<Starwaster>
lamont: here's FinalizeOrbit() in Kopernicus. If the field is set for the moon then its orbital velocity takes into account both bodies masses. It's changing the orbit parameters so MJ should be able to calculate the transfer anyway if all it's doing is reading that same data
<UmbralRaptor>
stratochief: I thought that the RL60 got cancelled after it had been tested successfully. >_>;;
<stratochief>
UmbralRaptor: maybe a component or two, which is better than just being paper. but didn't they also test some components of J2-X and/or F-1B ?
<UmbralRaptor>
But, yeah. The cost side of the SSME is disappointing.
<stratochief>
the russians have a cheaper version of the SSME. the US could try and make something similar, but the russians may out-compete them
<stratochief>
are the ESA solids the largest solids ever used / used as boosters?
<stratochief>
wait, derp. shuttle boosters are also huge
<UmbralRaptor>
Not sure on J-2X, I think F-1B fired a gas generator?

<stratochief>
Bornholio: yeah, US does some strange R&D, then just throw it away
<Bornholio>
well i still think the Lox injection crowd helped zero. nevermind i can't verify their math, not that i'm the expert, but it only adds 40MW to a 500mw engine, i call BS for the Thrust number tripling
<Oneiros>
i think ill work on a beginners guide to making the transition to RO
<Oneiros>
maybe starting with just RSS and FAR
<stratochief>
only a 25 page paper? that's not serious :P
<Bornholio>
its a pretty minor topic in all
<Bornholio>
plus you need a background in metalurgy like me to understand what half the article is saying
<Bornholio>
also need to know that previously densityies of 60% were impressive and they are hitting 95%+
<Oneiros>
is that a good minimum do u think? to start by adjusting to the massive scale increase, and getting to orbit and surviving re-entry, still can be done on stock parts
<Bornholio>
i'd say for RSS the min is adding SMURFF or x2ISP mods
<Bornholio>
Real Fuels is the next big hop
NathanKell|AFK is now known as NathanKell
<NathanKell>
o/
Rokker is now known as UgandanKnuckles
<Oneiros>
which ones are they
<Oneiros>
hi NathanKell
<Oneiros>
i didnt have too much trouble getting to orbit in RSS with just stock parts on sandbox mode
<Oneiros>
all the new things added by RO can be overwhelming so maybe best to start with the bare minimum, which already provides a challenge - for some people, a really big challenge
<awang>
Oneiros: How big of a rocket do you need with stock stats to get to orbit?
<Oneiros>
nothing too ridiculous
<Oneiros>
for the tiniest payload (probe core, battery, solar panels), a few tanks and a spark engine upper stage, next stage was the largest 1.25m tank and a swivel engine, then a lower stage of some 2.5 tanks and a mainsail
<Oneiros>
that had a bit over 10k km/s dV
<awang>
Sounds more or less like Sputnik
<Starwaster>
bornholio the LOX increases exhaust mass and combusts in the nozzle. It's sound enough
<Oneiros>
that would be a great way to start haha
<taniwha>
Bornholio: tripling thrust is quite reasonable if Isp is cut significantly
<Oneiros>
should be able to just scale everything up to the next size diameter to allow a 1.25m pod payload, hopefully
<Bornholio>
yeah not enough, not less than half, unless magically its above stochiometrric temp for combustion
<awang>
Oh, right, you're in sandbox
<awang>
I've been in RP-0 mode for too long >_>
<lamont>
Starwaster: not Kopernicus, I replicated in stock-stock with no mods other than MJ
<Starwaster>
hmmm
<awang>
I'd imagine career would be impossible with RSS/FAR
<Oneiros>
ya. career would need a new tech tree. but this is just for a slow adjustment to RO, introducing one new challenge at a time
<Oneiros>
yup i'd say so
<awang>
Are you planning on eventually getting to RP-0/RP-1?
<awang>
Or stopping at RO?
