Propane and compressed air?! Dude that is awesome. I should have known you could get those kind of results with air only oxidation and enough input pressure but I just never considered it.
Wow, I was just saying he should test that Starlite from your channel, and I didn't even notice you were right under my comment haha!
@@3000gtwelder It would punch through starlite I'm sure, not because of the heat but because of the pressure blowing the carbon away
I’d like to see u take a crack at making a rocket engine
@@tannerwatson1216 i expect that would wind up much less hazardous too
Well he was starting with 49 horse power worth of compressed air and then dumped a ton of chemical energy on it as fuel.
Edit did the math, and he could be putting out 62.88 horsepower in total with the kerosene if the compressor was at full throttle.
Some questions for Part 2:
- The result of the different nozzles.
- A measurement comparing force output with and without ignition.
Very little force comes from the air compressor relative to combustion. Because he can control the amount of chamber pressure he can just dial it in to suit whichever nozzle he's using whereas in a flyable rocket motor everything is calculated and defined beforehand to match.
Plus maybe using a liquid oxidizer, or would that be too dangerous?
@@randomname4726 I'm not so sure. You are probably right, but I feel like there's a possibility it's like 30% compressor - 70% combustion. That air compressor is a serious piece of equipment, and you can cut through all sorts of stuff with just the air compressor. I have no frame of reference for the combustion.
@@doubledoot yeah liquid oxygen could make grease in your seals explode. Also you can't buy that stuff but have to freshly distill it from the atmosphere with buyable liquid nitrogen. And by using 100% oxygen instead of atmosphere 80%nitrogen 20%oxygen it will get much hotter, melting your engine withing seconds if you don't have a good cooling concept
@@Dee-nonamnamrson8718 Looks like I'm wrong, he says in other comments that it's about 50% with just air. I'm shocked, I've used these compressors and while they do put out a lot of air the speed is nothing compared to the rocket motor.
The backyard scientist is becoming more aggressively unhinged every year and it's fantastic
Before you know it he will have made a ballistic rocket aimed at the capital.
@@winterinvicta He did make solid rocket fuel recently, soo. . . 2 months?
@@sampuhhupmas5666 we’ll see in february
Nile red and him need to make a collaboration 🌚
@@sampuhhupmas5666I am from the future and he did make a mini version of a missile
That was IMPRESSIVELY stable combustion for a DIY project. Well done! It'd be interesting to see one with acetylene, if you are brave enough.
*one bomb later*
Not possible acetylen is instable at high pressure.
He even made shock diamonds. Impressive
Why would it be risky it's literally just a torch.
@@patman0250 a torch would never be able to do that:
Those are super impressive results for how crude the design is
yes
Something the DOOM guy has on his bed stand
Two only fans bots in the same section
I love how everyone in the comments is looking down on his rocket design,
like any of you guys could build something better.
@Instagram User cringe
This is so frickin cool ! I really wanna try this !
please ! would be cool to see your designs for rocket nozzles put to use here.
The metal enclosure and nozzle is holding up really well
Can't wait to see your 3D printed version
NEXT VEDIO IDEA PLEASSEE
@@theautoanswerman8063 Yea 3D printing in this pressure not an option, Or is it🤔🤭
Shock diamonds, while cool, mean that the nozzle is over expanding the exhaust. Try using a nozzle with a smaller bell and you will get even more thrust.
@@dionh70 just did. He says the exact same thing
I was gonna mention this. Thanks for doing so.
Another thing is that if the nozzle is too overexpanded, it could have actually exploded/
We need more bootleg weapon development
don't we all
Yes
I love how intelligent these guys are, and yet they hammer in some screws. I love it.
@@theyeetus1428 I… didn’t? I literally poked fun at them for hammering in a screw XD
Also I’d like to see this other CZcamsrs vids if they’re similar- do you have their channel name so I can check it out?
@@theyeetus1428 who? the russian dude? he already gave credits
Man is not as far removed from ape as we like to think
@@theyeetus1428 You mean the guy he talked about and gave credit to?...
They are smart. But they also are florida men.. 🤣
What is missing is a static force test comparing the thrust of just the air, vs running. That would show just how well, or not it is actually working
I was just about to comment this
Totally agree. How much thrust is the fuel adding. Also, O2 instead of compressed air.
@@douganderson7002 You have never seen a high CFM compressor before I guess. A sandblaster would blow the trees around just like that. We know it’s adding something we want to see how much the fuel is adding.
aren’t the shock diamonds proof enough
@@aawagga6841 Yes it's adding something. The question is how much.
My dude, if you have to feed compressed air into the system, you haven't made a rocket. You've made something even harder. You've made a glorious ramjet.
nope
...no, it's just a jet engine. The defining characteristic of a ramjet is lack of compressor
If you want to consider the engine compressor as part of the jet engine, you could call it a motorjet.
Otherwise, it's a rocket, that uses a compressed air rather than say liquid oxygen.
A ramjet uses forward momentum of the craft to compress air by sheer force of speed.
I'm genuinely concerned for his safety
Dude has big Florida man energy and I cannot believe he has not been seriously injured. Especially from the videos of blowing up aquariums with boiling salt!

