| 摘 要： | 某先进民用支线飞机采用超临界机翼设计，跨音速颤振特性是超临界机翼的重要关键技术之一。颤振模型风洞试验是民机研制阶段最有效的跨音速颤振特性适航验证试验。本文设计了某民机超临界机翼跨音速风洞颤振试验模型并进行了颤振风洞试验，根据试验结果并结合亚音速颤振分析和压缩性数值分析，得到了超临界机翼的跨音速颤振压缩性修正曲线。研究表明，超临界机翼跨音速颤振速度最大压缩性修正系数较小，风洞试验结果与理论分析吻合较好，试验结果可以用于飞机的适航取证。

| Abstract: | An advanced region jet is designed with supercritical wing. The transonic flutter characteristic is one of the critical techniques of supercritical wing. The wind tunnel test of flutter model is the effective test for civil aircraft airworthiness compliance. A transonic flutter model is designed and used to research the transonic flutter of wing through the model wind tunnel test. Meantime, the test result is used to evaluate the academic flutter calculation for the model, including the subsonic flutter calculation and lift slope analysis. Comparisons show that the test result is satisfied with the theoretical analysis well and the maximal Mach effect factor is small. The test result is applicable to airworthiness compliance certification. |
