  • at least russian engines work good for others. russia itself cant launch anything anymore.

  • USA never went to the moon! Anyone thinking otherwise is.....SILLY

  • @StreetArtillery Proof?

  • @yugozastava13 You want proof? Here goes. Russia says that to this day, we don´t have the technology to get there. That´s why they haven´t sent their cosmonauts to the moon. It was all staged by Hollywood´s best. Besides religion, the moonlanding is the greatest lie ever.

  • RD 170

  • The real hope the US has at affordable flight right now is Falcon9. If spaceX can work out all the bugs, it should be half the price of Atlas V and man rated. 

  • This is probably the best rocket the US has (at this point in time) which is not saying much. Success is maily due to the Russian RD180 engine. The cost is double what it could be mainly because anything with the "Lockheed" name is expensive. In addition, stacking the rocket (rather than assembling horizontal) always costs more. Lockheed had a winner with Titan II. If they had upgraded the second stage it would have been right there with Soyuz on the price points.

  • 2) Specific impulse

    Specific impulse is important because it determines propellant efficiency once in space. With low specific impulse, you must carry an excessively large amount of fuel to accelerate the vehicle to orbital velocity.

    If you're willing to wait, a low-thrust, high-Isp engine is best for interplanetary travel. It will get you there slowly, but it won't use much fuel.

    For getting out of the atmosphere, high thrust is still critically important, regardless of Isp.

  • Allow me to set the record straight. Both thrust and specific impulse are important.

    1) Thrust

    The rocket must have more thrust than its initial weight, or it will just sit on the pad until it has lost enough propellant for its thrust to exceed its weight. That's really awful for overall propellant efficiency. It's much better to give the rocket thrust well in excess of its weight (greater by 30 to 50 percent).

  • I love nerd word fights.

  • hehe best team but engine from rusia.

  • Russian engine !! both countries the usa and the soviet union including russia have the pioneers!!

  • nope, the pioneer was only one, Konstantin Tsiolkovsky.

  • After this visit the U.S bought 101 RD 180 rocket engines. The Russian builder NPO Energomash

    and Pratt& Wittney are in a joint venture building derivatives from this RD 180 engine.

  • @frankyspeaker

    there is nothing special about the rd 180, you have no idea what you're talking about. in fact it were the russians who had problems catching up to american engine know-how. the russians never managed to build an engine as large as the f1 (saturn v first stage engine)

  • @gucker07

    These engines are very special!! The US FAILED at building these type of engines for over 2 decades and they gave up on it!!

    And you say there is nothing special about these engines?? Please!! You either HATE Russia or you are just too proud that not everything USA is better!! But i think it's both!!

    Must be really painful for you to DEAL with this FACT!! Go stick you head in the sand lol!!

  • @gucker07

    Remember that being too proud can blind people and makes them unobjective like in your case! Thanks for the laugh lol!!

  • @frankyspeaker

    lol, i'm german. and maybe you can tell me what's so special about those engines? lol

    they're standard lox/kerosene first stage engines. the 180 is a good, reliable engine, nothing more, nothing less.

    oh, and maybe you can tell me why russia has never managed to build an engine the size of the f1 or one as efficient as the ssme. but you can't cause you don't know what you're talking about, lol

  • @gucker07

    A German who writes proper English??

    I doubt that very much lol!! Would be a first on YT!! Having Germany on your profle doesn't mean you are from Germany lol! Now get your head back in the soil. Standard los/kerosine engine?? Hahahaha. It's not a standard engine lol!!

  • @frankyspeaker

    lol, want me to speak german to prove it? and you still haven't answered me what's so special about this engine, lol. and you haven't addressed the f1/ssme (bet you don't even know what that stands for). what a fool you are.

  • @gucker07

    Wether you are German or American you are a fool lol! And why should i have to talk about another engine when it's about the RD-180?

    Is it bragging from your side??

