摘　　要：在弹箭飞行动力学模型中,阻力系数的识别是一项重要任务。通过给出利用弹道参数灵敏度函数识别阻力系数的数学方法,结合弹道测试数据在弹箭飞行过程中对阻力系数进行辩识,从而修正飞行动力学模型,提高计算精度。In the flight kinetic model of cannonball and racket, discriminating and identifying the resistance coefficients is the important task. Given the mathematics method of identifying resistance coefficients through sensitivity function of ballistic parameters, resistance coefficients are identified in the flight of cannonball and racket combined with ballistic testing data in order to revise the flight kinetic model and increase the calculating precision.
