Embodiment approach

[0031] Such as Figure 1-3 A specific implementation of the shown non-pyrotechnic separation device based on explosive bolts includes:

[0032] At least one explosive bolt 16 is provided with an air cavity 3 for containing high-pressure gas inside;

[0033] At least one high-pressure gas cylinder 12 communicates with the air cavity 3 of the explosive bolt 16 through at least one pipeline 15, and is used to transport the high-pressure gas stored inside to the air cavity 3 of the explosive bolt 16 through the pipeline 15 and apply force to the explosive bolt 16 to separate it.

[0034] The front end of the high-pressure gas cylinder 12 is also provided with an inflation valve 11. Before the launch of the carrier rocket, the high-pressure gas cylinder 12 is charged with high-pressure gas (the high-pressure gas is about 30-90Mpa) through the inflation valve 11 in advance, thereby storing the high-pressure gas at a high pressure. In the gas cylinder 12, at least one high-pressure...

Abstract

The invention relates to the technical field of aerospace equipment, in particular to a non-pyrotechnic separation device based on an explosive bolt. The non-pyrotechnic separation device comprises atleast one explosive bolt and at least one high-pressure gas cylinder, wherein a gas chamber for accommodating a high-pressure gas is arranged in the explosive bolt; and the high-pressure gas cylinderis communicated with the gas chamber of the explosive bolt through at least one pipeline, is used for conveying the high-pressure gas stored in the high-pressure gas cylinder to the gas chamber of the explosive bolt through the pipeline, and applies an acting force to the explosive bolt to divide the explosive bolt. The non-pyrotechnic separation device based on the explosive bolt, provided by the invention, is reusable and low in cost and does not generate harmful gases.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a non-pyrotechnic separation device based on explosive bolts. Background technique [0002] The traditional separation of rocket sections, whether it is separation between stages or fairings, often uses explosive bolts to separate, and the pyrotechnics are one-time use and expensive. Not only the separated pyrotechnics are used once, but also the related supporting products are all Single-use products such as detonating cords, manifolds, detonators, etc. The chemical energy generated by the detonation of the detonator is transmitted to the separation pyrotechnics through the manifold and the detonating cord for detonation and separation and unlocking. Since all the pyrotechnics such as the main charge and the secondary charge are exhausted after one detonation, the whole set of separation After the unlocking device is used once, it cannot be reused, which leads to an...