<Oneiros>
yes, that is the end-goal
<Starwaster>
I don't think I've had a problem in stock with transfers lamont
<Oneiros>
but it all looks very complicated and will take time to adjust, its basically a new game, and a deep one
<Oneiros>
from what i can tell anyway
<Oneiros>
maybe if you have an engineering degree and some knowledge of rocketry its ok, but im just an enthusiast
<awang>
Oneiros: Yeah, I'd agree
<Starwaster>
bornholio, 2700K should be more than enough for ignition. You only need about ~500K
<Oneiros>
k cool. i'll work on this guide to follow my own progress in adjusting, and then see if you guys like it and think it would help
<Oneiros>
im sure there are plenty of enthusiasts like me around who would love to learn more by playing RO, but can't handle all the information at once haha
<lamont>
there’s some edge conditions, particularly some transfers to moho with the new button to include a capture burn — and the new code shouldn’t miss by as much as it does sometimes
<lamont>
(the old code always missed by a lot)
<lamont>
people have reported planning-transfer-out-of-jool bugs as well, which makes sense due to the potential for interactions
<awang>
Oneiros: There's always the tried-and-true Kerbal way
<awang>
Throw something together and see what happens
<Oneiros>
one thing i didnt understand was that space starts at 140km altitude, but the karman line is 100km and ferram's guide said that drag stops around there too
<Oneiros>
lol true
<Starwaster>
well it doesnt STOP but it becomes a lot less significant for KSP / RO purposes
<Oneiros>
ok
<awang>
Oneiros: IIRC it's supposed to be the point where you get 1 Pascal of pressure at interplanetary reentry speeds
<Starwaster>
to be more precise, we could model the atmosphere much further than we do but then you can't go above phys timewarp and the amount of drag is so negligible that it's not worth it
<Oneiros>
yeah, the physics timewarp and ships disappearing in atmo are the limitations
<Starwaster>
even the ISS has drag but if we made an atmosphere curve for that, nobody would be happy because they can't warp
<lamont>
there’s “drag” and there’s “drag”
<Oneiros>
ya for sure
<awang>
At least until egg implements orbital decay in Principia
<Starwaster>
actually, the very early RSS did have an atmosphere table that went pretty high. I can't remember how high I actually put it before Nathan capped it at 1pa
<egg|phone|egg>
Meow
<lamont>
110km drag is negligible for a rocket trying to punch through it
<Starwaster>
1pa was considered a good stopping point
<lamont>
110km drag is sufficient to deorbit a satellite in less than a revolution
<Oneiros>
hm
<Starwaster>
try it, it's fun
<awang>
Wikipedia says that 150km is the altitude at which you can make it around at least once
<Oneiros>
oh wow ok
<Oneiros>
the ksp system is very unrealistic
<awang>
How so?
<awang>
Besides the Jool system being unstable
<awang>
And everything being stupidly dense
<Bornholio>
osmium dense
<Oneiros>
well once you reach X altitude you can orbit forever
<Oneiros>
i think you need a third zone in between the two
<egg|phone|egg>
Retrobop ftw
<Oneiros>
instead of calculating drag just force a certain amount of orbital decay, or something
<lamont>
there’s the OrbitalDecay mod which does that
<awang>
Isn't it dead?
<lamont>
i think so
<Oneiros>
but it doesnt work with principia right?
<awang>
There's also Principia (eventually)
<awang>
Probably not
<awang>
Cheat menu and HyperEdit don't work with Principia, so I wouldn't expect OrbitalDecay to be different
<lamont>
the problem of purturbing orbits in Principia is complicated
<Oneiros>
haha ok
<Oneiros>
i love principia
<egg|phone|egg>
Purrtubing
<UmbralRaptor>
…did ANBOcat steal egg's phone?
<Oneiros>
what sort of altitude do you need to minimise decay to the point where it's almost negligible? in reality
<Bornholio>
here kittah
<Bornholio>
600km
<Bornholio>
hubbleish
<awang>
Hmmm
<awang>
How long would it take for Hubble to decay, anyways?
<egg|phone|egg>
UmbralRaptor: egg is not at ANBO at the moment
<Oneiros>
ok. so you'd have stock atmosphere system 0-100km, modded midzone with simulated decay 100-600km, and stock space system 600km+
<Oneiros>
or something like that
<awang>
Or just Principia for literally everything
<Oneiros>
haha ok ya

wow I forgot how often and how early stock KSP likes to throw tourist contracts at you
<Starwaster>
screw all this science shit
<Starwaster>
I made a cheap and scalable tourist solution for them. Mk1 pod + small SRB + decoupler. Cluster as needed for more tourists. Add one probe core or MJ AR202 and toss them onto a sub orbital arc. Jettison and arm the chutes, turn them all retrograde and instant monies! and rep!
<ProjectThoth>
Theory question - you know how three-core vehicles are popular, but an engineering nightmare?
<ProjectThoth>
Would it not be more structurally sound to tie them together into a triangle?
