摘　　要：违规释放的空飘气球给飞机航行和地面人员带来严重安全威胁,研究其飞行轨迹特性,对于有效预防安全事故,合理处置空飘气球具有重要意义。综合考虑了气球浮力、重力、空气阻力、大气密度变化、风场变化等因素,对空飘气球进行了受力分析,建立了空飘气球的动力学和运动学模型,气球飘飞时的大气环境模型。利用计算机仿真,对空飘气球释放后的上升速度特性、上升高度特性、飞行轨迹特性进行了详细分析,并对比了不同阻力形式模型下的轨迹区别,验证了提出模型的有效性。Illegal releasing balloons bring serious threat to the safety of airplane flight and ground people,researching on its flight trajectory characteristics has important meaning to prevent accidents effectively and deal with the balloon reasonably.In this paper,the factors of the balloon buoyancy force,gravity,air resistance,changeable atmospheric density,varying wind are comprehensively considered,and then the dynamic model and kinematic model of the balloon,the atmospheric environment model are established.Using the computer simulation,the characteristics of ascending velocity,ascending height,flight trajectory are analyzed detailedly,and the flight difference under different air resistance are investigated,thus the effectiveness of the proposed model is illustrated.
