Star-arrow point connection and separation module and its device

Abstract

The invention provides a satellite-rocket point type connection and separation module and device. The satellite-rocket point type connection and separation module comprises an upper through connection barrel, a lower through connection barrel, an explosive bolt, a separation spring and a loading nut. The upper through connection barrel and the lower through connection barrel are connected together through the explosive bolt. The free end of the upper through connection barrel is used for being connected with a satellite bottom plate. The portion, connected with the explosive bolt, of the upper through connection barrel is provided with the loading nut. The separation spring is arranged outside the upper through connection barrel and the lower through connection barrel in a sleeving mode and pre-tightened under the effect of the upper through connection barrel and the lower through connection barrel. The satellite-rocket point type connection and separation module and device are good in connection rigidity, low in impact force, high in adaptability, short in research period and low in cost.

Description

technical field [0001] The invention relates to the connection and separation fields such as star-arrow separation and inter-stage separation, in particular to a star-arrow point connection and separation module and its device. Background technique [0002] The connection and separation device is a mechanism used on rockets, missiles and spacecraft that has the functions of connection, unlocking and separation. During the flight, the separation connection device completes the unlocking and separation actions according to the prescribed order, and throws away those parts that have completed their missions (such as boosters, lower stages of rockets, rectification of vehicles and spacecraft, etc.). In order to achieve normal separation, the separation body is prevented from contacting again, so that the separation body has the required relative separation speed. [0003] With the increasing trend of small satellites at home and abroad, the interface between each satellite and ...

AI Technical Summary

Problems solved by technology

[0003] With the increasing trend of small satellites at home and abroad, the interface between each satellite and the carrier is quite different, and higher requirements are placed on the development cycle, cost and impact of the separation connection device. The traditional belt connection unlocking device series can no longer meet the current tasks. Requirements, there are shortcomings such as limited interface and high cost of mature products, and long development cycle of new research interface products.
