Embodiment Construction

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and / or" includes any a...

Abstract

The invention discloses an inter-satellite pyrotechnic separation device. The inter-satellite pyrotechnic separation device comprises an inter-satellite wrapping belt, a plurality of clamping blocks and guiding limiting mechanisms, wherein the inter-satellite wrapping belt is formed by annularly connecting two strip belts through pyrotechnic separation elements; the multiple clamping blocks are discretely fixed to the strip belts and located on the inner circumferential side of the inter-satellite wrapping belt and used for axially locking a butt-jointing ring of a next-level satellite and a butt-jointing ring of a before-level satellite; and the guiding limiting mechanisms comprise guiding pieces, protective plates and extension springs. The inter-satellite pyrotechnic separation device has the position constraint capacity for the inter-satellite wrapping belt in the separation process and after the separation, the negative influence of the inter-satellite wrapping belt after being unlocked on the on-orbit attitude of the next-level satellite is completely eradicated or reduced, and the attitude regulate and control difficulty of the next-level satellite is reduced.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an interstellar pyrotechnic separation device. Background technique [0002] Multiple satellites with one rocket is a technology that uses one carrier rocket to simultaneously or successively send several satellites into the earth's orbit. One form of multiple satellites with one arrow is to connect multiple satellites in series and separate them one after another. In the series connection, the connection separation is usually realized by encapsulation between the satellites with larger mass. When the upper-level satellite reaches the orbiting condition, the tape is unlocked to separate the upper and lower satellites, and the unlocked tape is retained in the lower-level satellite. This separation method often makes it difficult to adjust the on-orbit attitude of the lower-level satellites, and the difficulty of attitude adjustment and control of the lower-level satellites is...
