Description

Technical Field

[0001] This invention relates to the field of weapon ammunition initial velocity and burst velocity measurement technology, and in particular to a ballistic indication device for rapid target deployment. Background Technology

[0002] In the design and production of weapons and ammunition, projectile muzzle velocity is a crucial technical indicator for evaluating weapon performance, and muzzle velocity and burst velocity measurement equipment are essential equipment for weapon and ammunition design and production departments. Currently, in actual range testing, the commonly used muzzle velocity and burst velocity measurement equipment are sky-screen targets and light-screen targets based on the intercept measurement principle. The intercept measurement principle is as follows: given the target distance, measure the projectile's transit time and calculate the average velocity at the midpoint of the target distance.

[0003] The aerial target system employs a mobile field deployment mode, using two or four aerial targets to measure the initial velocity of the projectile. In actual range applications, the spatial position of the aerial targets is manually adjusted, leading to inconsistencies in the spatial positions of the targets used. Using a measuring tape to measure the distance between two aerial targets presents a problem of uncontrollable error in the target distance length. A prerequisite for accurate target distance measurement is that the detection light curtain must be aligned perpendicular to the ballistic trajectory during measurement.

[0004] Therefore, for those skilled in the art, how to achieve vertical alignment between the detection light curtain and the ballistic line during measurement, so as to accurately measure the target distance and thus the projectile's initial velocity, has become an important problem that urgently needs to be solved. Summary of the Invention

The optical instruments are arranged in a straight line and located directly below the ballistic indicator device. The two fixed-target lasers are located on both sides of the optical axis laser and are symmetrically placed relative to the optical axis laser. The 3-axis adjustment platform is adjusted so that the collimated laser beam emitted by the fixed-target laser illuminates the center line of the sky curtain target.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the ballistic indication device provided by this invention for rapid target deployment measures the projectile velocity by generating two fan-shaped probe light curtains through an initial and an ending celestial target.

[0021] To make the objectives, content, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings and examples. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] To address the problems of existing technologies, the design concept of this invention is to provide a positional reference for the vertical alignment of the light curtain plane with the ballistic line for a target range, whether it be a canopy target or a reflective target. The ballistic indicator device is fixed directly above the canopy target using a bracket. The optical axis laser of the ballistic indicator device indicates the optical axis position of the detection light curtain. A 3-axis adjustment platform is used to adjust the attitude of the ballistic indicator device, aligning the optical axis indicator with the midpoint of the center line of the canopy target. Below the ballistic indicator device are two fixed-target lasers. The horizontal angle of the ballistic indicator is adjusted using a 3-axis adjustment platform, aligning the collimated laser beam with the center line of the canopy target. The support and adjustment mechanisms of the canopy target are adjusted to ensure that the beam landing point of the fixed-target lasers is symmetrical about the midpoint of the center line. After adjustment, the ballistic indicator device is positioned vertically above and parallel to the canopy target. The ballistic indicator device is spatially perpendicular to the fixed-target lasers through mechanical structure design. Activating the ballistic indicator device aligns the ballistic indicator laser with the center position of the muzzle. The direction of the ballistic indicator laser represents the ballistic line, thus ensuring that the detection light curtain of the canopy target is perpendicular to the ballistic line.

[0023] Specifically, the technical solution of the present invention is as follows:

[0024] A ballistic indication device for rapid target deployment, the target comprising: an initial celestial canopy target and an terminating celestial canopy target, each capable of generating a fan-shaped detection light curtain, the initial celestial canopy target and the terminating celestial canopy target being placed at a certain distance apart in front of the artillery muzzle along the projectile's firing direction.

The devices are arranged in a straight line and located directly below the ballistic indicator. The two fixed-target lasers are located on both sides of the optical axis laser and are symmetrically placed relative to the optical axis laser. The 3-axis adjustment platform is adjusted so that the collimated laser beam emitted by the fixed-target laser illuminates the center line of the sky curtain target. The ballistic indicator is designed to be perpendicular to the fixed-target laser in space through a mechanical structure. The laser beam emitted by the ballistic indicator is a ballistic line perpendicular to the optical axis of the detection light curtain. The upper end of the bracket fixes the ballistic indicator device, and the lower end is provided with screw holes for use and fixation with the sky curtain target support and adjustment mechanism.

[0026] As an improvement to the above solution, the sky-canopy target also includes an optical system and a support and adjustment mechanism.

