So this is what it looks like when you know what you’re doing
But don't change the way you do your videos
we like your .... mhmmm wild production style
Hey, I wasn't expecting to see you here 😂
HX-752 is dangerous bla bla, but tomatoes are disgusting anyway 😂
If you weren't showing us what not to do, Integza, we wouldn't even be able to appreciate Joe and his work at this point.
lol I’ve been watching you both for years and you both have interesting and very different ways of approaching science 😂
BABE WAKE UP NEW BEPIS SPACE VIDEO DROPPED
Bepis is crazy
I'm up I'm up!
That's for waking me pookie
It went from talking to the wife about fun rockets into fun facts about HX 752 and reproductive systems.
“Bepis Space” 💀
The most underrated part of all BPS space is the videography. Stunning, professional work. Great job, Joey!
Agreed.
Absolutely, these are always top notch. I forget i'm not watching a big budget produced documentary.
He is musician and you can see his video music stands out from other channels music because he makes all of them and i think it is most underlooked aspect as people think he copy paste music of others .in reality it takes work forr 2 min music
yet another Joe Barnard video of all time. This one brutally shattered my kneecaps, thanks Joe 👍
You are welcome!
"Not a fun tangent," and yet PRETTY DARNED IMPORTANT so thanks for that, Joe. Good safety tip.
To my FBI agent: I’m watching this for entertainment purposes only.
Move along. Nothing to see here.
FBI doesn't care, the ones who might care are the BATFE
It’s ok FBI agents view my LinkedIn every so often. To my fbi agent this is just for funzies
Just wondering why you need this knowledge.
--Your FBI agent
@william5931 I don't. I just watch videos about random shit all day. I won't remember this video an hour from now. I'm a sad lonely soul.
7:31 this tangent is probably the most telling about your character. It’s an honorable one that in my opinion deserves way more recognition.
12:21 Dude you got me so good i was like NO STOP
then burst out laughing when you explained
I grew up with harry, used to be best friends. Haven't spoken to him since middle school, but I've followed his rocket engine tests ever since and I think it's so cool that you're using his formula!!
Out of every channel I am subscribed to, I am by far the most excited when I see a new upload from this one. Amazing videos
For those of you who don't know, 0:21 is a Pegasus rocket launch - an insane rocket that launches satellites into orbit by dropping a solid fuel booster from a plane. I used to be a flight controller for CYGNSS, a constellation of satellites launched on one of these boosters (and probably the one in the clip). Really cool to see it in the wild!
6:45 ff, Thanks for including this part. Seriously. I don't think I've ever seen another presenter take on the issue so directly and yet politely.
YOU SIR, ARE A GENTLEMAN AND A SCHOLAR!
absolutely, that was great.
“woah that’s such a good chemical, it really makes life so much easier.. what could be bad about it?”
“OH WAIT NVM”
Azidrines are bad juju, yes
-- every chemical engineer, ever.
Everything!
haha funny chemical go eldritch abomination
What could go wrong?
Awesome video and I enjoyed the tangent on the MSDS like I say at work “Better to be Safe Now Then Sorry Later”
This is spectacularly well presented. You covered a complex topic in an approachable way - I wasn't lost at any point, and you hit the safety aspects effectively and concisely, and highlighted exactly why they're an important consideration which I love to see.
Lecithin is also an emulsifier, useful for getting fats to stay suspended in water. It's commonly found in nut milks to prevent separation, as nut extracts don't have whatever cow's milk has to keep the fat particles in suspension. It's also a pretty handy additive if you want to add something like peanut butter to a smoothie, or want to make a lower-fat ice cream at home without risking ice crystals growing everywhere.
Or want to make potent weed edibles
As a researcher with a PhD in organinc chemisty I have had the conversation about chemical hazardous and risks many times . Through someof my hobbies hazardous chemicals have come up several times and trying to convince people that the dangers are real, and could have life long, debilitateing effects is shockingly difficult. Your explination of the hazardous of the chemicals your using was exelent, precise and struck the right tone. I cant stress enough how dificult that is to do, you rely are an exelent comunicator and I will definitly use this as an example the next time I have to explain similar risks.
