The invention discloses an aircraft elastic piece structure which comprises an elastic piece, one end of the elastic piece is connected with a tail cover, the other end of the elastic piece is connected with an outer adjusting piece through a force bearing ring, the connecting position of the elastic piece and the force bearing ring is located on the outer side of the connecting position of a spray pipe contraction section and a stress application barrel, and the other end of the spray pipe contraction section is connected with a spray pipe expansion section. The elastic piece is high in circumferential rigidity, and the radial deformation of the elastic piece is smaller than that of a sectioning elastic piece under the action of the same differential pressure load. The elastic pieces are high in bearing capacity, under the action of the same load, the load transmitted to the force bearing ring by the elastic pieces is smaller than that transmitted to the force bearing ring by the sectioning elastic pieces, and disturbance to the force bearing ring after the elastic pieces are loaded is small. The elastic sheet is large in structural rigidity, and a sectioned elastic sheet is replaced according to an equal-rigidity principle, so that the wall thickness of the elastic sheet can be reduced, and the weight reduction effect is achieved.
本发明公开了一种飞机弹性片结构,包括弹性片,所述弹性片一端与尾罩连接,弹性片另一端通过承力环与外调节片连接,弹性片与承力环连接处位于喷管收敛段与加力筒体连接处的外侧,所述喷管收敛段另一端与喷管扩张段连接。本发明的弹性片周向刚度大,在相同压差载荷作用下,弹性片径向变形较分瓣弹性片小。弹性片承载能力强,在相同载荷作用下,弹性片传递到承力环的载荷较分瓣弹性片小,弹性片受载后对承力环的扰动小。弹性片结构刚度大,按照等刚度原则替换分瓣弹性片,可以降低弹性片壁厚,起到减重效果。