No it’s ok; he was wearing those blue gloves that I use when I don’t want to get paint on my hands. Pretty sure they’re good for rockets too.
@@toddbhalford the army should cover themselves with those blue gloves thingy
This video was awesome. And a fun fact for you guys, so my job is Thermal Spraying. We pretty much use the same technology to superheat, melt, and then accelerate tungsten carbide. We then coat metal parts to apply tungsten carbide and create a hard wear resistant surface.
The gases we use are compressed air of course. Propylene and pure oxygen. It makes a super hot rocket flame with tons of shock diamonds.
I feel like it would've been much cheaper to just get some oxygen bottles from airgas.
Also...graphite nozzle or something.
I do love that you made a rocket engine and used it to cut stuff.
It's never cheaper or easier when airgas is involved.
Now he posts conspiracies on twitter 🤣🤣 i genuinely laughed at that joke.

Kinda over complicated tbh
But I'll let yall think this is cool
It's so cool to see that basically the hardest part of science is coming up with something.
It took centuries to get us to planes, then years to get us to jet engines, and now, less than a 100 years after first real jet engine plane, you can make one in your backyard.
I remember when The Backyard Scientist was mostly about Oobleck and molten aluminum. Now it's "hey, we built a rocket and an induction heater to melt steel" and I gotta say, I'm all for it!

That's insanely cool, dude! Love these high-risk high-heat experiments! The fact that you were able to make an amateur rocket engine that easily is pretty cool, especially with those beautiful Mach diamonds!
If I remember correctly though the diamonds are from an inefficient nozel, meaning the exhaust could be a lot more powerful with a little adjusting.
@@youjustlostthegame2028 oh? well i would have no idea whether that's the case or not
@@youjustlostthegame2028 you are correct it is inefficiency from the nozel
Incredible. This is the best project I have ever seen, a brilliantly simple Russian solution. I have not seen a similar compressed air rocket engine capable of such performance. This is the best video ever on this channel Thank you.

Just a word of caution from an aerospace major; if you copy this video, come to terms with losing your hands before you drill a single hole. Liquid rocket engines have killed a plethora of incredibly smart people, they should not be taken lightly
Great video as always
"I am covered.. in meat.." * Skeleton inside me: "Don't tell him.." *

"I just Eyeballed it" is what you wanna hear from someone building a rocket
It's not that much worse than the NASA way. "We kept fiddling around until they stopped blowing up."
he wasn't building a rocket just the engine, fuel source was far away from it which makes it much less dangerous
I’d be willing to donate a significant amount of money towards getting you and Explosions&Fire to do a collaboration
Those things you see in the jet flame are called "dancing diamond" by the air force and are a sign of a healthy jet engine.
You don't mention it, but if you have issues with your nozzles eroding over time, try using Tantalum alloy, specifically T-222 it is a super high temp metal (higher service temp than Inconel alloys) and is actually frequently used in rocket nozzles. And it is only slightly harder than normal steel to machine. 👍

0:06 Science Boys what the heck
I’d have been curious to see how much thrust the “rocket” produced, then compare it to how much thrust was produced just by sending that huge volume of air through the tiny nozzle.
I’d also be curious how much pressure you were developing in the pipe and just how close you came to making a pipe bomb, especially when the back end started glowing red hot (and getting weaker)
It never would have detonated, for numerous reasons, the first of which being that the engine HAD a couple of openings through which pressurized gas could escape. Second, even red-hot steel is still strong enough to withstand quite a lot of stress. Ever seen the brakes on a NASCAR racecar late in the race?
6:04 Rock eyebrow raise

