Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Successful 2 stage flight with new booster

Post by dongfang » Sun Oct 26, 2008 1:34 pm

Hi,

I have been working on this for some time... after thinking up the simple Gardena staging mechanism, I had no problems getting it to work with a simple, 22 mm nozzle booster with lots of thrust. But with a larger, heavier, smaller nozzle (17 mm), it just wouldn't separate.

I have modded the staging mechanism now, making it able to trigger with less thrust. Here are the pictures of the first successful flight with it.

Unfortunately my FlyCamOne went dead and I have sent it back to where I got it from (I think I will withdraw my recommendation of that pile of junk). So, no onboard video on this flight.

Regards
Soren

Very pretty photos! It looks like a beautiful flight, and you captured all phases on camera! Really great work! Too bad about the onboard video. I think the videos from the rocket are the coolest part, so it really sucks that it didn't work. I would have loved to see the staging from onboard.
