Looking Back: What happened? Phillippe and I were finally able to launch our rocket, with fantastic success. Because many of our rocket motors exploded on ignition, we needed to use an E-Match, an electric match that at the press of a button flares up to light anything combustable next to it. Our rocket hit a "high" of around 2900g of thrust! This means our rocket body we build can be much bigger than most, because of the thrust at launch is enough to get a bigger rocket in the air.. Looking Beyond: What do you think has happened? What’s the science? From what I can tell, the science behind our rocket launches would be combustion, pressure, and thrust. First, the E-match lights the end of either an end burner or core burner, and the combustable material lights up and starts to create great pressure. As it burns, because the energy has no where to go, it exits the end of the motor giving it energy to fly in the opposite direction of the energy release if it is able to (without a scale in the way). Looking outward: Collaboration and Impact I think my partner and I did really well coming up with a rough draft and getting our rocket labeled with the right statistics for fuel and core details. One thing I would improve on would have been to ask more details of how each motor is made, as we are not old enough to create our own. Looking Forward: What next? The next time we come to Andrew's for chemistry, it will be to build our final rocket body and motor from scratch, combining each of the rocket sections into one launch. Take aways: What I took away from this motor launch is the seriousness of safety when it comes to motors of this size. At first, I didn't think much of them. But when I saw the power of them exploding my opinion changed. It makes sense why they have so much power, because of the amount of fuel to surface area we added. These motors should not be used lightly. Thrust Curve: Interpretation + Choosing a Motor:
I liked our thrust curve a lot. We have plenty of power and for a fair amount of time. At first, because our motor was cored, Andrew and the rest of us were thinking it would explode. However we were pleasantly surprised, as our rocket gave out the most thrust in the whole class, allowing our rocket body build to be full of possibilities and have less limits compared to another rocket with half the thrust. We want to choose our motor because our thrust curve looked the best to Phillippe and I.