    We talk RD-180 here and you are in denial because the RD-180 doesn't work in the same way as you "seem" to think lol!!

    That makes you ignorant! The US failed to build "this kind" of engines for over 2

    decades lol!! And i do know where it stands for.

    For HISTORY and SOON HISTORY!! LOL!!

  • @frankyspeaker

    it's so obvious you don't know yourself what's so 'special' about the rd 180. let me tell you: nothing.

    prove me wrong (you can't). lol

  • @gucker07

    Stop making yourself look like total idiot in full denial lol! Do you think i would have posted what i posted about this type of engine if i didn't know what type of engine it is and what the difference is?? LOL!!!

  • @frankyspeaker

    yes, i think you don't know anything about this. you still haven't explained what makes this engine 'special' because you can't. you're a real sucker.

  • @gucker07

    What an ass you are lol!

    Can't you read or get a obvious thing i posted?

    You should call me a sucker in my face!

  • @frankyspeaker

    answer the question or shut up. moron.

  • @gucker07

    Even if i would tell you the difference you would still deny it lol! You should already know the difference between the working of the RD-180 compared to US engines because

    it's common knowledge!

    I know this for decades already dipshit!

    That's why i posted what i posted!

    Because i know!

    Small hint again. Both use kerosene/lox

    but RD-180 pre burner is Lox rich and US engines pre burner are kerosene rich.

    What does this difference bring??

    Please tell me!

  • @frankyspeaker

    no, you tell me. and keep reading those wikipedia articles, lol

  • @gucker07

    Wikipedia articles?? HAHAHAHA!!!!

    What a fool you are and what a arrogance you have lol!! Totally mIsplaced arrogance that is of course. Like i said it's common fact that

    the RD-180 works diffently than the US engines. The Russians cracked it and the US totally failed at it because they couldn't relief the higher pressure from the lox rich pre burner. Now you know a little more again lol!

  • @gucker07

    The fact that you even have to ask me what the difference is makes you totally ignorant! Where have you been all these decades lol? O yes, you were stuck with your head in the soil!! HAHAHAHAHA!!!

  • @frankyspeaker

    lol, maybe you should get some basic knowledge on engine development first, then we can talk. you don't even know the ssme or f1 yet expect to be taken seriously? the rd 180 doesn't hold a candle to either one of them, lol

  • @gucker07

    You really can't read lol!

    I already told you that i know the F1and SSME!!

    F1 is engine from Saturn V and SSME engine from Space Shuttle! Like i said HISTORY and SOON HISTORY!!! You really are not the smartest lol because that should be enough for any smart person to know what i meant with HISTORY and SOON HISTORY!!

    LIke i said you are ONLY biased!!!

    Wich makes you UNobjective!!

  • If you really knew what you are talking about you would know that both the f1 and the ssme represent far greater engineering achievements than the rd 180. again, what a fool you are...

  • @gucker07

    No lol!! You are a fool and you have proven that time and time again. The fact that you constantly bring up other stuff is a clear sign that you are!! We were talking about the RD-180 working in a different way!!

    So stick with that instead of showing constantly how biased you really are!!

  • actually we're talking about who is ahead in engine technology. answer: the us. the ssme and f1 are proof of that. just shut up and stop embarrassing yourself...

    and again: there is nothing special about the rd180 at all. look at the specs.

  • @gucker07

    What a hilarious idiot you are lol!!

    Read carefully: The FACT that the US tried to build the same type of engines as the RD series is PROOF that the RD type engines are better!! They are more efficient and have better TTWR!! It's really that simple lol!!!

    You think the US would spend millions for nothing?? BIASED FOOL!!! HAHAHAHAHA

  • you are the idiot. the rd is much less efficient than the ssme (the relevant measure for that is the specific impulse) and is also a much lower thrust engine than the f1. once again you demonstrate your complete ignorance on this subject.

    btw: the us has developed the delta iv which has the same performance as the atlas v and which has no russian built engines.

    the only one biased here is you, i'm just stating the facts (of which you're clearly ignorant).

