Description

Technical Field

[0001] This application relates to a test method for the detonation point of an empty bomb, specifically a test method for testing the detonation point of an empty bomb in a dual-station configuration. Background Technology

[0002] The current development of new air-bomb fragmentation munitions requires measuring the point of detonation of the projectile in mid-air to assess the destructive effects after the explosion. Therefore, it is necessary to test the distance to the point of detonation of the air-bomb. The traditional method involves placing a single high-speed camera directly opposite the point of detonation along the ballistic trajectory to photograph the air-bomb projectile, and then processing the data to obtain the distance to the point of detonation. While this method can measure the distance to the point of detonation, it is difficult to obtain the directional offset of the point of detonation, and there is a reading error due to the air-bomb deviating left or right along the ballistic trajectory near the point of detonation before exploding, which affects the accuracy of the air-bomb distance data. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a test method for testing the detonation point of an empty bomb in a dual-station manner, including:

[0010] The distance L from the blast point is calculated according to formula (1), which is: L = (L1·L22-L2·L11) / [(L1-L11)+(L22-L2)];

[0011] The offset S of the explosion point is calculated according to formula (2), which is: S=±C(L1-L2) / [(L1-L11)-(L2-L22)].

[0016] Read the pixel value D1 of the projection point of the actual explosion point in the first image onto the projection line;

[0017] The value of L1 is calculated using M1, N1, R, A1, and D1.

[0018] According to the technical solution provided in the embodiments of this application, the values ​​of M1, N1, R, A1 and D1 are substituted into L1=|(D1-A1)•(N1-M1) / R| to calculate the value of L1.

[0019] According to the technical solution provided in the embodiments of this application, the method for calculating L2 includes:

[0020] The pixel value M2 at one end of the second scale and the pixel value N2 at the other end are read from the second image respectively.

[0022] Read the pixel value E1 of the projection point of the actual explosion point in the second image onto the projection line;

[0023] The value of L2 is calculated using M2, N2, R, A2, and E1.

[0024] According to the technical solution provided in the embodiments of this application, the values ​​of L2 are calculated by substituting M2, N2, R, A2 and E1 into L2=|(E1-A2)•(N2-M2) / R|.

[0025] According to the technical solution provided in the embodiments of this application, the test method for testing the detonation point of a dual-station empty bomb further includes:

[0026] Determine whether L1 and L2 are equal;

[0027] If they are equal, then the actual explosion point has not shifted;

[0028] If they are not equal, the actual detonation point offset is calculated using the formula (1) and the formula (2) to determine the detonation point distance L and the detonation point offset S.

[0029] According to the technical solution provided in the embodiments of this application, the test method for testing the detonation point of a dual-station bomb further includes: connecting the first test point P1 and the second test point P2 to obtain a third straight line; when the projection point is located between the first projection line and the third straight line, the detonation point offset S takes a positive value; when the projection point O is located on the side of the first projection line away from the third straight line, the detonation point offset S takes a negative value.

[0030] According to the technical solution provided in the embodiments of this application, the formulas (1) and (2) are derived using trigonometric functions. The derivation process includes:

[0031] Project the actual explosion point onto the first plane to obtain the projection point O of the actual explosion point; draw a perpendicular line from the projection point O to the first projection line, and mark the foot of the perpendicular as point O1. The length of line segment AO1 is the explosion point distance L, and the length of line segment OO1 is the explosion point offset S.

[0032] Draw a first straight line through the first test point P1 and point O. The intersection of the first straight line and the first projection line is marked as B1, and the length of line segment AB1 is denoted as L1.

[0033] Determine the first angle α formed by the first straight line and the first projection line. The first angle α is an acute angle. According to the tangent theorem, tanα = C / (L1-L11) = S / (L1-L).

[0035] Determine the second included angle β formed by the second straight line and the first projection line. The second included angle β is an acute angle. According to the tangent theorem, tanβ = C / (L2² - L2) = S / (L - L2).

[0036] Formula (1) and formula (2) are derived from tanα=C / (L1-L11)=S / (L1-L) and tanβ=C / (L22-L2)=S / (L-L2).

