Launch Day 3
Today we launched our water bottle rocket with different modifications. Today a parachute was required and a 3 sec flight time was required also. Our second launch that we did was a complete failure because of the type of material that we used to make our wings so today instead of a heavy piece of wood we found a very light wood. We cut 8 small wings about the same size and covered them in duck tape after (preventing the wood to soak water making the wood heavier). After hot glueing the wings on we needed to put a parachute on. With the time limit given we just got a plastic bag and taped the plastic bag to the top of our bottle. As we launched our rocket seemed to be perfect, our flight time exceeded the time limit of the requirement given to us today (flight time 18 secs) and our parachute opened will in the air. What we will next strategize is how to create a better parachute so our flight time would be even longer and maybe make some adjustments to the wings. We may also fix and find a better nose cone besides the top of another water bottle so our launch could be better. We were very happy today knowing that our parachute opened and our rocket worked perfectly.

Congratulations on the long flight time. What is the secret to deploying your parachute? I'm having a lot of trouble with it. Also how did you get the rocket to stay in the air for 18 seconds?
ReplyDeleteWell we basically used a plastic bag and taped four corners of the bag on to our rocket then put the nose cone on top. We didnʻt believe our parachute would work as well as it did but simply taping it on did the trick. As for the 18 seconds, our rocket flew perfectly straight thanks to the eight fins we attached. Also i think we could have had our rocket in the air even longer if our parachute had deployed earlier.
ReplyDeleteNice rocket lauch, one day i hope to be a boss like you. Also did you guys add any extra weight to your guys rocket?
ReplyDeleteI canʻt believe you guys got your rocket to stay in the air for 18 seconds. That's insane! Was your parachute located underneath of the cone? or was it exposed on the top of your rocket? and do you think the use of 8 fins made your rocket more stable?
ReplyDeleteYeah max try using smaller fins, but add more than four. If you can try putting four big fins and the other smaller fins in between for the best stability.
