摘要

面对“低慢小”无人机及蜂群威胁，转管机枪凭借高射速、持续火力优势，成为核心末端防御装备。但传统命中概率模型忽视高射速下身管旋转产生的离心、科氏惯性力对弹丸初速的动态影响，导致预测偏差显著。通过对命中概率的关键影响因素进行系统分析，以离心、科氏惯性力为切入点，分解弹丸初速的轴向、向心分量，结合身管旋转切向速度推导初速修正公式，融入外弹道模型构建命中概率修正模型；基于QT框架开发仿真系统，支持参数配置、弹道3D可视化及多工况命中概率计算。仿真与实验结果表明：针对大疆精灵4与奋斗者VTOLmini两类典型无人机目标，系统计算结果与实弹实验数据平均相对误差为7.36%，最大相对误差为13%，显著提升了转管机枪武器系统的命中概率模型精度，可有效支撑反无人机武器系统作战效能评估。

Abstract

In response to the growing threat posed by“low-altitude

slow-speed

small-size”(LSS) drones and drone swarms

Gatling guns have emerged as a key terminal-defense weapon system due to their high rate of fireand sustained firepower. However

conventional hit probability models neglect the dynamic influence of centrifugal and Coriolis inertial forces--induced by rapid barrel rotation at high firing rates—on projectile muzzle velocity

resulting in significant prediction errors that compromise precision interception capability. A systematic analysis of critical factors affecting hit probability is conducted

with centrifugal and Coriolis effects serving as the foundation for decomposing the axial and radial components of muzzle velocity. A corrected muzzle velocity formulation is derived by incorporating the tangential velocity of the rotating barrels and integrated into an external ballistic model to establish an enhanced hit probability model. Furthermore

a simulation system based on the Qt framework is developed

enabling parameter configuration

3D trajectory visualization

and multi-scenario hit probability computation. Simulation and live-fire experimental validation demonstrates that

for two representativeUAV targets (DJI Phantom 4 and Fendouzhe VTOL Mini)

the average relative error between the system's calculated results and the live-fire measured data is 7.36%

with a maximum relative error of 13%. This work thereby significantly improves the fidelity of hit probability modeling for Gatling gun-based anti-UAV weapon systems

and provides robust technical support for the operational effectiveness evaluation of such systems.
