Makana and I had to build an entirely new rocket because of the devastating lost of our first rocket (which is still snug atop Midkiff). We also made a larger cone with mass made with marbles, cotton balls, and strips of plastic bags. Another change was made to the parachutes design. We made the parachute wider to catch as much air as possible.
After the alterations were made (and Makana removed her pearly white shoes to avoid getting them dirty), we went to launch. We had many failed trials, but with more water and pressure (and less marbles) the rocket launched successfully and stayed in the air more than 10 seconds.
Aside from alterations we made to the rocket and parachute, in the middle of our failed trials, Makana and I made the string that attached the cone to the rocket longer so that the parachute could deploy. Overall, (aside from the stained wet shirts and muddy feet) today's launch went great and we succeeded the requirement of 10 seconds!!!
We plan to shoot the rocket again to see if it can stay in the air longer.
Hey guys i really like this post its really organized and the pictures
ReplyDeleteare great too! Congrats on making the time requirement! I think that
the water and greater pressure really helped, which I didnt think was going to work.Great going :D
Hey makana and ian:) you guys had a good launch today:) i watched both of your launches and i bet your happy you didnt lose this rocket. Really good post and pictures guys.
ReplyDeleteHey Ian, good job on the post. I think you should mention how we also used different amounts of water to get the best launch and how we learned that by putting more water, our rocket went higher. Also, with a greater height, our rocket had more time to deploy it's parachute which had a great effect on the overall time because when we didn't put as much water, the rocket didn't go as high, it didn't have enough time to deploy the parachute, and overall the time did not meet the requirement. But other than that, REALLY GOOD JOB :)
ReplyDeleteI love the post. The pictures are a very nice touch. The marbles were an interesting idea. I never thought of that. I really like your thinking regarding the parachute. Definitely making the parachute wider helps the rocket. Im glad that with a little trial and error, you guys used excellent problem solving skills and adapted your rocket. Im SOOO happy you guys made the time!! Kailly and I tried more water and it didn't seem to work but that could have been because of other contributing factors such as the wind.
ReplyDeleteVery good job today. No one could have expected that these conditions were going to be so crazy. I hope you guys have better luck the next time you try to launch. On the plus side your blog is looking really nice, and I love the pictures that you are posting. Keep up the good work.
ReplyDeleteI am jealous you guys were able to make the time and i remember watching your guys rocket sail in the wind. I guess your guys parachute design did great. Leaning from the past designs really seemed to help each group especially you guys.
