Hi all. Anybody awake?
<DeadManWalking>
<- is sad. My RO Saturn V only has a TWR of .31 :(
<Hohman>
The obvious solution is to weld several of them together.
<DeadManWalking>
a bunch of them at a TWR of .31 still won't go up lol!
<DeadManWalking>
given the fudging of the numbers it is almost like the 1b and V only get thrust from 1 engine?
<DeadManWalking>
each F1 was around .3 (7.9 thrust vs 6.1 wet weight, no?)
<DeadManWalking>
wet launch TWR for 1b and V was around 1.3ish right?
<blowfish>
lower than that, at least for the Saturn V
<blowfish>
I don't recall the exact number but I know it was below 1.2
<leudaimon>
1.1 iirc
<DeadManWalking>
yeah I think thats the 1b... wiki (for what *thats* worth) says V was 7.8lbf at sea level with wet weight of 6.5 for TWR of ~1.2 but I've only got .31 with RO :(
<DeadManWalking>
so should I give up on RO for now?
<leudaimon>
are you using 5 F1s? if the mass is the same as saturn V (about 3kT) you should get the correct twr
<DeadManWalking>
I haven't done the math on the soviet launch vehicles but they seem underpowered as well but not as bad
<blowfish>
err, might have been above 1.1
<blowfish>
1.2, sorry
<DeadManWalking>
I'm using the latest RO stock craft file
<blowfish>
Wikipedia's numbers give between 1.18 and 1.21
<DeadManWalking>
it shows the right weights and thrusts for the F1's but all stages show way low TWR's
<leudaimon>
that's weird
<DeadManWalking>
I only get .31 with the stock RO craft file. I tried rebuilding the fisrt stage manually with same results
<DeadManWalking>
thats what I said ("thats weird")
<leudaimon>
maybe you have a problem with the install, or with mechjeb
<DeadManWalking>
I know it's not released and all but when I finally got it all working of course I wanted to try the V
<blowfish>
longshot, but maybe as Scott Manley says, check yo staging?
<DeadManWalking>
I tried pulling all the commits and building the latest from FASA and RO and there is a strange RCS issue so I'll have to reinstall everything again to fix that but I'll try sans mechjeb first
<DeadManWalking>
again, its the RO stock craft file from github
<DeadManWalking>
but I did scott at it for a while
<leudaimon>
where did you check twr if you have no mechjeb?
<DeadManWalking>
and I checked the RO update cfg.s and they are as expected. I just wanted to double check that there wasn't a known issue with the 1b and V
<DeadManWalking>
I have mechjeb and engeneer
GradingRaptor is now known as UmbralRaptor
<DeadManWalking>
both give twr and both agree (and the craft won't go up)
<blowfish>
all engines reporting the correct thrust when you ignite them?
<DeadManWalking>
checking
<DeadManWalking>
while its loading, back to scott manley, while I was waiting for ksp to load this morning I watched all of his engine / nozzle / fuel "what KSP doesn't teach you" vids again. Seemed like a Funky Speck for RO lolz
<DeadManWalking>
1.556kn on each F1 on the pad
<blowfish>
that seems rather now
<blowfish>
*low
<DeadManWalking>
yeah wiki says Thrust (SL)1,522,000 lbf (6,770 kN)
<leudaimon>
yep, you might not have the RO MM changes
<DeadManWalking>
yeah 1500 is what it says in the VAB, checking the RO FASA .cfgs
<DeadManWalking>
FASAApolloLFEF1?
<DeadManWalking>
@maxThrust = 7740.5
<DeadManWalking>
that's my problem
<blowfish>
that seems correct. Is the problem that it's not applying?
<DeadManWalking>
correct
<blowfish>
next step would be to look at the log then
<blowfish>
assuming that MM didn't load from cache on the last game load
<blowfish>
(if it did, the important information will be lost and you will need to delete GameData/ModuleManager.ConfigCache and reload the database)
<DeadManWalking>
I deleted the MM cache files at least once today
<blowfish>
only the last start of KSP makes it into the log
<DeadManWalking>
I've been fighting with this for a couple of days now but I wanted to rule out my usual stupid mistakes before I asked for help ;)
<blowfish>
if MM doesn't use the cache, it logs each patch that is applied.
<blowfish>
but the log is wiped out each time you start KSP
<DeadManWalking>
yeah I found it in FASA: maxThrust = 1550
<DeadManWalking>
so I'm convinced the new thrust val isn't getting applied from RO_FASA_Saturn.cfg, so now I know what to look for.
<DeadManWalking>
*RFMEC* ERROR Can't find configuration F-1, falling back to first tech-available config.?
<blowfish>
that's just KSP acknowledging that the config exists
<blowfish>
there should be a separate line where MM applies it
<blowfish>
best way is probably to search for the part name (FASAApolloLFEF1)
<DeadManWalking>
yes I was, sorry the penny just dropped on the previous comment about the mm cache
<DeadManWalking>
deleting cache and restarting to check the logs again :)
<DeadManWalking>
ok think I found it:
<DeadManWalking>
[LOG 00:41:10.865] [ModuleManager] Applying node RealismOverhaul/RO_SuggestedMods/FASA/RO_FASA_Saturn/@PART[FASAApolloLFEF1]:FOR[RealismOverhaul] to FASA/Apollo/FASA_Apollo_Eng/LFE_F1/FASAApolloLFEF1
<DeadManWalking>
so that looks like MM is applying the .cfg, no?
<DeadManWalking>
Ok, when I look at the F-1 in the VAB the description says the correct thrust, but in real fuels the thrust is the original value (about 1.6)
<DeadManWalking>
and it looks like that is what is being reported for the TWR and physics in game
<blowfish>
ah hmm
<blowfish>
then the problem would likely be in ModuleEngineConfigs
<DeadManWalking>
hmm, I don't see the 3 available fuel types for the F1 in the engine configs
<DeadManWalking>
you have been very helpful, I know where to start looking now I think, thanks! I'll have to hammer at it again tomorrow.

