AI Technical Summary
⚠Technical Problem
Current spacecraft separation systems induce high impact on satellites due to the use of multiple discrete release actuators, which are costly and unreliable, especially for medium and large satellites.
⚗Method used
A multi-compartmental depression and separation device with a central structure, comprising coaxially arranged members, elastic means, and press-down assemblies, using non-explosive actuators for synchronized separation, reducing impact and cost through geometric simplification and single actuator operation.
🎯Benefits of technology
The device achieves lower shock transmission, reduced manufacturing costs, and increased flexibility in interface positioning, allowing for easy installation and preload, while minimizing impact on the satellite.

Abstract
We provide a multi-compartmental depressure separation device for spacecraft. [Solution] The multiple depressor separation device 1 comprises a central structure 2 comprising a first member 3 and a second member 4 arranged coaxially around an axis and configured to have relative axial movement, elastic means 7, 7' that contact the inner surfaces of the first member 3 and the second member 4, a removal bolt 8 connected to the second member 4, and an actuator 9 connected to the removal bolt 8 of the central structure 2 and connected to the first member 3 through a support 10; at least two inclined guides 11 projecting radially from the central structure 2, at least two arms 12 each having a first portion 12' and a second portion 12'', at least two connecting levers 16 having a joint 17, and at least two depressor assemblies 26 on the periphery of the device 1 having a depressor support 18 and a depressor portion 20.
