So I see tons of designs out there that use BP charges along with their altimeters and all, but I am wondering if anyone has tried non-pyro methods.
I am currently in the process of designing a rather complicated dual deployment system that will use a compressed spring, and a solenoid shear pin type thing.
Compressed gases seem out of the question, because of the complications involved in holding them at pressure, and then releasing it. The weight of a pressure container and valve with some sort of electrical triggering just seems like way beyond the range one could launch in a rocket.
I suppose the other possibility when using a compressed spring, would be to use a burn string, but I would far prefer straight forward mechanical and electrical systems to anything that burns.
All ideas welcome.
Last thing, for reference, I am working with BT-70
