Thanks man I will do my best

1.75X speed, got it

Fantastic overview of all the problems, challenges, failures. What needs to be done and why / why not.

Enjoy

[@justinnunez4894]

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 👍

[@s2tenglish]

Wow, thank you! I have made more video on the topic U may like this one , kzbin.info/www/bejne/baCTdICDlrGtfc0 , Raptor Engine Explained

[@clydecronin2122]

Love it! Could you do another video on turbo bumps explaining a bit deeper in to it?

[@s2tenglish]

I could try

[@rules436]

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.

[@s2tenglish]

True

[@claytonsneider7373]

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.

[@s2tenglish]

I will do my best

[@rules436]

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..

[@s2tenglish]

can you please provide the numbers so I can pin it here I made a mistake

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.

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.

[@sridharpalla5612]

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??

[@s2tenglish]

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 love this damn guy...

[@s2tenglish]

Glad to hear it

[@SuperSilviaS15]

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.

[@s2tenglish]

I do talk fast sorry

[@nikohamil538]

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

[@s2tenglish]

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

[@nikohamil538]

@@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"

[@nikohamil538]

@@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)
