中文摘要：
对相同总体设计条件下的传统布局飞行器的机翼和连翼布局飞行器的机翼进行了静气动弹性特性和颤振特性的对比分析。重点开展了考虑弹性变形的情况下,两种机翼在提供相同升力的条件下,结构所承受的气动载荷的对比分析及气动导数随动压变化趋势的对比分析。分析结果表明：与传统布局机翼相比,连翼布局机翼具有更高的设计灵活性;在相同的结构重量条件下,连翼布局机翼较之传统布局弯曲和扭转刚度特性更好,并具有较高的颤振速度;弹性情况下连翼布局机翼升力线斜率随动压增大而增大,且这种增加梯度受到后翼弯曲刚度的影响。
英文摘要：
The analysis of static aeroelastic and flutter characteristics are performed on the traditional wing and the joined wing under the same general design condition.Taking elastic deformation into consideration,this study focuses on the comparative analysis of the aerodynamic load of the two wings under the same lift condition as well as the aerodynamic derivative changing with flight dynamic pressure.It can be concluded that the joined wing has more flexible design space than the traditional wing.The joined wing possesses better bending and torsion stiffness characteristic as well as higher flutter velocity than the traditional wing under the same weight condition.In the case of the elastic deformation,the slope of lift curve of the joined wing increases as the flight dynamic pressure increases and the bending stiffness of the aft wing has certain impact on the gradient of increase.
