Embodiment Construction

[0017] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] refer to figure 1 and figure 2 , a high-performance missile-borne laser, including an outer shell 1, the material of the above-mentioned outer shell 1 is polyimide, so that the outer shell 1 has surface gloss, high hardness and good weather resistance; the outer diameter of the middle part of the above-mentioned outer shell 1 Smaller than the outer diameter of the upper and lower parts, it greatly reduces the heat conduction area in contact with the projectile body and reduces heat diffusion. The edge of the top end of the outer shell 1 is conical, matching the inside of the fuse head 9, and the fuse head 9 is provided with a fastening washer 91 below the missile-borne laser.

[0019] refer to Figure 1 to Figure 3 , the housing 1 is provided with an accommodating chamber 10 with upper and lower openings, and the accommodating chamber 10 is seq...

Abstract

The invention relates to a high-performance missile-borne laser device. The high-performance missile-borne laser device comprises a shell, a containing cavity with an upper opening and a lower openingis formed in the shell, and an optical collimation lens, a laser device collimation assembly, a laser constant-power driving circuit board, a first elastic pressing ring, a columnar battery and a second elastic pressing ring are sequentially arranged in the containing cavity from top to bottom. The bottom end of the shell is detachably provided with a bottom cover, and a screw hole aligned with the negative electrode of the columnar battery is formed in the middle of the bottom cover. The containing cavity is filled with a filling and sealing material. The missile-borne laser device is machined into an H shape through the shell, so that the contact heat conduction area of the laser device and a projectile body is greatly reduced, thermal diffusion is reduced, and the laser device collimation assembly is protected against thermal shock of an external high-temperature environment. The optical collimation lens, the laser collimation assembly, the laser constant-power driving circuit board and the columnar battery are subjected to integrated solid-state filling and sealing, the crimp-type electrode structure guarantees the overall firmness and reliability of the whole laser device, and the laser device is reasonable in structural design, stable in performance and resistant to vibration.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a high-performance missile-borne laser. Background technique [0002] As a collimated emission light source, the missile-borne laser is used for the measurement of projectile motion attitude (rotation shaking) parameters in the semi-confinement period. It is a key component of the projectile motion attitude parameter measurement system in the semi-constraint period. The performance of the laser directly determines the parameters of the measurement system. accuracy and reliability. [0003] During the live ammunition launch test of the shooting range measurement system, the laser is placed at the center of the front axis of the projectile. As we all know, the launch of its projectiles in conventional artillery is based on the ignition of gunpowder in the shell casing of the barrel. The driving mechanism of high impact force (acceleration) due to the high temperature and high pressure cause...
