Rocket technology is a tricky thing, but as long as you don’t want to go into space, the whole idea basically boils down to a simple concept: anything can fly if you put enough thrust behind it. At least for a while. It is this basic premise that enables amateurs sometimes call it “strange roc” to fly; These unusual objects may not be ideal rockets, but if you put a large enough engine in it, it will leave the launch pad.
Recently, [concretedog] thought he would try to assemble his own eccentric rocket and set about refitting the Doritos stark tube for power flight. There are many precedents for turning the Pringles tube into a rocket, but of course, this is not surprising. After all, what is a rocket if it is not a solid and light cylinder? However, the circular triangle of Stax tube is expected to become an interesting rhythm change. Plus it looks cool, that’s it.
It’s easy to turn snack containers into rockets. First, [concretedog] drew a circle of the outside of the pipe on a piece of paper, and then took a picture with his mobile phone. Then, the image is introduced into Inkscape and transformed into vector file, which can be processed at will in CAD.
Between his laser cut thin plywood and the PETG loaded into the 3D printer, he was able to design a strong enough motor support to carry Estes d12-5. Then he created some fins glued to one side, and a triangular nose cone. A simple recycling system was installed, and the whole process ended with orange and black schemes suitable for Doritos.
The unusual shape of the rocket means that it cannot work to simulate its flight characteristics on the computer without customized software, so [concretelog] has to use the old-fashioned method to check the stability by winding around the rope. After trimming it so that it could be positioned correctly on the tether, he was quite sure that it could fly in a straight line under power. Sure enough, the following video shows the Nacho cheese flavored rocket flying into the sky with amazing speed and stability.
This is far from the most advanced rocket model we have seen recently, but we really appreciate the simplicity of construction. This is a good reminder that fun is not necessarily high-tech. by following some basic construction principles, you can destroy a safe Park flying rocket at the weekend.
