Abstract

Based on test data such as fragment spherical target tests and fragmentation tests, empirical formula of fragment initial velocity and formula of velocity synthesis are used to calculate the lethal probability, and to obtain the variation law of the lethal area with angle, velocity, and explosion height. When the angle of impact is small, the ground isosurface of mnbvcxzlethal probability presents a C-shaped structure. As the angle increases, the opening of the C-shaped structure gradually decreases and eventually closes into a circular shape. The lethal area of fragments is greatly affected by changes in the angle of impact, and is relatively less affected by factors such as falling speed and explosion height. Under the condition of constant explosion height, the lethal area does not change significantly with the increase of falling speed, but there is a peak at the angle of 80° and falling speed of 550 m/s. Under the condition of constant falling speed, the lethal area shows a trend of increasing firstly and then decreasing with the increase of explosion height.
