Problems solved by technology

[0015] Although the above-mentioned methods can realize the launch of multiple satellites with one arrow, there are certain deficiencies in all of them.
The method of axial support and axial separation is likely to cause mutual interference when the satellites are separated, especially when all satellites are separated at one time.

Embodiment Construction

[0024] Taking a tiny satellite of 100×100×300mm as the payload for illustration, the size of the launch vehicle fairing is 800×800×1550mm.

[0025] The accompanying drawing is a schematic diagram of the internal structure of a novel multi-star separation, unlocking and releasing device of the present invention. The unit includes:

[0026] Bracket [1], adapter [2], satellite track expander [3], connecting ring [4], the envelope size of the whole structure in the present invention is 800×800×750mm. During the launch phase, the carrying satellite is folded in the satellite orbit expander, and the satellite orbit expander provides support for the carrying satellite and bears various loads transmitted by the satellite; after receiving the deployment order, the carrying satellite is separated. The specific process of satellite separation is: satellite orbit unfolding The hatch door of the launcher is opened, and the five satellites are slid out along the guide rails inside the box ...

Abstract

The invention relates to a novel multi-satellite separating, unlocking and releasing device. Defects of varieties of separating, unlocking and releasing devices in the prior art can be overcome, and the problems that a separating device of a micro spacecraft in multi-satellite carrying and launching process is complex and high in cost are solved. The novel multi-satellite separating, unlocking and releasing device adopts an axial supporting manner and a radial separating manner, good mechanical environment of a carrying micro spacecraft in the launching step is guaranteed, and meanwhile, satellites can be prevented from mutual interference during separation and collisions after separation; the novel multi-satellite separating, unlocking and releasing device is simple in structure, convenient to modify and maintain and high in environmental adaptability, adopts modular design, and has the advantages of low cost, parts simplicity and high reliability.

Description

technical field [0001] This patent relates to a new type of multi-satellite separation, unlocking and releasing device, which is applied to the reliable separation between satellites (microsatellites, nanosatellites, pico-satellites, etc.) Background technique [0002] During the launching process of the spacecraft, the separation, unlocking and releasing device between the satellite and the launch vehicle is very important. It is necessary to realize the success of the satellite's unlocking, separation and release, and to provide the satellite with a reasonable separation speed. [0003] The star-arrow separation unlocking release device has the following functions: [0004] 1. Connect the satellite and the satellite bracket (rocket), provide support for the satellite during the launch process, bear various loads transmitted by the satellite, and ensure the reliable connection of the satellite and rocket; [0005] 2. Guarantee the reliable connection of the satellite and t...
