Non-pyro system

Postby hakand2 » Wed Dec 19, 2018 5:26 pm

Hey guys, I am hakan and study at university as a mechanical engineer. Next year we are planning to attend HPR competition in Turkey. We have to do parachute system by non-pyro( which is called CO2 enjection charge ) we must not use any exploded system. That’s why we are going to use non-pyro. My question is that how can l assemble CO2 system in my rocket body ? And I want to design my system. Could you give me any advice for this ?
Thank you

Perhaps I am misreading the original question, but if your are looking for a completely ‘pyro-less’ system, most of those co2 systems are no good as they all require an e-match firing a small BP charge.

This is often an oversight that people claim pyroless, but it is more ‘minimal pyro’.

If you do not have access to pyro at all, you will most likely need a physical (e.g. servo) driven device of some sort.
