In this project I researched the two different kind of rockets, an end burner and a core rocket motor. The difference between the two is in theory cored creates more thrust because more fuel is being burned at one time. End burner's are very constant and reliable, they typically have a longer burn time than the cored rocket but sacrifice a lot of thrust which is fine for a smaller rocket. Then it was time to look at sugar rockets and black powder rockets. I chose a sugar rocket because I wanted to test something different and fully cored it. The black powder had a lot of benefits such as burn time but I wanted to try this out. Sugar rockets also seem like they don't have the chance to produce as much thrust as a black powder but Garrett and I wanted it to be for a smaller rocket.
We finally gave Andrew our design and I was wondering whether our sugar rocket would blow up or not. I waited over the weekend and we heard bad news of tests gone bad conducted by Andrew which wasn't good considering he tested sugar rockets.
Then the moment came when it was time to test the motor, we went out to the field and tested my motor and when I pressed the button to start it it screeched loudly. I thought it was going to explode but luckily it didn't and I felt a sense of relief. As you can see in the video it started off really strong and then just stayed alive for the rest of the time.
We made a thrust curve in class for others to see how ours worked and I was thoroughly satisfied by our rocket's performance. A motor's thrust curve effects a rocket's performance because it shows how the rocket motor behaves and you can determine what kind of rocket it was. It had a total thrust of 14128g and a burn time of 7.4. Our motor was interesting because it got towards the end and didn't stop burning for some reason. It seems like a good design for a small or medium rocket because of its thrust time and overall thrust. In the end we liked Alex Wessel's groups rocket motor because Garrett and I wanted to make a smaller rocket and his didn't have too much thrust and an alright thrust time. The graph above is my sugar rocket and it surprised me with its performance and for this I am happy. Looking at this project I was very happy with the final product and enjoyed the project overall. I gained teamwork skills and got to understand rockets more in this project.