So, my Heat Pump mod depends on knowing how much incoming conduction flux there is so it can counter it. But in analytical mode that information becomes unavailable. SHIT.
<stratochief>
Starwaster: maybe take the last reported value, adjust it based on the other info that is available during analytic?
<stratochief>
like, are you able to find the temperature of attached parts during analytic? that should be a useful factor for scaling your estimation by
<Starwaster>
stratochief: analytic reports (BEFORE it actually sets) the intended temperature of a part. I could calculate an approximate incoming conduction flux based on that. (since I know how much heat is actually going to be required to effect that change so I know how much to counter it by)
<stratochief>
Rokker: was the Titan II tankage definitely not reflective metal, or does it just appear that way due to lighting?

Hi all. I tested the RO / FASA Saturn V with a clean install and only the RO suite. The thrust for the F-1 / J-1 is being set by RF instead of RO and I have two Engine Gui buttons. Should I just manually delete the RF stockalike config files? (they are required via CKAN)
<stratochief|away>
ferram4: any progress on the FAR front? the RO and RP-0 pre-requisites are starting to come together, it would be awesome to have a FAR as well so RO will be CKAN-able

I've been obsessed with finding the right skin-internal conduction value that I never realized how much heat was pouring in from other parts
<Starwaster>
it's horrible
<Starwaster>
I mean I knew it was bad but it's much MUCH worse than I even imagined it could be
<stratochief>
Starwaster: indeed it is.
<stratochief>
is it.. 5x too high? :P
<Starwaster>
it depends on the size and mass of the thing you're concerned with
<Starwaster>
it's high even for small parts but here's the thing:
<Starwaster>
it does not change for larger more massive parts
<Starwaster>
heat conduction for a given material is halved if you double the distance it has to conduct through
<egg>
moo?
<Starwaster>
and that's assuming a solid part not a hollow one like a tank
<egg>
ah nevermind someone said double
<stratochief>
Starwaster: yikes. is there a way to change that (same for small and large parts) but adjusting by the mass or something?
<Starwaster>
without rewriting the thermodynamics conductivity code what you'd have to do is alter part.heatConductivity
<Starwaster>
there's a downside to that
<Starwaster>
if you alter heatConductivity you not only change part-part but also skin-skin and skin-internal
<Starwaster>
it's all interconnected
<Starwaster>
so if you want something like skin-internal to stay constant you CANT change heatConductivity without also changing part.skinInternalConductionMult
<Starwaster>
it's all of it ALL OF IT relative one to another
<Starwaster>
it does NOT lend itself to precise changes at all
<Starwaster>
juggling the different values is like playing whack a mole
<Starwaster>
do you see why boiloff is such a problem in Real Fuels?
SirKeplan|afk is now known as SirKeplan

