RD-170 rocket engine

NPO Energomash documentary on the RD-170 (in Russian). The RD-170 (РД-170, Ракетный Двигатель-170, Rocket Engine-170) is the world's most powerful liquid bipropellant rocket engine. It burns kerosene and LOX oxidizer in four combustion chambers supplied by a single turbo pump according to a staged combustion cycle. Designed and produced by NPO Energomash, it was originally used with the Energia launch vehicle.

The most powerful rocket engine ever built. I would like to have one. nice job USSR scientists.

Yep, this is not about politics. F-1 did it's job ok but RD-170 is much more powerful and efficient.

Here the essentials:

RD-170:

Thrust (SL) 7.550 MN, (Vac.) 7.887 MN

Isp (SL) 309 s, Isp (Vac.) 338 s

F-1

Thrust 6.77 MN

Isp (SL) 263 s, (I didn't find the Vac. info)

"most powerful" is somewhat arguable. The 4-chambered RD-170 is the most powerful liquid fueled engine ever developed, slightly besting the F-1 single chambered engine on the Saturn V S-IC. Both are dwarfed by large solid motors such as the RSRM, however.

It comes down to how you define "best" and "engine". No doubt, though, the RD-170 is some fine engineering. I'm more intrigued by the RD-701 design, though. I wish someone would fund further development of it.

Americans should be credited for solving instability problems in the F-1 engine and achieving high-thrust with a single combustion chamber. Russians should be credit for the use of a single turbo-pump high-thrust engine, as the turbo-pump is the engine. Also the RD-170 uses the complicated closed cycle and gives higher chamber pressure, whereas the F-1 uses the simple gas generator power open cycle turbo pump. So stop fighting both of you and sell your engines to ISRO.

@SkyyCaptainn that would be cool  :D

@roboticmehdi

Yeah RD 170 is the best in the world when it comes to large LOX/RP1 engines. For example If I were tasked to design a serious heavy lift rocket and use as much existing components as possible I would take best of both worlds. 5 - 7 RD170 on first stage assisted by several SRB's taken from shuttle and hydrogen fueled second stage powered by modified space shuttle main engines. That beast would have useful LEO payload in range of 300 - 400 metric tons.

@MightySaturn5 look my friend. i dont hate americans, i dont hate anyone. im saying facts that you just dont want to accept. soviets opened the gates to space, they made it first with thair own engineer with their own work and they have a great history in space technology. so please respect that. americans have great space technology also. they made great history by making it to the moon. i respect that. i expect you too to respect these facts and be more friendly here.

[roboticmehdi]

@SkyyCaptainn Im not comparing them. I just commented that rd-170 is the most powerful engine and i like it but the user mightysaturn5 here is doing everything to make soviets look like shit. I will not let that happen after all they opened the gates to space they made it first there. I dont say that i hate americans, i like their space technology and i also like soviet/russian space technology. PEACE

[MightySaturn5]

@roboticmehdi You're a retard kid kid, you obviously don't like Americans and must be some european trash that can't accept that ONLY the United States had the technology to send men to the moon and back.

Like I told your ignorant ass -try reading The Soviet space race with Apollo (Siddiqi), its far better to obtain your information from a well researched book then for me to remark how its impossible for you to understand anything due to excess cat fecies clogging your ears, nose and throat.

[SkyyCaptainn]

@roboticmehdi

Well, you can't directly compare american and russian rocketry because they had slightly differnt design phylosophy. Russians continued to perfect LOX/RP1 engines while americans went to LOX/LH2 and big solids for liftoff assist. They more or less abandoned large LOX/RP1 engine technology after Apollo.

@MightySaturn5 First of all, learn to push the reply button. I didnt receive any e-mails that you responded. If i havent entered this page just for fun i would never know that you responded. Second, whoever Korolev was doesnt matter, the important is that he was russian and he worked for his country and made it the leader in space. But as i said before, americans kissed nazi Von Brauns ass. You cannot change the facts my friend, no matter how hard you try.
