摘要
为了提高某型飞机机翼颤振速度,详细探讨利用副翼前缘配重提高颤振速度的方案.用MSCNastran对副翼前缘进行变配重重量和位置的振动、颤振计算分析.得到的结果有助于改善机翼的颤振特性,为机翼改进设计及飞机振动、颤振试飞提供参考.
To increase flutter speed of airfoil in aircraft engineering, the schemes that makes use of attached weights in leading-edge of aileron are discussed. The properties of vibration and flutter of the aileron with different weight and position attached weights in leading-edge are calculated.The results obtained can improve the flutter properties and provide the references for airplane modified design, vibration and flutter flight-test.
