From what I heard, this type of cycle is called RUD (Rapid Unscheduled Disassembly) Starship SN10 used this to make a reflight in under 10 minutes after landing! Now that's an impressive turnaround time.
honestly your content is beginning to feel more and more like curriculum as it gets fleshed out and cross referenced. very few people would have the stones to go into as much detail as you have done. thank you for caring about getting it right. you are a researcher and presenter of quality sir.
@@itzzitzz Nope, it's amazing content, but it's mostly surface level. It's just right to get you excited to delve deeper if you want, but its not gonna help you make a rocket engine. Like he claims, the purpose of Tim's channel is to bring space down to earth for everyday people..
We use “rocket science” as a term to indicate something is extremely complex. And it is, but you present it so well that I understand it. You’re a legend Tim.
Rocket science is NOT complicated. As you can see it's all very simple. If you look into the operations of a Modern Super-Turboed Diesel engine in depth. You will see it has more moving parts hence it is more complicated.
This, Tim Dodd, was a tour-du-force. Your attention to detail and the effort you put into ensuring that we (your loyal audience) actually understand what you are trying to explain to us was obvious. This video was a really good primer about rocket engines and the diverse choices that engineers and designers can make when trying to "build a better mouse trap". Thank you.
I'm overwhelmed at how good this was, Tim. At first I thought "well, this is obviously a setup for a paid curriculum/class". Can't believe that you offer this for free to the world. You're doing an important service to space and science education and should be proud of what you've accomplished. Well done, sir.
I'm an aircraft engineer and I've learnt so much from you about rockets. You're like an old fashioned engineering teacher who's not afraid to challenge students with depth information. Thanks, Tim!
I've been following you for years Tim. Since before Boca Chica, and even since before Starhopper took it's first hop. I'm consistently amazed by not only the understanding you've garnered regarding these incredibly complex topics, but the simplicity with which you explain them. I've always loved space and spaceflight, but you were the catalyst for much of my understanding of its nuance. For that, I cannot thank you enough.
Hey Tim, i doubt you will see this as this video is now 2 years old but as a 19 year old aspiring aerospace engineer i just wanted to say what you do for the community is amazing and it is very clear how much you care about not only the content you produce but how the audience sees it, every video of yours that i have watched has helped loads and is super clear to understand and im exited for the endless hours of content of yours that i am still yet to watch, so from me and the entire community THANK YOU TIM! legend.
Can you make a video about the structural engineering of rockets? I am always amazed how they transmit hundreds or even thousands of tons of thrust into the chassis, without everything just getting crushed^^
The way they manage to do that is basically just pressure. Just like how you can stand on a closed full soda can without a problem but when it's empty and doesn't have pressure inside it will crumble under the load. If you have a thin wall tube that you put under a load it will want to move and deform. But if you cap it off and put some pressure into it, the pressure inside will will push against the tube walls and spread out the load across the whole thing and actively fight against it changing shape since that would require the gass to compress even further. I't like how the more you blow up a balloon the harder the outside of the balloon feels.
Yes, I have asked for this topic before. The mechanical engineering doesn't get nearly as much attention as the chemistry. All that expanding gas pushing on the diverging surfaces of the nozzle, and the injector plate, and then up through the... um, how does it all not blow itself apart and crush itself? The entire weight of the vehicle balancing on the tiny surfaces of the thrust bearings! The mechanical engineering is insane.
It's all about the choosing the right shapes (and materials too) , for example a cylinder is very strong for axial forces, and a nozzle bell have the same shape and strength as a cathedral dome.
I like how you took us from a simple party balloon to Raptor 2 engine. Thank you very much. No lecture would be able to understand those basic concepts as fast as you did.
Hey Tim, recently my team and I placed top 3 in a national aerospace highschool competition called StellarXplorers. I think it’s partly because of you that we succeeded with your immensely informational content. Keep up the great work! :)
I LOVE how this video works from the bottom up - from just opening a valve, where the recoil pushes back (which everybody knows and understands) to what if you do X Y and/or Z to improve. This is literally how engine development advanced, so it makes sense to teach it this way.
The production quality on this channel is amazing! I think one day we will have variable expansion ratio combustion chambers and this will solve many issues like throttle ability, although of course, it’s anyone’s guess how material science and technology will evolve. Nevertheless this channel always sparks my creative mind and I appreciate the content.
This is the first video which really gave me an intuitive feel for how the different cycles work, rather than just kinda understanding it academically. Really awesome.
