直升机空中共振安全边界预报与验证

Prediction and Verification of Helicopter Air Resonance Safety Envelope

简略介绍了直升机空中共振建模思路,通过算例计算研究了确定直升机空中共振安全边界的分析技术,讨论了空中共振飞行试验验证方法。为更准确地预计空中共振安全边界,提出了需要进一步研究的内容和考虑的因素。最后,展望了空中共振分析方法的发展方向。

The modeling consideration of helicopter air resonance was introduced simply, the analy- sis technique of determining helicopter air resonance safety envelope was studied through calculation examples, and verification method of air resonance through flight test was discussed in this paper. In order to predict safety envlope more cxactly. further reaserch contents and factors need to consider were suggested. Finally it was looked into the furture devlopement of air resonance analysis tech-nique.
