Research On Low Collateral Damage Anti-UAV Ammunition Technology

This article is based on the interception of the "low and small" rotor drone,and the direct firepower strike will cause the background of attached damage to the ground personnel and equipment.As a killing element,the warhead is equipped with a delayed device and a self-destructive agent to ensure that the warhead effectively kills the drone within 300 m and does not cause damage to the personnel other than 350 M.Based on the target damage evaluation method and fault tree analysis of the aircraft,the "low and small" rotor drone was analyzed,and the damage level was determined in different circumstances,and the ammunition was designed to design the ammunition.In order to solve the problem of the low attachment of the warhead,the extension medicine was installed in the rear half of the warhead,and the front end was equipped with a self-destructing medicine.When the warhead flight exceeded the kill range,the extended medicine was burned and the warhead was detonated.Based on the structure of the bullet and the material,the warhead design is designed to establish the target board model of the warhead model and the use of the drone’s damaged parts.Based on the Lagrang daily algorithm,through the display of dynamic simulation When the angle is less than 45 °,it can effectively destroy the drone.Based on the coupling model of air-air based on the external trajectory theory,calculate the force of the warheads under different Mach,find the bullet-shaped coefficient of the warhead designed in this article.At the time,the kinetic energy at 350 m is too high,which will cause damage to personnel.At the same time,the safety of the motion in the warhead and the stability of flying in the air.Proposed the loading plan of the self-destructive agent,using the S-ALE algorithm for simulation to solve it.According to the super-pressure peak curve of the spontaneous destruction of the warhead and the speed attenuation of the speed of the breaking,the criteria for the reference personnel damage are carried out on the low-attachment damage characteristics of the ammunition designed in this article.Verification.Through the design demonstration,the low-attachment damage ammunition scheme proposed in this article is feasible,and it is of guiding significance for reducing the use of direct firepower to crack down on "low and small" drones.
