sugar syrup propellant static sest

A static test if sugar syrup propellant in a 1 1/4 inch pvc motor with a steel nozzle. The video is from jamesyawn.com It sucks not having a good camera. My static tests very very similar if not the same but I didn't get them on tape. It maxed out the force gauge. Sugar syrup appears to have potential. It's easier to make than recrystalized and the propellant is almost as good. It can be made very quickly and can also be made in the field on a camp stove. A big plus.

so is this an end burner rocket or core burner ? sorry i got no idea about R candy rockets, I dont know if i need to make a drill into the hard candy inside the tube.

Rcandy is usually used in a core burning configuration. what you do is press a coring rod through the case while the propellant is still hot and pliable and keep twisting it unitl the propellant is cooled and hardened. I would n ot advise using a drill as it is possible that the friction from the drill bit could ignight the propellant.

Oh ya.. what do u mean sch 40 ? would you tell me what is the thickness in (mm) ?

[airgunsniper]

The wall thickness varies with the diameter of the pipe. It is the thick walled high pressure pvc pipe.

hows it going i live in new zealand and learnt rcandy motors from james yawn as well he is a very helpful man ive built his small motor and built a couple of bigger now to ive uploaded a couple from last year but well past that now gana try to get new cable for camera cause the biger one put out over 90 pound still going straight at 450meters jimmys a legend

lol you mean Sakrete ?

Me ?....The Home Depot Clerk

i tried a 1.5 inch rocket build..

true pouring inside a 6-inch is a pain, so i made segmented moulds. of course with core burn are(hole though out length) then stacked them inside tube.

nozzle = PVC end cover with 9mm hole filled with concrete with 7mm hole.

igniter= tel wire wound round 2 match heads inside the covered end..

result?

thrust=.9 kg,

Burntime=30secs....

heheheeh.

what do those hrdware clerks call that iron oxide based concrete dye?

man that is powerful - how did you make it

[TheUnforgivn17]

So do you use pvc sch 40 for your rockets and if you do what size? 1/2"? I used sch "a" once on accident i cant believe i didnt think of it and i did a bp burn test and it cato on me. I was thinking about sch 80 but that might be overkill

[davef21370]

use a drill, kno3/sucrose ignites at over 600C, you'll be hard pressed to generate that heat from drilling it, i do it regularly with no problems and also machine my propellant grains on a lathe at fairly high speeds.

it's safe.

[trekridr42]

where did you get that nozzle i have been looking everywhere for one

[airgunsniper]

Generally, Rcandy requires a core burning configuration to burn fast enough to produce thrust. Really there is no way around handling it. When it is cooled slightly, but still pliable, then press it into the casing and then push your coring rod all the way through the propellant grain.
