Description

Technical Field

[0001] The present invention relates to the technical field of ammunition equipment, and in particular to an integrated ammunition design and use method and system. Background Art

[0002] Ammunition systems are responsible for terminal damage in war, determining the trajectory of warfare and changing the landscape of warfare. Rationally designing ammunition systems to fully utilize their destructive capabilities is a vital and ongoing requirement for national defense. While seemingly simple in structure, ammunition harbors numerous extreme challenges. For example, the warhead shell must withstand immense overload pressure during launch to determine whether it can meet strength requirements under this pressure. A projectile flies through the air at high speed, and even the slightest deviation in its center of mass or moment of inertia can cause it to lose accuracy or even fall. During the encounter between the projectile and the target, due to the high speeds of both sides, even a slight change in the intersection conditions can result in the projectile failing to kill the target or causing significant collateral damage. Due to the lack of mature integrated design methods, ammunition often has a long development cycle and high development costs. During battlefield use, due to a lack of familiarity with its operating principles and characteristics, its destructive power cannot be fully realized, resulting in wasteful use.

[0003] Currently, there is a lack of mature research on comprehensive ammunition design and employment systems, encompassing integrated ammunition design, damage assessment and ammunition decision-making, and simulation training systems. Existing ammunition design and employment systems are fragmented, making it difficult to implement a comprehensive cycle from ammunition design to use and optimization. Damage assessment system databases lack data, resulting in a lack of close connection between damage assessment results and actual combat, and a lack of effective linkage between damage assessment systems and combat command systems. The lack of ammunition simulation training systems makes it difficult for soldiers to grasp the working principles and characteristics of ammunition, resulting in an inability to fully unleash its destructive power.

[0060] The following is a brief introduction to the inventive concepts of the embodiments of this application.

[0061] Figure 1 According to the first embodiment of the present application, a workflow diagram of an integrated ammunition design and use method is shown, and the integrated ammunition design and use method includes the following steps:

[0062] Obtain the user's tactical and technical requirements and design the preliminary structure of the ammunition;

[0063] Analyze the performance indicators of the preliminarily designed ammunition and determine whether the ammunition meets the tactical and technical requirements;

[0065] Based on the constructed battlefield ammunition decision analysis plan, war scenarios are constructed, the destructive effects of ammunition on targets are simulated, and ammunition simulation training is carried out.

[0066] The present invention is demand-oriented and designs an ammunition database, which includes basic information of ammunition such as structural dimensions, weight, charge type, charge quantity, and propellant type; internal ballistic performance parameters such as firing chamber pressure and initial velocity; external ballistic performance parameters such as bullet shape coefficient, range, firing altitude, and shooting accuracy; terminal ballistic performance parameters of ammunition, such as mass distribution, velocity distribution, dispersion angle, airborne flight speed attenuation of damage elements, and propagation and attenuation of explosion shock waves, which can be used as input conditions for damage assessment and decision-making, transmitted to the damage assessment and decision-making strategy processing, and output a damage assessment report based on the target vulnerability and projectile-target intersection conditions set by the damage assessment and decision-making strategy, and determine the ammunition use decision based on the characteristics and damage requirements of the incoming target. By using visualization extension, users can view the projectile's internal ballistic launch range, external ballistic flight trajectory, terminal explosion shock wave field, and fragment dispersion field through simulation training based on the projectile designed by the integrated design subsystem and the calculated internal and external ballistic performance and terminal ballistic performance. Users can also combine damage assessment with decision-making strategies to select different ammunition and shooting conditions under given conditions such as the type and flight trajectory of the incoming target, view the damage effect on the target, and achieve the effect of simulation training.