  • @gucker07

    Again. What a fool you are!!

    I know the F1 has more power but NOT a better Thrust to Weight Ratio!!!!

  • @gucker07

    AGAIN:

    The FACT that the US tried to build these different working engines is what PROVES how good and effective they are because if this was not the case the US would not have tried to build them!!! What is so difficult for you to understand this logical fact??

    O yes your biasedness!! Nothing else!!

    Guess where the expertise and the design of the engine lay out of the F-35 STOVL comes from?? LOL!!!!

  • do you even know what specific impulse means? i was referring to the ssme here. fool.

    and like i said, the delta iv has american made engines and the rocket has the same performance. do your homework. you have proven nothing. all you do is put out more bullshit with each post.

  • @gucker07

    How dumb are you really??

    I posted a fact about the RD-180 working differently than the US engines and you are in denial about that wich makes you wrong!!! PERIOD!! And it doesn't matter wich US engine lol!! RD type engines have the best TTWR compared to ALL US engines!!!!

    And that's why the US TRIED to build them but utterly FAILED at it!! That's more FACT!!

    DEAL WITH THAT BIASED IDIOT!!!

  • @gucker07

    And STOP bringing up other stuff like you did before because it has NOTHING to do with what i posted and what you WRONGFULLY denied!!

    The fact that you constantly bring things up only proves you're wrong and in denial!!

  • @frankyspeaker

    ofc these issues are relevant here. address them or shut up. you're the one who is biased and who can't deal with the fact that he is simply wrong.

  • @gucker07

    Not relevant at all!! The ONLY thing relevant here is the fact that the RD type engines work in a different way! More efficient, better TTWR!

    Just acknowledge the FACT that you are wrong with DENYING that the RD type

    engines work in a different way!

    Because they do work in a different way!!

  • @gucker07

    And how can i be biased when i don't say ANYTHING wrong about the US engines and ONLY the TRUTH about the RD engines??

    LOL!!!

  • @gucker07

    Only you are biased here because you are in denial about a very obvious and well known fact!

    Any rocket engineer knows that the RD engines work in a different way!!

    So who are you to say they are not???

  • @frankyspeaker

    i said the engine is nothing special as it has much lower performance than the ssme. you're wrong.

  • gucker07,

    HAHAHAHAHA!!!!

    1 RD 180 has almost TWICE the power as the 1 SSME engine!!! LOL!!!! What a biased idiot you are lol!! Now get your head out of the soil

    and face FACTS! It's obvious you are clutching at straws for days already so give it up!

  • @frankyspeaker

    the isp is the relevant measure when it comes to efficieny. the ssme is the highest specific impulse engine ever built. fact, deal with it. you're a complete noob on this subjects, please stop embarrassing yourself.

  • gucker07,

    Keep with what we were talking about and what you denied! The RD 180 has a 10% better performance relative to it's weight than any US engine! It's called TTWR!! You still think the RD 180 doesn't work in a different way?? LOL!!

  • @frankyspeaker

    lol, wasn't it twice the power? lmao. also, isp and thrust are more relevant measures. face up to the facts and stfu already.

  • gucker07,

    Again you show how dumb you really are lol!

    The RD 180 is almost twice as powerful as the smme!! I said 10% better performance RELATIVE to it's weight!!!!!

    That's TTWR!!! And you don't even get that!! LOL!!!!!

  • @frankyspeaker

    you clearly have no idea whatsoever how rocket performance is measured (in other words how 'powerful' it is, lol). the most relevant is isp and the ssme is the highest specific impulse engine ever built. you're just a waste of time since you don't know the first thing about rocketry. do your homework and until then stfu.

  • gucker07,

    You are hilarious lol!! hahaha

    And you know it yourself!! You are and only biased because if the RD 180 engine was build by the US you would say that it works in a different way!! That's how transparent you are lol!!