16:00 There were some other (never flown) rocket designs that planned to reach orbit with just pressure-fed engines, like the German company OTRAG's design of a cluster of a huge number of mass-produced cheap rocket modules, and the Sea Dragon that planned to get past the mass ratio issues of being pressure fed with simple brute force of being absolutely huge.
Amazing, definitely your best video to date! Can't believe it was almost an hour. Thanks to all people involved in producing and reviewing the content for the hard work that made it so easy to watch, understand and enoy!
I know we don't get videos quite as often these days, but it's pretty obvious why. This is clearly years of research and knowledge condensed into less than an hour and I just want to say thank you for that. Thank you too your editors for the excellent animations and graphics. And although I'm not a channel member, I want to say thank you to everybody that can support you monetarily. Tim you're an absolute legend.
This is my new favorite video! The level of detail was exactly what I was looking for to understand the different engine types, and the graphics were amazing at helping visualize it all. Thanks for the incredible work!
Another amazing educational and fascinating video. The graphics are superb and really help simplify and visualize these extremely complex engine systems. Thanks Tim.
Tim, just imagine if Elon sent you up to the ISS on an Axiom mission with a film crew. Picture the sense of adventure you would bring to all of us sitting in our living rooms throughout the entire training and mission, every nuance and appreciation of the experience highlighted which others might have just taken for granted. Elon's over-arching goal of making people be excited to get up in the morning needs to be transmitted to the masses. It's not enough to achieve it, it needs to be documented as it unfolds. More so than just a standard biography, Elon needs someone to document the sheer breathtaking experience of how he has already brought our optimistic science fiction future into today's reality. Noone would do it better than you. I've been following your work since the start, so much so that you have made me a fan of all things Space. Your videos are always engaging, and the progress you've made over the years in quality is excellent - the epitome of Elon's iterative design philosophy. Your success in outreach has brought the dream of space travel to all the little would-be engineers and scientists the world over.
@@Enxuvjeshxuf well now Tim is actually going to the moon so its even better than going to the ISS and not really fan fiction anymore. hes been chosen as one of the crew members for the DearMoon mission which is going to orbit the moon and is launching in the end of next year 2023
Absolutely magnificent! I thought I already had a pretty good idea of cycle types, but still learned a lot. Each time a question arose in my head, you did immediately address it in the next sentence or so.
Loving all these videos about how to get into space but would love to see some in-depth vids on once you are in space. Things like getting rid of excess heat, potential ways of artificial gravity, power sources for long durations, water/waste recycling, exercising, etc. Thanks.
I really liked how the equations were presented around 39:00. Including the variables in one color and their definitions immediately to the right in small text. Genius! I might start doing that whenever the situation calls.
Quite seriously - I have no idea how you do these videos. They are by far the easiest to understand and most information packed videos I watch. Hats off to you dude
wow. just wow. As an aerospace student I can attest to the succinctness and grace through which you've distilled weeks worth of my laboring over textbooks into a single, engaging, digestible, hour. I recently had an art history major friend school me on soviet rocket history.. ART HISTORY MAJOR. You truly are bringing space down to earth for everyday people. Thanks Tim, your impact will be profound.
1 minute out, and already 49 comments. Wow Tim, You've come a long way. And we've been here for the ride from the beginning. Thank you for leading us all on this wild journey!
Again, the inspiration to continue my studies brought upon by this amazing channel is greatly appreciated! Thanks Tim and the team that made this video possible! 10/10
Tim I love the way you present mathematical equations. Most people just show the letters/symbols representing each term and tell you what it represents once, it's so helpful how every time you show the equation the labels are always there as a reminder. And your graphic design for it is so elegant. Great work as always!
Fantastic video, Tim! I agree, it's your best video in terms of clarity and animations. I am able to follow it on 2x, which means it's incredibly well made. Congratulations! Now, I think we're all waiting for the "How to start a rocket" video :)
Tim thank you so much for putting up that animated diagram of the ox-rich turbopump at @29:04 instead of just the basic diagram like in your raptor engine video... it really helped me to understand it further.
Great graphics as always Tim! I particularly enjoyed the review of the simple (pressure fed) and really exotic engines (expander and tap off). And now I am really really looking forward to the episode on starting a rocket engine!