[0037] Beneficial effects: By arranging a first high-speed camera and a second high-speed camera at the first test point P1 and the second test point P2 on one side of the first projection line, respectively, the dual-station high-speed cameras capture the actual trajectory of the projectile and the actual detonation point. Based on the data analysis of the first image captured by the first high-speed camera, the value of L1 is obtained. Based on the data processing of the second image captured by the second high-speed camera, the value of L2 is obtained. Then, the values ​​of C, L11, and L22 are measured using a measuring ruler. Then, they are substituted into formula (1): L=(L1·L22-L2·L11) / [(L1-L11)+(L22-L2)] and formula (2): S= ±C(L1-L2) / [(L1-L11)-(L2-L22)] to obtain the detonation point distance L and the detonation point offset S. This dual-station test method for testing the detonation point of an empty bomb is simple to operate. The measured data can be substituted into the formula to obtain the detonation point distance and the detonation point direction offset, and the test results are more accurate.

[0044] Please refer to Figures 1-2 A test method for testing the detonation point of an empty bomb in a dual-station configuration includes:

[0045] With the gun position fixed, the ideal ballistic line and ideal impact point are predicted based on the gun position. The ideal ballistic line is projected onto the first plane to obtain the first projection line. Point A is selected on the first projection line.

[0046] Select a first test point P1 and a second test point P2 on the first plane. The distances from both to the first projection line are equal, and the distance is denoted as C. Place a first high-speed camera and a second high-speed camera on the first test point P1 and the second test point P2 respectively, and adjust the shooting field of view of both cameras so that the shooting field of view of both cameras encompasses the ideal explosion point and the point A.

[0047] The projectile is launched, and the high-speed camera captures and records the trajectory and actual impact point of the projectile. The first high-speed camera captures a first image, and the second high-speed camera captures a second image.

[0048] Draw a perpendicular line from point P1 to the first projection line, with the foot of the perpendicular marked as C1, and the length of line segment AC1 denoted as L11. Draw a perpendicular line from point P2 to the first projection line, with the foot of the perpendicular marked as C2, and the length of line segment AC2 denoted as L22.

[0049] Obtain the distance L1 from the midpoint A of the first image to the projection point of the actual explosion point on the projection line;

[0050] Obtain the distance L2 from the midpoint A of the second image to the projection point of the actual explosion point on the projection line;

[0051] The distance L from the blast point is calculated according to formula (1), which is: L = (L1·L22-L2·L11) / [(L1-L11)+(L22-L2)];

[0052] The offset S of the explosion point is calculated according to formula (2), which is: S = ±C(L1-L2) / [(L1-L11)-(L2-L22)].

[0053] In this embodiment, the projectile launching device is fixed on the ground, and the angle of the barrel is adjusted in preparation for launching the projectile.

[0054] In this embodiment, the ideal ballistic trajectory is predicted based on the direction of the gun barrel.

[0055] In this embodiment, the ideal detonation point is predicted based on the type of the launching device.

[0056] In this embodiment, the ground plane is used as the first plane; the first projection line is marked on the ground plane, and point A is selected on the first projection line, and a marker is erected at point A.

[0057] In this embodiment, when selecting the first test point P1 and the second test point P2, the first test point P1 and the second test point P2 are located on the same side of the first projection line and near the actual explosion point.

[0058] In this embodiment, when adjusting the shooting field of view of the high-speed camera, it is necessary to ensure that the shooting field of view of the high-speed camera includes the benchmark and the ideal explosion point at point A, and leave a margin to ensure that the high-speed camera can capture the actual explosion point.

[0059] In this embodiment, C, L11, and L22 are obtained by measuring with a measuring ruler.

[0060] Working principle: A first high-speed camera and a second high-speed camera are respectively arranged at the first test point P1 and the second test point P2 on one side of the first projection line. The dual-position high-speed camera captures the actual trajectory of the projectile and the actual detonation point. Data analysis is performed on the first image captured by the first high-speed camera to obtain the value of L1. Data processing is performed on the second image captured by the second high-speed camera to obtain the value of L2. Then, the values ​​of C, L11, and L22 are measured using a measuring ruler. Then, they are substituted into formula (1): L=(L1·L22-L2·L11) / [(L1-L11)+(L22-L2)] and formula (2): S=±C(L1-L2) / [(L1-L11)-(L2-L22)] to obtain the detonation point distance L and the detonation point offset S. This test method is simple to operate. The measured data can be substituted into the formula to obtain the detonation point distance and the detonation point direction offset. Moreover, the test results are more accurate.

