Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of large-scale integrated killing and blasting warhead, and relates to a dynamic power test method of large-power multifunctional non-blind area killing and blasting warhead. BACKGROUND

[0002] The large-power multifunctional non-blind area killing and blasting warhead destroys or damages enemy heavy troops, command and control centers, communication hubs and radar stations in the form of fragment impact kinetic energy, shock wave overpressure and other damage elements; suppresses or damages enemy transportation hubs, ports, helicopter landing pads and airfields; suppresses or destroys enemy living forces and technical weapons and other various targets, and is a large-scale integrated killing and blasting warhead with large killing power, wide coverage and multiple damage targets. As the final damage unit of a missile weapon system, the large-scale integrated killing and blasting warhead usually uses a fuze to initiate high-energy explosives at the right time when the missile and the target meet, so as to form a blast shock wave and high-speed fragments under super-high-speed conditions to attack the target. In the evaluation of the damage power of the warhead, a dynamic power test is usually used to simulate the damage effect of the killing and blasting warhead under the condition of a certain explosion height and falling speed. The traditional method is to arrange target plates at different radii of the explosion center to form an effective killing area, so as to obtain the equivalent killing radius and complete the damage effect evaluation of different killing and blasting warheads.

[0003] The large-power multifunctional non-blind area killing and blasting warhead adopts a relatively complex damage element design in the design, and arranges perforated alloy beads and two or more different sizes of tungsten alloy balls in the front, middle and rear sections of the warhead according to the damage criteria of various targets, with a total number of fragments exceeding 100,000. At the same time, the warhead structure and fragment size arrangement are optimized and designed to maximize the fragment scattering angle and scattering direction angle, increase the fragment scattering range, and the dense killing range in the typical target area exceeds 30,000 m 2 , which puts higher requirements on the dynamic damage power evaluation of the warhead. When the traditional test method faces a larger fragment scattering range, the farther from the explosion center, the more target plates are needed, and the human, material and time costs of the test are greatly increased. At the same time, the target plate type, size, arrangement position and angle and other evaluation factors are relatively single, and the real damage situation of the warhead to different targets in different ranges cannot be accurately evaluated. Therefore, how to realize the dynamic power test verification of the warhead is one of the key technologies to solve the warhead power evaluation. SUMMARY

[0029] The present invention provides a dynamic power test method for a large-power multi-functional non-blind-zone killing and blasting warhead. Within the range of 0 to 180°, with a "meter" - shaped layout as the layout feature, within the layout range of 160 m from the explosion center, the radial interval distance of the target plates is 5 to 10 m, and every 45° circumferentially, 3 mm, 5 mm Q235 steel targets + cotton quilts, 15 mm armor steel and 20 mm pine wood targets are respectively arranged. The target plates do not block each other and are arranged with the aiming point as the center of the circle, and different angles with the ground are arranged according to the distance from the explosion center to ensure perpendicular incidence between the fragments and the target.

[0030] The following gives specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations made on the basis of the technical solution of this application fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] As Figure 1 shown, this embodiment provides a dynamic power test method for a large-power multi-functional non-blind-zone killing and blasting warhead, which can accurately verify the comprehensive damage power of a large killing and blasting warhead. The method takes the explosion center as the origin, the course direction is set as 0°, the counterclockwise direction is the positive angle, and the clockwise direction is the negative angle. In the 0 - 180° area, 20 mm pine wood targets 2, 3 mm Q235 steel targets 3, 5 mm Q235 steel targets 4 and 15 mm armor steel 5 are respectively arranged. At the same time, a metal mesh target 1 is arranged in the 0° - - 180° area as a control area. In the dynamic power test, the warhead is detonated at the explosion center position, and the comprehensive damage of each target plate by damage elements within the layout range is counted, and damage such as ignition and target penetration occurs to realize the evaluation of the damage power of the warhead. Specifically, it includes:

[0033] The metal mesh target 1 is arranged in the 0°-180° region: taking the explosion center as the origin, the heading direction is 0°, the counterclockwise is positive angle, and the clockwise is negative angle, the metal mesh target 1 is arranged in the 0°-180° region, the specification of the metal mesh target 1 is Φ0.7mm, the mesh number is 10, the aperture is Φ3.5mm, and the coverage area is 54400m 2 The metal mesh target 1 is arranged in the 0°-180° region: taking the explosion center as the origin, the heading direction is 0°, the counterclockwise is positive angle, and the clockwise is negative angle, the metal mesh target 1 is arranged in the 0°-180° region, the specification of the metal mesh target 1 is Φ0.7mm, the mesh number is 10, the aperture is Φ3.5mm, and the coverage area is 54400m

[0034] The rectangular region of the metal mesh target 1 is symmetric up and down along the extension line in the -90° direction of the origin; the rectangular region of the metal mesh target 1 is 20m longer than the region of each target or steel arranged in the 0°-180° region in the 0° direction and the 180° direction, so as to effectively increase the damage effect checking range.

