Ballistic Pneumatic Rocket (Programmable Payload Extreme)

thingiverse

Into the world of rocket science, until now the idea of payload inertia has been a relatively difficult & advanced topic to experiment with. From centering, balancing, and affixing extreme rocket payloads, to experimenting with different weights therein, there can be many theories on why a launched projectile "went that way." Designed to eliminate as many variables as possible, this update to our previous design allowed us add / remove weight to the extreme point of the projectile. By increasing / decreasing the infill for the design, we were able to observe the effects of different extreme-point payloads, in motion. Feel free to print with 0 infill, then add epoxy, BBs, liquids, glue, and / or other weightings, as well? Of course a different plan would be to simply provide nose cones of different weights & colors. (Updated: Did that on ***09/01/2019*** @ https://www.thingiverse.com/thing:3839776 .) In general however, I found that this approach allows several comparative launches to take place: Each print an exact clone in it's own right, this approach avoids much confusion by allowing us to end the debates that might ensue about nose-cone placement, centering, tampering (etc.) (I really need to pop in a micro-controller & and altimeter for the next iteration, but for now horizontal is easier to track, than vertical: Think "space derby"?) Your mileage might vary. Finally, allow me to note that I am no rocket scientist. I am an amateur rocket-man, simply looking for a better way to get things higher.... as well as a way to explain the much debated, ancient Grecian, long-jump record. p.s. This design is also different from the previous in that internal reinforcements have been added so as to allow testing at slightly higher pressures. The internal launch-tube wall-thickness has also been decreased, to a tad over 2mm. Be sure to read the warnings & launch safety ideas from the original print before rocket programming, printing, and use; use at your own risk. Enjoy the flights?
