2017年6月4日 · It is also important that the mixture is not generating smoke with the classic smell of caramelized sugar. If this is happening, it means that the temperature is near 180 °C, that is the point where the sugar decomposes, and this is not so good, because the powder loses part of its performance and can also auto-ignite:

2012年1月6日 · Sugar based rocket propellants have an average I sp (specific impulse) of between 115 and 130 seconds. Compare that to the average I sp of an APCP (Ammonium perchlorate composite propellant), which is 150 to 180 seconds.

2015年1月28日 · Decent rocket candy is definitely quicker to make. I would use a 70:30 ratio of KNO3 to sucrose for an end burner. Dissolve the KNO3 and sugar in hot water, and heat (not over flame!) until the water is gone.

2020年5月17日 · The model you mentioned looks like a good way to mount mini solid fuel rocket motors generally but Im sure the nozzle geometry for a sugar rocket must be tuned to the fuels specifications And so therefore I raise the question on how to create an efficient sugar rocket nozzle with a hardware store part, for my 3lb design I was considering using one, two, or …

2018年11月18日 · *At the Federal level, sugar rocket fuel is not within the specific outline of low explosives but should be considered 'Black Powder' for the sake of remaining unaccosted by federal officials. It IS mentioned in the NFPA 1122 and almost all states have adopted the 1122 in their fire code, this means that at the state level, all the rules in the ...

2021年1月8日 · IMHO, the best way to make Rcandy is to use regular sugar and dissolve the properly weighed out mixture in a small amount of hot water and then boil it down. I use an electric hot plate with a thermostat and an old pot. The idea is to boil out all of the water, but not carmelize the sugar as that will reduce the performance of your rocket.

2018年9月27日 · The sweet spot for a BP rocket is usually found by experiment, too small a nozzle and it goes bang, too large and it doesn't make thrust. Try bore/3 as a start. Research other threads about sugar rockets for information, or find and join a rocketry club -or both.

2012年1月7日 · It's such a simple rocket. If you can make a sugar core burner you can make one of these. The only difference is a slightly smaller nozzle and BP rammed inside the core. I need to get some new videos up, but all I do lately are night launches... Ugh, it's such a pain in the neck to hand ram a 7.5" x 1-1/4" ID sugar rocket... BP compacts so much ...

2010年11月26日 · I'd also look at using an engine slightly smaller diameter than the body of the rocket and using stand-offs, etc. The engine would probley be made out out several grains, think like cored grains 6" each in length. You could start making 6" grains of whatever diameter and I guess keep adding them to a longer and longer engine as you figure out ...

2011年3月27日 · my first rocket was a 40mm with a whopping 250g of fuel sugar rocket with six short bates grains spaced 10mm apart and cored 10mm steel nozzle and plaster plugs. needless to say i was oblivious to my new very high powered rockets potential destructive ability, [i followed the tutorial so its ok, WRONG]the thought alone scares me and since i ...
