Today Sophie and I were finally able to create a rocket motor. We ended up doing a layered motor with 20% black powder fuel and 80% sugar and potassium nitrate mixed fuel. The black powder was half bamboo charcoal and half balsa charcoal. We used a 7/32" core to try and get an even higher maximum thrust for the motor. During our process, Andrew helped guide Sophie and I on what to do when making motors. By third period, we were finished and able to test how well our motor would work. We put it on a thrust stand to measure out the maximum thrust. We then lit the motor, which blew up immediately. One of the reasons we thought it didn't work was because the 7/32" motor created too much pressure inside of the motor, causing to to release the pressure by blowing up. Afterwards, we found a piece of compacted sugar and potassium nitrate fuel from inside of the motor. We decided to do a quick burn test to make sure that it wasn't also the fuel that contributed to the blowing up. When we did the burn test, the fuel burned exactly like it was supposed to, which means that it wasn't the fuel. That also meant that next time we need to use a 1/4" core instead. It was good to hear that our motor idea can be really successful if we just adjust the size of the core. Both Sophie and I thought it was really cool that our motor might actually work well. Hopefully next week we can make another motor with a core of 1/4" instead this time, which if it works, we can verify and make our final motor. Overall, our experience of making a motor was still successful even though the motor didn't work as well as we were hoping.
