I never thought about the backpressure of a hybrid rocket acting as a safety feature. That's pretty neat.
I found that really intriguing aswell, im wondering if that precise pressure regulation improves nozzle performance in any way over an unregulated engine
@@youngbloodbear9662 In this case with engine 4 you can clearly see it hinders it.
All the black smoke means there is unburned carbon in the exhaust so lost performance and efficiency.
If you want peak efficiency you have to have some kind of controlled valve.
Yeah. Although that may be a problem if you want to get more oxidizer into the combustion chamber even when the combustion chamber's pressure is at or above that of the oxidizer tank.
@@nukularpictures I think that was because either the pressure was too low to feed the larger motor or that self correcting mechanism developed a feedback loop in that case oscillating in pressure
Holy shit, I used to watch your channel all the time when I was younger. Time to binge.
I love those shock diamonds. Spent years as a test engineer in aerospace - most of the time, we'd do simple production testing on commercial jet engines. But every once in a while, we'd get to test a fighter jet engine. When one of those goes to max AB, you'd get six or eight shock diamonds, and the sound would be so loud it would be hard to breathe.
They look like standing waves just that I have never actually seen a standing wave, just heard.
@@jakx2ob Scott Manley does a pretty good segment on Shock Diamonds.
How much a jet engine cost of making?
@@soumadipkoley581 you can make a valveless pulsejet for free if you have the skill to build it. A fighter jet engine on the other hand is probably in the $100,000-$1,000,000+ range.
Funny, near the end of the video, I was thinking of posting a comment asking what’s the physics behind the apparent standing wave with diamond shaped nodes. I should have known that would be explained in the video and by other commenters.
16:44 "I'm deaf in one ear" - "What?"
The most wholesome kind of comedy. These videos are an incredible treasure trove all around.
16:38 - 16:44
I love this technique of getting curious officials off your back... before they get a chance to disapprove, just dump a bunch of words on them that make them feel too under-qualified to get in your way.
Undoubtedly that's part of it, but there is a positive effect when you quickly engage their curiosity. What percentage of the population doesn't actually want to see a rocket?
@@TechIngredients Good point. I’m sure you have plenty of neighbors interested to see what’s going on at your place for the 4th and New Year’s Eve
The guy is an educator first and foremost. His inclination to explain things isn't an attempt to bamboozle a rube. I think he genuinely feels like if someone understands they'll come to the same conclusion.
@@freejulianassange3143
Hey Julian ! How did you escape from you prison ?
6:45 I just love the comedic timing of the biker in the back. "Let's just make sure... nothing?... Nothing."
I'm laughing so much they both missed him 🤣
You misunderstood. That was their neighbor Mr. Nothing. Those Nothings are always right on time.
Damn nothings always ruin my shots too. 😃
Maybe the bicycle guy is the roving watcher
@@riteshr.k.fatnfine3004 he probably is. That was my second thought. It's just too funny if he wasn't.
Please never stop making videos. This is the level of education I wish I had in school.
agreed! Or even out of school! We have a rotation of youtube at the hackspace 24/7. Tech ingredients is definitely on the playlist at least a dozen times. It's inspiring.
yeah, this would definitely have kept me in school more often!
Thanks for not “safetying” these videos up so much that they are unrepeatable. Also thanks for helping to inspire the next gen of a hopeful space faring civilization!
um quite repeatable with any brain power
@@TheWhatman21 Reading is hard without brain power tho
First time I've seen or heard of "shock diamonds." I bounced in my seat. This channel is awesome. There's so much stuff to learn. I wish I could learn and apply everything in my life. Keep it up!
You haven't watched a rocket firing before?
I can recommend a few SpaceX UA-cams...
You can. Absolutely! I felt the same way watching hobbyists build electrical circuits and stuff like that. So I took to the internet, learned what I needed to find out what parts I need to get started, bought the parts from aliexpress, and then after a bit more learning I found some more resources and it just took off from there. But make no mistake, if you want to take up a hobby you can't just watch a video and expect to be doing the same sorta stuff right off the bat. It's going to take a lot of time and dedication. But a lot of tinkering, too. Which is where you get to have fun. Though I find the learning fun, too. And you seem to as well. So just learn what you can, when you can, as much as you can. Take every chance you get to practice.
