Abstract

The invention provides a pneumatic self-locking separation nut and a spacecraft and relates to the technical fields of carrier rocket separation, satellite and rocket separation and other frontiers ofscience and technology. The pneumatic self-locking separation nut comprises a gas generator, a gas cylinder, a housing, multiple segmented nuts and multiple unlocking balls. The outer wall of the gascylinder is in abutting connection with the inner wall of the housing, and the gas cylinder and the housing form a gas cavity. The gas generator introduces gas towards the gas cavity so as to drive the gas cylinder to move in the axial direction of the inner wall of the housing. The multiple segmented nuts are sequentially connected in an abutting mode to form an annulus through enclosure. Each segmented nut corresponds to at least one unlocking ball. One end of each unlocking ball is in abutting connection with the outer wall of the corresponding segmented nut, and the other end of each unlocking ball is in abutting connection with the inner wall of the gas cylinder. At least one annular groove for containing the multiple unlocking balls is formed in the inner wall of the gas cylinder. The pneumatic self-locking separation nut is simple in structure, the stuck problem in the unlocking process can be solved by arranging the unlocking balls, quick unlocking can be achieved through theseparation nut, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technological frontier technical fields such as carrier rocket separation, satellite rocket separation, etc., in particular to a pneumatic self-unlocking separation nut and a spacecraft. Background technique [0002] The separation nut is a connection unlocking device with axial connection and radial unlocking, which is widely used in the connection and separation of sections on spacecraft. The principle of separating the nut is mainly to cut a complete nut into parts, and use the ferrule to tighten the split nut. When separating, the ferrule and the split nut will move relative to each other, and the restraint will be released, and the split nut will be forced to open to achieve the purpose of unlocking. . [0003] At present, the separation nuts used in my country's launch vehicles and satellites are mainly connected by pyrotechnics to the separation nut unlocking device. This device can provide a very large connection f...
