Hi,comrades rocket modelers,lately I'm poffered to myself a series of questions in regard the rocket motor, in particular:
-The nozzles's diameter
For the nozzle I use the chalk compressed and with the drill I do only a dimple,I am feared at the think who too small will make an explosion (I can say who the my rocket have a problem of center of gravity who will be resolved soon but have an weight of about 1/1,50 pound who can help me on this problem?
About the propellant:
I use 35% C12H22O11 (sucrose) 65% KNO3
I need to know only if can work without fuse the mix,if can use an catalyzer (34% C12H22O11 (sucrose) 65% Kno3 1% Fe2O3 or something else) or I can use the KMNO4 instead the KNO3...I know the dangers of the KMNO4...If someone need the combustion chamber's dimensions I will say to him after: Because?
Firstly: I've worked all the day on those problems,so in this precise moment (21:33) I am falling for the sleep
Secondly: I need to measure them accurately,scilicet I need time and work without a s****y ruler.
Thanks in anticipation ^.^