As far as the practice goes, I can think of 2 things you could do. Though I've never done anything hands on with rockets before, so my knowledge in this is limited. If you're afraid of breaking something and starting out fairly new, I'd suggest playing Kerbal Space Program. It might sound silly, but the game uses a lot of real life physics and you can take actual math from rocket science and apply it to the rockets/planes/space planes you design and fly in the game. The more you learn about playing the game, the more you end up learning about rocket science. The more you learn about rocket science, the better you can play the game. It's an amazing balance of fun and educational. Whether you just blow stuff up or recreate a missile, or build an actual rocket to another planet, you're always using (and learning) real science either way. And there are TONS of UA-cam channels about how to play, ranging from extremely technical to "I'm just here to blow stuff up" levels of complexity. But I'm sure you already know about KSP if you're interested in rockets.
Another thing you could consider is taking up building model rockets. It's pretty common as far as hobbies not involving electronics go. You could buy everything you need to build your own rockets right off the internet. Again, I've never done this so I don't know where, but it shouldn't be hard to find a place. I even recall finding a place to buy rocket motors online years and years ago so there's probably a place you could find on Google. Or AliExpress or Amazon might even have something. But your best bet is to get it from a proper store that actually sells model rockets. It might cost more, but believe me you don't get the best quality stuff from Amazon or Ali Express.
And yeah, you could just learn what you can about them from UA-cam. I'm sure there are tons of videos on the subject. Or from other resources. Don't be afraid to step outside of your comfort zone and (at least try to) read a textbook or watch a lecture. It might all be Greek at first. But you give it enough time and enough persistence and you'll be amazed at what you can learn given the right resources. And I need to stress DO NOT be afraid of the math. It's actually a lot more fun to learn math when you actually have an application for it. I know it puts a lot of people off because you need a solid understanding of math for any science. But it's really not that bad. And I failed the CRAP out of math in school. So don't let school make you think it's hard or painful. It's just hard or painful the way THEY teach it.
Best of luck to you. And just keep it up. Even if it's a slow pace, if you keep it up long enough you'll be doing stuff you never thought you could. Believe me, I know.
They're not actually shock diamonds they're mach diamonds which is the thrust is coming out faster than the speed of sound around seven to eight hundred miles
Awesome huh!! "Mach Diamonds" I jumped up to. Never those on Rocketry. SO SO cool.
Those shock diamonds are beautiful
I was thinking exactly the same thing!
Shock diamonds actually represent inefficient nozzle expansion (unavoidable at sea level tho)
@@kalancosta7650 No. it represents the reality of physics as we know it today. You can’t model the nozzle to get rid of it without hurting others performance parameters. Engineering is always about making the appropriate trade offs given the constraints.
@@rplatt9829 She may get ... sunburned.
@@AndySpicer This doesn't seem entirely true. You can get rid of them at certain altitudes. The shock diamonds are a result of the pressure mismatch at a given altitude. Ideally the nozzle would be optimized for maximum efficiency in a range of altitude. For long burn motors this is critical, but on smaller motors that only see a few seconds of burn, it seems it would be better to have them be slightly over expanded at ground level and gradually equalize before burn out. There is a calculator that will help design nozzle geometry. Nozzle by AeroRocket is one such program.
That bike must have been scripted. Perfect timing.
All clear... "hey I wonder what those guy's are doing...?
Spooking cyclists with loud noises is good for the environment.
There was a cyclist in the last video too.
In my mind, there are two people that adhere to a rigid schedule. One cyclist, one mad scientist.
I was wondering if the cyclist was part of the range safety crew.
It was overlaid. In other words, it didn't actually happen while they were sitting there, it was post script.
This whole video made my day. "All clear" (as bike is riding by). The safety sandals the newcomer had...all of it. Love your videos. Quite impressive!
