摘　　要：冰雹撞击试验系统是以压缩空气为动力的空气炮原理构建的,在设计时系统参数选择决定了试验的成功与否,同样在试验阶段时也需要根据技术要求选择各参数。文中利用一维等熵非定常气体的运动方程计算系统的各参数,并把所得参数作为设计和试验的参考数据。The hailstone impacting test system is constructed basing on the theory of air gun which energy is offered by compressed air. The aim of this experiment was to select parameters which have much importance to the success of the research. Kinematic equation of one-dimensional isoentropic nonsteady air was used to calculate system parameters for reference of design and experiment.