<stratochief>
ProjectThoth: 3 failing attachment points instead of 2? which two stages run dry first, and does the thrust vector to go through the CoM during assymetric throttle back?
<ProjectThoth>
stratochief: Run them at the same time?
<ProjectThoth>
They'd go downrange a bit farther, but eh.
<stratochief>
a good chunk of the value of 3 cores with to side boosters is that you run them assymetrically
<stratochief>
so less energy is wasted propelling those dry stages
<ProjectThoth>
Attempting to find the picture I have in mind here...
<Oneiros>
awang: using smurff to change stock engines and fuel tanks to more realistic values, orbit can be achieved using just a few more fuel tanks than stock
<Oneiros>
stock career might even be playable with smurff + RSS
<wb99999999>
well look who's here
<wb99999999>
1.5 stage advocate is back!
<wb99999999>
ProjectThoth: I've been building a 1.5 stage LV for a Venus probe
<wb99999999>
it's pretty good but the payload capacity is a little low
<stratochief>
wb99999999: like, a ground-lit engine flies near venus?
<ProjectThoth>
wb99999999: Sounds about right.
<wb99999999>
XD
<stratochief>
wb99999999: that'd be nearly as crazy as throwing your car at Mars
<wb99999999>
what
<wb99999999>
that Tesla roadster is going to Mars?
<wb99999999>
I thought it's going to some nowhere in deep space
<stratochief>
if everything goes swimmingly, it'll be at mars' distance from the sun
<Bornholio>
mars solar orbit, not to mars
<Oneiros>
how do you have half a stage
<Bornholio>
love how the media willfully blast that its going to mars
<Oneiros>
whaaat
<wb99999999>
basically a half stage is when you throw away only the engine and structures, but not tanks
<wb99999999>
aka, Atlas D
<stratochief>
Oneiros: look at the Atlas LV from murica
<Oneiros>
ah ok, ty
<Oneiros>
and i thought the teslta was going to mars orbit
<Oneiros>
*telsa
<Oneiros>
ugh, *tesla
<wb99999999>
half stage is really only practical with RO because tanks can get sufficiently light
<wb99999999>
stock tanks are way to damn heavy
<stratochief>
naw, even for a near flyby it would have to occur at a very specific launch window time that occurs once every ~2 years.
<Oneiros>
far out
<Bornholio>
plus planetary protection office would have a freakout
<wb99999999>
but would the first launch be landing any boosters?
<Bornholio>
yes
<Oneiros>
so he's just testing that the heavy has enough dV to get there
<Oneiros>
lame. i think the media did lie.
<stratochief>
Oneiros: nah, the test launch is to test the whole setup, blast off, recovery, all that jazz. lots of moving parts that've never been tested in practice
<Oneiros>
ya true, i shouldn't oversimplify
<wb99999999>
it needed a launch to prove itself anyway
<wb99999999>
that roadster is just a publicity stunt
<stratochief>
media oversimplifies, because the avg person barely knows mars is a planety
<wb99999999>
okay back to that rocket I've made...
<stratochief>
wb99999999: right. so, ground lit engine flies by mars?
<stratochief>
*venus?
<wb99999999>
Orz no?
<stratochief>
ahh, so 1.5 stage to orbit, then
<Starwaster>
Oneiros not all stock, no. And it's 10x Kerbol (scaled up 10x). I've got some KWR parts, some SSTU parts and I patch cloned some of the 5m KWR parts to 10m
<wb99999999>
it's like that 1.5 stage Saturn thing
<wb99999999>
except much, much smaller
<Starwaster>
scaled up 5m Titan V to 10m Titan X (for the Saturn V SII) and also made MEC to re-configure it as the Ares V core engines x5
<Oneiros>
ok nice
<Oneiros>
are you using the smurff mod?
<Starwaster>
no
<Starwaster>
what does that do, turn kerbals blue?
<Oneiros>
lol it gives engines and tanks more realistic stats
<Oneiros>
*stock engines and tanks i mean
<Starwaster>
that's what RF does
<Bornholio>
tank mass fractions
<Starwaster>
I was just kidding, I know about smurff. don't need it
<Oneiros>
ok i will investigate this RF
<Starwaster>
RF + some of (but not all of) RO
<Starwaster>
get ready for boiloff
<Starwaster>
and not the fake boiloff that some of the other mods do.... based on actual heat penetration into your tanks
<wb99999999>
the booster is not quite enough to orbit the thing anyway so I stretched the Centaur and have it insert me into orbit

but remote tech is already cpu heavy
<awang>
Oh, really?
