Hybrid Rocket Engine Test 1

[silver760]

Please tell me you have a flashback arrestor between your regulator and engine? I also wanted to know if you are aware of the reaction between gaseous oxygen and oil/grease? These two combined can spontaneously and violently ignite.Classic examples are where oil/grease contamination is present without the user being aware of it on things such as fittings,tools,seals,sealing o-rings etc,just to let you know.I don't know what %O you are using or it's pressure but better to be cautious.

[EpicFailureProducers]

also, I've built this exact same thing... i really want to try it but i cant find an oxygen tank. All i can find is the oxygen at ace hardware that comes in a bottle(without a valve)

[EpicFailureProducers]

What is the size of your fuel line wire?

[Maxequalbikermadness]

nice little project you've got goin there.

[gunshow589]

idk how reliabal of a rocket it would be bc of the leakage and the poping but still a very good motor

[pangpengmaster]

freaking awesome! Have you ever try nitrous oxide as oxidizer or hydrogen as its fuel?

[jrbpyro101]

@pangpengmaster I haven't tried nitrous yet, its actually almost impossible to find here. If I go for hydrogen Im going to use liquid hydrogen in a liquid engine.

[pangpengmaster]

@jrbpyro101 You can probably get N2O as an anesthetic or just simply obtain it from heating Ammonium Nitrate or mixing nitric acid with sulphamic acid. I did it at home but I never thought to make a rocket engine. But its dangerous too, so Oxygen is still a better choice. BTW, I'm subscribing!

[orchidjessica]

@jrbpyro101 were would you get liquid hydrogen?

[jadejordan1]

marshmellows?

[1943vermork]

so cool, thanks for posting

[tomekkk10000]

Oh man, you don't get on moon with this rocket :]

[brandonsg123]

OMFG I LOVE U!!! THIS IS EXACTLY WHUT IVE BEEN SERCHING FOR IS THER A VID TO SHOW ME HOW TO MAKE THIS?!?!

...ther is a reason to this....im goin to make 4 of these and strap two to each of my feet....dumb u say? no....if it provide lift ill fly several feet but the thing is.....i have dreams bro teach me how to make this and u wont crush them thanks  =P!!!

[kounga999]

Lightsaber prototype...

[fear4maplesea]

you should like try to touch the orange molten stuff, and you'll end up on RWJ. LOL JKJK don't touch it. Suck on it LOL

[brandonsg123]

@fear4maplesea whuts RWJ?  =P

[Willlarkbe]

@brandonsg123 RWJ is an acronym for Ray William Johnson, the host of a popular show by the name of =3. Look it up.

[killaaa2106]

if u release the wrench will it fly?

[jrbpyro101]

@killaaa2106 I'm not sure of the thrust, so I don't have a definite answer.

[chieftech100]

hardcore

[TheAnatomias2]

you sound young so bravo for experimenting...take a look at convergent-divergent nozzle design(de laval nozzle) for effective thrust (Mach>1 exhausts)...be careful though with oxygen...try experimenting with solid fuel first,familiarise and optimise those designs and then go into hybrid...keep it up!!

[t0xIc177]

you are 1 step closer to make a lightsaber O.o

[milkeboy22]

sick

[boatoflol]

So basically you burn a piece of polyethylene tubing inside of some metal tubes with a continuous stream of oxygen. -.- hm looks good, but thats all.

[KLpyro]

I want a dad that would do such things with me :(

My dad only thinks it dangerous, although he played with it in his youth too :,(

Does anyone has any advice on convincing your dad to do this?

xD

[jessiebm123]

how do you put it on a small scale rocket ??? the oxy tank cant go with it lol

[jrbpyro101]

@jessiebm123 Well Ive never personally measured the thrust, but if it puts out 10+ pounds of thrust you could easily make a lightweight tank to go with it.

[patton1500]

But will it blend?

[nakazatoGTR]

advice from sugar rocket maker: reinforce/replace nozzle with either concrete.

i used concrete for nozzles for my sugar rockets

[BamMcGra]

Verry Nice Design, Quite Amazing!

It Looks Sort Of Like A welder or light saber.

Ever Tried Cutting/Welding Metal with it?

[Blitzerjunge]

amazig



[MontyProductionsInc]

It's called a Mach Diamond

[Helicopterpilot16]

haha I saw a shock diamond!

[Mr41432]

@Helicopterpilot16 what's a shock diamond?

[Helicopterpilot16]

@Mr41432 a form of shock wave that you can see behind any gas powered jet or rocket engine when the exhaust passes the speed of sound, look on google images!

[cookiesrock35]

thats the hottest type of flame you can get right there (white)

[smokescreenninjato]

@cookiesrock35 actualy the hottest type is a blue/ purple flame because blue has a shorter wave lenth than white which is just a collection of all the colors.

[cookiesrock35]

@smokescreenninjato yeah i knew it had to be on or the other but my old science teacher said white O.o lol

[boolykbol]

To prevent overheating,you must have a cooling water,jrbpyro101.

[nachojr456]

hahaha! the flames are coming out the sides!

[pkrollp]

dont do this! pure o2 can explode if the flame runs back into the take look at Apollo 11

[jrbpyro101]

Pure oxygen can not explode! Its an oxidizer not a fuel. Apollo 11 never had a fire or exploded, that was the first maned mission to land on the moon. Apollo 1 is the one that caught on fire because they were in a pure oxygen environment and it made all the velcro and plastic and such more flammable because O2 an oxidizer, and a spark ignited them, all the plastic is what burned not the oxygen. Oxygen doesnt burn by itself.

[aCagedApe]

Hey send it off into the air now.

[jrbpyro101]

I will do a video how how it was made today. check back today or tomarrow

[jrbpyro101]

just some brass fittings and tube inside. Ill do a how to soon So check back!!
