@KaMakeLoa I know this video is quite old, but question:
I've been building about 30 small (1/4 pound) rockets now using dry KNO3& Sugar, the best one went about 300 feet high. I want to upscale my rockets now, do I have to use molten mixture now? I've made an aluminium rocket case, 2" diameter, about 10" long. Nozzle is stainless steel fitted with 3 small bolts.

so umm ya totally had to pick up my lower jaw from the floor after that
-
that was awesome
-
sir where can we get that software?
-
how do you position the grains in the tube? are they just long cylinder shaped things mounted side by side in the tube? how long was your pipe? Very nice rocket! how high did it go?
-
I would love to see how you built this.
-
how big do you think the nozzel should be for a 1.5 inch pipe?? thanks
-
Yup.. 1" dia core..

Big sugar rocket motor O-11Kby fffori1,301 views
Wow, that was a powerful motor. You say it had two grains, 3.5''wide by 6'' long, with 1 inch core in them. Was the nozzle 1'' as well?
So, your Kn would peak at 114, give you 250lbs of maximum thrust and a pressure of 231 psi.....was that the calculation for you?
And yeah, it is L motor--1047...yeah and the burn time was a good 3 seconds+.

Those were the approximate specs we calculated using a program from CP Technologies & actual thrust stand data prior to launch. Another launch is planned for later this year using an high M / low N class sugar motor.
I'll post ground as well as on board flight vid's as soon as available!
Thanx, Rick.
