After 3D printing the launchpad, the rockets were ready to be launched I felt optimistic before going out to launch the rockets, but my...

Having a total of 6 rockets, a total of 18 fins were needed since each rocket would have 3 fins. The dimensions for each fin were as...

The fuel container was connected to the cardboard body of the rocket using hot glue. The container was connected such that there was 12cm...

After the hot glue was cooled, the PVC pipe was attached to the link, which was previously 3D printed (https://mjkim22.wixsite.com/rocket...

After building the body of the rockets (https://mjkim22.wixsite.com/rocketlab/post/cone-shape-experiment-5), I realized that using molten...

After testing with the fuel, I moved on to building the body of the rocket. The rocket body was prepared by cutting a 70cm cardboard pipe...

The first attempt at making the fuel for the rockets that are to be used for the cone shape experiment was done as shown below: These are...

It took about two and a half weeks to print and detach the rafts of all 10 3D printed cones (4 smaller cones + 3 bases + 3 tips of bigger...

With the STL files download from Fusion 360, and after converting the STL files to gcode with FlashPrint, I am finally ready to print the...

During next summer break, I have decided to conduct an experiment to investigate the effect of rocket cone shape on its total vertical...

After the three parts: the main body, the inner gimbal, and the outer gimbal were 3D printed, I assembled the three together...

The next file that I will 3D print is the outer gimbal. This is where the thrust component perpendicular to the inner gimbal is...

With all STL files converted to gcode, I can now print out the necessary parts for the TVC mount. The first two files I will print will...

The finished design of the TVC Mount using Fusion 360 looks like this: (View the full screen recording video of the designing process...

A TVC Mount is a device that allows rockets to be stabilized during its ascent, since there are many factors (such as drag and unbalanced...

After observing that the fuel mixture works brilliantly, myself and the team waited for about 10 minutes for the fuel to cool down. Then,...

The most exciting part of rocket fuel making is here. After mixing the fuel (sugar) and the oxidizing agent (potassium nitrate)...

With 500g of fuel (sucrose) prepared, I first transferred the 500g of sugar into the frying pan. Then, after I ignited the butane gas...

A typical sugar propellant mixture is prepared in a 13:7 oxidizer (potassium nitrate, KNO₃) to fuel (sucrose, C₁₂H₂₂O₁₁) ratio (by mass)....

These are the equipments that I myself bought during the holidays and brought to school. They include a butane gas burner, butane gas...

The photo below is the finished actual structure of the rocket module of Mk.1, composed of the cone, a 0.75m PVC pipe, and three sets of...

Next, I moved on to printing out the cone again. The cone was relatively easy to print out because it was smaller and so took less time...

After the three identical leftover parts a printed, these are the 6 pieces that needs to be assembled together: Firstly, before they are...
