The invention discloses a wing with a trailing edge having spanwise-chordwise deformability, and belongs to the field of structural design of morphing aircrafts. The wing is composed of a front edge, a wing box and a deformation rear edge. The deformation trailing edge system is a core component of the deformation wing and is composed of a deformation trailing edge compliant mechanism, a steering engine-connecting rod driving system and a sensing system. Wherein the trailing edge compliant mechanism is filled with a hyperelastic body to form a flexible transition area, so that the wing has large spanwise deformability. The driving system comprises a steering engine, a steering engine rocker arm, a connecting rod and a long shaft to drive the trailing edge to deform to change the bending degree of the wing, so that the wing has large chordwise deformation capacity. The sensing system comprises a Hall angle sensor, a base of the Hall angle sensor, a rubidium magnet and a supporting base of the rubidium magnet, and therefore steering engine rotation angle measurement is achieved. According to the technical scheme, the whole trailing edge deformation process is continuous, the skin surface is smooth and seamless, the three-dimensional torsion capacity is achieved, and certain bearing capacity is achieved.
本发明公开了一种后缘具有展向‑弦向变形能力的机翼,属于变体飞行器结构设计领域。本发明的机翼由前缘、翼盒、变形后缘构成。变形后缘系统是变形机翼的核心部件,由变形后缘柔顺机构、舵机–连杆驱动系统和传感系统组成。其中后缘柔顺机构中填充有超弹性体,以形成柔性过渡区域,从而使机翼具有展向大变形能力。驱动系统包括舵机、舵机摇臂、连杆和长轴,以驱动后缘变形改变机翼弯度,从而使机翼具有弦向大变形能力。传感系统包括霍尔角度传感器及其基座、铷磁铁及其支撑座,从而实现舵机转角测量。本发明技术方案后缘变形全过程连续,蒙皮表面光滑无缝,具备三维扭转能力,并具有一定的承载能力。
