Now that this project, I feel kind of sad that its over, I had a really really fun time during this project, Making rockets and seeing if they work. This is so far the best project ive ever done, I am glad I finished this project with a really good end, MY rocket flew perfectly fine it went really high and came dow really good, but the parachute didn't eject, it caught fire in the rocket but it burned out really fast. if the rocket launch was bad and it just blew up from the beggingin I would of been sad and begged to do the launch over again. but we ended the project really good and it weas really fun. This was my first time actually making a rocket and launching it . it was a really good and fun expeierence. One thing I was really amazined by was how we can basically make a rocket motor out of anything. Like some of my class amtes made a rocket motor out of sugar! who knew you can make a rocket motor out of sugar!?!? One of the technological things I learned is the placement of the fins on the rocket. Theres math behind it! I thought we just put the fins on and were good, like put them on the end but in reality we had to measure the fins perfectly asnd then find the center of gravity of the rocket and then measure the circumference of the rovket tube and then do something asnd something elser and BAM you found the correct plae the fins should go! I bet that sounds confusing, Same here. During this project I learned that I liked to do the most work just to make sure its finished by the time we need it done, I learned that I liked stuff to be unique not boring like plain or something like I made a Incredibles logo just to purt it on the rocket. I also learned that I liked to take control but I let all take control too. I worked with Kailee and Handy for almost all the projects we did in Chemistry, and I believe we all work good together stuff actually gets donne and we still have fun and talk, I really like the little group we have, I feel like we each did the equal work in every project we had. If I can do this project again I would try to make the rocket lighter, Like take out the parachute and make the bdy out of something really light and make it a bit shorter or even put 2 motors in it. I would use the same motor and fins, The advice I have is to get it done, don't hang around and wait till the last day.
Well, this year was AMAZING! I've done tons of experiments with Andrew and my table group, They were all really fun and some of them I have no clue what they were going tot come out like in the end. I learned that I like learning off of people showing me what to do and taking to me, instead of telling me how to do it. For example my first time changing out brake pads on a car my brother showed me how and then I did the rest of them my self and he just watched me do it. I really liked the rocket project a lot, I never made a rocket before and actually launched it like how we did, It was a amazing experience.
After this project was done i was really happy because the rocket launch was really good, we had a succesful launch on the last day of the project. If it it didnt launch i would probably be depressed right now. This whole semester was really fun with Andrew, I learned tons and tons of stuff i never knew about, we also did some expirements in class,
Well Kailee, Handy and I wanted this rocket to weigh at most twenty grams ALL TOGTHER but we found out that was impossible with the rocket tube and the fins and the motor. For the "rocket tube" we used a three slim pieces of paper, they were about two feet long in length and about four to five inches in width, we had a piece of PVC pipe and we rapped up the PVC pipe with the pieces of paper; the first piece of paper we slowly wrapped it around the pipe and taped the edges to the end and then the second piece of paper we covered it in wood glue and also wrapped I around the pipe but we wrapped it the opposite way the first one was and the third once we did the same but just the opposite way the second one was so like the first one. Then we made our motor, It is the same motor I talked about before in my other blog post, it is 66%, 33%, and 1% Iron oxide. Kailee and Handy (footy) wanted the rocket to be a light blue but I wanted it to be red, so they didn't tell me and started painting the body blue, I got mad and went outside and when I came back I took the fins for the rocket and started painting them red. We made the parachute out of some type of Hazard bag thing it was supposed to be not flammable but it caught fire in our rocket so it lied to us. Looking Back:
The experiment turned out really good, The goggles have really good focus, the vision is really clear, no blur at all. But the out side of the goggles look really really bad, I put a lot of duct tape everywhere on the goggles just to hold it in place, at the end it is still really flimsy but hey the vision is really clean, thats all that matters. I could of used a lot of less duct tape to get the same result but oh well. Looking Beyond: During the process i had tons and tons of questions, a lot of my friends were finishing their goggles really really fast and we were barely printing out the template and i was scared that we weren't going to finish in time, we had to restart like 3 times because we messed up on one major part of we duct taped it all together and forgot to make a hole for the phone to go in. Looking inward: Yes i think i did good, I took me like 6 times to get the lens and the phone in a perfect place to get a really good vision. Looking outward: For the VR Goggles i worked with Handy and Kailee again, because were awesome. Over all i think my grouped preformed well, we didnt really try to get this finished ASAP but when we needed to get this done we really worked on it, all of us cut out the pieces together so none of us did more work than others, i think i tried to be in charge a lot so i tried to do everything. We each cut out some pieces, we each taped them together, we all held the phone and the lens in different places to get really good vision. Looking Forward: One main thing i would change is to take my time on taping it together we taped it together really fast and i believe thats why it was so flimsy at the end. For this I'm in a group with Kailee and Handy, We were watching different video's on YouTube about motors and then we found one that was called Rocket Candy(66% PotassiumN Nitrate, 34% Sorbitol and 1% Iron Oxide) it is red and very very sticky, it is not at powerful as the other motors. I believe most of the other motors got 1200+ thrust and we only got 600 Thrust but our burn time was a little over twice their burn time. Our estimated peak altitude is about 730 feet in the air but to achieve that number we will need to make the rocket out of balsa wood which is very light, but if it doesn't come down nice it will most likely be in a thousand pieces when it hits the floor.