[0067] Specifically, we will obtain the user's tactical and technical requirements and design the preliminary structure of the ammunition, which also includes:

[0068] Ammunition includes grenades and armor-piercing rounds;

[0069] The user's tactical and technical requirements include at least the range, accuracy, and power of the ammunition;

[0070] When the ammunition is a grenade, the preliminary structure of the ammunition design shall include at least the mass and filling ratio of the projectile, the overall length of the projectile, the diameter and wall thickness of the projectile, the length and radius of the head of the projectile, the length and angle of the stern, the projectile body and the charge material;

[0071] When the ammunition is an armor-piercing projectile, the preliminary structure of the designed ammunition includes at least the diameter of the projectile body, the length of the projectile body, the length of the head, the total length of the projectile body, the size and number of the annular teeth of the projectile body, the area of ​​the fins, the length of the fins, the thickness of the fins, the average chord length of the fins, the material of the projectile body and the sabot.

[0072] For armor-piercing shells and grenades, we conduct research on integrated ammunition design, integrating the parametric design of projectile geometry models, simulation and calculation of internal and external ballistic performance, and calculation of terminal damage power. We integrate CAD / CAE and database technologies and follow the principle of "design-analysis-optimization". In the design phase, we first determine the preliminary structure based on the tactical and technical demand indicators. Then, by analyzing its internal and external ballistics and terminal ballistic performance, we test whether the designed structure meets the established tactical and technical demand indicators. Based on the analysis results, we optimize the structure and enter the next design cycle until the designed product can meet or exceed the tactical and technical demand indicators.

[0073] Specific analysis of the performance indicators of the preliminary designed ammunition to determine whether the ammunition meets the tactical and technical requirements, including:

[0074] The performance indicators of ammunition shall at least include interior ballistic motion analysis, exterior ballistic performance calculation, and terminal damage power calculation;

[0075] Based on the results of interior ballistic motion analysis, exterior ballistic performance calculation, and terminal damage power calculation, determine whether the designed ammunition's muzzle velocity and chamber pressure, range, accuracy, and power meet tactical and technical requirements;

[0076] If the tactical and technical requirements cannot be met, the projectile structure dimensions will be modified and the next round of design will begin.

[0077] Furthermore, Figure 2A According to some embodiments of the present application, a detailed design roadmap for an integrated ammunition design and method of use is shown, which is a grenade integrated design route;

[0078] Structural design and material selection mainly consider the projectile mass and filling ratio, the total length of the projectile, the projectile diameter and wall thickness, the length of the warhead and the arc radius of the head, the length and angle of the stern, and the projectile and charging materials.

[0079] Internal ballistic motion analysis mainly includes calculating the projectile's muzzle velocity, the chamber pressure curve, and the velocity curve of the projectile's movement in the bore through the internal ballistic equation, based on the known gunpowder performance parameters, gun barrel length, chamber volume, gun caliber, projectile mass, and projectile movement starting pressure, and combining finite element analysis software to verify the launch intensity of the projectile's movement in the bore.

[0080] The calculation of exterior ballistic performance mainly involves first calculating the projectile's polar moment of inertia, equatorial moment of inertia, center of mass position, center of pressure position, projectile pressure center coefficient, and lift coefficient based on the projectile's mass and filling ratio, projectile's full length, projectile's diameter and wall thickness, projectile's head length and head arc radius, and stern length and angle. This is followed by obtaining the projectile's gyroscopic stability factor and following stability factor, and verifying the projectile's flight stability. The flight resistance of the projectile is calculated by combining the flight speed Mach number and the air flow Reynolds number. Then, the initial muzzle velocity of the projectile and the shooting angle are calculated based on the mass and diameter of the projectile, the bullet shape coefficient, and the internal ballistics. The range, speed, shooting height, and landing angle time course curve of the projectile flying in the air are obtained by solving the external ballistic equation. The external ballistic performance calculation also includes calculating the shooting accuracy of the projectile, including the landing point density and the target density, based on the aerodynamic inhomogeneity and mass inhomogeneity of the projectile, and considering the influence of muzzle nutation and windage.