<awang>
I had no idea
<awang>
What part eats the most CPU?
<Bornholio>
any part with a conic adds quite a bit to the load, omnis all add together as one spherical distance per craft. plus with RSs we have lots of ground stations to link too

Huh
<awang>
I had no idea it was that expensive
<Bornholio>
calculate if two cones orbiting two spheres are occluded by those spheres or and other spheres inthe local region. repeat for all such antennas in local region, one second later repeat

<Starwaster>
bornholio: to answer your question there's a couple of things I want to get done with PP before I update it. Most important among them is reworking the procedural SRB to fix the gimbal

<Bornholio>
The new Dev tree is awesome
<Bornholio>
all new icons, special tricks for KCt integration
<Oneiros>
oooh sounds nice
<Bornholio>
awang is the second RP0 dll for dev?
<Bornholio>
will these run dev?
<Bornholio>
am i crazy
<awang>
Bornholio: Second RP-0 dll?
<awang>
Also, glad to hear that things are working
<awang>
I was thinking that if we want to get a release ASAP we might want to consider disabling training stuff while kinks are worked out
<Bornholio>
noticed tree was borked a bit for RP0, didn't, (RP0KCTBinder)
<Bornholio>
didn't think i grabbed dev
<Bornholio>
but it was throwing exceptions in R&D when i clicked on nodes
<Bornholio>
and had a lot of empty nodes
<Pap>
If I have to guess awang, I would think that NK would want to wait for kinks to be ironed out.
<Probus>
Falcon Heavy SF got pushed back to Friday. :(
<Bornholio>
still clamps?
<Probus>
Dunno for sure, but I am sure that is something you want to work right. That would be embarrassing if half the rocket launched.
<Bornholio>
they had guys on the clamps last time
<Probus>
Does anyone know if the FH decouplers pump fuel/lox to the center stage?
<Bornholio>
they don't
<Bornholio>
was on the early wishlist, but center is run low power instead
<Probus>
Has any rocket ever successfully done that?
<Starwaster>
Github Desktop won't let me delete my branch before committing my changes because they would be lost....
<Starwaster>
oh the irony
<Starwaster>
THE IRONY IT BURNS
<Bornholio>
you funny guy
Bornholio has quit [Read error: Connection reset by peer]
Bornholio has joined #RO
<Starwaster>
OH NO! I deleted my branch and now I lost my changes that I just committed!!! Whatever will I DOOOOoooo
<Oneiros>
wat
<Starwaster>
You didn't see what happened Oneiros? Do you want to hear my sad tale of woe?
<Starwaster>
It all started when I innocently tried to delete a branch in github and it told me that it wouldn't let me do it because I had uncommited changes and it didn't want me to lose them
<Starwaster>
so I thought well... that's sensitive and thoughtful of it
<Starwaster>
so I committed my changes to the branch and then I deleted it... AND I LOST MY CHANGES ANYWAY!
<Starwaster>
Oh the pain....
<Bornholio>
github whacked him with a whole branch of the stupid tree
<Starwaster>
it whacked me right in the privates
<Starwaster>
and then it was mean to my puppy and stole my lunch monies
<Bornholio>
okay sergeant
<Bornholio>
plus we all nknow its your kittah
probus_ has joined #RO

<Oneiros>
does anyone know if this data is still current?
<Bornholio>
not with FAR :P
<awang>
Uh
<Oneiros>
true. rats.
<awang>
Bornholio: I have no idea what's going on, assuming I'm looking at the same exceptions you were
Hypergolic_Skunk has quit [Quit: Connection closed for inactivity]
<awang>
My first guess would be maybe a part (or part upgrade) is specifying a nonexistent icon
<awang>
Hmmm
<awang>
Bornholio: This is RP-0, right?
<Bornholio>
that could be, but then it should squelch it on load not in the UI
<Bornholio>
yes RP-0 Master
<awang>
True
<awang>
Unless it's lazily loaded?
<wb99999999>
...no this really bugs me now
<wb99999999>
why does a rocket get less drag if it's going faster in the atmo?
