New way to make cheap, simple rocket nozzles.
Hi all, I'm new to this community, so if I'm breaking any rules, please let me know.
This is from a static fire I did almost two years ago now to develop a solid rocket motor using nothing but hardware store components (except for propellant). This was only my second time making propellant, so the grain was pretty terrible. However, from what I could find, I invented a new way to make cheap and effective rocket nozzles. I used washers to make the throat, and JB Weld putty with a 3D-printed mould to form the converging and diverging sections. All of this was built into a PVC pipe coupling, which was then attached to the PVC pipe casing. Here is a link to a more detailed breakdown. The benefits of this technique is that it does not require any special tools, only a 3d printer.
From what I have seen, no one else has used a technique like this. If this is not the case, however, please let me know.
