The purpose of this part of the rocket project is to learn more about rocket motors and to figure out what makes motors good for the final phase of the rocket project, which is to build our own full rocket from scratch. Some concepts that we needed to learn/know include fuel types, what we want from a motor, and more.
Overall, the motor my group made was pretty successful. It didn't CATO, and had a reasonable
thrust (g). Nothing out of the ordinary happened, it was solid.
So the science behind the rocket motors we are messing with right now is that it uses a fuel(in this case sugar mix or black powder) and it uses that fuel to go through a combustion reaction. Depending on how you core it and the fuel, it'll burn faster/slower or more/less thrust.
Some questions that I thought of are ,"Should we use sugar or black powder?", "What core and what kind of burn type should it have?", and most importantly ,"What should we name our rocket!?"
In the end we decided on a half cored black powder motor, with 1/4 core 1/16" and the other 1/4 3/16". The nozzle was 3/16" but was later changed to 7/32". And we named it "Kim Jong Un Was Here", for comedic purposes.
For the real test, it did well. The motor did not CATO, and wasn't too weak either. The only flaw was that the burn time dragged on for longer than we wanted it to.
Looking at the data and thrust curve, I can see that it had a nice spike of power but it dragged on for too long. The spike numbers were great, perfect for launching a 200g rocket.
The total burnout time (t) and the total thrust in grams (T) values are on the raw data sheet.
From the compilation of motor thrust curves, the majority of our group voted that the Motor Abby and Carlos made was the overall best motor with Darien/Garrett and Mark/Erics motors tailing at a close second. The reasoning for these motors is because they were not weak, or overly strong, as well has having a overall great thrust curve. We are also assuming that the average rocket will be 200g, and we want a ratio of 5:1 Thrust:Grams.
For the rocket our group wants to build we are still unsure about it overall, however we do want to try to build a small rocket. We haven't come up with anymore details besides that.