[0081] The terminal damage power calculation takes into account the impact velocity and angle. Based on parameters such as projectile mass, diameter, and density, the projectile's explosion shock wave field, fragment mass distribution, and dispersion field are calculated. The density, thickness, and yield strength of the target material are combined to calculate the damage effect of the projectile's detonation on the target. Based on the results of the internal and external ballistics and terminal ballistics calculations, it is determined whether the designed projectile's muzzle velocity, chamber pressure, range, accuracy, and power meet the tactical and technical requirements. If not, the projectile's structural dimensions are modified and the next round of design is entered.

[0082] Specifically, damage analysis is performed on ammunition that meets tactical and technical requirements, a damage probability table is obtained, and a battlefield ammunition decision analysis plan is constructed, which also includes:

[0083] Build a conventional ammunition database and a typical target vulnerability database;

[0084] Calling the conventional ammunition database and the typical target vulnerability database, judging the missile-target intersection status based on the ammunition and target movement characteristics, the ammunition shooting accuracy and dispersion, and building a missile-target intersection judgment and damage assessment strategy;

[0085] According to the actual situation on the battlefield, the damage effects of different types of ammunition on targets under different shooting conditions are calculated, a damage probability table is made, the connection between shooting conditions and ammunition damage probability is established, and a battlefield ammunition damage assessment and auxiliary rapid decision-making plan is constructed.

[0086] Correspondingly, Figure 2B According to some embodiments of the present application, a detailed design roadmap for an integrated ammunition design and method of use is shown, which is an integrated design roadmap for armor-piercing projectiles;

[0087] The specific functions are: structural design and material selection, mainly considering the diameter of the projectile body, the length of the projectile body, the length of the head, the total length of the projectile body, the size and number of the projectile body ring teeth, the area of ​​the wing, the length of the wing, the thickness of the wing, the average chord length of the wing, the projectile body and the material of the sabot.

[0088] Internal ballistic motion analysis mainly includes calculating the projectile's muzzle velocity, the chamber pressure curve, and the velocity curve of the projectile's movement in the bore through the internal ballistic equation, based on the known gunpowder performance parameters, gun barrel length, chamber volume, gun caliber, projectile mass, and projectile movement starting pressure, and combining finite element analysis software to verify the launch intensity of the projectile's movement in the bore.

[0089] The calculation of external ballistic performance mainly involves first calculating the center of pressure coefficient and lift coefficient of the projectile body and tail fin based on structural parameters such as projectile body diameter, projectile body length, head length, total length of projectile body, wing area, wing length, wing thickness, and average chord length of wing, and then obtaining the stable reserve of the projectile and checking the flight stability of the projectile; calculating the flight resistance of the projectile based on the projectile body diameter, projectile body length, head length, head vertex angle, wing area, wing length, wing thickness, and average chord length of wing, combined with the flight speed Mach number and air flow Reynolds number, and then calculating the range, speed, shooting height, and landing angle time history curve of the projectile flying in the air based on the projectile mass and diameter, bullet shape coefficient, and the initial velocity of the projectile calculated by internal ballistics, and the shooting angle; the calculation of external ballistic performance also includes calculating the shooting accuracy of the projectile, including the landing point density and the target density, based on the aerodynamic inhomogeneity and mass inhomogeneity of the projectile, and considering the influence of muzzle nutation and windage.

[0090] The terminal damage power calculation takes into account the impact velocity and angle. Based on parameters such as projectile mass, diameter, and density, and the density, thickness, and yield strength of the target material, the projectile's maximum penetration velocity or depth is calculated. Based on the results of the internal and external ballistics and terminal ballistics calculations, it is determined whether the designed projectile's muzzle velocity, chamber pressure, range, accuracy, and power meet tactical and technical specifications. If not, the projectile's structural dimensions are modified and the next round of design is entered.

