Bottle Rocket B

[daycd]

Wright state first was like 18 seconds on 50psi

Was this an official time? A windy day? That is an incredible time. I'm guessing that 12 seconds is where a lot of the good teams will end up. With the exceptional teams being nearer 14 seconds.

Individual or combined?

EDIT: Just saw your other post, y. By total, you mean combined, I assume.

From what I noticed from lunching bottle rocket, you have to have a windy day rocket and a non-windy day rocket. This is because when I use the mylar tube on a windy day the rocket can't gain height. However, when I use the T8 tubes I can get a lot higher. But if I use the T8 tubes on a non-windy day then the times are not as great as the mylar cones.

Does anyone have any suggestions for my rocket!

Huh, that's interesting. Is your mylar cone bending in the wind, causing it to fall short of what the T8 tube can achieve? I just have one rocket type for any scenario, having a mylar cone sturdy enough, but also light enough to maintain the best of best worlds.

Also, what times are you getting? I haven't tried T8 tubes this year yet, but I might just give them a go.

We have been struggling with building a competitive rocket. At our last invitational we were told that the nose cone is meant to be related to the center of gravity. To increase time in the air, exactly where should the center of gravity be? Is it where the egg is? Are we using the nose cone to balance the weight behind and in front of the egg?

using T8 tubes, I currently tested a rocket that got 10 seconds at 45 PSI

using 2 ft long mylar nosecone 11 seconds at 60 PSI

It was about 18.56 seconds combined, a little windy, and the best time was under 10, average was 3-5 seconds. Hope this helps.
