Problems solved by technology

[0003] Existing protection devices for explosive bolts mostly adopt the form of safety boxes or protective baffles. The baffles are designed to absorb kinetic energy and block the free ends that fly out when the explosive bolts are exploded and separated. Although it can effectively reduce the redundant The impact of objects on the cabin, but the impact of the impulse generated during the explosion on other surrounding structures is still relatively large, and its structure is often complex and heavy, with low reliability, which is not suitable for the lightweight and high reliability requirements of space missions

Abstract

The invention relates to the technical field of aerospace, in particular to an explosive bolt buffering device which comprises an installation base, a protection shell cover and an axial buffering device. An installation groove for installing an explosive bolt and the axial buffering device is formed in the installation base. A through hole for the explosive bolt to pass through is formed in the installation base. The protection shell cover is fixedly arranged on the installation base and can cover a groove opening of the installation groove, and the protection shell cover and the installationbase form a closed space together. The axial buffering device is arranged in the closed space. The effective buffering effect on instant large-impact loads is achieved, and the impact degree of the explosive bolt on an upper-stage cabin section in the stage separation test using process is remarkably reduced; the explosive bolt buffering device has the advantages of being small in part number, simple in structure, good in machining process, low in cost, convenient to install, compact in structure, light in weight, high in reliability, good in modularization compatibility and suitable for various aircrafts.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an explosion bolt buffer device. Background technique [0002] Explosive bolts are mostly used for inter-stage separation in the aerospace field, but in actual use, after the explosive bolts are installed, the length of the explosive bolts exposed outside the cabin is long, and multiple processes such as assembly and painting are carried out in the cabin. A little carelessness in the process of circulation is very likely to bruise and scratch the explosive bolt, and there is a safety hazard that the explosive bolt will detonate accidentally; on the other hand, the explosive bolt may produce high-speed debris after detonation, so protective measures need to be installed when using it Ensure that the wreckage when the bolt explodes and disconnects does not damage the surrounding structures and equipment. In addition, because the explosive separation of the explosive bolt is com...