* stratochief
can see Starwaster's patience boiling off
<Starwaster>
(ok not really, there's room for improvement but stock thermodynamics is seriously screwing us here)
<stratochief>
thermodynamics is hard. NK did fairly well making the stock thermo system, given his background is not in thermodynamics
<Starwaster>
dont get me wrong, it's in many ways an improvement over what we used to have but it introduced a whole new slew of issues
<stratochief>
and orders of magnitude better than the utter gamified nonesense that roverdude plays with CoreHeat
<Starwaster>
yeah but, what I'm talking about? the different variables that all affect each other?
<Starwaster>
he and I had a discussion on that previously
<stratochief>
indeed. part to part conduction is crazy high
<Starwaster>
it makes it hard to tweak things when changing one variable REQUIRES changing multiple other variables
<stratochief>
hard indeed. like, needs a renormalization step to adjust everything else to stay the 'same' (in outcome) when you just wanted to adjust one part
<Starwaster>
both PhysicsGlobal.conductionFactor and part.heatConductivity can not be changed without altering every other aspect of of the conduction simulation

Tried to play KSP this weekend. Found I had deleted it but had a ZIP backup. Unzipped it and ran, everythign looked good. Got in my old campaign and had a rocket ready to go so laiunched it. Used MJ Autopilot to handle ascent and all went well with first stage, then staged into the second stage and after a bit decided to disable AP so I could adjust insertion. Turned off AP and MJ cut throttle and there went that engine.
<Agathorn>
Decoupled, turned on RCS and turned on SmartASS to hold Prograde, no problem. Translated forward to ullage and fired up the third stage. Then SmartASS for some reaosn couldn't hold prograde and the rocket started driving in circles. Shut the engine down, realigned prograde, and relit the engine. circles again. Alt-F4'd.

actually I'm pretty excited about 1.2.2 RO since Principia now makes the solar system work correctly.
<egg>
egg!
<stratochief|away>
Starwaster: my test craft was taking in 5 kW of heat per solar panel, and conducting it to the fuel, so kind of a zero sum game trying to power the HeatPump using solar energy :)
<Starwaster>
if you're using the development version I gave you the link to along with the setting for conductivity that shouldn't matter
<Starwaster>
in fact the conductivity setting I'm currently using is horribly overpowered
<Agathorn>
Does Principia work yet with things like MJ or KRPC?
<egg>
define work
<egg>
or not work
<Starwaster>
LOL
<Agathorn>
the opposite of not work
<Starwaster>
it works for certain values of 'work'
<Agathorn>
:)
<egg>
but how do you define not work
<xShadowx>
does it really matter? you're installing principia either way ;p
<Agathorn>
I just remember once you saying you couldn't use MJ with it
<egg>
it works okish when the Keplerian orbit is decent
<egg>
when you do harder things MJ makes false assumptions
<Agathorn>
which is the main reason I never tried it because there is no way in heck I am manually flying

Agathorn: for non-low-orbit flight planning you'll want to use our flight planning, and burn by hand
<Agathorn>
of course as evidenced by this weekend I MJ isn't even working properly without principia for me :p
<egg>
for launch and low orbit ops stock-style works
<Agathorn>
I don't like to play KSP as a pilot, so I tend to script the heck out of my launches and flights
<egg>
launching sure; but the trajectory planning is actually hard with principia, it's not the stock automatisms
<egg>
and we don't have much burn assistance besides putting a vector on the navball
<egg>
so you can point the vehicle in the right direction, but you need to manually ignite/cutoff while watching the prediction converge to the flight plan
<Agathorn>
so if I grab the positions of things and crunch the math to determine burn, that won't work?
<Agathorn>
or the math has to be more invovled I guess?
<egg>
well I mean, if you do your own integration on your side, sure, you can burn however you want
<egg>
back to the computer too :-p
<egg>
but, well, it took us a few years to write the libs to do those integrations :-p
<Agathorn>
yeah so it becomes much more complicated, integration rather than simpler math gotcha

KRPC probably can't even see Principia placed bodies anyway :(

Can I still use conics to predict launch windows egg?
<regex>
Yeah, that works. i don't need it to tell me how to set up a maneuver or anything, i just need to rely on times and delta-V estimates from the porkchop plot.

regex: if it's a good rule of thumb IRL it is in principia
<egg>
so conics work, if you're dominated by one body
<egg>
patchy conics work, if you spend most of your time dominated by one body
<egg>
etc.