That was hysterical
😂
"Nothing?"
Bike Rider: ( ͡° ͜ʖ ͡°)
"Nothing."
He probably thought a race car was about to run him off the road probably scared the crap out of him
As safe as he was on his own property testing rocket engines there's always those few people who are bored and need to insert themselves into others affairs! I love this channel and have learned so many things from it! Many of us when we were kids got those starter science kits, I remember mine! I've never lost that joy an thrill when I see cool experiments like Tech Ingredients!
In the end, the dude actually looked like he was just curious and open minded, which is actually much more unusual these days!
Always good to figure out what's going on.... I mean I appreciate it but it's all legit.
The neighbors were overwhelmingly sweet. In the US exurbs, there are lots of people doing alright for themselves. They have some property , and some wealth,, but they don’t know their nextdoor neighbors at all.
Maybe one of them has a dog that won’t shut up all night - maybe one of them plays music a little loud - or works on their motorcycle early in the morning. Everyone has enough space , so no one makes a stink about it, but its the human condition to want to know more about your surroundings - what are you neighbors up to?
They certainly weren’t making trouble. It just stinks that public spaces - like the actual “pub” / public house - don’t exist in america, so you need to be intrusive just to be friendly. I helped a stranger (a pregnant mom, pushing her son in a stroller) carry the stroller up to her front door. She kept saying “Im so sorry to ask for your help, It’s rude” and I wanted to start crying. You should be able to ask questions of your neighbor,.

Would've been better, if it were someone pushing a baby carriage!
Me: I made some smoke bombs for the 4th.
Tech Ingredients: I made supersonic rocket mach diamonds in our front yard.
You should check out their older videos on making very good smoke bombs as well as colored smoke bombs.
@@skuzlebut82 yep, I got my smoke bomb Rx here! Thanks...
You're one of those people who have a thorough and deep knowledge of how things work ans you make them work most effectively and it's a sight to behold. I love watching your stuff. Keep it up man... Keep it up
I also *LOVE EVERYTHING ABOUT THIS VIDEO!* From the entirely over-engineered ignition system, to the shock diamonds, to the fluid dynamics of the low pressure zone pulling in the gases and air...
So much awesomeness and beauty in a single few moments!
*GLORIOUS, GOOD SIRS, GLORIOUS!*

"Wanna watch?"
"Sure".

I thought FBI agents was going to pop out from that car. Thanks god it's just a lovely old couple.
@@alexchan3287 Who knows what that lovely old couple is going to say at the next town hall meeting about noise ordinances and such?
@@alexchan3287 fbi don’t drive German cars. But the CIA had a lot of Germans in it after that ww2
LMFAO
In the next episode: "Bearing and range finding with DIY microwave radar system."
That would be cool.
It also cooks great lasagna,lol....XD
check out the MIT coffee can radar system, there are full instructions.
The joke is that such a system would provide guidance for a weaponized rocket, yes?
@@Oberon4278 yes
I have friends and colleagues that are involved in rocketry, at first I didn’t quite understand the thrill. Once I started to see it n detail then I got it, and your channel has helped me understand it a lot. Thank you. Phil
I keep introducing people to your videos, and the first thing I describe you as is "tech uncle"
You're a mensch. I hope to keep watching your experiments for years to come. Thanks to you and the team that put all these projects together!
People - I'm here to see actual rocket engines being fired.
Also people - The beeping is annoying
People are "amazing".
I don't like when videos do random annoying sounds for no reason. In this case it makes sense.
Its like. You look at your phone to make sure its save. and in this moment 6 eyes havent seen the cyclist at 6:50
im actually wearing headphones and the beeping isn't that bad.
i think those people just needed something to complain about XD.
They're probably having flashbacks to the speaker building video where MP left a 1khz tone generator going for half of his explanation.
@@bdblazer6400 "And we're good" 🤣
I stuck to the parameters while I scaled up. Way up. I'm stuck in orbit and I'm not sure how to get back. Looking forward to your future episodes on reentry procedures. Thanks.