[0091] Furthermore, Figure 2C According to some embodiments of the present application, a detailed design roadmap for an integrated ammunition design and use method is provided, which is a damage assessment and ammunition decision-making design roadmap, including:

[0092] (A) Constructing a conventional ammunition database, (B) Analyzing typical target systems and structures, (C) Damage modes, levels, and damage criteria, (D) Establishing equivalent models, (E) Determining projectile-target encounters and damage assessment, and (F) Ammunition decision-making.

[0093] (A) Constructing a conventional ammunition database includes: collecting and calculating basic information about conventional air defense ammunition and entering it into the database, including basic information about the ammunition such as structural dimensions, weight, charge type, charge quantity, fuze type, and propellant type; internal ballistic performance parameters such as firing chamber pressure and initial velocity; external ballistic performance parameters such as projectile shape coefficient, range, altitude, and shooting accuracy; and calculating terminal ballistic performance parameters of the ammunition, such as the mass distribution of damage elements, velocity distribution, dispersion angle, airborne velocity attenuation, and the propagation and attenuation of the explosion shock wave.

[0094] Ammunition types include conventional natural fragmentation warheads, prefabricated and pre-controlled fragmentation warheads, cluster fragmentation warheads, and shaped charge and fragmentation combination warheads. The database has the functions of deletion, addition, modification and query.

[0095] (B) Analysis of typical target systems and structures includes determining the tasks and mission completion methods of typical air targets, systematically dividing them and functionally positioning them, conducting detailed research on the working principles of typical air targets based on a clear understanding of the target's combat information and basic composition, combining the serial completion of components and the parallel completion of some redundant designs or redundant switching design research to clarify the functional logical relationships between components and subsystems, between systems, and between systems and the whole.

[0096] Most of the aircraft's skin is pressed with aluminum alloy, and the front casing, aircraft frame, ribs, etc. are also mostly made of aluminum alloy; magnesium alloy is mainly used in engine casing, oil pumps and oil pipes, gearboxes, rocker arms, doors and rudders, etc.; aircraft engines, bulletproof parts, reinforced parts, reinforced parts, combustion chambers, turbine shafts, turbine discs, nozzles and other components are mostly made of titanium alloy; ultra-high strength steel is mainly used in starter frame components, engine shafts, etc.; in addition, for the sake of lightweight and protection needs, typical aerial targets often use a large number of polymer materials (such as rubber, nylon, polyethylene, polyurethane, polyimide, etc.), fiber-reinforced composite materials (such as carbon fiber epoxy resin composites, fiberglass, etc.), bulletproof ceramics, glass and other brittle materials; due to the particularity of the incoming target, it is usually also necessary to consider its propulsion system and the energetic materials carried by the warhead, such as propellants and explosives.

[0097] Therefore, it is necessary to collect and organize the elastic-plastic parameters of metal materials (aluminum alloys, stainless steel, high-strength steel, titanium alloys, etc.) under quasi-static loads, such as elastic modulus, Poisson's ratio, yield strength and tensile strength, strengthening coefficient, and impact toughness. This is in addition to commonly used strain-rate-dependent strength and failure model parameters such as the JONHSON-COOK strain rate, such as the hardening constant, strain rate coefficient, hardening exponent, and thermal softening index. For brittle materials such as ceramics and glass, the elastic modulus, tensile strength, and strain rate coefficient, as well as strength model parameters applicable to brittle materials such as the JOHNSON_HOLMQUIST_CERAMICS, should also be collected and organized.

[0098] Collect and organize the elastic modulus, Poisson's ratio, yield strength and tensile strength of fiber-reinforced composite materials (carbon fiber epoxy resin composites, fiberglass, etc.) in all directions, as well as commonly used damage criterion parameters such as the HASHIN criterion, PUCK criterion and CHANG-CHANG criterion.

[0099] Collect and organize the elastic modulus, Poisson's ratio, and yield strength of polymer materials (rubber, nylon, polyethylene, polyurethane, polyimide), as well as parameters of viscoelastic models and damage evolution models such as OGDEN and Zhu-Wang-Tang. Collect and organize parameters such as impact detonation pressure, explosion pressure, and explosion heat of energetic materials (propellants, explosives, etc.).

