Example Embodiment

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The branched housing separation structure of the present invention is a ring closed structure, such as figure 2 A partial cross-sectional view showing the cutting separation structure of the present invention is shown. The branched housing separation structure includes: the separation housing 1, the ring-to-axis shroud 2, the axial shroud 3, the T type cover 4, the flexible tone cable assembly 5, and the T-type Explosion assembly 6. At a predetermined separation of the circumferential outer side of the separation housing 1, there is a ring-to-preset weakening groove 7, and the axial preset shackle groove 8 and T type prefabricated groove 9, image 3 Indicated.

[0021] At the upper and lower end faces of the separation housing 1, the flexible tube assembly 5 is mounted in the casing corresponding to the circumferential position of the groove 7 by the ring-to-circumres....

Abstract

The invention discloses a structure for shell separation between missiles and rocket stages, comprising a separation shell (1), a circumferential shield (2), an axial shield (3), and a T-shaped shield (4) , the flexible detonating cord assembly (5) and the T-shaped detonating assembly (6); the circumferential shield (2), the axial shield (3) and the T-shaped shield (4) respectively connect the corresponding detonating cord assembly It is fixed on the inner side of the separation shell (1) to form a continuous and interlinked flexible detonating cord cutting structure in the circumferential and axial directions. The invention arranges flexible detonating cord components in the circumferential and axial ways of the separation shell, and connects them through the T-shaped detonation transmission component, which can combine the two operations of flame exhaust and interstage separation, and cut the cutting shell instantly at the same time The number of petals makes the separation sequence simple, reduces the separation links, and has a simple and reliable structure.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structures, in particular to a structure for shell separation between missiles and rocket stages. Background technique [0002] The shell of the missile refers to the visible external structure of the missile or rocket. It is the main part of the missile body to bear the force and maintain the external contour. The shell is equipped with various components and its brackets. It is generally in the shape of a hollow cylinder or a round table . After the projectile is launched, it is necessary to separate the segments that have completed the task by cutting. Generally, there are two kinds of separation devices: point type and linear type. Compared with the point type separation device, the linear separation device has the advantages of fewer components, simple structure and high reliability. [0003] The separation work before and after the operation of the current rocket two-stage engine includ...