[0061] In a preferred embodiment, the test method for testing the detonation point of an empty bomb in dual-station mode further includes: placing a first scale within the field of view of the first high-speed camera and a second scale within the field of view of the second high-speed camera before launching the projectile, wherein the length of both the first scale and the second scale is R.

[0062] Specifically, when placing the first ruler, it is necessary to ensure that the first test point P1 is located on the vertical line of the first ruler.

[0063] Specifically, when placing the second ruler, it is necessary to ensure that the second test point P2 is located on the vertical line of the second ruler.

[0064] Specifically, markers are erected at both ends of the first ruler and the second ruler, respectively, so that the first high-speed camera can capture the two ends of the first ruler and the second high-speed camera can capture the two ends of the second ruler.

[0065] In a preferred embodiment, the method for calculating L1 includes:

[0066] The pixel value M1 at one end of the first scale and the pixel value N1 at the other end are read from the first image respectively.

[0067] Read the pixel value A1 of point A on the first image;

[0068] Read the pixel value D1 of the projection point of the actual explosion point in the first image onto the projection line;

[0069] The value of L1 is calculated using M1, N1, R, A1, and D1.

[0070] It is worth noting that:

[0071] In actual testing, such as Figure 1 and Figure 2 As shown, L1 is the length of line segment AB1. However, when analyzing and processing the first image, since the first image is a planar image, the distance from the projection point of the first projection line to point A of the actual explosion point on the first image is the value of L1.

[0072] In a preferred embodiment, the values ​​of L1 are calculated by substituting M1, N1, R, A1 and D1 into L1 = |(D1-A1)•(N1-M1) / R|.

[0073] In a preferred embodiment, the method for calculating L2 includes:

[0074] The pixel value M2 at one end of the second scale and the pixel value N2 at the other end are read from the second image respectively.

[0075] Read the pixel value A2 of point A on the second image;

[0076] Project the actual explosion point on the second image onto the first projection, and read the pixel value E1 of the actual explosion point in the second image at the projection point of the projection line;

[0077] The value of L2 is calculated using M2, N2, R, A2, and E1.

[0078] Specifically, the method of processing the value of L2 using the second image is the same as the method of processing the value of L1 using the first image, and will not be described in detail here.

[0079] In a preferred embodiment, the values ​​of L2 are calculated by substituting M2, N2, R, A2 and E1 into L2 = |(E1-A2)•(N2-M2) / R|.

[0080] In a preferred embodiment, the test method for testing the detonation point of an empty bomb in a dual-station configuration further includes:

[0081] Determine whether L1 and L2 are equal;

[0082] If they are equal, then the actual explosion point has not shifted;

[0083] If they are not equal, the actual detonation point offset is calculated using the formula (1) and the formula (2) to determine the detonation point distance L and the detonation point offset S.

[0084] In a preferred embodiment, the test method for testing the detonation point of a dual-station airbomb further includes: connecting the first test point P1 and the second test point P2 to obtain a third straight line; when the projection point O is located between the first projection line and the third straight line, as... Figure 1 As shown, the explosion point offset S is a positive value; when the projection point O is located on the side of the first projection line away from the third straight line, as... Figure 2 As shown, the explosion point offset S takes a negative value.

[0085] In a preferred embodiment, formulas (1) and (2) are derived using trigonometric functions. The derivation process includes:

[0086] Project the actual explosion point onto the first plane to obtain the projection point O of the actual explosion point; draw a perpendicular line from the projection point O to the first projection line, and mark the foot of the perpendicular as point O1. The length of line segment AO1 is the explosion point distance L, and the length of line segment OO1 is the explosion point offset S.

[0087] Draw a first straight line through the first test point P1 and point O. The intersection of the first straight line and the first projection line is marked as B1, and the length of line segment AB1 is denoted as L1.

[0088] Determine the first angle α formed by the first straight line and the first projection line. The first angle α is an acute angle. According to the tangent theorem, tanα = C / (L1-L11) = S / (L1-L).

[0089] Draw a second straight line through the second test point P2 and point O. The intersection of the second straight line and the first projection line is marked as B2, and the length of line segment AB2 is denoted as L2.

[0090] Determine the second included angle β formed by the second straight line and the first projection line. The second included angle β is an acute angle. According to the tangent theorem, tanβ = C / (L2² - L2) = S / (L - L2).