That's one hell of a wifi signal you got there........
@@evolicious Starlink?
Have you happened to eat a lot of beans recently?
Don't worry, orbital decay will bring you back.
Well, you back yet? (In one piece) . Or did you keep firing subtle vernier rockets to maintain your altitude?😄
Finally, I've been waiting for this :)
Only thing I'd suggest although probably a little to nerdy for most of your viewers is that it would've been nice to see burn temps and outer cylinder temps of your engine, plus having a force gauge reading on the screen when showing the slow motion replays, watching those pulse diamonds move back and forth and the changes in force might've been interesting.
I absolutely love it that you have understanding neighbors, I wish I was your neighbor I would be fascinated to come and watch some of your experiments, and thank you for explaining about the shockwaves I’ve always been curious about that, you had a very simple way of explaining the shock bands that I never really understood before, once again I absolutely love your channel thank you so much
One of my favorite Parts was in the first test when you had secondary ignition, I could see there was so much force that it pushed the trailer and made the chains tight. Amazing
Love how the Neighbor just joined instead of complaining. Awesome Show, thanks! Would love to see more "Starbase" related Content from Tech Ingredients!
You have yet to produce an episode I haven't *thoroughly* enjoyed. I've learned more things about more topics here than I can count. Just enough safety, great demonstrations, just enough background and rationale, detailed demonstration of repeatable designs and procedures, it's all solid.
Fantastic!
That about covers it.
Excellent!
- I love how the smoke gets drawn into the flames (simply spoken)
- I love how the visitor stayed, watched and jumped..
Me thinking: those trailer leaches are way over the top... oh crap! This tiny thing is actually driving the entire rig!
Me: blessed by the fulfillment of joy.
Really impressed with the production quality. You guys are seriously leveling up!
this channel just hits the right spot sometimes, such amazing knowledge and experiments, never fails to deliver
Next time you anchor a trailer, make sure that the chains are laying on the ground. The higher up the more leverage they get to bend those rods. And once they are bent, they will come out easily and your trailer will move.
I don't think there is much to worry about with the force generated. The trailer probably wouldn't move very far with no chains at all
Good God Man, Relax a little
That's good advice for a project I got coming up where it will matter, thanks.
@@jmccormick8732 still good to know
@@davidmurden1831 it might rotate which could lead to a dangerous situation
Oh look at those beautiful MACH DIAMONDS !!!
I thought mach diamonds show that it's not making maximum thrust? In other words, they look cool, but you don't necessarily want to see them.
@@TheM750 Mach diamonds show that your flow is hypersonic, they are unavoidable in high performance engines. All SpaceX motors do it as well. the mach diamonds are a side effect of the pressure wave converging and diverging. When they appear lopsided or "twitch" back and forth it shows minor inefficiencies but that is to be expected from a hobbyist setup. The fact that he even achieved mach diamonds is staggering and incredible.
@@TheM750 it is overexpanded so it is not at maximum power BUT rockets have a tendency to go high very quickly. So if you want the max performance (and stability) you will over expand at start, which will turn into slight under expansion at the end (due to lower pressure).
Over expansion is also good to produce visual shock diamond on purpose so you can measure the speed of the flow just by looking at the exhaust. Practically all rockets at sea level are over expanded (there may be even more reasons).
If you over expand too much, (use a massive nozzle), the flow will separate before leaving the nozzle and will most likely try to crush it it usually oscillates too. SpaceX tested vacuum engines with maximal expansion at sea level, and you can see some surprisingly small but dangerous flow separation there.
@@dannykerby9580 It sounds like you think I'm criticizing him or their design, I'm not. I just remember reading elsewhere that it's a sign of inefficiency at specific atmospheric conditions and was curious if it meant they needed further refinement of their nozzle design or if it was expected (or both).
Staggering and incredible might be a bit hyperbolic, but, it does look cool af.
@@adamrak7560 Awesome reply, and great information, thank you.
"rockets have a tendency to go high very quickly" - Ha, hopefully!!
Have been really looking forward to this video. It didn’t disappoint. Well done!
