The invention belongs to the field of structural design, and relates to a vibration reduction sand box structure of a helicopter horizontal tail. Comprising a sand box, a lower cover plate and an upper cover plate, the sand box is arranged at the outer side end part of the horizontal tail; the front end of the sand box is aligned with the front edge of the horizontal tail and extends towards the rear edge of the horizontal tail; the shape of the sand box is conformal with the horizontal tail; the interior of the sand box is divided into N cavities; n sand injection holes are formed in the upper end surface of the sand box and are respectively communicated with the cavity; and the upper cover plate and the lower cover plate are connected with the sand box so as to seal the sand box.

    本发明属于结构设计领域,涉及到一种直升机平尾的减振砂盒结构。包括:砂盒、下盖板、上盖板;所述砂盒设置在平尾外侧端部,砂盒前端与平尾前缘对齐并向平尾后缘延伸;砂盒的外形与平尾共形;所述砂盒内部分为N个空腔;所述砂盒上端面设有N个注砂孔分别与空腔连通;所述上盖板和下盖板与砂盒连接从而密封砂盒。