[0100] (C) Damage Modes, Levels, and Damage Criteria: This involves analyzing the damage modes of typical aerial targets, classifying damage levels, and determining damage criteria. For example, a missile's battlefield mission is to accurately guide the warhead to the target area and reliably detonate it in a timely manner to destroy the target.

[0101] The possible damage modes of missiles are: (1) failure to accurately fly to the target (yaw); (2) failure to detonate the warhead (dud); and (3) catastrophic damage (disintegration). The mechanisms that lead to these damage modes are very complex. For example, under the action of fragments or shock waves, the local compression, deformation, bending, and wing breakage and deformation of the missile body may cause asymmetry of aerodynamic forces and cause the missile to yaw. Damage to the seeker and control system, fuel leakage, engine failure, etc. can also cause the missile to fail to accurately fly to the target. Damage to the missile's fuse and detonation sequence may result in a dud. The damage level classification of missiles is shown in Table 1.

[0102] Table 1 Damage level classification

[0103]

[0104]

[0105] Regarding the damage criteria, first, at the physical level, the component-level damage phenomena under the action of the damage element, such as deformation, perforation, and fragmentation, are determined; then, at the functional level, the functional-level damage of the subsystem under the action of the damage element is determined, and the damage tree method and hierarchical analysis method are used to establish a quantitative relationship between the component damage caused by the damage element and the degree of subsystem function loss.

[0106] (D) Establishing equivalent models involves first targeting composite materials, polymer materials, ceramics, organic glass, and other materials, based on their deformation and damage characteristics under the action of damaging elements such as fragments, kinetic energy rods, jets, and EFPs. Using strength equivalence theory, residual penetration equivalence theory, and energy equivalence criteria, these materials are equated to common materials such as 2A12 aluminum alloy or 45 steel. The equivalent structures are then calibrated using numerical simulations and range testing.

[0107] For special-shaped structures such as ribbed reinforcement, plate and shell theory is used to calculate the effect of rib inclusions in the stiffened plate on the deformation of the entire plate under external forces, as well as the internal stress and strain distribution. Stress concentration during deformation is predicted, along with the initial location of failure and the corresponding conditions. Stress concentration factors are calculated to determine the equivalent mechanical properties of the overall structure in the primary deformation direction, and an equivalent material parameter model for the stiffened plate is established. For sandwich structures, stiffness theory is used to equate the sandwich plate to an isotropic shell of unequal thickness to the original sandwich plate. This shell can withstand both shear and bending moments perpendicular to the panel and in-plane pressure and shear, ensuring that the bending, planar, and shear stiffness of the equivalent plate are equivalent to those of the sandwich plate. For certain components with complex internal structures but low protection equivalence, equivalent target plates are designed using equivalent criteria such as impact energy, and the material and thickness of the equivalent target plate are established to withstand the same impact energy.

[0108] When equivalencing an entire critical component or subsystem, based on material equivalence, standard geometric solids such as cuboids and cylinders can be used to describe the geometric form of components with regular shapes and regular appearances. However, for analysis systems or components consisting of a large number of complex structures, it is difficult to approximate all components using standard geometric figures. Therefore, one or more "exclusive" equivalent geometric solids are redefined for certain representative and unique critical components.

