The invention provides a lightweight control surface structure based on additive manufacturing. The control surface structure comprises a skin (1), a web (2) and a rudder shaft (3), the rudder is characterized in that the skin (1) is of a box body structure, the front surface of the box body forms a rudder surface appearance with a sweepback leading edge, the multiple web plates are sequentially arranged in the box body structure, the multiple corrugated web plates are distributed in the spanwise direction of the rudder surface from a rudder root to a rudder tip, the web plates are corrugated, and the corrugation direction extends from bottom to top. Control surface bearing and an integrated structure are achieved, and control surface aerodynamic loads are efficiently transmitted to a rudder shaft and an aircraft structure.
本发明提供一种基于增材制造的轻量化舵面结构,该舵面结构包括蒙皮(1)、腹板(2)和舵轴(3);其特征是:蒙皮(1)为箱体结构,箱体的前表面构成前缘后掠的舵面外形,多个腹板依次排列在箱体结构内部,多个波纹腹板从舵根到舵梢沿舵面展向分布,腹板形状为波纹状,波纹方向由下向上延伸。本发明实现舵面承载和一体化结构,舵面气动载荷高效传递至舵轴和飞行器结构。
