The utility model belongs to the field of aircraft structure design, and particularly relates to a high-rigidity
shear angle sheet structure which comprises a turned-over edge, a web plate, vertical ribs and edge strips. The
flange, the vertical ribs and the edge strip define a whole ring structure, the web plate is integrally connected to one end of the whole ring structure, the
flange is located on the outer side of the whole ring structure, the two sets of vertical ribs are symmetrically arranged on the two sides of the
flange, and the edge strip is correspondingly arranged on the inner side of the whole ring structure; the outer walls of the vertical ribs are connected with the
stringer, and the vertical ribs are arranged between the adjacent vertical ribs on the two sides of the
stringer. The turnup, the web plate, the vertical rib, the edge strip and the supporting column are designed to be equal in height at the notch of the
stringer, so that a thin
neck structure is avoided. When the load is large, the phenomenon of
stress concentration on the shearing angle piece is avoided. The rigidity of the wing rib at the position of the shearing angle piece is improved by changing the structural form among the traditional wing rib shearing angle piece, the edge strip and the supporting column, and then the structural strength requirement is met.