[0091] Formula (1) and formula (2) are derived from tanα=C / (L1-L11)=S / (L1-L) and tanβ=C / (L22-L2)=S / (L-L2).

[0092] Specifically, both RT∆P1B1C1 and RT∆OB1O1 have a first included angle α. In RT∆P1B1C1, tanα=C / B1C1, and in RT∆OB1O1, tanα=S / B1O1. Therefore, tanα=C / B1C1=S / B1O1.

[0093] Furthermore, since B1C1=L1-L11 and B1O1=L1-L, tanα=C / (L1-L11)=S / (L1-L).

[0094] Specifically, both RT∆P2B2C2 and RT∆OB2O1 have a second included angle β. In RT∆OB2B1, tanβ=C / B2C2, and in RT∆OB2O1, tanβ=S / B2O1. Therefore, tanβ=C / B2C2=S / B2O1.

[0095] Furthermore, since B2C2=L22-L2 and B2O1=L-L2, tanβ=C / (L22-L2)=S / (L-L2).

[0096] Furthermore, in the equations C / (L1-L11)=S / (L1-L) and C / (L22-L2)=S / (L-L2), C, L1, L11, L2, and L22 are known numbers, while S and L are unknowns. By solving the system of quadratic equations, we finally obtain formula (1): L=(L1·L22-L2·L11) / [(L1-L11)+(L22-L2)] and formula (2): S= ±C(L1-L2) / [(L1-L11)-(L2-L22)].

[0097] Experimental procedure:

[0098] S1: Fix the gun position of the projectile launching device, adjust the firing angle of the gun barrel of the projectile launching device, predict the ideal ballistic line and the ideal explosion point according to the gun position and the direction of the gun barrel, project the ideal ballistic line onto the first plane to obtain the first projection line, select point A on the first projection line, and erect a marker at point A.

[0099] S2: Select the first test point P1 and the second test point P2, measure and record the lengths of C, L11 and L22. Place the first high-speed camera and the second high-speed camera at the first test point P1 and the second test point P2 respectively. Place the first ruler in front of the first high-speed camera and the second ruler in front of the second high-speed camera. Adjust the field of view of the first camera so that it encompasses the ideal explosion point, the pole erected at point A, and the poles erected at both ends of the first ruler, with a margin. Adjust the field of view of the second camera so that it encompasses the ideal explosion point, the pole erected at point A, and the poles erected at both ends of the first ruler, with a margin.

[0100] S3: Launch the projectile. The first high-speed camera and the second high-speed camera capture and record the trajectory of the projectile and the actual impact point, obtaining the first image and the second image.

[0101] S4: Process the first image, read the pixel value A1 of point A, the pixel value M1 of one end of the first ruler, the pixel value N1 of the other end of the first ruler, and the pixel value D1 of the projection point obtained by projecting the actual explosion point onto the first projection line. Substitute these values ​​into L1=|(D1-A1)•(N1-M1) / R| to calculate the value of L1.

[0102] S5: Process the second image, read the pixel value A2 of point A, the pixel value M2 of one end of the second ruler, the pixel value N2 of the other end of the second ruler, and the pixel value E1 of the projection point obtained by projecting the actual explosion point onto the first projection line. Substitute these values ​​into L2=|(E1-A2)•(N2-M2) / R| to calculate the value of L2.

[0103] S6: Determine if L1 and L2 are equal;

[0104] S7: If L1 and L2 are not equal, substitute the values ​​of L1, L2, C, L11 and L22 into formula (1): L=(L1·L22-L2·L11) / [(L1-L11)+(L22-L2)], formula (2): S=±C(L1-L2) / [(L1-L11)-(L2-L22)] to calculate the distance L of the explosion point and the offset S of the explosion point.

[0105] S8: Connect the first test point P1 and the second test point P2 to obtain the third straight line. When the projection point O is located between the first projection line and the third straight line, as shown... Figure 1As shown, the explosion point offset S is a positive value; when the projection point O is located on the side of the first projection line away from the third straight line, as... Figure 2 As shown, the explosion point offset S takes a negative value.

[0106] This experimental method is simple to operate. You only need to substitute the measured data into the edited formula to obtain the distance to the explosion point and the offset of the explosion point direction, and the test results are more accurate.
