The invention relates to the technical field of spaceflight, in particular to a carrier rocket, an initiating explosive cutting cable protective cover and an assembly of the initiating explosive cutting cable protective cover. The initiating explosive cutting cable protective cover comprises four cover sections, and the extending direction of the end face of each cover section is the same with theextending direction of one diameter A-A of the initiating explosive cutting cable protective cover; two cover sections are symmetrically arranged by taking the other diameter B-B of the initiating explosive cutting cable protection cover as the symmetry axis, and the diameter B-B is perpendicular to the diameter A-A; the other two cover sections are respectively inserted into a gap between the two cover sections which are symmetrically arranged by taking the diameter B-B as a symmetry axis; a gap with a certain distance is formed between the end faces of every two adjacent cover sections, and the inner surface of one cover section and the outer surface of the other cover section adjacent to the cover section are overlapped to a certain extent. According to the initiating explosive cutting cable protective cover, the requirement for a cabin space of initiating explosive cutting cable protective cover installation can be lowered.
本申请涉及航天技术领域,尤其涉及一种运载火箭、火工切割索保护罩及其组件,其中,火工切割索保护罩,包括:四个罩段,每个罩段的端面的延伸方向均与火工切割索保护罩的一条直径A‑A的延伸方向相同;其中,两个罩段以火工切割索保护罩的另一条直径B‑B为对称轴对称布置,直径B‑B与直径A‑A垂直;另外两个罩段分别插入以直径B‑B为对称轴对称布置的两个罩段之间的间隙中;相邻的两个罩段的端面之间形成有一定距离的间隙,并且其中一个罩段的内表面和与之相邻的另一个罩段外表面具有一定的交叠。本申请提供的火工切割索保护罩可以降低安装火工切割索保护罩对舱段空间的要求。
