The modified bottle w/ laminated fins & (HUGE) cone
First attempt of the day
Today, was quite a challenge for my group members and I, though, luckily we (barely) made the required 5 second suspension time with 5.3 seconds. In the first diagram above, it depicts our first rocket of the day. As you can see for yourself, we only had four fins ~ attached by hot glue and duck tape. On top of our bottle is our parachute, which is covered by the lovely nose cone Taysia made out of recycled paper. Finally, we used a piece of a garbage bag to attach the nose cone to the body of the rocket (also one of today's requirements). In our first attempt (pictured above), the parachute did open, but it fell too quickly...giving our time at about 3~4 seconds. Unfortunately, the weather was not in favor with us today. The wind and rain may have been a factor in the poor performance of our second launch of the day (too embarrassing to show). Because our materials were not laminated in these series, the dampness of the nose cone and fins, may have had a significant role in the poorness of our second launch. But, we were able to make six new laminated fins, and a nice BIG nose cone before the period ended. In the end, the third launch was successful..but the parachute was tangled, limiting the time to 5.3 seconds, but for today, it'll have to do.
very cool pictures, especially the parachute one!
ReplyDeleteI like how you used recycled paper lols woo environment and it was interesting seeing your rocket evolve with the number of ins you had as well. Yea, the weather was pretty bad, but you guys are great problem solvers and although it only got you 5 seconds that's still awesome after your rocket being drenched in the rain.
