Easy Rocket Motor Igniters - Great for Sugar Motors

Supplies:

Aluminum, magnesium, or magnalium powder is a good choice. The finer the better, as they quickly produce very high temperatures. Well done.

Nice, I use a similar concept with the wire, but with my ignition mixture is dissolve a ping pong ball in acetone to form a paste and then add the rocket fuel powder to it. Really enjoy the videos.

VERY cool ! always wondered how to do this. Used to play with Estes rockets as a kid and wondered how it worked. Thanks Man!!

[isekaiexpress]

Now that's more like it, thank you! I will use it for my harmless rocket hobby. To the moon!

Every time he says 'propellant', drink.

Dollar store light bulb. The filament cut into pieces. Burns white hot with a 9 volt battery.
If longer burn add a tiny bit of green fuse.

Been using cat5 nichrome wrapped igniters for years with my diy bp with aluminum powder. Instead of soldering I use my trusty radio shack wire wrap tool.

Made some using this formula and steps!! Works perfectly!!! Thanks

It's like making fly fishing lures

Could you show us how to cast and make amonium perchlorate, aliuminium and ruber binder fuel? Also would you mind explaining what the ruber binder is for

[pirobotbeta]

Silicon powder, potassium perchlorate, trace of sulfur, some kind of binder.
Silicon burns, becomes shower of molten glass bits.
Glass is quite sticky when white hot, clings to fuel grain, ignition rarely fails.

I use a 120 volt 30 amp solid core 10 gauge copper wire to lite my rockets up.

Instead of keeping these igniters in a carefully controlled (jar with desiccant) environment, I'd try sealing the sugar based coating from the humidity by painting/dipping them in a flammable lacquer, like fingernail polish, or the glue used for PVC piping. That way they could be stored without concern for the hydroscopic nature of the original coating.

Hello...Greetings Minute Rockets. I just wanna ask a question that, I am trying to make a blackpowder igniter for my rocket motor with BATES-neutral burning grain with a Maximum operating pressure of 934psi (targeted).Do I have to use the amount of BP such that the pressure generated by the hot combustion gases of the BP will be in range of max operating pressure of the motor (For Startup phase) ?

Steel safety wire also works like your nichrome wire did, for cheaper, if you are using a good power supply (ie: motorcycle batery).

[miken]

U could use a 10 ohm 1/4 watt resistor instead of nichrome wire

Does it really work better than an ematch ? The motor test doesn't seem to start faster than when I use ebay ematchs. Nice method overall but it might be actually worth it if a proper pyrogen is used. Unfortunately, those are somewhat difficult to make, particularly in EU

I use bead stringing wire it starts on fire - has tin in wire

[lutheruchiha]

great job bro! just a question: 9V or 12 you use to fire your igniters? Thx... and continue!!! ;)

Beeing trying to use potasium nitrate and sugar mixed together with a very smal quantity of water. Mi mixure did not work. How much time would you expect it takes for the mixture to be fully dry and usable if any?
