Problems solved by technology

However, its disadvantage is obvious. It can only explain the uniformity from the quantitative level. When the number of submunition scattered points in the area is relatively average, but the scattered points in the same area are seriously clustered, the uniformity obtained by this method is obviously not in line with the objective facts. of

Embodiment 1

[0026] The distribution of submunition scatter points is as follows: figure 1 shown. S1. Select a point in the dispersal area of ​​submunitions as point O, take the due east as the positive direction of the X axis, and take the due north as the positive direction of the Y axis, so as to establish the XOY plane coordinate system of the dispersing points of the submunitions. After specifying the unit length, determine There are a total of 100 coordinate points of all submunition scatter points, and the coordinates of submunition scatter points are shown in Table 1 at the end of the article.

[0027] Subsequently, use the straight line to connect the scatter points of the sub-munitions on the edge of the scattered area successively to determine the closed convex polygon formed by the unique scatter point coordinates of the sub-clusters. The closed convex polygon area of ​​the present embodiment consists of the 6th, 11, 13, 17, 26, 30 , No. 38, No. 42, and No. 56 submunition dist...

Embodiment 2

[0033] The distribution of submunition scatter points is as follows: figure 2 shown. S1. Select a point in the dispersal area of ​​submunitions as point O, take the due east as the positive direction of the X axis, and take the due north as the positive direction of the Y axis, so as to establish the XOY plane coordinate system of the dispersing points of the submunitions. After specifying the unit length, determine There are a total of 120 coordinate points of all submunition scatter points, and the coordinates of submunition scatter points are shown in Table 3 at the end of the article.

[0034] Subsequently, use the straight line to connect the scatter points of the sub-munitions on the edge of the scattered area successively to determine the closed convex polygon formed by the unique scatter point coordinates of the sub-munitions. The closed convex polygon area of ​​the present embodiment consists of the 1st, 16, 22, 26, 31, 32 , 35, 39, 50, 56, 74, 87, 100, 101, and 105...

Abstract

The invention discloses a child-mother bomb uniformity evaluation method fusing an exclusive circle theory. The method comprises the following steps of: determining a closed polygonal region formed bythe child-mother bomb scattering points, determining the radius Li and the area Si of the exclusive circle of the ith child-mother bomb scattering point until the radiuses and the areas of the exclusive circles of all the child-mother bomb scattering points are determined, determining the area sum S of all the exclusive circles, and obtaining the child-mother bomb scattering uniformity K throughcalculation. Rapid and accurate quantitative evaluation calculation can be carried out on the distribution uniformity characteristics of the child-mother bombs, the situation that only qualitative judgment can be carried out in the past is changed, and meanwhile, the method has universal adaptability to evaluation of the distribution uniformity of various cluster child-mother bombs carried by multiple platforms such as air-surface missiles and ground missiles.

Description

technical field [0001] The invention belongs to the technical field of submunitions, and in particular relates to a method for evaluating the uniformity of submunitions combined with the exclusive circle theory. Background technique [0002] Submunitions are shells that use the parent projectile as a carrier and contain a certain number of bullets. After firing, the parent projectile opens the cabin at a predetermined height and ejects bullets to complete damage to targets and other special combat tasks. It is used to damage cluster tanks, armored vehicles, technical equipment, kill vital forces or lay mines. It is equipped with medium and large caliber artillery, mortar, etc., including aerial bombs and missiles. [0003] The submunitions usually enter the near field of the target 100 meters above the sky, and complete the group submunition ejection cabin through capsule or tube throwing. The submunitions are adjusted and decelerated through the deceleration parachute, and...