I don't recognize said authority, As a garbage man I see hazardous organic chemistry everyday and know how to spell it.. What exactly do you research with spelling like this, We are doomed..
😂😂😂😂😂😂😂😂😂😂 much fail
Iam having an Algebra exam in Feburary, and it makes me question my life choices... but watching videos like yours encorage me to learn that shit. You were one of my main inspirations to go and study engineering.
😂😂😂 algebra isn’t even hard it’s the trig, calculus, and other shit that’ll fuck you up in engineering. Just remember with algebra most of the formulas are given already you just have to learn to plug in data.
Really good brief overview of APCP.
Id like to see you delve deeper into the more "flamboyant" additives like titainium flake, strontium, barium and the other colorful pyrotechnic nitrates and salts
These might not have a place in a space shot where any properties that compromise ultimate ISP probably arent welcome.
Lecithin is an emulaifier in the food context. It helps keep things from separating.
We don't deserve the level of detail you put into these. The sheer effort that went into filming and editing that first two minute overview was amazing.
Oh wow I was not expecting this level of depth. I was completely engaged and I am sad it’s over. I am excited for the next one and hope it’s even longer with more great info. Thank you
You have no idea the happiness of seeing a new BPS Video
This is one of the best long term series in all of youtube. I cant wait to see where it leads and the amazing journey ahead. Keep it up!!! You're doing awesome!
years ago as an amateur rocketry member we mixed solid propellant using NH4MnO4 and powdered aluminum with a 5 minute epoxy as a binding agent poured into 2" diameter by 24" length solid rockets. It was wild because the epoxy would get very hot during the curing process. Scary stuff.
12:16 Wow, my heart stopped there for a second, until the thought that it might only be sugar came through my mind. And then you said it and I calmed down again **phew** XD
my face when joe picked up the "ammonium perchlorate" and, without any context, just EATS IT-
That sugar and water with food colouring in the background looks mighty professional 😉
Always happy to see a new video for you, most of all because you do such a great job of explaining literal rocket science, but also because it means you didn't get a a visit from Raytheon or General Dynamics or whatever with one of those gigantic checks and some balloons with the caveat you don't get to make videos any more.
You could get rid of those bubbles in the mixture using a sufficiently small concrete vibrator. This is how we ensure stable solid foundations with concrete. Just know it'll cause some of the more watery substance to rise to the top, since it is lighter. I also don't recommend using this method with any fuels that are sensitive to impact or jostling.
Just an idea. Thanks for the videos man!
Man, the B-roll on this video was insanely beautiful.
Absolutely crazy that this guy is 100% self taught. He started this channel literally from zero.
Brilliant was an excellent choice of sponsor for that video! On the other hand, AG1 could have been one since it was also about chemicals that could neutered you! /s
It's fun how so many propellant mixture names are full of puns and easter eggs that reference each other.
Your video series has come a long way Joe. Quality work here, you should be proud!! You may not realize it yet but you will inspire children today with science that will have profound impacts on our world in the future.
These videos have been getting better and better!
Hey Joe, rocket scientist here, wish I’d had this channel available when i was studying. learn by doing - yes! The studies only touch on a lot of stuff which you’ve absolutely dived into and really got skilled in - i love your videos!
You mention the use of MDI as the curing agent for solid propellants. Now I work at the solid rocket manufacturing plants in Utah where we all sorts of different propellants. And of all the formulations I know of, none of them use MDI as a curing agent. Also the curing agent we always went to in college was D.E.R 331 or DDI curing agent. Those are much more readily available and are not as toxic as MDI.
Taking a break from studying for my Thermal Rocket Propulsion exam after getting wrecked on a question about a Solid rocket motor and what do I see in my recommend. More solid rocket motors. My life is a sick joke haha
Edit: in my textbook it's De Vielle's equation as well, guess that needs updating
Man there are a lot of science, experimentation, engineering RUclipsrs I watch. You're among those top of the line straight up madman.
