Abstract

The invention relates to the technical field of tactical missile shell section structures, in particular to a stringer housing which comprises a housing and a stringer, wherein the housing is rotary and comprises a covering skin and end frames located at both ends of the covering skin and integrally formed together with the covering skin; the stringer is connected with an inner wall of the housing in an axial direction of the housing. The housing of the invention is a rotary structure; the end frames and the covering skin form an integrated structure which has no projecting structure, can be completed by lathing, greatly shortens the processing cycle, and greatly improves the processing efficiency; positions of an upper end frame and a lower end frame are designed according to the size of an interface; the positions of the end frame and the covering skin adopt smooth transition, can be completed by lathing, greatly improve the processing efficiency, and reduce stress concentration. The stringer housing provided by the invention reduces the assembling difficulty and strength, effectively improves the assembling efficiency, also effectively reduces the weight of the missile structure, and improves the missile performance; the housing has high form-position tolerance grade, ensures aerodynamic shape of the missile, has attractive appearance, has no obvious splicing joints, and reduces the probability of appearance of rework events caused by appearance defects.

Description

technical field [0001] The invention relates to the technical field of tactical missile shell segment structures, in particular to a stringer shell. Background technique [0002] At present, the commonly used structures of the tactical missile shell segment mainly include the end frame-skin-stringer structure and the grid rib shell structure. [0003] The end frame-skin-stringer structure is mainly used in the body structure of tactical missile weapons. The processing precision is high, and the operation requirements for workers are high. The cylindricity of the shell and the parallelism of the upper and lower butt joint surfaces are poor. [0004] The grid rib shell is a triangular, rhombus or orthogonal grid structure arranged on the skin of the shell. The shell of this structure is heavy, the processing cost is high, the processing cycle is long, and the requirement for machining capability is relatively high. Contents of the invention [0005] (1) Technical problem...
