Not only was this education, this was so entertaining! The “go boom” was killing me
I am glad u liked it
As an aerospace engineer, I love your work. Keep it up!
Thanks man I will do my best
Fantastic overview of all the problems, challenges, failures. What needs to be done and why / why not.
Glad U liked it
Dude i love your energy and knowledge! Thank you. Also Pro tip, watch video at .75x speed.
Thanks for the tip!
@@s2tenglishtip for viewers i mean. You keep doing you man! 🤟🏾 We await your next video!
The video would be much better if he wasn’t t on crack:)
1.75X speed, got it
I love the work you do! Explains a lot.
Glad you enjoy it!
Wow this presentation was probably the best I’ve ever seen on wrapping my head around rocket engines in general. I would take his lecture any day. Also if you did another video with more in depth technicals I’d be greatly interested! Thank you for this great content please keep it up 👍
Wow, thank you! I have made more video on the topic U may like this one , th-cam.com/video/7o0CMMaLzGk/w-d-xo.html , Raptor Engine Explained
Love it! Could you do another video on turbo bumps explaining a bit deeper in to it?
I could try
I know this isn't your most recent video but i love it!
hey as long as it works 😜
Awesome video! Thanks!
Thankyou
I love the thumbnails you put
Thanks
Mate I agree with the last comment two years ago. I love your style and your energy!!! It's so clear that You love this stuff
I appreciate that!
@@s2tenglish no problem at all!! Now I'm working my way through your other videos!!!
"this puppy" and "bonkers" lol. learnt heaps cheers!
Enjoy
Fantastic overview!
Happy to help
Thank you for this video!
Happy to help
Great video !
Thank you 🙏
Enjoy
Great presentation. Thank you. You've got a new subscriber.
Awesome, thank you!
This was great. Love your enthusiasm for this
I am glad you liked it
@@s2tenglish hey do you know any 3D modeling programs for designing pumps. I'm just getting into all this, and was wondering where I should start?
Any help would be appreciated 🙏
@@JohnDoe-ef3wo start with Onshape or fusion 360
@@s2tenglish I'll look into those. Thanks man..
very informative thanks
Glad it was helpful!
Phenomenal! Thank you.
Enjoy
Love it!
Thanks
Best video on rocket
Glad U liked it
Well done. I want more.
well there is 194 video in this playlist alone and other topics which is in 776 videos so U should find something U like
Man, so educational. So much information. Thank you! One suggestion I have, that is the same for most non-native english speakers, is just try to slow down as much as possible and pronounce your words as clear as possible.
I will do my best
Fantastic video.
Glad you enjoyed it
interesting !!!! thank you 👍
Thank you too!
Also, in open cycle engine only, we call combustion for turbopump as a gas generator,
in closed cycle/full flow, it's called stage combustion (pre-combustion) as the main job there is to make the prop / LOX into gas, and a by-product of it is running the turbines.
About the pump, the role of metallurgy is demonstrated well in the RD-180 well (OX Rich), and RS-25 is a workaround to get a closed cycle.
True
Good video. Do you have any videos on the plumbing of a turbo pump, specifically in an evaporator cycle? Can't find much on it outside of info on nozzles.
evaporator cycle? example please
@@s2tenglish *expander cycle my bad
I believe Blue Origin's lunar lander engine will be an expander cycle, it's called the BE-7
oomph puppy go boom
BOOOM
I love this damn guy...
Glad to hear it
I happened to see the video now.. as told in video .. there are lot of errors..
"Fuel and Oxygen mixture quantity should be same.."he took example of methane as fuel..
but its wrong.. LOX has density equal to RP1 .. noth Methane..
what LOX has equal to Methane is thermal properties, boiling point , which makes tank design easy..
can you please provide the numbers so I can pin it here I made a mistake
Hi there, you have enormous amount of knowledge in this field. please try to work on presentation skills .people like you are an asset for society. You should be celebrated. Some points that i can point out are, explaining in simpler languages and speaker a bit slower. Thanks for sharing you knowledge.
I will try my best
A very detailed explanation of why rockets are the way they are. But one question about Rutherford engines, why battery pumped rocket engines can't be scalable? Is it just weight of battery or economics or any other engineering challenge??
RS25 engine needs about 23,260 hp just for Oxidizer system & 71,140 hp for Fuel system so total 70 + MW there is not battery system on earth that can provide that kind of power for even 10 s let alone what u need for a actual launch
I seriously thought that the amount of information coming from this guy was amazing. His ability to convey it to where a bonehead like myself can understand it was phenomenal. I understand he is putting as much info aa he can physically speak out and still be clear. But I can not help but to think that either my brain is incredibly slow or his ability to speak was lightspeed.
I do talk fast sorry
I have exam tomorrow and I am watching this... I'm a food technologist 🤷♂️
Good LUCK
why the subtitles are not available :(
I am sorry but i can't afford it
❤❤❤❤❤❤❤❤
👍
I understand the difficulties of making a turbopump but...
but there are hundreds of companies in India making pumps
so lets say someone calls them and say "hi, I want to pump 50 kilos of LOX per second"
he wont find a 3-4 of companies accepting the challenge ?
What do you think ?
I havent tried it yet
but i have the feeling that he would find someone
50 kilos of LOX is wrong unit u need liters per min & themperature is an another issue + how will U drive it while making everything as light as possible
@@s2tenglish A) i m sorry, i m not an expert but RPA says:
Oxidizer mass flow rate: 53.04132 kg/s
B) I didn't say i will design a pump
What i said is that there are several pump calculators even online
so what you want "in" and what you want "out" can be calculated easily
Right ?
So given the fact there are so many companies in India making pumps already
water pumps ?
oxygen pumps ?
gasoline pumps ?
But at least they have experience with pumps
So if you tell them "i want a pump with THESE specifications" will they all deny to develop a pump like the one you want ?
i m not saying that it will be cheap or expensive or i dont know
I m asking if any company there will say "ok i ll give it a try"
@@s2tenglish Mind you, i m not saying your video is wrong
I agree in everything you said
Making a pump is probably the toughest part of all
Thats why Rocket Labs dropped the idea of making a turbopump and created an electric pump
And its not just them
Many small rockets do so because (i guess) to make a turbo pump for a 10, 20 or 30 kN engine is rather too expensive and too bulky and heavy and complicated
Yes you have the battery weight but still an electric motor is much simpler than a turbine
There are already 2-3 companies in Europe making electric pumps for smaller rocket engines
Now if you go above 50 or 60 kN then the turbopump is one-way road
Unless someone comes up with something new (or old and revised)
He's swallowed a turbo pump 😀
LOL
Talk slower, other then that I'm a fan, you rock man
Never mind talk as fast as you want you love what your talking about.
thanks
I tried to follow but I just can't translate his dialect to USA English. Plus, his pace is so fast to make it impossible. I tried.
you can slow down the video to your liking
Elon musk was here circa 2002
???
Could you reduce the speed of your explanation,and increase the volume of your voice it would be great.It looks like you are in a hurry to go somewhere.
U can slow the video down to your liking
Pity, l think this would have been great if I could f@&$@! understand this man...
sorry
Speak clearer English!!!!
okay
I thought the english was very clear.
His English is fine. Your just hard at hearing.
