电磁场在RDX基混合炸药中的衰减和传播特性OA

In electromagnetic launch systems,the high-energy explosives carried by the projectile will have an im-pact on electromagnetic fields.Therefore,the attenuation mechanisms and propagation characteristics of electromagnetic fields in the presence of RDX-based mixed explosives were studied.The magnetic permeability and conductivity of RDX-based mixed explosives were tested.The propagation characteristics of the external electromagnetic field in RDX-based mixed explosives,including transmission path,wavelength,and penetration depth,were simulated using Ansys finite ele-ment software.The research results show that the attenuation of magnetic field in RDX-based mixed explosives is weak.The wavelength range of electromagnetic waves with different frequencies in RDX-based mixed explosives was calculated.Com-paring RDX-based mixed explosives with and without aluminum powder,it has been confirmed that the addition of alumi-num powder has a very weak effect on electromagnetic attenuation.It provides theoretical support for the stability of the electromagnetic field environment during the electromagnetic launch process.
