Since the image characteristics of such threat targets are difficult to simulate in the existing test environment, there is a lack of sufficient theoretical and data support for the evaluation of the damage effectiveness against such targets. Most of them use static penetration test results to infer dynamic test results, that is, by penetrating static targets, and then using theoretical formulas to infer dynamic penetration test results, or by penetrating and destroying low-speed target aircraft to evaluate the terminal damage effect of artillery ammunition, which has a certain gap with actual combat against high-speed moving targets such as precision-guided weapons, lacks confidence, and is difficult to evaluate in terms of accuracy.

Three groups of tests were performed.

[0051] 1. The first group of experiments

[0052] Test purpose: To examine and record the damage effect of shooting at a moving target with a linear velocity of 0 m / s.

[0053] Number of shots: 3 shells x 1 shot.

[0054] Shooting mode: single shot.

[0055] Data processing: measure the size of the hole made by the shell penetrating the target plate and take photos to record the test images.

[0056] Qualification criteria: The ability to fire normally is qualified.

[0057] 2. The Second Group of Experiments

[0058] Test purpose: To examine and record the damage effect of shooting at a moving target with a linear speed of 120m / s.

[0059] Number of shots: 3 shells x 1 shot.

[0060] Shooting mode: single shot.

[0061] Data processing: measure the size of the hole made by the shell penetrating the target plate and take photos to record the test images.

[0062] Qualification criteria: The ability to fire normally is qualified.

[0063] 3. The second group of experiments

[0064] Test purpose: To examine and record the damage effect of shooting at a moving target with a linear speed of 300m / s.

[0065] Number of shots: 3 shells x 1 shot.

[0066] Shooting mode: single shot.

[0067] Data processing: measure the size of the hole made by the shell penetrating the target plate and take photos to record the test images.

[0068] Qualification criteria: The ability to fire normally is qualified.

[0069] The data obtained from the three groups of tests were then tabulated, with the comparison of the dynamic penetration test results and the static penetration test results shown in Table 1.

[0070] Table 1 Comparison of shooting test results

[0071]

[0072] As can be seen from Table 1, the first test including Test 1, Test 2 and Test 3 is a static penetration, that is, the rotating target 300 is three penetrations in a stationary state;

[0073] The second test includes test 4, test 5 and test 6 for dynamic penetration, that is, three dynamic penetrations with the rotating target 300 rotating at a speed of 120 m / s;

[0074] The third test includes Test 7, Test 8 and Test 9, which are three dynamic penetrations of the rotating target 300 at a speed of 300 m / s;

[0075] In summary, by taking the average value of the three groups of test data, the average damage hole sizes of the target plate 320 at rotation speeds of 0, 120m / s, and 300m / s are 22.8mm×21.3mm×25mm, 26.9mm×24.8mm×25mm, and 48.1mm×25.7mm×25mm, respectively. The test results show that as long as the shell hits and penetrates the target plate, as the speed of the target plate 320 increases, the hole formed by the projectile on the target plate 300 becomes larger, and the aspect ratio of the hole morphology on the test image increases with the increase of the target plate speed.
