SEPARATION DEVICE FOR SPACECRAFT AND A METHOD FOR SEPARATION

摘要

The invention relates to a separation device (1) for a spacecraft or launcher. The separation device (1) comprises an inner housing (2) divided into at least two portions locked to each other by a locking device (3) in a locking position. The locking device (3) is arranged to move between a locking position and a releasing position. The separation device (1) comprises an initiator (5) comprising means for providing high pressure fluid to an expansion chamber (6) when the separation device (1) is switched from a locked state to a released state. The high pressure fluid in an expansion chamber (6) moves the locking device (3) from the locking position to the releasing position when the separation device (1) is switched from the locked state to the released state. The separation device (1) comprises a dampening arrangement (8) arranged to attenuate a peak load when the separation device (1) is switched from the locked state to the released state.
