摘　　要：针对现有箔条弹一般通过引爆或者射流的方式增加箔条的出口速度以实现箔条的快速散开的特性,提出了一种以高速旋转飞行器为箔条投放器、利用飞行器的直线速度和高速旋转离心作用增加箔条出口速度,以实现箔条快速散开的新方法。通过对箔条的空中受力分析,建立了箔条快速散开阶段的运动模型,并进行仿真分析。仿真结果表明:将高速旋转飞行器作为箔条投放器作的方法是可行的,且箔条具有良好的快速散开性能。In order to improve the initial velocity of chaff which is released by chaff cartridge based on detonating the dynamite or blasting form projectile commonly, a novel technique of chaff release is proposed, which is carried by aerocraft revolving around an axis at high speed. And the model of chaff motion in the phase of dispersing rapidly is established on the basis of the analyzing the influence of resistance, gravity and viscous force. Simulation results show that the method based on revolving aerocraft is efficacious and the chaff can disperse rapidly.