[0109] (E) Projectile-target intersection judgment and damage assessment include projectile-target intersection parameters, including: ammunition parameters such as projectile velocity, yaw angle, and trajectory inclination; target parameters such as target velocity, yaw angle, and trajectory inclination; and intersection parameters such as projectile-target distance, target elevation angle, and target azimuth. Projectile-target intersection is simulated using the firing line technique and the Monte Carlo random method. The firing line technique uses firing lines with a certain number of identifiers, mass, velocity, origin, and azimuth to stochastically simulate the trajectory of a projectile or fragment and its intersection with the target. The intersection point coordinates and penetration path are determined based on the target's three-dimensional data. Key techniques in the ray tracing method include ray generation, deflection, bifurcation, and termination criteria. Ray generation refers to the penetration of a damaging element into the target, resulting in residual mass and residual velocity. Ray deflection refers to the deflection of a damaging element upon penetration at a certain angle of incidence. Ray bifurcation refers to the fragmentation of a damaging element or the generation of a fragment cloud during collision with the target, with each fragment representing a new ray. The termination of the ray indicates that the projectile or fragment cannot penetrate the target plate. During the calculation process, the first step is to determine whether the ray intersects with the target structure or component element. If so, the damage element has struck the target structure or component. Using the input geometric feature data of the target structure or component and following the coordinate transformation theory of analytic geometry, the ray is intersected with the plane or quadratic surface. This yields the coordinates of the impact point, impact angle, and impact time. The penetration equation is then used to determine whether the damage element can penetrate the target plate and its residual mass and residual velocity, which are then used to determine the generation and termination of the ray. The MONTE CARLO stochastic simulation method, based on mathematical statistics theory, approximates mathematical or physical problems through statistical experiments on random variables. It uses mathematical methods to generate random numbers with a known distribution. These numbers are then input into a mathematical model of unknown random variables determined by these random variables. The random numbers of the unknown random variables are then calculated, resulting in the statistical value of the distribution of the desired random variables. High accuracy can be achieved with a sufficient number of simulations.

[0110] Using the ray method and residual velocity calculations, the number of fragments penetrating each component is counted. The damage probability of each key component is then calculated based on the damage criteria. Probability calculations are performed based on the logical connections between key components in the damage tree. This means that the damage probability of each subsystem (intermediate event) is calculated from the damage probability of the key component (bottom event), and then the damage probability corresponding to each functional system or damage level (top event) is obtained.

[0111] According to the projectile speed, yaw angle, and ballistic inclination at the time of intersection, the exterior ballistic equation is used to solve the inverse calculation of the projectile's shooting condition information such as the initial shooting velocity and shooting angle, and the relationship between the shooting conditions and the damage probability is established, that is, a damage probability shooting table for a specific target is prepared. The shooting table content includes the target type, target attack parameters (including target speed, target yaw angle, target trajectory inclination), and the damage level and probability corresponding to different shooting conditions under the corresponding attack conditions.

[0112] (F) Ammunition decision-making involves inputting the target type and parameters (including target speed, target yaw angle, and target trajectory inclination) when an aerial target approaches. Based on the damage probability firing table, an ammunition usage plan is given, including the type of ammunition to be used (natural fragmentation warhead, prefabricated and pre-controlled fragmentation warhead, cluster fragmentation warhead, or shaped charge and fragmentation combination warhead), firing conditions (initial firing velocity and angle), and the required amount of ammunition.

[0113] Specifically, based on the constructed battlefield ammunition decision analysis plan, war scenarios are constructed, the damage effects of ammunition on targets are simulated, and ammunition simulation training is carried out, which also includes:

[0114] Construct war scenarios and set the types, numbers, and directions of incoming targets;

[0115] Import the types, numbers and directions of incoming targets into the target model;

[0116] Set different ammunition types, ammunition quantities and projectile-target intersection conditions, and simulate the damage effect of ammunition on the target in the form of desktop virtual display.

[0117] The above-mentioned simulation training of ammunition is a visual extension of the integrated ammunition design and use method. Users can design projectiles based on the integrated design method and calculate the internal and external ballistic performance and terminal ballistic performance. Through simulation training, users can view the projectile's internal ballistic launch range, external ballistic flight trajectory, and terminal explosion shock wave field and fragment dispersion field; they can combine damage assessment and decision-making strategies, and select different ammunition and shooting conditions under given conditions such as the type and flight trajectory of the incoming target to view the damage effect on the target and achieve the effect of simulation training.
