The typical requirements for satellite release solutions from a launcher in SPACE - by Sébastien

Let’s talk about solutions for releasing satellites from their dispensers and releasing satellite appendixes like antennas or solar panels.

What are the typical requirements for satellite release solutions from a launcher?

In orbit deployment is one of the most critical functions operated during the launch sequence.

And the device used for Hold and Release shall fulfil very high standards of requirements:

 

  • A very high tensile requirement in a reduced space.
  • An extreme reliability requested in hard environments.
  • A limited level of shock required by the vicinity of the payload.
  • And a perfect synchronicity in particular in a case of multi-point release.

 

We, at Pyroalliance, benefit from a huge product heritage in pyrotechnic separation solutions.

Our solutions are flight proven with more than 10 000 separation nuts delivered in our history.

What is the principle of a solution based on pyrotechnic nuts for space separation?

The principle of pyrotechnic separation solution is simple: design a separation nut to hold a bolt.

And, when receiving an electrical command, to trigger the motion of internal parts that will release the bolt.
