软翼飞行器以其优越的飞行性能和应用优势已渐渐成为新型飞行器领域的研究热点。针对软翼飞行器两点柔性连接的特殊结构,考虑软翼附加质量与两体间相对运动,提出了一种八自由度(Degrees Of Freedom,DOF)非线性动力学模型;分别仿真分析了模型在稳定滑翔状态下对马力变化、单侧下偏与双侧下偏操作的响应情况飞行特性,结果表明软翼飞行器的操纵动作会引起两体间不同程度的相对运动,进而验证模型的正确性与适用性。
Soft-wing aircraft with its superior flight performance and application advantages has gradually become the research field of new aircraft. Aiming at the special structure of two-point flexible articulation of soft-wing aircraft, a nonlinear dynamics model of Degrees Of Freedom (DOF) is proposed considering the additional mass of the soft-wing and the relative motion between the two wings. Stable gliding state of horsepower variation, unilateral bias and bilateral down bias operation response characteristics of flight characteristics, the results show that the soft-wing aircraft manipulation will cause two different degrees of relative motion between the two bodies, and then verify the correctness of the model and applicability.