<wb99999999>
I have heard this before when someone was talking about the Sea Dragon and they went something like because it has a high acceleration and large mass the drag is minimal
<Bornholio>
lttle planes have tousands of dV in drag losses but hundreds of thousands of dV
<Bornholio>
thousands
<awang>
Bornholio: I'll need to try booting KSP later. Recently I've only tested whether KSP loads, not whether career still works
<awang>
Although given that there were so few changes since I last did career, I'm not sure what I'd find
<awang>
wb99999999: Ask our local aero expert?
<Bornholio>
I always have have verbose logging on screen so more things bug me also
<wb99999999>
is he on?
<awang>
Maybe it's because you're spending less time in-atmo?
<awang>
Or are taking a more vertical trajectory?
<awang>
idk? I know he gets pings
<awang>
ferram4: wb99999999 has a question
<wb99999999>
that's my initial thought
<wb99999999>
but there's times when I gravity turn VERY hard because I have high TWR
<wb99999999>
and I went fast lower in the atmosphere
<wb99999999>
still got less drag loss
<ferram4>
Hmm?
TM1978m has joined #RO
<ferram4>
Rockets that go faster always have higher drag FORCES, but not necessarily higher drag VELOCITY LOSSES.
<wb99999999>
I am listening
<soundnfury>
wb99999999: note that some kinds of drag peak around M=1.0
<soundnfury>
Prandtl singularity and all that ;)
<ferram4>
Drag coefficient peaks.
<ferram4>
Drag force itself does not.
<wb99999999>
so it lose less...momentum? to the drag?
<ferram4>
And the Prandtl singularity isn't a thing. It's an error in the linear model of compressibile aerodynamics.
<ferram4>
Remember that drag force acting on something produces acceleration, not velocity.
<ferram4>
That acceleration needs to be integrated over time to get velocity.
<ferram4>
So, theoretically, a rocket that spends more time under a lower drag force (and thus, acceleration) can end up with greater dV drag losses simply because of the time component.
<wb99999999>
right
<soundnfury>
ferram4: that (it not being a thing)'s why I put the ";)"
<awang>
Bornholio: I have that on, too, but I never had issues with R&D
<awang>
Only issue I can remember is Hide Empty Tech Tree Nodes tanks my FPS if I haven't unlocked all the tier one nodes
<Bornholio>
k then I'll scrub out RP0 and troubleshoot
<awang>
Sorry :/
<awang>
"Works on my machine, try again" isn't that helpful
<Bornholio>
hah, yes it is
<Bornholio>
reduces the equation to PEBKAC
<awang>
Which KAC remains to be seen :P
<wb99999999>
ferram4: so basically, because you spend less time under drag, you spent less time under drag
<awang>
wb99999999: ...That sounds tautilogical
<Bornholio>
dv=at
<ferram4>
It is a possibility for why equal mass rockets end up with lower drag losses by accelerating more.
<awang>
s/ti/to
<Qboid>
awang meant to say: wb99999999: ...That sounds tautological
<ferram4>
I still think that mass differences are more to blame though.
<ferram4>
Drag tends to go with area, mass tends to go with volume.
<awang>
More mass = higher ballistic coefficient?
<ferram4>
Cube-square law and all that.
<wb99999999>
you're right
<wb99999999>
a few weeks ago I got bored and made a light LV with hydrolox
<ferram4>
awang, Well, it is in the definition. m/(Cd*A)
<wb99999999>
and it's absolutely terrible
<awang>
ferram4: True. Wasn't sure what the formula was, hence the question mark
<awang>
Formula makes it blindingly obvious though
<wb99999999>
well here's another reason to go for dense fuel then
<soundnfury>
wb99999999: it's probably partly terrible because hydrolox first stages are terrible *anyway* for gravy drag reasons
Oneiros has quit [Ping timeout: 180 seconds]
<awang>
"gravy drag"
<wb99999999>
it's not as bad if I made a heavier and longer rocket though
<soundnfury>
(higher Isp = slower delta M = more time at low TWR = more dV to reach orbit)
<awang>
The most delicious part of rocket engineering
<soundnfury>
awang: Yes, that is what I call it, do you have a problem with that? :)
<wb99999999>
I think someone called that phenomenon the "jerk effect"
<awang>
soundnfury: Not at all
<awang>
Is that your version of stabbity?
<Bornholio>
jerk is the rate of change of the rate of change of the rate of change
<soundnfury>
Oh, I use that one too, but that's probably shadowbirb's fault
<soundnfury>
wb99999999: yeah, but I think we should call it some eponym of Mitch Burnside Clapp, its discoverer
<soundnfury>
something about rockets that go like the clappers, maybe ;)
