| 摘 要： | 针对新型半铰接式、摆振柔软的倾转旋翼机,建立了旋翼/动力舱/机翼气动弹性稳定性分析模型,并导出了系统的动力学方程。分析模型采用了当量铰、弹性约束的刚性桨叶和弹性机翼假设,采用Pitt-Peters动力入流模型计入了非定常气动力的影响。所建模型为进行新型倾转旋翼机大速度飞行时气弹稳定性分析奠定了基础。

| Abstract: | An analytical model of tilt-rotor/pylon/wing coupled aeroelastic stability is presented and the dynamic equations are derived for a new semi-articulated, soft-inplane tilt-rotor aircraft. Assumptions of equivalent hinge with spring restrained, stiff rotor blades and elastic wings are applied, and Pitt-Peters dynamic inflow model is taken into account in order to include unsteady aerodynamics. The model can be used for aeroelastic stability analysis of the new tilt-rotor aircraft in high-speed forward flight. |
