value of the launch azimuth angle caused by wind direction; ΔS is the offset distance of the smoke screen along the wind direction; α0 is the azimuth angle in the parameters of the enemy's observation and aiming equipment (i.e., the angle between the line connecting the center point of the smoke screen area and the protected area in the clockwise direction and the due north direction); α F R0 is the angle between the wind direction and due north; R0 is the smoke grenade detonation distance.

[0146] This embodiment simulates the smoke settling and diffusion process based on actual combat scenarios, considering air temperature, atmospheric pressure, fluid density, wind speed, and wind direction.