There are the popular science guys who are just using cool tools and materials like vacuum chambers, ooblack, ferofluids, liquid nitrogen to make experiments done a 1000 times before.
Then there are awesome builders, creating jets, airplanes, plasma, laser, chemistry, high voltage experiments and many/much more. Very extremely cool projects, but mostly for themselves and RUclips, without a clear goal.
And above that there are the madmen. Off the top of my head I can think of "Thought emporium" and yourself. Doing stuff that requires some brutal scientific research and dedication and a clear goal in mind.
I am not an expert I have just been interested in this kind of content since the beginning of RUclips. I really appreciate what y'all are doing ❤
YOU TAKE THE HTPB, IDP, ALUMINUM AND MIX AND ADD THE PER-CHLOR-ATES! YUM! 🎶
Ever consider doing a video with one of the chemists RUclipsrs on how to test and purify your input materials? There has to be a way to verify the quality of the stuff you're getting before jamming it into an explody tube.
Last semester I studied this things as rocket propulsion system had 5 units solid rocket pro, liquid rocket , hybrid then electrical propulsion ...damm it was ...main highlight was learning regression rate in hybrid and liquid rocket specifications...thou we couldn't study entirely but got an raw idea of rocket propulsion system as an aerospace engineering student...now after seeing this video I can literally remember wht I studied and can understand nowww more easier ❤... amazing mate....if in case you conduct some free online internship( mainly I am from India ) please notify us because you are an excellent teacher and scientists
It`s such a joy to see how far you have come.
From shooting your first test rockets to this, always blows my mind.
BONGO SPACE PROGRAM POSTED LETS GOOOOOO
It's awsome seeing how far you've come, from testing thrust vectoring with standard hobby motors to literally msking your own fuel for a space shot!
Also eating the sugar really got me!
Im telling you, BPS and Copenhagen suborbitals should team up, place your space shot on top of their spica instead of the capsule for a bargain bin vanguard rocket if you will lol
Very good video. Excellent pace, no irritating Adderall narration, super interesting stuff. What all RUclips videos should be!
I remember when you weren't feeling so good and you had to spot for a while. Glad this is where you are today!
Love the videos I love rockets and the science behind how they work big or small rockets
I love that when You read the script You are moving Your head so it looks more energic and a good way to cover the eye movement.
Loved the video
A dead straight concrete tunnel.
3 miles long.
Pointed on a slight upward trajectory from start.
To avoid unnecessary lateral g forces.
Reduce atmosphere slightly.
Install mag-Lev rails around the outer diameter of the tunnel.
Accelerate whatever you like into space.
Weight would not be a problem.
I think lead lined space ships might be nice.
Congrats, after more than 5 years you are my first youtube comment. Thanks for finally describing the full details of propellant design, interesting stuff. There's no protecting idiots from themselves anyway, if they are determined enough. Best you can do is explain why its dangerous instead of just giving them an instruction manual. Which you did.
As a former research chemist, I'd have to disagree about avoiding toxic chemicals on principle (I've used much, much worse), but I guess I wouldn't want those in my garage. Nice channel. Good luck with the spaceshot!
I just love seeing the one upload per blue moon come from this channel. Hopefully some day you're able to reach said blue moon with these amazing rockets!
thank you for the appropriate warning concerning the risk potential of the educts and thinking about the product and cleaning and disposal.
intriguing!
I agree with ball milling for the AN.
personally I‘ve worked with gas mills and far finer grain size range.
Those zoomed in shots of the suppressant, aluminum, and other motor ingredients make them look strangely appetizing haha. Anyways, great work Joe!
Nice work Joe! Looking forward to seeing the data on that motor my buddies found out at Black Rock desert last year :) hope it’s made its way back to you by now.
Bro, I don’t even need to see your thumbnails anymore. I just click as soon as I see BPS… Your production quality these days is phenomenal, I can’t believe you don’t have 2M subs yet.
