Abstract

The invention provides a link-type star-arrow separation mechanism, which includes an upper docking ring, a lower docking ring, a link-type belt locking mechanism, a tension spring assembly, a separation spring assembly, a travel switch and a separation switch, which are suitable for separation impact requirements. The tiny satellite less than 200g realizes the connection and fixation between the satellite and the rocket during the launch process, and realizes the separation of the satellite and the rocket after entering the orbit. The advantages of large tightening force and small unlocking impact.

Description

technical field [0001] The invention belongs to the field of satellite-rocket separation, and relates to a link-type satellite-rocket separation mechanism, which is especially suitable for the separation of micro-satellites with a separation impact requirement of less than 200g. Background technique [0002] The belt-type separation mechanism commonly used on David satellites uses explosive bolts for locking, which has a large locking force, but when unlocking, it needs to ignite the gunpowder inside the bolts, and the belt is unlocked by breaking the bolts. This method has too large unlocking impact The impact overload can reach up to 4000g or even higher. Due to the small size of the tiny satellite, the precision instruments carried are very sensitive to the impact generated by the satellite-rocket separation mechanism when the satellite-rocket separation mechanism is separated. The solar cells on the surface of the satellite are even close to the separation mechanism. May...
