The invention belongs to the technical field of aerospace, and discloses a vertical and horizontal tail butt joint fairing connecting structure and an aircraft, a vertical and horizontal tail butt joint fairing skin is fixedly connected with a horizontal tail upper wall plate, a vertical tail left wall plate is fixedly connected with a vertical tail end rib, and an inserting plate is connected to the position, connected with the vertical tail end rib, of the inner side of the vertical and horizontal tail butt joint fairing skin; a base plate is fixedly connected between the vertical tail left wall plate and the vertical and horizontal tail butt joint fairing skin on the vertical tail end rib, an insertion cavity allowing the insertion plate to be inserted is reserved between the base plate and the vertical tail end rib, and the insertion plate is inserted into the insertion cavity and can slide in the insertion cavity. The outer surface of the vertical fin left wall plate outer surface base plate is flush with the outer surface of the vertical and horizontal tail butt joint fairing skin. According to the vertical and horizontal tail butt joint fairing, the skin and the vertical tail end ribs are in flexible connection, so that the fairing can have a certain deformation coordination capacity, deformation is limited by flexible connection to be further transmitted to a vertical tail structure, and then unreasonable deformation can be prevented from damaging the aerodynamic configuration and increasing resistance.

    本发明属于航空航天技术领域,公开了一种垂平尾对接整流罩连接结构及飞机,垂平尾对接整流罩蒙皮与平尾上壁板之间固定连接,垂尾左壁板与垂尾端肋固定连接,垂平尾对接整流罩蒙皮内侧在与垂尾端肋连接位置连接有所述插接板,垂尾端肋上在垂尾左壁板与垂平尾对接整流罩蒙皮之间固定连接有垫板,垫板与垂尾端肋之间留有供插接板插入的插入腔,所述插接板插入所述插入腔中并能在插入腔中滑动,垂尾左壁板外表面垫板外表面和垂平尾对接整流罩蒙皮外表面平齐。本发明中垂平尾对接整流罩蒙皮与垂尾端肋之间为软连接,使整流罩能有一定量的变形协调能力,软连接限制变形进一步传递到垂尾结构,进而能够避免不合理的变形破坏气动外形和增加阻力。
