摘要
综述了自20世纪末至今以来航空发动机风扇叶片鸟撞问题在鸟体几何选型与建模、瞬态动力学数值分析方法、叶片鸟撞响应与损伤以及鸟撞关键试验技术等方面的进展,结果表明:当前国外在航空发动机叶片鸟撞击的研究已经进入深度应用阶段,而在国内仍然存在脉络不清,体系不明,支撑不足等现状。提出了未来研究应重点关注高精度鸟体模型、新材料叶片鸟撞、旋转状态下叶片鸟撞试验技术与鸟撞后发动机整机动态响应分析方法等问题。
The progresses made since the late 20th century in addressing bird strike issues on aircraft engine fan blades,covering aspects such as the geometric modeling of birds,transient dynamic numerical analysis methods,fan blade response and damage from bird strikes,as well as key bird strike testing techniques,were reviewed.The results indicated that foreign research on bird strikes on aircraft engine fan blades entered a deep application phase,while domestic research still faced challenges such as unclear research frameworks,undefined systems,and insufficient support.It’s also suggested that future research should focus on high-precision bird modeling,bird strikes on new material blades,bird strike testing techniques for blades in rotating states,and methods for analyzing the dynamic response of the entire engine post-strike.
