Embodiment 1

[0035] This embodiment provides a satellite stacking architecture for batch launching of low-orbit satellite groups, such as figure 1 As shown, in a preferred embodiment, it includes an inter-satellite interface 30 and a satellite-rocket connection mechanism 40. A plurality of satellites 20 are overlapped and arranged on the rocket carrier 10 and are divided into left and right columns and arranged in a staggered manner. The shape of each satellite 20 and the same size, the rocket carrier 10 and the satellite 20 at the bottom are connected through the satellite-rocket connection mechanism 40, and the two adjacent satellites 20 are connected through the inter-satellite interface 30. The satellite-rocket connection mechanism 40 has the ability to provide power for the separation of the satellite and rocket. The elastic mechanism 41, on the one hand, the elastic mechanism 41 provides power for the in-orbit unlocking of the satellite 20, and on the other hand, plays a buffering rol...

Embodiment 2

[0044] This embodiment provides a satellite-rocket separation and unlocking module for the batch launch of a group of low-orbit satellites, which can be applied to the satellite stacking structure for the batch launch of a group of low-orbit satellites in Embodiment 1. Such as Figure 4 As shown, in a preferred embodiment, the star-rocket separation and unlocking module includes several sets of connection and separation devices 50 fixed on the rocket carrier 10, and each group of connection and separation devices 50 includes satellites connected to the rocket carrier 10. 20. Two pull rods 51 extending in the stacking direction, the connection between the pull rods 51 and the rocket carrier 10 (i.e. the root of the pull rods) are all provided with a first pyrotechnic device (not shown in the figure), and the ends of the two pull rods 51 ( Figure 4 The upper end) is commonly connected with a compression plate 53 located outside the terminal satellite 20, and a pressure bearing ...

Abstract

The invention provides a low earth orbit satellite batch launch satellite-rocket separation unlocking module and a satellite-rocket separation method. a plurality of satellites are stacked on a rocketcarrier, and the bottommost satellite is connected with the carrier through a satellite-rocket connecting mechanism. The satellite-rocket separation unlocking module comprises a plurality of connecting and separating devices fixedly arranged on rocket carrying, each connecting and separating device comprises two pull rods which are connected with the carrying and extend in the satellite stackingdirection, and first initiating explosive devices are arranged at the joints of the pull rods and the carrying. The tail ends of the two pull rods are jointly connected with a pressing plate located outside the tail end satellite, and a pressure bearing body is arranged between the pressing plate and the tail end satellite in a pressing mode. By arranging the pull rods, the pressure bearing body and the pressing plate, a plurality of satellites are pressed between rocket carrying and the pressing plate; when unlocking and separating are not conducted, the pull rods of the connecting and separating devices bear pull force and the pressure bearing body bears pressure, the connecting and separating devices conduct vertical limiting on the satellites, the structure is simple, and batch production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of aerospace satellites, and in particular relates to a method for separating an unlocking module from a group of low-orbit satellites and separating a satellite and an arrow. Background technique [0002] For launching satellites in batches, the safe separation of satellites and rockets in orbit is a very important issue. When the current satellite is launched in multiple satellites, each satellite and the distributor have an independent interface, the connection and separation method is simple, widely used and mature technology. With the rapid development of satellite constellations, the demand for the number of satellites is increasing day by day, and the demand even reaches tens of thousands, making the original independent launch method unable to meet the market demand. [0003] The traditional satellite launch connection and separation design has the following disadvantages: 1) Each satellite needs to...
