The invention designs a distributed seamless active flexible wing. The wing is composed of a plurality of independent wing sections, the camber of each wing section can be independently changed in a distributed mode, and each independent variable-camber wing section is composed of a steering engine, a segmented hinged wing rib and a sliding skin. Every two adjacent wing sections are connected through the corresponding flexible film, so that deformation between the distributed variable-camber wing sections is continuous and smooth. Compared with a traditional airliner wing, the distributed active flexible deformation scheme is adopted, through independent flexible deformation of each wing section, the functions of a traditional flap and a traditional aileron are achieved, the mechanism complexity of the wing is reduced, and the weight of the wing is reduced; on the other hand, because the whole wing is seamless, no gap is generated when the control surface acts, airflow separation generated by the gap is avoided, the aerodynamic efficiency is improved, meanwhile, the aerodynamic noise is weakened, and the method is a very potential seamless control surface control mode in the future.
本发明设计一种分布式无缝主动柔性机翼。该机翼由多段独立的翼段组成,各翼段可独立分布式地改变弯度,每个独立的变弯度翼段由舵机、分段铰接翼肋、滑动蒙皮组成。且相邻的两个翼段之间由柔性薄膜连接,使得分布式变弯度翼段间的变形连续光滑。相较于传统客机机翼,本发明采用了分布式主动柔性变形的方案,通过各翼段的独立的柔性变形,实现了传统襟翼、副翼的功能,减小了机翼的机构复杂度,减轻了机翼重量;另一方面由于机翼整体无缝隙,在舵面作动时不会产生间隙,避免了由间隙产生的气流分离,提高了气动效率,同时减弱了气动噪声,是未来一种十分有潜力的无缝操纵舵面的方式。