[0029] As an improvement to the above solution, the ballistic indication device can also be used for reflective light curtain targets. Example

[0030] refer to Figure 1 This is an overall schematic diagram of a ballistic indication device for rapid target deployment according to Embodiment 1 of the present invention. The ballistic indication device for a canopy target in this embodiment of the present invention includes a starting canopy target 1, a ending canopy target 2, and ballistic indication devices 3 and 4. The initial and final target arrays 1 and 2 are placed at a certain distance in front of the artillery muzzle along the projectile's firing direction to generate a fan-shaped detection light curtain to measure the projectile's velocity. Ballistics indicating devices 3 and 4 are fixed above the initial and final targets using supports. The ballistics indicating device 3 activates its optical axis laser, and its position is adjusted using a 3-axis adjustment table to align the laser beam with the midpoint of the target array's centerline. The target laser is also activated, and its horizontal position is adjusted using the 3-axis adjustment table to align the collimated laser beam with the target array's centerline. The two target lasers are symmetrical about the optical axis indicator. The support and adjustment mechanisms of the target array are adjusted so that the laser beam's landing point is symmetrical about the midpoint of the centerline. The adjusted ballistics indicating device is positioned vertically above and parallel to the target array. According to geometric theorems, in the parallel projection of an object, the projection lines are perpendicular to the projection plane; this parallel projection is called orthographic projection. Three parallel lines in the same plane can define a plane. The optical axis indicating laser and the collimated lasers emitted by the two target lasers form the projection lines of the celestial target and the ballistic designator, ensuring that the celestial target and the ballistic designator are orthographically projected in space. These three parallel projection lines define a reference plane. This visible reference plane formed by these three projection lines is the objective of this embodiment. The ballistic designator is spatially perpendicular to the two target lasers via a mechanical mechanism. The 3-axis adjustment platform is used to align the indicating laser emitted by the ballistic designator with the center of the gun muzzle, and the distance to the gun muzzle is measured using the laser rangefinder of the ballistic designator.

[0031] Among them, reference Figure 1 and Figure 2 The initial canopy target 1 also includes an optical system 11, a center point 12, a center line 13, and a support and adjustment mechanism 14. The optical system 11 can generate a fan-shaped detection light curtain 101 to measure the projectile velocity. The center point is the starting point of the optical axis of the canopy target forming the detection light curtain, and the center line 13 is the center position of the canopy target. The support and adjustment mechanism 14 can stably support the initial canopy target 1 in the field environment and allow the detection light curtain to be translated or rotated, and can fix the support of the ballistic indicator device.

[0032] refer to Figure 3 and Figure 4 The ballistic indication device 3 also includes a ballistic indication body 31 and a support part 32. The ballistic indication body 31 includes a 3-axis adjustment platform, a ballistic indication laser 301, an optical axis indicator 302, and a target laser 303. The laser beams emitted by the optical axis indicator 302 and the target laser 303 serve as projection lines on the spatial positions of the ballistic indication device 3 and the sky target 1. In use, the 3-axis adjustment platform is adjusted so that the optical axis indicator 302 on the ballistic indication device 3 is aligned with the midpoint 12 of the center line of the initial sky target 1. Then, the target laser 303 of the ballistic indication device is turned on, and the 3-axis adjustment platform is adjusted so that the ballistic indication device 3 is aligned with the center line of the sky target 1. The support and adjustment mechanism 14 of the sky target is adjusted so that the beam landing point of the target laser is symmetrical about the midpoint 12 of the center line. After adjustment, the ballistic indication device is located directly above the sky target and parallel to the sky target, realizing that the ballistic indication device 3 and the sky target 1 are mutually orthogonal projections in spatial position. The ballistic indicator of the ballistic designator utilizes a mechanical structure to ensure spatial perpendicularity with the target laser. A 3-axis adjustment table is used to adjust the ballistic indicator device 3 so that the ballistic indicator laser is aligned with the center of the gun muzzle, and the muzzle distance is measured. Similarly, the ballistic indicator device 3 on the initial canopy target 1 is reversed and fixedly connected to the support and adjustment mechanism 24 of the terminating canopy target 2 via a bracket. Following these operations, the detection light curtain planes of the initial and terminating canopy targets are made perpendicular to the ballistic line, and the two detection light curtains are parallel to each other. The muzzle distance and target distance can be measured using ballistic indicator devices 3 and 4. Removing ballistic indicator devices 3 and 4 completes the adjustment and vertical alignment work.

[0033] The above example illustrates the design principle and on-site operation process of this embodiment. This embodiment is used in conjunction with a sky-canopy target to provide a spatial position reference mark for the intercept-type velocity measuring device.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
