This blog covers the day to day progress of water rocket development by the Air Command Water Rockets team. It is also a facility for people to provide feedback and ask questions.
We've updated our main website with more details and photos of the Acceleron V build. There is short video that shows a couple of the pressure tests of the staging mechanism.

There is still lots to do before the next NSWRA launch. We're currently working on the parachute deployment mechanisms. We decided to use two of our existing parachutes for the booster so we will save some time there.

Great rocket!!!
I wish I could make rockets like that! :)
I can't wait to see the video when this baby flies. I check in to your site regularly. Cool stuff!
Hi George,
Is nice see that you are making progress in your gigantic rocket,
I got a problem with my rockets because I don´t know how many weight must I put on the nosecone, the counterweight. The rocket weight is about 225-250g .
Good luck with your rockets!
Daniel
Hi Daniel,
The amount of weight you need to add to the nosecone does not depend on the overall weight of the rocket, it is dependent on the weight distribution. You need to add enough weight so that the center of gravity is about 1.5 times the body diameter ahead of the center of pressure of your rocket. The should give the rocket the right stability without adding unnecessary weight. Instead of adding more weight, see if you can position your fins further back or make them bigger. This may give you more performance.