  • gucker07,

    And the most relevant is THRUST!!!

    THRUST is the most important thing when it comes to power! The RD 180 will put more weight into space than a smme engine!!

    Why?? Because it has more THRUST!!

    Almost 2 MN more!!!! Idiot!!

  • @frankyspeaker

    like i said, you continue to demonstrate you ignorance on these matters. isp is the most relevant measure, it basically tells you how efficient the engine is in converting fuel into kinetic energy.

    and thrust? lol, the f1 is the engine with the highest thrust ever built. you are an ignorant fool.

  • gucker07,

    Thrust is the most relevant!! With ANY engine!!

    You think that the smme lifts more weight into space than the RD 180?? WRONG!!!

    And wrong again because the RD 170 is the highest thrust engine ever build!!!

    And you talk about ignorance?? HAHAHAHA!!!

    What an ass you are lol!!!!

    A biased ass that is!! USA boy!!

  • @frankyspeaker

    no, isp is more relevant since high thrust is no good with a low efficiency engine. if the isp is too low the rocket wouldn't even reach orbit since more than 90% of a rocket's weight at lift-off is fuel. once again you demonstrate that you don't have a clue what you're talking about. and i already told you i'm german, shithead.

    seriously, what a joke you are.

  • gucker07.

    The RD 180 isn't a low efficiency engine!!

    And the smme's higher isp doesn't overcome

    it's almost twice as low thrust!!!

    I know your German but still you are a USA boy!!

    You are biased wich became clear from your first post when you denied the FACT that the RD 180 works in a different way!!!

  • gucker07,

    You still think that the F1 is the highest thrust engine ever built????

    The FACT that you didn't even know that the RD 170 is the highest thrust engine ever build says everything about your ignorance and biasedness lol!! Now go to sleep because you have to get up early to go to the kindergarten!!

  • @frankyspeaker

    you are simply wrong. lol. arguing with a fool like you is a waste of my time. over and out, you're now blocked.

  • gucker07 ,

    THANKS!!! For proving how wrong you are lol!!

    First you post on my page and then you block me?? That says EVERYTHING about how wrong and childish you are!!! HAHAHAHAHA!!

    YOU LOST!! BIG TIME!! And your actions

    prove that very clearly!! I LOVE IT!!!

  • @gucker07

    I give you a small hint lol.

    When the US tried to develope this type of engine they exploded constantly!! The US could not fix that problem so they gave up on it.

    The Russians already had them working

    for decades lol!

  • The Atlas 3 and 5 use the Russian RD 180 engine in it's first stage. A type of engine the U.S tried to build for many decades but failed to do so and gave up on it. After a visit to Russian rocket engine factory in the mid 90's they found out that the Russians used these type of engines already in the 60's!!

  • @frankyspeake we hire Russians today so they dont have to work in north Korea, Iran, etc. its not because they are smart, its because we are smart. dont fuck with me i make the decisions ass wipe.

  • @datzfast Wake up, stupid American moron! Those times when the Russian space agency was underfunded by the government are gone long ago. USA buys these engines from Russia coz it can't produce itself such engines. Americans are not smart they are just arrogant stupid oil thirsty morons.

  • @GloomyGonzales Not smart? We don't buy Russian engines because we can't produce them ourselves, we buy them from Russia because Russian companies don't pay their employees as much as American companies do, therefore making the price-per-unit lower than an American produced engine. It's freshman economics.

    Also, the American space program always has been, and always will be lightyears ahead of the Russian program. Deal with it.

  • The Atlas is now our only non-shuttle launch system in America. The Titan, which used nasty and expensive hypergolic propellants is retired. A lot of people wonder why Titan wasn't selected to launch the Orion space capsule.

  • You seem to forget Delta,Pegasus, and Taurus.

  • Comment removed

  • I have to get me one of thoes!!

  • Good Video

  • Atlas V rules! I celebrate the entire Atlas family, thanks for posting the video!