Cool video man, I can't wait to see where you take this! One small but very important correction, the aluminum does NOT act as a fuel in the propellant. Fuels expand into hot exhaust gasses that take up tremendously more volume than their solid original state when they are burned. Aluminum does not do this at all. When it oxidizes, it does not expand and does not get hot enough to even turn into a gas. It's real purpose is to release lots of heat as it oxidizes, which in turn expands the exhaust gasses and increases pressure, therefore producing higher thrust as the gasses exit the nozzle with greater force. In this way it acts very similar to a fuel (both ultimately work to increase the pressure of the exhaust gasses) but do so in very different ways and have different side effects as well. In apcp propellants, the fuel is the binder, but also unintuitively the AP as well. When AP breaks down it releases the needed oxygen to oxidize and all that good stuff, but the molecule also breaks into a burnable fuel. This is why AP is such a great choice as an oxidizer, even though there are plenty of solid oxidizers that are better at releasing lots of oxygen, which on paper sounds better.
AFAICT, there really doesn't seem to be a clear consensus on what "fuel" means in the context of solid rocket propellants, and many seemingly authoritative sources (e.g. www.ncbi.nlm.nih.gov/pmc/articles/PMC8587658/) as well as less authoritative ones (e.g. Wikipedia) seem to classify all reducing components of the propellant mixture (other than trace additives, perhaps) as "fuels", if they don't simply use the words "fuel" and "propellant" interchangeably.
For bipropellant liquid fuel rockets, there's a well established distinction between "fuel" and "oxidizer", those being the two liquids stored separately and mixed and ignited in the combustion chamber. (And yes, aluminum _has_ been tried as a liquid fuel additive; see e.g. Clark, John D. (1972), _Ignition!_, p. 180.) In solid rockets, however, the propellant is all one more or less homogeneous solid mass, so that simple distinction does not apply. The various substances making up the propellant grain can certainly still be classified using chemical terms, e.g. as oxidizing, reducing or inert, although - as you note - this classification isn't perfect since a single substance such as AP can contain both oxidizing and reducing parts. However, "fuel" isn't really a term used in this chemical classification. The closest thing, perhaps, is "reducing agent", which metallic aluminum certainly is.
Anyway, while gas generation is certainly an important (arguably _the_ most important) aspect of rocket propulsion, AFAIK there is no concise and established term for "a substance producing a gaseous exhaust when combusted as part of a rocket propellant." And even if there was, it would presumably have to include both oxidizing and reducing compounds, since both can and do contribute to the exhaust gases.
Part of the complexity here is that the actual composition of the exhaust depends not only on the individual elements and compounds present in the propellant mix, but also on their ratios and on the temperature and pressure of the combustion process. While we can certainly say with fair confidence that e.g. aluminum pretty much always gets exhausted as solid particles (of aluminum oxide or, if combustion is incomplete, aluminum metal) while e.g. hydrogen and nitrogen pretty much always end up as gases (H2 / H2O / N2 / NOx) in all but the most fuel-rich (sorry, reducing) combustion conditions, other elements such as oxygen and carbon can go either way depending on what (if anything) they end up reacting with. And even when a combustion reaction produces gaseous products, that doesn't necessarily guarantee an increase in pressure: for example, the combustion of hydrogen with oxygen (2 H2 + O2 -> 2 H2O) has gaseous products (at typical rocket engine temperatures) but actually decreases pressure, since three gas molecules go in but only two come out. The heat generated by the reaction, of course, generally more than makes up for it, but that's still a big part of the reason why hydrolox rocket engines pretty much always run very fuel-rich: you get a much better specific impulse if most of your exhaust is uncombusted H2 rather than H2O. (The other reason, of course, is that _too much_ heat tends to be bad for the engines.)
We going above the stratosphere with this one 🗣️🔥
Great bit on toxic chemicals really informative 👍
Lecithin is an emulsifying agent, used to mix two or more liquids that are usually immiscible. You can use it make mayonnaise, very spicy mayonnaise.