[0035] The 20mm pine target 2, the 3mm Q235 steel target 3, the 5mm Q235 steel target 4 and the 15mm armor steel 5 are arranged in the 0°-180° region: specifically,

[0036] The 20mm pine target 2 is arranged: in the range of 80m to 160m from the explosion center, the radial interval is 10m, the 20mm pine target 2 is arranged starting from the 0° direction with a circumferential interval angle of 45°; the specification of the 20mm pine target 2 is 2m×1m, the thickness is 20mm, and a total of 80 pieces are arranged, which are used to represent the damage degree of the warhead to living personnel in the long-range range; specifically, the 20mm pine target 2 is usually equivalent to a personnel target in engineering, the target plate specification is 2m×1m, and in view of the principle of maximizing the damage effect of the warhead, since the personnel target has almost no survival ability in the medium and near field with high fragment density or shock wave overpressure value, combined with the static distribution law of the warhead explosion power test fragments, the fragment dispersion density of the warhead starts to decrease from 80m, so the 20mm pine target 2 is arranged from 80m from the explosion center, which can maximize the damage effect of the warhead to living personnel.

[0037] 3mm Q235 steel targets 3: Within a range of 0m to 100m from the blast center, 3mm Q235 steel targets 3 are laid out at radial intervals of 10m and circumferential intervals of 45° starting from the 0° direction. Target plates within a range of 0m to 40m are laid flat on the ground. The specifications of 3mm Q235 steel targets 3 are 2m × 1.5m, and 80 targets are laid out to serve as equivalent to aircraft targets on an apron.

[0038] 4 5mm Q235 steel targets were deployed: 5mm Q235 steel targets were deployed at a radial spacing of 5m and a circumferential spacing angle of 45° within a range of 40m to 100m from the blast center. The specifications of the 5mm Q235 steel targets were 2m×1.5m, and 80 targets were deployed. At the same time, a cotton blanket of the same size was deployed 300mm behind all the target plates to represent the damage of the warhead to enemy aircraft at medium and short range, such as the fuel tank of an aircraft-type target.

[0039] Specifically, the 3mm Q235 steel target 3 and 5mm Q235 steel target 4 are typically equivalent to vulnerable parts of targets such as aircraft on the tarmac in engineering. They are 2m × 1.5m in size. Since damage to targets such as aircraft depends on fragments with a certain penetration velocity and a certain fragment coverage area, and considering the attenuation law of fragment dispersion velocity in the static explosion test of the warhead, the fragment velocity of this type of warhead decreases to a lower value after 100m. Therefore, the 3mm Q235 steel target 3 is equivalent to the aircraft skin, which is deployed from 0m to 100m away from the blast center. The 5mm Q235 steel target 4 is often deployed with a cotton blanket of the same size 300mm behind it to be equivalent to the aircraft fuel tank. Considering the dispersion and ignition effect of active fragments, it is deployed from 40m to 100m away from the blast center.

[0040] 15mm armor steel 5 pieces were deployed: 15mm armor steel 5 pieces were deployed at radial intervals of 5m within a range of 40m to 80m from the blast center. The angle between the target plate and the ground at each position was adjusted according to the theoretical detonation point. The 15mm armor steel 5 pieces were 2m × 1.5m in size, with a total of 45 pieces deployed. These were used to represent light armored targets to characterize the damage degree of the warhead to armored vehicles at medium and long range. Specifically, the 15mm armor steel 5 pieces are usually equivalent to the vulnerable parts of most light armored targets in engineering. The size is 2m × 1.5m. Since the damage to light armored targets relies on fragments with high penetration velocity and a certain fragment density, combined with the fragment dispersion velocity decay law of the warhead static explosion test, the fragment velocity of the warhead begins to decrease from a high range after 40m. Taking into account the gradual decrease in fragment density after 80m, the deployment of 15mm armor steel 5 pieces within a range of 40m to 80m from the blast center can maximize the assessment of the damage degree of the warhead to armored vehicles.

[0041] Within the range of 0° to 180°, all equivalent target plate spacing and angles relative to the ground should be based on the fragment dispersion velocity V at that location. Rdirection and size, according to the static initial velocity V0 of the fragment determined by the static explosion test, V0 is a vector, the direction of which should satisfy the static explosion fragment dispersion density distribution function, V R The value is determined according to the following formula:

[0042] v R = v0exp(-KR)

[0043] K is the velocity attenuation coefficient, and R is the flight distance, in meters; wherein K is determined according to the following formula:

[0044] K = C x p a g / 2q 2 / 3

[0045] C x is the air resistance coefficient of the fragment, and for a spherical fragment, it is usually taken as 0.97; p1 is the shape coefficient of the fragment, and for a spherical fragment, it is usually taken as 1.2098 / p0 2 / 3 , p0 is the material density, p a is the local air density, and q is the mass of the fragment, and g is the value of the gravitational acceleration.