I could watch stuff like this all day, I wish i had as much space, money, time and knowledge like you to do these things. But I don't so I just watch your stuff.
The quality is amazing. In depth explanations, good safety protocols and interesting topics. I'll stay subbed for sure!
This is definitely one of the best channel i've ever seen, without a doubt.
"There's going to be very loud noises here..." LOL Very impressive!
That "Whaaattt?" at the end is a classic!
Great work & stay safe!
This has to be my top physics/science/chemistry channel!
Thanks for all your hard work and risks you take to share the knowledge!
You're welcome!
You guys have so much fun! Glad you are also sharing it with us! =D
Great video, as usual! Thanks for all the effort and work involved in making and sharing these awesome videos.
Can’t wait to see the big rocket finally shoot that trailer into the sky!
They have started to optimize the aerodynamics of the trailer by adding those two anchors.
Starman's car had a hitch... Right?
I love this DIY sidewinder videos! Thanks for all the info!
You not only are brilliant but have alot of fun doing these things. Its a pleasure watching your creative process.
this is one of the best channels on youtube bar none. thank you for sharing your knowledge and experience
This channel constantly impresses me. I'm impressed by how much yal impress.
The fact that you are getting mach diamonds in your yard is so very impressive...well done sir 👏 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
Once again. This is the best channel on youtube. Those shock diamonds are just stunning.
Also remember to click the bell!
absolutely love the detail and knowledge you are willing to share, thank you.
The research, diligence, and methods set this channel apart. Always learn something new and trust the science and methodology used in the testing.
Fun and interesting to hear about the shock-wave bands, that are produced in the super-sonic expulsion, too!
excellent... that stuff will put a smile on ones' face. I give you and your crew the highest marks.
peace.
Thank you to both of you!
I will likely never construct a rocket engine, but I have thoroughly enjoyed watching your entire rocket engine series. It seems to be some of that knowledge that should be preserved with a hard copy. A digital copy on a zip drive inside a small metallic case could be sold in an online store, assuming it's all original copywritten content.
Enters the blockchain; mint it as an NFT on blockchain: copywrited instantly forever. It is how things will be done in the future.
100 years from now somebody will find an ancient copy on a USB stick haha ;)
Engines like this have been commercially available at the hobbyist level since the mid 1990s. They require a bit of effort to acquire but they have a reloadable rocket engine with miniaturized NOS tank with a pyro valve specifically designed for fitting inside a rocket body. The knowledge is already out there.
@@cacaokingdom3122 The point was doing it for yourself... Really, all you can say is I can buy that?
I love this guy and his experiments. Especially the sense of humor when son says I maybe deaf.
I loved the way that your young colleague just sticks to business while you do the P.R. Well done! Love the series!
You remind me so much of my old science and technology teachers. Make sure you have a bunch of knowledge and a good bit of danger to keep you glued to the classroom. I had an awesome teacher.
the title kinda reminds me of when i first started modifying fireworks and making my own pyrotechnics growing up..... but i was actually arrested XD
By far highest quality content
Fantastic results! the standing waves in the exhaust gas look beautiful!
Love this kind of content! Thank you for putting so much effort into your videos.
Most people are awesome and just curious about whats going on, as this great couple was it was something fun and unexpected they came across and it was something that really created a memory. This afternoon will be something they remember for a long time.
This is why i love people, sure everyone is not that great but most people are and they make it an even better experience for everyone included. You made their life a little bit better, and you also made your life and the life of your family a little bit better and everyone wins.
I'd love to be walking down the street and find this happening. I'd watch the shit out of it
I love the deep dive videos you guys do. it's fantastic. Edutainment at it's finest
Your'e the best channel on youtube , the amount of build and details from start to finish is phenomenal . Keep em coming 💪

@@jupa7166 WHAT!?

I was just a little annoyed by the music drowning out the sound of the rocket because I find it as interesting as watching them light up !
After all it's part of the result. And those diamond shapes are pretty cool.
Your awesome! All we can ask for is that ALL teachers have the same enthusiasm for teaching as you do!