OMG! Thank you Tim! Again one these very well done videos. And you still increased quality. Amazing, loved watching. I’m just sorry I can only 👍 it once. Looking forward to the next. Maybe electric engines like VSIMR or Hall thrusters.
Outstanding work as always Tim! I definitely had to rewind quite a few times so that my small brain could absorb what you were saying but you really did make it understandable!
Thank you for this video I've been lost in the last couple of days looking for how rocket engines are fed fuel and this really made it clear, i can't wait to know how rocket engines are started.
Such a great video, as always of course! I love the way you start with the simplest cycle types instead of the complex ones, it really helps me understand and grasp why these engines are designed the way that they are, and why all that complexity is necessary. I also like how you discuss WHY some cycles are used instead of others: it is often overlooked in videos explaining specific cycles.
Hey Tim, thanks for taking the time to make this video. Absolutely brilliant and great follow on from the Russian engine video. Keep up the great work of bringing space exploration down to a level we can all understand. I have learnt loads which in turn has upped my interest in rockets. Greetings from the UK.
@@EverydayAstronaut I'm not surprised to hear that - everything you do is brilliant and inspiring and I will love watching your next videos regardless!
Tim, you have done it again. You have paid it forward so well that it really shows I am able to understand so much better after you given your explanations, than anyone else that does deep dives on space.. I always come away not only with a greater understanding of the subject, but with also a greater respect for what and how you do it. Hats off to you!
This is such an awesome video Tim! Really appreciate all the efforts that you and your team put into this video, you're definitely bringing space down to earth for everyday people! Btw, I would love to watch an everyday astronaut video comparing JWST and Hubble.
The year is 2067, the first warp engines are being tested in humanities pursuit to other stars, and Tim Dodd explains exactly how it works as simply as 2+2
I’ve been a Florida resident for 20 plus years but had never been to the visitor center, went yesterday! and this video is the perfect thing to watch after! Your the best dude!
Awesome, thanks for the incredibly well explained and well presented lesson on how rocket engines work, I will have to watch this several times to cement in some of the concepts :)
Thank you so much Tim for bringing us these moments! History in the making and I super appreciate your intense understanding with Elon. Amazing work, please keep it up! 👏
Wow, i finally understood the different cycle types. And it gets a bit more obvious why the Raptor Engine is supposed to be so robust and maintenance-easy with the preburners running so cool.
As an engineer with only a passing interest on space technology, I'd seen one of your videos before, and thought 'wow this guy is well connected - he gets a personal tour of Space X with Elon Musk'. Having fallen asleep with UA-cam on auto play, and woken up with this playing, it's very easy to see why. That was probably the best example of how to present a very complex subject to a largely non specialist audience I've ever seen. Exceptional work!
Honestly, I really just like hearing you talk and explain things. Your pacing is really good, your accent is pleasant and your content is compact and concise while not being devoid of your own opinions or anecdotes that are interesting. Thanks for the great work Tim!
Wonderful explanations of complex concepts. The fact that you can make this topic digestible in the way you have fully demonstrates that your tagline of "bringing space down to earth for everyday people" isn't just lip-service. Thanks so much for doing what you do!
@EverydayAstronaut you didn't specify which orbit. Lunar Module Ascent Engine was pressure fed and it got Ascent Module on lunar orbit. It even managed it as a single stage to orbit.
Rocket engines are the coolest thing ever. At 45 years old I still get giddy at close up shot of rocket engines doing there thing. They truly are amazing things.
I've always had one gripe with your videos explaining rocket engines: FLUIDS FLOW from regions of high pressure to low pressure. PRESSURE DOES NOT FLOW, it is not a thing, it is a quantity. It doesn't really change the conclusions, but it can be confusing for a lay person. Incredible video otherwise!
How excellently Elonmusk explains each and evey parts of rocket 🚀. This shows how passionate he is about going to mars although he doesn't even have a space degree this makes me believe I can do anything no matters about degrees. Perfect
Tim, your dedication is making many of your viewers amateur “rocket scientists”. I am old enough to have witnessed fhe space race since the beggining as a teenager, and been fortunate to have built a considerable first-class technical library on the subject. But I never stop being surprised to having learned something in all of your videos. Keep it up, there is more to learn.
Tim, you are one of a half a dozen youtubers whose content has not gone down the drain. You are still on top of the game. Thank you for making everybody more of an astronauts.
