Embodiment 1

[0030] The present invention is a wedge-shaped light curtain array measuring the initial velocity of the array barrel apparatus. The object array of the object used is a firing device with a barrel of 2×2, and the position of the barrel is schematically illustrated Figure 1 as shown. asFigure 3 As shown, the measuring device is composed of a wedge light curtain array, a signal processing and amplification module 3 and a connecting rod 4, the wedge light curtain array is specifically a wedge four light curtain array, wherein each wedge light curtain is composed of a light source 1 and a photodiode receiving module 2, may also share a light source 1, photodiode module 2 perpendicular to the middle line of the light source 1, such as Figure 2 as shown. Light source 1 is installed on the light source structure frame 5, photodiode module 2 and signal processing module 3 is installed in the receiving device structure box 6, the light source structure box 5 and the receiving device struc...

Embodiment 2

[0032] Measuring apparatus as in Example 1, supposes as Figure 4 The angle between the wedge-shaped light curtains shown β 1 ＝β 2 ＝β 3 ＝β 4 = β, the spatial position of the barrel of the array barrel corresponds to each light curtain in the wedge-shaped four-light curtain array, the corresponding position of the A barrel and the angle between the light source and the light source are γ, and the vertical distance from the light source 1 is H, the distance from the Y axis where the light source 1 is located is x, and the distance between the light source 1 and the photoelectric receiving device is R, such as Figure 4 as shown. Then there are:

[0033]

[0034] As can be seen from the diagram, <γ<β 0, the maximum critical value of the γ is β, then:

[0035]

[0036] When L is the fixed value, x has a maximum value namely

[0037]

[0038] That is, the smaller the R, the greater the γ; the larger the R, the smaller the γ; and when R is a fixed value, the | The smaller the EF |,...

Embodiment 3

[0042] Measuring apparatus such as Example 1, the light source structure box 5 and the receiving device structure box 6 are equipped with a cylindrical laser standard indicator 7 on both sides, when the measuring device is installed, according to the corresponding laser standard indicator beam coincidence to ensure the accuracy of the installation.

[0043] The two edges of the field of view of each wedge light curtain can be equipped with a columnar laser as a demarcation from the other light curtain, aligned with the barrel when used, in order to distinguish which area it is in.

Abstract

The invention discloses a device and method for measuring the muzzle velocity of an array gun barrel by a wedge-shaped light curtain array. The device is composed of a wedge-shaped light curtain array, a signal processing and amplification module and a connecting rod. The wedge-shaped light curtain array is composed of two or more wedge-shaped light curtains, and the wedge-shaped light curtain is composed of a light source and a photodiode receiving module. The two sets of the same measuring devices are arranged at a certain distance, equipped with corresponding testers or signal acquisition devices. When the projectile passes through the two sets of measuring devices successively, each wedge-shaped light curtain outputs the signal of the projectile passing through the screen, and the speed is measured according to the area. The principle and the spatial position relationship of the wedge-shaped light curtain array can realize the measurement of the muzzle velocity of the array gun barrel. The invention has the advantages of simple structure and convenient target arrangement, and is suitable for testing the initial velocity of projectiles fired by array gun barrel salvos.

Description

Technical field [0001] The present invention belongs to the field of range testing technology, mainly relates to the use of light curtain array technology to achieve the measurement of the initial velocity of multiple projectiles firing at the same time, in particular to a two or four gun array barrel salvo firing continuous projectile velocity measurement and sequence identification device and method, specifically a wedge-shaped light curtain array measurement array barrel projectile initial velocity device and method. Background [0002] Multiple rotary tube guns or array gun barrel weapons, high rate of fire, multiple projectiles fired continuously can form a barrage in space, can effectively destroy incoming missiles or unmanned aerial vehicle groups, and are the key equipment of the ship's low-altitude defense system. The dynamic barrage parameters of its launch, especially the flight parameters of the projectile (including speed, target position, attitude, etc.), are the ke...