[0046] According to the calculated V R value, in combination with the falling speed of the projectile body, the size and direction of the dynamic speed of the fragment at different distances from the explosion center can be obtained.

[0047] According to the size and direction of the dynamic speed of the fragment, in order to ensure that the theoretical target direction of the fragment damage element is perpendicular to the target plate, the angle between each target plate and the ground is adjusted according to the distance from the explosion center: the 3mm Q235 steel target 3 should be laid flat on the ground within the range of 0-30m, the 20mm pine target 2, the remaining 3mm Q235 steel target 3, the 5mm Q235 steel target 4 and the 15mm armor steel 5 start from the radius of 40m, and the angle between the back of the target plate and the ground is 40° as the starting angle, and the angle should be increased by 3° every 5m, the angle should be decreased to 2° from the radius of 50m, and the angle should be decreased to 1° from the radius of 80m.

[0048] When the large-power multifunctional non-blind area killing explosive warhead reaches the explosion point at a certain falling speed, falling angle and explosion height, the fuze initiates the main charge, and the fragment damage element is loaded by the explosion in a range of 360° to enter the target distribution area, and all target plates are penetrated and damaged; the number of penetrated target plate bullet holes of the metal mesh target 1 is counted, which is used to check whether there is omission in the 0°-180° penetration. The number of penetrated target plates and the number of embedded target plates of the 20mm pine target 2 at different distances are counted, the effective fragment density is calculated, and the difference method is used for checking, so that the effective fragment density of 1.2 fragments / m 2The maximum distance and minimum distance from the explosion center of the technical index requirement in all directions are integrated, and the equivalent dense killing radius of the warhead on personnel is obtained. The number of target plate penetrations of 3mm Q235 steel target 3, 5mm Q235 steel target 4 and 15mm armor steel 5 at different distances and the burning condition of the cotton quilt laid behind the 5mm Q235 steel target 4 are counted, the effective fragment density is calculated, the maximum distance and minimum distance from the explosion center of the technical index requirement in all directions are obtained, and the effective killing area of the warhead on technical weapons is obtained by integrating the distance values in all directions, and it is judged whether the active fragments in the warhead can ignite the corresponding area of the cotton quilt equivalent effect. The whole damage process will be recorded by high-speed photographic instrument throughout the process, the explosion center is included in the camera range, and the explosion loading and fragment striking target plate process of the warhead are observed. According to the damage criterion of different targets, the comprehensive damage power of the warhead can be effectively analyzed by integrating all target damage conditions.

[0049] The present application can verify the dynamic damage power of large-scale killing and blasting warheads on various targets such as enemy aircraft fuel tanks, armored vehicles and living personnel by using a limited number of target plates. It is proved by experiments that the method can efficiently and low-costly obtain test related parameters, effectively analyze the damage power of the warhead such as fragment ignition ability, penetration rate and killing area, so as to improve the accuracy of warhead power verification.

[0052] In addition, various different embodiments of the present application can also be combined in any manner, as long as they do not deviate from the idea of the present application, and they should also be considered as disclosed by the present application.

The dynamic power test method of large power multi-functional non-blind area killing and blasting warhead according to claim 5, characterized in that, The warhead is detonated at the explosion center position, and the fragment damage element is loaded by explosion in a range of 360° to enter the target area, and all target plates are penetrated and damaged; The number of target plate bullet holes of the metal mesh target is counted to check whether there is any omission in the penetration of the target in the range of 0°-180°. The number of target plate penetration and the number of embedding of 20 mm pine targets at different distances are counted, the effective fragment density is calculated, and the difference method is used for checking, so as to obtain the maximum distance and minimum distance from the explosion center that can reach the technical index requirement of 1.2 pieces / m 2 in all layout directions, and the distance value of all directions, that is, the equivalent dense killing radius of the warhead to personnel can be obtained. The number of target plate penetrations of the 3 mm Q235 steel target, 5 mm Q235 steel target and 15 mm armor steel at different distances is counted, and the burning of the cotton quilt placed behind the 5 mm Q235 steel target is counted, the effective fragment density is calculated, the maximum distance and the minimum distance from the explosion center in all directions where there are target plate bullet holes are obtained, and the distance value in all directions is comprehensive, that is, the effective killing area of the technical weapon of the warhead can be obtained, and it can be judged whether the active fragment in the warhead can ignite the cotton quilt in the corresponding area. The whole damage process is recorded by high-speed photography instruments, the explosion center is included in the camera range, and the process of warhead explosion loading and fragment hitting the target plate is observed; according to the damage criterion of different targets, the comprehensive damage power of the warhead can be effectively analyzed according to the damage criterion of different targets.