I don't think people come here for "good ideas". I don't think that a DIY rocket engine would ever be considered a "good idea" by most people.. The danger seems real and not acted like electroboom... at least that's why i watch TBS :D
@@chrisakaschulbus4903 There are levels of "unsafe". Riding your bike without a helmet is unsafe. This is suicidal. Rocket engines are just pipe bombs with a hole in the side. Poorly designed ones can and do explode, especially during startup. I've built rocket engines on this scale before, and I always stand at least 100 feet away behind a barrier. The chances that his engine would explode were probably less than 5%, but would you feel comfortable standing next to a bomb that had a 1% of killing you?
@@dawica "but would you feel comfortable standing next to a bomb that had a 1% of killing you?" Uhm, no? That's why i don't do stuff like that... i watch other people do it.
@@gear2902 Yes.
Yes it is, Champ
@@chrisakaschulbus4903 I think it's fine if people want to do things like build DIY rocket engines. The problem is the lack of respect for safety, which is the sort of thing that gets laws made that ruin the fun for everyone. There wasn't even basic safety precautions taken. That rocket engine being laid down and run without strapping it down had me really nervous. Sure, it was a heavy design, but even the compressed air is providing thrust and he was entirely reliant on friction to keep it in place. Even if the friction was enough to keep it from place from the exhaust, what if someone tripped over a hose? It could have been pulled towards them with hot rocket exhaust pointing at an unpredictable angle, potentially causing serious burns. If it were to start running engine rich (melting the engine) it would have spewed molten metal toward their mostly unprotected faces. This sort of stuff can be done for fun safely with some basic precautions but these guys were way too cavalier.
I love how at 6:40 he goes to stick the hot dog right into the exhaust and then realizes that's a very bad idea.
I think he rememvered that steak and he needs his fingers to do more crazy stuff. I was nervous a little when he put the hotdog there so close.
LOL yep thats exactly what happened
I am just waiting för this man to post a video about him making a whole supersonic jet to fly around.
I'm curious about what what other nozzles look like. I'm assuming the flow is overexpanded at the nozzle but shock diamonds also occur from underexpanded flow too (e.g. pressure at nozzle exit is greater than ambient). Did you do your calcs on throat and exit areas?
I'm always super impressed with the actual engineering involved in your projects. Good to see a science youtuber that actually knows their stuff, instead of slapping something together that barely works and calling it a video.
ok but something barely working still works. and it's still just as entertaining
Kevin, you have convinced me to no longer stand behind jet engines anymore, Thank you.
Hol' up.
There goes my plan for Saturday
As long as you hang onto something, you'll be fine behind a jet. Rocket? Not so much
anymore???
Jackass crew: *sweats*
I would need to see the difference of with and without fuel to see if actual thrust is being produced over the compressed air out put. Doesn't appear to have made any measurable energy increase and it's just a high pressure torch that really could have been bought for less than the scrap metal materials used.

This video is such a banger! Such perfect demos, with great voice-over, a super cool dangerous gadget and superb production value. Also, love the merch!
Can you make lighter and more energy efficient version, that could actually power a rocket
Taking into account the power of the compressor have you measured the difference in thrust when there is combustion and when there is not?
Could you please test the thrust difference between only air running through it and the engine running
Would be interesting
That is intense! The exhaust velocity is impressive.
In my misspent youth, we took apart a model rocket engine and my friend decided to put a lighter to a chunk of the powder fuel. The chunk somehow shot into his hand and bounced around causing a blister the size of baseball of form in his palm. That stuff burned really hot
The burning question: is he all right now?
Get it, because his left hand became a giant container of pus
That stuff is compressed black powder
Not to nitpick but he probably should have used a test bench. I was working on a hybrid rocket engine and my friend burned his hand fairly bad when it well… took flight.

That was the smoothest way to transition into a sponsorship I've ever seen
Had to do a double take
Great project! I would though like to know the amount of thrust being produced just by the compressed air alone, and then the amount of thrust when the gas is supplied and ignited with the compressed air.
So glad you are still alive. The steel rocket motor is really a recipe for months in the hospital or permanent time in the cemetery since it will turn to shrapnel if it explodes, think Clamore mine! If it had exploded, well, just glad it didn't since you didn't seem to test from a safe distance or include any safety processes. I so hope none of your viewer try this. This is the most unsafe thing I've ever seen on CZcams.
7:16 deleted/rare footage of the death star’s laser destroying another rebel’s planet
The occasional sparks you're seeing coming out of your nozzle is most likely superheated rust. The combination of heat, pressure, and oxygen eats through metals pretty quickly, which is a huge reason why space agencies prefer ceramic nozzles and/or liquid-cooled components.
If you inspect your rocket engine closely, I'd bet that your nozzle throat is larger than you originally drilled and that your combustion chamber has larger air holes now.

"The compressor costs $800 to rent for a week, so that's why today's sponsor is Morning Brew!" I actually laughed out loud
I'm not sure what this video is about but I just saw it came out and I wanted to say something in the comments really quick!
Same
Fun fact: Mach diamonds actually mean that the engine is less efficient than it could be. Ideally, your exit pressure exactly matches the ambient pressure, because this means all of the excess pressure was used to accelerate the exhaust. When the ambient pressure is higher than the exit pressure, the flow turns inward and creates shock diamonds. In rocket engineering nomenclature, this means that the flow is "over-expanded."
The reason you will see Mach diamonds on space-rated launch vehicles is because the pressure varies continuously from the ground into space, so they pick an engine target pressure that is somewhere in the middle to maximize the efficiency. This means that when the engine is firing near the ground, the exhaust will be over-expanded.

I wonder how much of the thrust is just from the compressed air, and how much thrust is added when the fuel is ignighted.

soda can: i must go, my people need me
I can only imagine how much thrust it would make with pure oxygen!
Most of the thrust uou are excited about is just compressed air escaping through the exhaust. This is basically a cutting torch minus the acetylene, so not as hot.
