Nibb31 Posted May 14, 2012 Share Posted May 14, 2012 Beautiful engine!And once you have an RD-180, you\'ll be half way to having an RD-170 to make a Zenit And once you have a Zenit, you\'ll be half way to having an Energia Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 14, 2012 Share Posted May 14, 2012 what are these things you speak of. I could use pictures and details. is this Zenit thing a UR based core? as for these RD engines. when i made the rd-191 I had a good 90% of these engines done lol Link to comment Share on other sites More sharing options...
Kryten Posted May 14, 2012 Share Posted May 14, 2012 The Zenit launcher uses the RD-171 the RD-190 was based off in it\'s first stage, but is otherwise not closely related; it was based off of the Zenit boosters on Energiya, and is much larger than the URMs of Angara.

Nibb31 Posted May 14, 2012 Share Posted May 14, 2012 The RD-180 is a 2 chambered version of the RD-190. The RD-170 is the 4 chambered version (and the largest liquid engine ever built). The RD-170 (4 chambers) was first used in the Zenit booster (the 4 boosters on the Energia-Buran)After cancellation of Energia and the separation of Ukraine (where the Zenit is built), the Zenit booster became the Zenit 2 launcher (or Sea Launch) 1st stage.The 2nd stage of the Zenit-2 uses a single RD-120 (4 of which were used on the core stage of the Energia).The Angara project was launched mainly because Russia is reluctant to use a Ukrainian rocket for their military launches.

Guest Posted May 14, 2012 Share Posted May 14, 2012 Perhaps, in the distant future, you could make both Zenit and Energia, and maybe Polyus parts for KOSMOS station pack. That would require, what, two engines (half of one of them you already have), an interstage for the Zenit, A decoupler flange for Energia, a quad adapter engine adapter for it and a handful of fuel tanks. Polyus would be more complicated, but should be doable. Link to comment Share on other sites More sharing options...
Kryten Posted May 14, 2012 Share Posted May 14, 2012 The 2nd stage of the Zenit-2 uses a single RD-120 (4 of which were used on the core stage of the Energia).That\'s a common misconception; the one on Energiya was RD-0120, which was, rather confusingly, a completely unrelated engine about three times the size; so you\'d need at least three engines.

Guest Posted May 14, 2012 Share Posted May 14, 2012 Russians and their numbering system...Anyway, Energia and Zenit are related enough that it wouldn\'t be a huge leap for a pack including one to include the other. And with trims being added in 0.15, it\'s possible that Energia would be able to fly straight without any trickery. Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 lol rd-170 is hardly biggest engine ever made.... F-1 was more powerful per chamber. and M-1 was the all time largest engine ever made. Link to comment Share on other sites More sharing options...
Tiberion Posted May 15, 2012 Share Posted May 15, 2012 According to the spec sheets, M-1 and F-1 were virtually identical in terms of output (6.6 to 6.7 Meganewtons) while the RD-170 is closer to 7.5.I\'m as big a fan of giant single chamber beasts as the next guy, but the 170 family has proven to be a good one, still widely in use (even in the US) while the F-1 and M-1... are not. Though it would be awesome to see the F-1 fly on the SLS again ) Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 yes but in terms of power per chamber the F-1 beats it. M-1 was still largest. reguardless of power. you are combining a bunch of things to make rd-180 to be biggest. I was saying based off size (no power) and then power per chamber. I am well aware that the rd-170 is the most powerful currently. until merlin 2.... if only F-1a flew 33% more powerful than F-1 Link to comment Share on other sites More sharing options...
Kryten Posted May 15, 2012 Share Posted May 15, 2012 I am well aware that the rd-170 is the most powerful currently. until merlin 2....I thought Merlin 2 was a purely conceptual (read; PR) project? Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 I thought Merlin 2 was a purely conceptual (read; PR) project?Doesn\'t mean they arn\'t going to built it. I mean they recently just finished landing gear for the falcon first stage hahaha. Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 Welp. today I slapped this thing together. just using RD-191 parts it endded up being like 14000 polies. so I redid some tubes and the chambers in a lower res. and upped the res to the end of the chamber and got it to 8000. Tomorrow I will paint it. Link to comment Share on other sites More sharing options...
NovaSilisko Posted May 15, 2012 Share Posted May 15, 2012 Do you plan to use normal maps for parts when 0.15 is out, or continue using the high-res meshes themselves? Link to comment Share on other sites More sharing options...
CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 Do you plan to use normal maps for parts when 0.15 is out, or continue using the high-res meshes themselves?depends on the quality of the shader. Ina ll honesty the models are pretty devoid of detail. if I had normal maps i could add lots of it. all the polies are spent on making the pipes and structure. However i will certainly try and have less polies. but since my engines for angara should be removed shortly into the flight and not drawn anymore i hardly see why high poly count counts.

Kreuzung Posted May 15, 2012 Share Posted May 15, 2012 Because the most performance problems appear during launch. Link to comment Share on other sites More sharing options...

CardBoardBoxProcessor Posted May 15, 2012 Share Posted May 15, 2012 NovaS will be happy that I am UV mapping this engine properly mapped. Very much worth taking the extra hour to wrap it Will texture soon. it is work out time. Will try some new things for texturing to make them smoother.

CardBoardBoxProcessor Posted May 16, 2012 Share Posted May 16, 2012 I guess I should probably make a landing engine for landing. something small and short. whatcha think Link to comment Share on other sites More sharing options...
Nibb31 Posted May 16, 2012 Share Posted May 16, 2012 Actually, your tiny rendezvous engines are pretty good for landing. I especially like the radial ones. Link to comment Share on other sites More sharing options...
Guest Posted May 16, 2012 Share Posted May 16, 2012 Those are nice, but a bit too weak for landings. I\'d definitely like to see a dedicated landing engine. Link to comment Share on other sites More sharing options...
