An autonomous measurement method of penetration angle based on magnetic detection

Abstract

The invention discloses a method for autonomously measuring the penetration angle based on magnetic detection. The technical solution provided by the present invention is: place a magnet on the inner axis of the penetrating bomb fuze, the fuze is coaxial with the missile body, and establish a magnetic field that is rotationally symmetrical about the axis of the missile body in the missile body, and the penetration angle is affected by the magnetic target plate , the direction of the magnetic field vector on the axis of the projectile is no longer parallel to the axis of the projectile, resulting in a deflection angle of the magnetic field, which changes with the penetration angle. , when the penetrating projectile penetrates the magnetic target plate, the magnetic field deflection angle is measured by the three-axis magnetometer, and the penetration angle is determined by using the numerical relationship between the penetration angle and the magnetic field deflection angle determined by the simulation analysis and experimental test. angle. The penetration angle measurement method is hardly affected by factors such as penetration speed, aspect ratio, and projectile mass, and can be used for the measurement of penetration angle of high-speed and large-penetration ammunition.

Description

technical field [0001] The invention relates to the technical field of penetration fuzes, in particular to a method for autonomously measuring penetration angles based on magnetic detection. Background technique [0002] In conventional warfare, in order to maximize the damage to the enemy's important military facilities buried in steel armor, reinforced concrete and other protective measures, the attack on these military targets is mainly completed by intelligent hard target penetrating weapons. Penetrating bombs must Capable of penetrating multiple layers of hard targets. Most of the studies on penetrating multi-layered hard targets are based on vertical penetration, but in practical applications, when penetrating projectiles penetrate, the penetrating projectiles are not only affected by longitudinal resistance to reduce the speed of the projectile body, but also by lateral resistance. The projectile body is inclined, and the penetration of the penetrating projectile on ...