These videos are absolutely phenomenal. I provide aerospace education to cadets in Civil Air Patrol. The Everyday Astronaut is my number one source for rocketry topics. Well done and thank you, Sir!
wow, finished a 1 hr video in 2 hrs!! but boy do you learn a lot!!! This can easily be a Netflix special for geeks or on discovery +.I can only imagine the amount of research this needs!!
How have less than 10% of the people that watches this video given it a thumbs up? I suck at UA-cam so I don't know how to properly tag this. Dark Warrior said it best "I learned more about rocket science in the last 30 minutes than I have in 5 years, wow dude. You are good at teaching this."
Thanks Tim! It’s amazing how well you explain a complex engineering problem for regular people! You should consider creating a print with the schematics of each type of engine! I would love to put that in my office next to my Soviet rocket schematic print.
Thanks, Tim. You've cleared up some questions that I had floating around in my mind, though you've also opened some new "tracks" for my "train of thoughts" to pursue. As always, you are clear in your explanations and the animations really help as well.
I get it, I finally get it. I read the article instead but dropping a comment here (and like) for YT algorithmic goodness. Very well explained, looking forward to see what the engineers at the bleeding edge can pull out to squeeze out even more benefits from an engine. Materials science seems to be a cornerstone to how innovative and previously unfeasible engines become reality; the future is looking bright!
You know what Tim, I would rather listen to you any day that a self-important person like Neil Tyson. You admit to being human and that you might struggle to understand certain complex subjects. I am so glad you put yourself out there and bridge the gap between people and giant things like NASA, Space X, and Rocket Technology. You are greatly appreciated, Sir!
Masterclass in breaking down a complicated topic. Great job to you and your team!

Exactly!
I totally agree!👍
Thanks to Professor Tim and team.👍
This is only one part of it: staging, orbital mechanics...
Rocket science is really simple, throw hot stuff out really fast in one direction and go the other. Rocket ENGINEERING however, now thats complex!

I am able to understand so much better after you given your explanations, than anyone else that does deep dives on space..
I always come away not only with a greater understanding of the subject, but with also a greater respect for what and how you do it.
Hats off to you!
I saw 55 minutes and I thought this is too long but here I am smiling as I've learned something new about rockets. Thank you, Tim!
This is such an awesome video Tim! Really appreciate all the efforts that you and your team put into this video, you're definitely bringing space down to earth for everyday people! Btw, I would love to watch an everyday astronaut video comparing JWST and Hubble.
The year is 2067, the first warp engines are being tested in humanities pursuit to other stars, and Tim Dodd explains exactly how it works as simply as 2+2
_how to program a warp engine with 3 lines of python_
And in 2026 how the fuel cell powered cryogenic superconducting combined radial and axial flux electric motor fed rocket engines work.
Or why it won't work.
But first comes: "Why spin-launch won't work."
❤️ Tim you are like most useful and entertaining civil servant considering how much knowledge you spread for free! You are the best
My kids (9 and 11) loved this. We had a great time pausing and talking it through.
I’ve been a Florida resident for 20 plus years but had never been to the visitor center, went yesterday! and this video is the perfect thing to watch after! Your the best dude!
This was fantastic - thanks! I learned a ton. So well done! Can’t wait for more! Q: How is the Raptor2 an improvement over version1?
It's got a lot fewer sensors and bolted flanges.
In addition to the previous comment, it also has more thrust and is simpler to manufacture!
Awesome, thanks for the incredibly well explained and well presented lesson on how rocket engines work, I will have to watch this several times to cement in some of the concepts :)
Thank you so much Tim for bringing us these moments! History in the making and I super appreciate your intense understanding with Elon. Amazing work, please keep it up! 👏
Wow, i finally understood the different cycle types.
And it gets a bit more obvious why the Raptor Engine is supposed to be so robust and maintenance-easy with the preburners running so cool.
As an engineer with only a passing interest on space technology, I'd seen one of your videos before, and thought 'wow this guy is well connected - he gets a personal tour of Space X with Elon Musk'. Having fallen asleep with UA-cam on auto play, and woken up with this playing, it's very easy to see why. That was probably the best example of how to present a very complex subject to a largely non specialist audience I've ever seen. Exceptional work!
Was soo excited. But still can't wait for the whole starbase interview.
Thank you for the great work!!!
Your Videos are always so cool to watch, you dont notice the hour going by, because it is all so interesting. Can't wait for the Full Elon Interview!
