MinamotoKobayashi Posted July 9, 2018 Posted July 9, 2018 (edited) Hi forum, I'm back. This time no tutorials but pretty soon I will create, step by step, how to make nice fireworks with r-candy rockets. I have refined some personal procedures using r-candy rockets with traditional shells, so stay tuned. Here is some nice launches: An incredible fast 500 grams r-candy nozzleless rocket: https://www.youtube.com/watch?v=aCp2VyHSCR0 R-candy nozzleless rocket only for 4" shells: https://www.youtube.com/watch?v=fqmPDppS0wU "Little dick" nozzleless short rocket with 20 mesh granulated r-candy compound plus fine titanium pressed at 1 ton with 2" shell containing KP and titanium: https://www.youtube.com/watch?v=Qgn9Q-jMkxs 4 inch golden glitters powered with a PET-NOZZLE rocket: https://www.youtube.com/watch?v=CwV9Q0MAI2Y 4 inch willow diadem extra: https://www.youtube.com/watch?v=YcSuuf40jjo 4 inch red and green: https://www.youtube.com/watch?v=X6ti_6s0woQ 4 inch strobe: https://www.youtube.com/watch?time_continue=1&v=s851Kz5ief4 A very dangerous CATO of a 4" shell: https://www.youtube.com/watch?v=nAmm7ztGo-0 A rocket departure in slow-motion: https://www.youtube.com/watch?v=_QoFo08RBj0 Edited July 9, 2018 by MinamotoKobayashi 2
Sulphurstan Posted July 9, 2018 Posted July 9, 2018 (edited) Minamoto.Did you investigate the 4'' Cato? How did it happen? What was the design of the motor?How it could happen just around 1 sec after takeoff? It could be interesting for other Rocket builder! Edited July 9, 2018 by Sulphurstan
Sulphurstan Posted July 9, 2018 Posted July 9, 2018 (edited) But still: all other rockets are cool: nice ascending tail and symetrical spherical breaks 👍 Edited July 9, 2018 by Sulphurstan
MinamotoKobayashi Posted July 9, 2018 Author Posted July 9, 2018 Hello.The CATO rocket was made with a PET nozzle motor.This model cannot manage even a little spike of internal pressure (due for example to propellant imperfections such as air bubbles),so I switched to the most stable and performant nozzleless motors.If You search around the forum my other threads You can found also the PET nozzle motors project.
mabuse00 Posted July 17, 2018 Posted July 17, 2018 Nice stuff Kobayashi Which calibre are your rockets?How long are your spindles and how do you process the candy?You mention pressing...?
