摘　　要：为获得空中目标的静电特性,分析了影响飞机静电场的主要因素,包括喷气式飞机燃烧室内的自由电子、正离子或负离子以及碳黑粒子.通过建立燃烧室内的荷电数学模型,采用仿真的方法对燃烧室的荷电特性进行了分析,得出了碳黑粒子是影响燃烧室荷电特性的关键因素,碳黑粒子的粒径及其荷电量对燃烧室荷电量和极性均有一定影响的结论.为进一步研究飞机机身荷电提供了基础.To obtain the electrostatic field property of an aerial target, the main factors influencing the plane＇s electrostatic field are analyzed, including the free electron, positive ion or negative ion, and the soot carbon particles in the jet firebox. Mathematical model of the jet firebox is established, the firebox charging properties are analyzed with the help of simulation. The results indicate that the key factor which influences the charging property of jet firebox is the soot carbon particle, and the particle diameter and its charge quantity influence the charge quantity and polarity of the jet firebox. This provides a basis for further research on charges upon jet fuselage cover.
