Aiming device for explosively formed projectile warhead

Abstract

The invention discloses an explosive forming projectile warhead aiming device which is suitable for explosive forming projectile warhead test aiming. The aiming device comprises an optical aiming mirror housing, a fixing seat, a U-shaped groove, a rectangular guiding rail and a base, the aiming device is characterized by further comprising an objective lens, a converging lens, a relay lens and aneyepiece group, wherein the objective lens, the converging lens, the relay lens and the eyepiece group constitute an optical path system from left to right, the entire optical path system is installedin the aiming mirror housing in a sealed mode, the inner concave face of the U-shaped groove is downward, the aiming mirror housing is fixedly connected with the upper surface of the U-shaped groovethrough the fixing seat, the shape of the rectangular guiding rail is matched with the U-shaped groove and is located in the inner concave face of the U-shaped groove to be closely attached to the concave face, and the rectangular guiding rail is located on the upper surface of a trapezoidal base and is fastened by screws. Under the test condition of the high blast height (charging caliber of 1000times) of an explosive forming projectile warhead, the aiming device is used for aiming at an impact point of an explosive forming projectile, thus the impact accuracy of the explosive forming projectile can be significantly improved, long-distance off-target is avoided, the test efficiency is improved and the test cost is saved.

Description

technical field [0001] The invention belongs to the technical field of ammunition testing, and mainly relates to an aiming device, in particular to an aiming device for a warhead of an explosively formed projectile. Background technique [0002] Due to the advantages of large aspect ratio, high specific kinetic energy, insensitivity to explosion height, and strong anti-interference, explosively formed projectiles are widely used in fields such as terminal-sensitive ammunition and anti-medium-thick armored vehicle ammunition. Under explosive loading, the liner material flips and deforms under the conditions of high temperature, high pressure, and high strain rate, and finally forms an explosively formed projectile. This process involves elastic-plastic deformation, material failure, and plastic flow, and the physical process is very complicated. . The commonly used drug-mask design process is as follows: first, determine the size constraints of the drug-mask through engineer...

AI Technical Summary

Problems solved by technology

Under long-distance test conditions, if the adjustment of the impact point of the explosively formed projectile is inaccurate, it is likely to cause the explosively formed projectile to miss the target. The occurrence of the missed target situation not only increases the test cost but also reduces the test efficiency, which has a great impact on the development process. negative effect

According to literature research, at the present stage of explosively formed projectile warhead tests, the optical sight on the rifle is used to adjust the impact point of the projectile in most cases, and there is no special aiming device for adjusting the impact point of the explosively formed projectile, so the target is missed The condition occurs more frequently