Wow, I thought the trailer was going to take off!!
Thanks for sharing.

Holy freakin' heck that's a lot of thrust outta that tiny thing!! That was a lot of fun! Thanks for the awesome videos! :)
You should cover aerodynamics for rockets next
I would really love to see a follow up video giving an analysis of the motor burns.
Ps Thanks for making this series. It's my favorite series on UA-cam.
I agree, to me that would be just as interesting as the video itself. A little more of a deep dive into issues, and potential improvements would add a lot of value to the series. Science is often iterative, and builds on successes and failures as well. I'd like to go along for the ride!
That sound was beautiful. Can only imagine how it sounds in person!
Amazing as always. Keep up the excellent work and love to see every video!
He was fine, having a good time.
Notice: For an accurate load cell reading you need that trailer to be unmovable.
In fact, on second thought, no tires either because they will always absorb some movement and spring back since the restraint is at an angle, tires allow for some of the force to be displaced to the vertical vector and some movement horizontally also. Consider a steel square tube filled with concrete on each side of the driveway to also hold gates some day when they grow up, just use one of those. The whole design of a load cell internally also is to measure force in such a way that movement is kept as close to zero as possible.
As it is, with the trailer lurching and slamming to a halt, the chart/graph over the course of the firing does not always show just force but is influenced by some of the force transformed into kinetic energy, movement of the trailer and also the rebound after the chains go taut for example. More specifically, the reading is too low while the trailer is moving and suddenly too high the moment it stops, only accurate when the restraints have stabilized which is a significant time after the initial firing of the rocket engine.
Trust those who have experience with physics and mechanical engineering and sensors for decades like me.
I doubt you are louder than my neighbours, but they fly f-18 super hornets and like to practice hard and fast take offs in pairs. :-)
My only question was about those hotter areas in the exhaust, but I'm glad there were explanation right at 15:09. Great video, thanks!
Most impressive series. Thank you
Is there a reason that no decibel meter was set up on your desk? Would be fascinating to know how loud those rockets are.
Yes! More telemetry is always better! Would be interesting to get sound meters at multiple locations, temperature sensors on the surface, maybe even pressure sensors on the gas injection to better characterize the behavior of the backpressure!
it would burst into flames and then explode lol
yes please do that :D
Would be awesome too if he set up a camera/microphone far away so we could hear what it sounds like from a distance.
Those are some sexy thrust diamonds.
Great video. Thank you for all that you do. Your channel is pretty amazing to say the least.
That was entirely satisfying to watch and listen to.
When I saw the mach diamonds in the exhaust stream I knew that was a quality build .

Well that was great, thanks for posting. I think I'll have to go back and watch the preceding videos now. Love the mach diamonds!
Did anybody else feel a slight twinge when the countdown didn’t match the timing of the beeping? 🥴😵💫
Also, this series has been amazing! This guy could science anything, and I am loving it!
@mike d - same
Yup
I didn’t understand why you include background music on some parts of the video. The content is amazing, you don’t need the music distraction.
High speed cameras don't record sound. Yes, Slow-mo Guys and Smarter Every Day add Foley effects over their slow motion shots. Silence can be as eerie as odd music choices.
@@Markle2k Exactly this ^
Those shock waves im the rocket exhaust are really satisfying to look at, especially in slow-motion.
Thank you. For the great content. An answering the question about the bands in the fire. Exiting the rocket
neat, looks like got some resonance going on with supply. curious if that effects performance. and the nozzle looks to be over expanding, so can get more power by adjust thing that. Also super curious what the difference between it ignited vs not ignited with Nox just flowing out of it.
Interesting, I too was wondering if an amount of unburnt grain was being ejected or if there were variances in the oxidizer supply
With solid rockets remember you can engineer your fuel grain like an onion and reduce your impulse when the surface area increases by formulation.
I would think you could do that with a hybrid as well.
Hey man here 2 years late! I’m officially your biggest fan. I’m fully prepared to share your videos with everyone I know.. keep going!