This is great content for the space & rocket nerd in me for years now... and still counting. Keep up the good work 👏 👍 @ Tim
Honestly, I really just like hearing you talk and explain things. Your pacing is really good, your accent is pleasant and your content is compact and concise while not being devoid of your own opinions or anecdotes that are interesting. Thanks for the great work Tim!
Wonderful explanations of complex concepts. The fact that you can make this topic digestible in the way you have fully demonstrates that your tagline of "bringing space down to earth for everyday people" isn't just lip-service. Thanks so much for doing what you do!
I can't believe I didn't have to pay for this.
This was incredibly well explained!! Thank you!
@EverydayAstronaut you didn't specify which orbit. Lunar Module Ascent Engine was pressure fed and it got Ascent Module on lunar orbit. It even managed it as a single stage to orbit.
Rocket engines are the coolest thing ever. At 45 years old I still get giddy at close up shot of rocket engines doing there thing. They truly are amazing things.
I wanted to refresh my memory on cycle types and watched this video. I think this is the best explanation I've ever seen!
23:35 not a big mistake, but sadly the "°C" is missing at the temperature of the Combustion chamber
Otherwise a very awesome Video tho.
I've always had one gripe with your videos explaining rocket engines:
FLUIDS FLOW from regions of high pressure to low pressure. PRESSURE DOES NOT FLOW, it is not a thing, it is a quantity.
It doesn't really change the conclusions, but it can be confusing for a lay person. Incredible video otherwise!
I cringed each time he said that.
How excellently Elonmusk explains each and evey parts of rocket 🚀. This shows how passionate he is about going to mars although he doesn't even have a space degree this makes me believe I can do anything no matters about degrees. Perfect
Tim, your dedication is making many of your viewers amateur “rocket scientists”. I am old enough to have witnessed fhe space race since the beggining as a teenager, and been fortunate to have built a considerable first-class technical library on the subject. But I never stop being surprised to having learned something in all of your videos. Keep it up, there is more to learn.
Tim, you are one of a half a dozen youtubers whose content has not gone down the drain. You are still on top of the game. Thank you for making everybody more of an astronauts.
Great show tim, but remember how far/quickly things have progressed, and "nothing" is impossible!
Well done, but this shows how advanced those Rusky engineers and scientists were!
I have a headache
same
It's just rocket science
Me too

I’ve watched this video a few times and I am still in awe of how well done it was. Thank you for putting this out into the world.
Coming back to this after a year. We definately need a video about the exotics, like SRB's, xenon/ion and nuclear
These videos are absolutely phenomenal. I provide aerospace education to cadets in Civil Air Patrol. The Everyday Astronaut is my number one source for rocketry topics. Well done and thank you, Sir!
This channel is honestly the most valuable thing in the entire internet
wow, finished a 1 hr video in 2 hrs!! but boy do you learn a lot!!! This can easily be a Netflix special for geeks or on discovery +.I can only imagine the amount of research this needs!!
How have less than 10% of the people that watches this video given it a thumbs up? I suck at UA-cam so I don't know how to properly tag this. Dark Warrior said it best "I learned more about rocket science in the last 30 minutes than I have in 5 years, wow dude. You are good at teaching this."
Thanks Tim! It’s amazing how well you explain a complex engineering problem for regular people! You should consider creating a print with the schematics of each type of engine! I would love to put that in my office next to my Soviet rocket schematic print.
Videos like this are why I think video sharing like UA-cam is one of the greatest gifts of the internet age. Thank you.
Thanks, Tim. You've cleared up some questions that I had floating around in my mind, though you've also opened some new "tracks" for my "train of thoughts" to pursue. As always, you are clear in your explanations and the animations really help as well.
I get it, I finally get it. I read the article instead but dropping a comment here (and like) for YT algorithmic goodness.
Very well explained, looking forward to see what the engineers at the bleeding edge can pull out to squeeze out even more benefits from an engine. Materials science seems to be a cornerstone to how innovative and previously unfeasible engines become reality; the future is looking bright!
Took me 2 days to finish the video and understand everything well. We really appreciate you Tim making these videos for all! thanks!
I love this stuff. Engineering an engine is much like solving a logic puzzle, but one with many variables. It's both elegant and complex.
You know what Tim, I would rather listen to you any day that a self-important person like Neil Tyson. You admit to being human and that you might struggle to understand certain complex subjects. I am so glad you put yourself out there and bridge the gap between people and giant things like NASA, Space X, and Rocket Technology. You are greatly appreciated, Sir!