Never thought i'd see the day where Bernard actually makes Propulsion Systems.
New to this channel. Amazed at what you are doing. While other RUclips's talk about rocket science you are actually doing it.
Super interesting Joe. Thanks for making this.
This will help my rocket team for its investigation for our rocket, a lot of thanks BPS SPACE
“This is a piece of Ammonium Perchlorate, also known as the spicier form of those silicon balls you should never eat.”
you make all of this sound so easy to understand. i wish some of my teachers would've been like this
Can we appreciate the stop at 18:08? That is actually stunning it looks like a nuke on a test stand lmfao.
Of course it is sad that it went kablewy but cool as heck!!!!
Holy crap, very impressive. Been a pleasure following you on this journey. Awesome work dude.
Insanely well documented.
Watching your progress through all this has been incredible. I am so eager for the stage when you move on to liquid-fueled rockets, stepping away from working with these highly dangerous mixes in a workshop. Although liquid rockets are famously incredibly hard to make not explode, at least the dangerous stuff is only present at the test stand!
There's a youtuber making a liquid rocket made out of a beer keg which I'm eagerly awaiting the completion of, it looks really cool
Please make a hybrid rocket with blue tape as the fuel.
You almost got me when you ate the "Ammonium Perchlorate".
Joe Barnard! This generation’s Homer Hickman! I salute you, sir!
I feel like "Risky Batman" is definitely a clever play on words in contrast to "Reliant Robin". I see what you did there.
Waking up to a new BPS video is the best feeling!
(I only now realized how similar our logos are)
Been here since the days of Signal R2, Nice to see you go for spaceshots. May the skies be clear and winds be low!
nobody is talking about the mustache. RIP mustache, you were incredible.
OH MY GOD JOSEPH BARNARD THANK YOU
Been here 4 years since I discovered u as a little kid. Still following with interest... Can't wait to see the space shot
With all the chemicals in use, I was almost expecting a NileRed cameo
Nice video, even though I have no intentions of ever building a rocket, I still enjoy watching your videos.
Amateur rocketry is cool and all, but I'm mostly here for the 100yr old Royal Society drama. 🍿
OK. I'm pretty invested in seeing you make it to space. If you need parts, say the word!
Though I totally relate if you want to make everything yourself 😁
Oh man, I'll have to think of something worthy of the IM shop :)
Wish I had this skill and brain power, I’m just now using fins with mobility but even that barely works. Keep this awesome stuff up!!!!!!
As a chemist, hearing a layperson discover “supplier quality is a thing”, “there’s a ton of variables”, and fumble through the pronunciations was a treat 😂
7:45 I could watch that all day
Joe man, I love that naming convention. Great work!
It’s been really cool seeing the scale of your projects evolve over the years nice work!
This video is of such high quality, it feels as if Apple is announcing iRocket!
Dude! So much detailed information I will never apply on anything in my life! But intriguing anyways
I love your videos. Joe joe joe BPS space
For those wondering Lecithin is often used in processed foods to stop water soluble and fat/oil soluble ingredients in emulsions from separating.
It's great to see you making your company name accurate ^_^
@TechIngredients would love this stuff!
How to have a good morning?
BPS Space is here
I did not understand a single word but i am completly amazed.
IDK why but that slice at 17:47 looks TASTY
Sutton has a good-sized section on this. I'm considering a Karmann breaker, and so far, OpenRocket says a 3-staqed rocket powered only by N-5800 can go that 100 km line. Since I want to get it back, the upper stage has a graphite nose cone and cargo bay and fins. The rest is carbon fiber, 4.024" off the shelf. As for recovery? I'm still working on that, but Regallo is a very attractive method. I'll build an Estes BT-80 size, first.
I'm learning a lot, here. Keep up the good work!
THANK YOU for talking about safety!!!
I was sitting there watching your video on my big screen TV when my wife stated "That's Elon Musk's son right? And he's also into rockets, what a coincidence". When I finished laughing I told her "no, I don't think so".
