航空飞行器冰雹冲击研究进展

Research Progress of Hail Impact on Aerocraft

航空飞行器在起飞、飞行中及降落三个阶段中随时可能遭到冰雹冲击,冰雹冲击会损伤飞行器部件,影响飞行器正常工作,甚至发生灾难性事故。为了保障飞行器在冰雹冲击时安全飞行,不少学者对冰雹冲击进行研究。从冰雹冲击实验、本构模型和数值模拟三个方面对冰雹冲击的研究工作进行归纳总结,最后对有待于进一步研究的问题进行展望。

Aerocraft was easy to impact with hailstone and might cause serious damages during its takeoff, flight and landing.Hail impact could cause severe damage to structural components, even catastrophic acci-dents.In order to ensure the aerocraft flying safely, many researchers studied hail impact.This paper summa-rized the research work from hail impact experiments, the constitutive model and numerical simulation.The fu-ture trend and further study were also discussed.
