Parachute Detachment Mechanism

Postby air.command » Fri Mar 20, 2009 8:11 pm

In chatting to one of our water rocketeer friends (Mat G.) in Tassie this week, he described how his rocket got stuck in a tree flying one of the computers. I thought that the flight computer should at least be able to try to help in such a situation. Everyone loves a rocket eating tree right?

We put together a Parachute Detachment Mechanism prototype (DetMech) that allows the rocket to automatically let go of the parachute cord after a predetermined time.

The full details of the mechanism are available here:

We want to test fly it to see how the clamp holds up under high speed deploys. ... yup just another excuse to fly more rockets. :)

That seems like such a simple idea!
I guess no-one expects their rocket to get caught in trees, power-lines, etc.
The timer could also incorporate a beeper

The timer already contains a beeper to help locate a lost rocket, but I want it to also start beeping perhaps 10 seconds before it drops so that you can either get ready to catch it (preventing hard landings) or get out of the way. (preventing hard landings on ones head)

I watched your recent video and this is an awesome idea. The idea is incredibly simple, a great example of thinking outside of the circle.

When it comes to power lines a long pole would be a VERY bad idea!! LOL

This is a great idea though.
