Heres the stuff

Fins:

To make and design the fins for our rocket I used the NASA simulator. I found out that we would get the best fins if we made them out of cardboard. I also found out that the cardboard shouldn’t be too thick or it would increase the air resistance. I also discovered that the fins should be trapezoidal so that they stick out of the rocket to give it maximum stability, it would increase air resistance a little but that was ok because we traded that for stability and height. There were other detentions that I tweaked to help the rocket go a little higher but they didn’t help that much.

Summary:

I thought that overall our rocket was great. I am glad and surprised that we won the hang time competition and I think we had a great rocket. I’m surprised that our rocket won. It didn’t go higher than Aaron and Oliver’s but the parachute actually deployed. I know that if Aaron and Oliver’s parachute worked than we would have lost.

I think that we could have improved our rockets a little bit. We could have made the nose cone better so that we could fit the parachute but it still worked. Overall if we had more time we could have made our rocket a lot better. I’m still glad we won though.
