Launch Day #5
Today was our 5th launch day. It was a very unsuccessful day. Going into this launch we thought that we could have accomplished our goal if we modeled our rocket exactly the same as our previous rocket that flew over the building. We ran into one small problem, there was no string to attach the parachute to the rocket. We also learned today that we would have to somehow leave on cone attached to our rocket which would weight our rocket down and draw it to the ground faster. Our first launch was a failure in itself. The pump didn't pump pressure into the bottle and was stuck on there for a good 5 minutes. We then had to launch it again. We pumped 90 psi into our rocket and it was about 1/2 way full of water. Our time was 4.7 seconds which was a disappointment not only because our time was so low but also because all of our fins came off. We figured out that our time was so low because our parachute didn't deploy because our cone was too tight. Our next launch we decided to launch it without fins. Surprisingly it lasted a good 9.2 seconds but that was only because our cone wasn't attached to our rocket. That launch we again pumped it to 90 psi and it was 1/4th of the way full. Unfortunately today we didn't achieve our goal of 10 seconds which resulted in a major failure.

I believe that you guys did a great job, considering that you had to recreate a rocket in such a short amount of time. The mere fact that you guys were able to keep your rocket in the air for 9.2 seconds is an accomplishment, even if it didn't count. You guys sure did have an interesting and exciting journey throughout this project and during today's launch. Congratulations on a great project and admirable perseverance! :)
ReplyDeleteWOW!!! You guys are so good at this. Good try. That was soooo close. Did better than my group haha. I liked your information and think you guys did a great job overall (:
ReplyDeleteI agree that on the final day, there was a major lack of supplies (duct tape, string, cardboard, etc.), which left all of the groups scrounging for replacement supplies and ideas. I know that this made a big difference on all of the groups' launches. If all of the groups had an adequate amount of supplies, then I'm guessing more then half of the class groups would have achieved 10 seconds or higher. I'm sorry for your final disappointment. But as Tiare said, you showed a lot of perseverance and hopefully had some fun creating rockets in the process.
