摘要
航空飞行器在飞行过程中容易和冰雹粒子发生碰撞,并由此造成撞击损伤.因此有必要开展航空飞行器在冰雹环境中的撞击试验。文中介绍了一种冰雹撞击试验系统的工作原理,即利用气体炮对冰雹弹丸加速,加速后的冰雹弹丸和飞行器产生高速撞击。利用该系统可对航空飞行器在冰雹类粒子高速撞击下的损伤进行评价和寿命预测。
Aerocraft is easy to impact with hailstone and may cause serious damages during its flight, so it＇s necessary to investigate hail impact on aerocraft by trial system. A trial system of hailstone impact is introduced. This system is designed with a gas-gun to accelerate hailstone, with which the hail will impact the craft surface with a high speed. This system could provide datas for evaluating the aerocraft material deface and forecasting validity time after hail impact.