LOOKING BACK: WHAT HAPPEN? Well we tested our motor about 10 times, At the beginning it was very very bad, It was only about 300 thrust, then we made 3 more motors, tried different stuff each time at first we started off with a end burner but then we switched to a full core which worked a lot better but then we tested it out and the thrust was barely around 450g. We wanted more thrust so we decided to make the core smaller so the final core was 3/16 which is really small, so small it has a chance at exploding almost everytime, thank god that never happen to us. LOOKING BEYOND: Well the first time I seen this motor on youtube it looked really cool to me, I think I liked it so much because it produced a lot of smoke but then on the video the person was putting it in was a over sized Lego and I was wonder if it had a lot of thrust or if it was even going to lift the rocket in the air? LOOKING INWARD: I think as a group we did really good, because we each had to do a lot of stuff for this motor, we constantly talked to JP and Andrew about our motor, so that was a lot of running back and forward of just trying to get this motor where it at right now, Not a one part of the class were we sitting down, we were always trying new stuff on this motor, like other groups only tried their motor like 3 times, we did it 10 TIMES! LOOKING OUTWARD: I worked with Kailee and Handy( Mano) like I said before we r=did really really good as a group for this part of the project, we all worked equally, most of the time I cleaned the drill bits but yeah we worked good all together. LOOKING FORWARD: Well the only thing I would change to get better results is try to put more iron oxide in the motor. I think that will help a lot but the motor will 99% explode. Other than do that I wouldn't change nothing at all, Everything went perfectly fine for this part of the rocket/project. For the next experiment in this class I will try to stay in the same group because I feel like I work better and they help me a lot on staying on topic and actually working inn class instead of fooling around and or leaving the class all the time and not doing any work at all. Rocket Body Radius (m) = 0.02 Rocket Body Cross sectional area (m) = 0.001256637061 Fill in the boxes below to have a peak altitude for your rocket be calculated. Motor Average Thrust(N) = 3.2 this is determined from the thrust curve data Rocket Mass(kg) = 0.015 this is a variable, depending on how massive you want your rocket to be 1000 Rocket Body Cross Sectional Area(m^2) = 0.0013 A = πr^2; again depending on how big you want your rocket to be 9.803921569 Burntime(s) = 3.5 determined from the thrust curve also Motor Mass (kg) = 0.08 These values are assumed Motor Dry Mass (kg) = 0.055 The dry mass is a motor without fuel Rocket Peak Altitude Prediction = 215.4176492 meters 706.7508401 feet This was our very first launch with our rocket, i think it did very good for our first launch We started off with a couple grams of sodium polyacrylate and some water, The grams of SP was in a cup and then we poured in water slowly and mixed it and it started turning in the a ice like material. It kind of looked like a slushy to me. Our task was to find out how much water can this really suck up or hold. We kept add more and more water then finally it was almost gone. So then we got another cup of more SP and we added milk to it and nothing at all happen, the SP didnt suck up any of the milk at all, it just sunk to the bottom. We then put the SP with the water in a glass pan and then added food coloring wich made it blue. Class was almost over and then i added milk into the pan as you can see on the last picture.
