Gravity Mechanisms

Hi Guys,

Because water rockets don't typically have the luxury of ejection charge delays and ejection charges, many people come up with their own mechanisms for detecting apogee to deploy a parachute. One of the things that we see quite often are designs for parachute deployment systems based on "gravity" mechanisms that attempt to detect apogee when the rocket tips over. Last week we flew a couple of experiments that show what actually happens to these mechanisms in flight to help people make better decisions when designing their own systems.

Here is a video of the experiment setup and a couple of flights:


We've also done a full write up here:

We have a few more mechanisms that we would like to demonstrate in the coming weeks. It would be fun to fly some of these in HPR rockets.

Nice video. I really like your micro lab setup, what a great idea!

Like the comment at the end of the second vid, "really long delay".... :wink:
