L97[05:52:04] <Fluburtur> I was contacted
by my old mechanics teacher, wants me to come play bass in his
band
L100[05:54:13] <TheKosmonaut> A bit of an
exaggeration but this is why I can't stand NDT
L101[05:54:20] <Althego> hehe
L102[05:54:29] <Fluburtur> same
L103[05:54:54] <Fluburtur> isn't he a
theorical physicist or something?
L104[05:56:46] <TheKosmonaut>
Astrophysics, physical cosmology iirf
L105[05:57:32] <Fluburtur> I remember in a
video of smarter every day when he was like "a heli cannot fly
if the engine dies it will jsut fall" I guess he was kinda
playing a role but still
L106[05:57:50] <Fluburtur> and he could
tell me about how to cook food but I would still trust my grandma
more
L107[05:57:57] <TheKosmonaut> He's
definitely smart... But he makes a lot of blunders on Twitter
L108[05:58:31] <TheKosmonaut> Like when he
said that bb8 rolling on the sand in Star wars was physically
impossible
L109[05:58:40] <Fluburtur> ehhh
L110[05:59:00] <Fluburtur> don't talk
about stuff outside your area of expertise neil
L111[05:59:14] <TheKosmonaut> Then the
Star wars people in the prop Dept sent him a video of the remote
bb8 rolling on the dunes
L112[05:59:18] <Fluburtur> you are a
physicist but clearly not a mechanical engineer
L113[05:59:32] <Althego> every famous
scientist does that. and it is well known that they all fail when
they do
L114[06:01:41] <Fluburtur> he does that
pretty often
L115[06:06:29] <Mat2ch> TheKosmonaut: It
may depend on the sand
L116[06:06:41] <Mat2ch> and the weight of
a BB8
L117[06:06:53] <APlayer> What's a
bb8?
L118[06:07:12] <APlayer> (I have not
watched Star Wars, so please don't kill me)
L119[06:07:15] <Mat2ch> sand can be rock
hard, but also like a fluid
L120[06:07:21] <Fluburtur> a ball version
of r2d2
L121[06:07:37] <Mat2ch> APlayer: I don't
watch Star Wars either. But it's a rolling ball with a head that
stays on top ;)
L122[06:07:37] <APlayer> R2D2 is that
robot assistant thingy?
L123[06:07:44] <Fluburtur> yeah
L124[06:07:45] <Mat2ch> yeah
L125[06:07:50] <Fluburtur> that looks like
a trash can
L126[06:07:51] <APlayer> Alright, got
it
L127[06:08:45] <Mat2ch> and if the ball
has a very smooth surface and is heavy and the sand is very fine
grain BB8 might really be stuck there
L128[06:09:16] <APlayer> And why exactly
would it not be able to roll on sand?
L129[06:09:18] <Fluburtur> he does have a
lot of panels everywhere
L130[06:10:20] <Mat2ch> APlayer: because
the sand could act as ball bearing
L131[06:10:29] <APlayer> Ah
L132[06:10:42] <Fluburtur> I xould be more
worried about wet sand sticking to it
L133[06:10:49] <Mat2ch> mud. :D
L134[06:10:51] <APlayer> Well, I guess
that's called "traction" and a whole field of science on
its own?
L135[06:11:11] <Fluburtur> yeah
L136[06:11:21] <Fluburtur> we were
supposed to learn about that in mechanics but never did
L137[06:12:19] <APlayer> So a rough
surface would probably rather be able to roll on sand than a smooth
surface
L138[06:12:54] <APlayer> But it also
depends on how the sand "flows" in itself and the
friction force between the surface and the sand
L140[06:14:02] <APlayer> Looks pretty
smooth to me
L141[06:14:18] <Fluburtur> yeah bit at the
joint between panels and stuff
L142[06:14:28] <Fluburtur> I mean as long
as it doesn't sing too low in the sand it should be fine
L143[06:14:48] <APlayer> But still, the
panels could have any sort of properties
L144[06:15:20] <APlayer> I don't think a
normal steel ball of this shape could roll on normal sand, but
given special circumstances, why not?
L145[06:16:11] <Gasher[work]> steel ball
yeah, but sphere :)

(Kabouik_!~kabouik@236.34.200.37.customer.cdi.no)
L147[06:16:29] <APlayer> Given that such a
thing would probably have been manufactured with extra traction
(that's it's main propagation method, isn't it?) and Star Wars is
science fiction, the panels could be made from any sort of grippy
material
L148[06:16:48] <Fluburtur> rubber
paint?
L149[06:17:05] <APlayer> Something like
that
L150[06:17:11] <Fluburtur> but it looks
and sounds very metallic in the movies
L151[06:17:13] <APlayer> Though it has to
be durable
L152[06:17:19] <Fluburtur> like only a
thin layer of orange paint at most
L153[06:17:59] <APlayer> Perhaps it is
able to move its panels slightly in such a way that they scoop up
sand?
L154[06:18:06] <Fluburtur> yeah
L155[06:18:11] <Fluburtur> that would
probably do it
L156[06:18:25] <Fluburtur> then it would
be full of sand
L157[06:19:19] <APlayer> Well, of course
it would not allow the sand to actually get inside

tungsten, but a small piece
L264[07:15:08] <Althego> also a really
hard material, not really workable with the usual methods
L265[07:15:23] <Gasher[work]> what
L266[07:15:50] <Gasher[work]> that piece i
have is alloy and it is machinable
L267[07:16:04] <Althego> "In its raw
form, tungsten is a hard steel-grey metal that is often brittle and
hard to work."
L268[07:16:33] <Althego> ok it also says
if it is very pure you can do stuff with it
L269[07:16:42] <APlayer> Tungsten on its
own is brittle, you need to mix stuff into it to make it
softer
L270[07:16:52] <Gasher[work]> it's not
raw, as i said it is alloyed but i don't know which alloy exactly
it is
L271[07:17:19] <Gasher[work]> i guess it
would be the one that gets harder after temperature treatment
L272[07:17:49] <APlayer> I wonder, though,
if you coat tungsten with ceramic on the outside, wouldn't that
make a rather strong vessel to contain, say, a reactor core?
L273[07:18:05] <JCB> just 3d print
it..

L286[07:21:51] <APlayer> Alright, tungsten
carbide with titanium?
L287[07:22:54] <Iskierka> titanium isn't
magic and if this was space-limited tungsten carbide would be
better than almost everything else due to density
L288[07:23:15] <Iskierka> if mass limited
then due to the likely cost to begin with you're probably better
off with inconel
L289[07:23:19] <Althego> you cna also try
silicone carbide and obron nitride for hardness
L290[07:23:35] <Althego> maybe al2o3

L417[09:10:03] <Eroc|2> I'm wondering, I
built a station module using InfernalRobotics for some double
folded Solar Array Beams. Each held a ton of solar array the 1x6
standard modules. Starting the module went fine, deploying them
worked as intended
L418[09:10:55] <Eroc|2> yet as I returned
to the Station the Kraken had taken a hold of the solar arrays and
they were spinning around violently exerting enormous torque on the
station
L419[09:11:23] <APlayer> Reload from a
quicksave
L420[09:11:47] <APlayer> IR contraptions
are prone to Kraken attacks indeed
L421[09:12:04] <Eroc|2> so do a F5 - F9
and hope for the best?
L422[09:12:19] <APlayer> Uh, no F5
L423[09:12:31] <APlayer> Revert to an
earlier stage
L424[09:12:46] <Eroc|2> there was now
previous quicksave so ... nothing to go back to
L425[09:13:08] <APlayer> If that is
impossible, try switching to KSC and back to the station
L426[09:13:33] <APlayer> Even if that
fixes the spinning, there might be damage, check things
carefully
L427[09:13:40] <APlayer> And quicksave
when using IR
L428[09:15:00] <Eroc|2> okay ... Thanks
for the tips.
L429[09:15:44] <APlayer> If that does not
fix the spinning or the spinning comes back again, a screenshot of
the station would be helpful in finding the issue
L430[09:16:12] <APlayer> In the worst
case, replace the IR modules with conventional ones
L431[09:16:29] <Eroc|2> Quicksave is a
little bit problematic as I do often several long time missions
parallel - I saved the station this time by decoupling the module
and getting it to a deorbit trajectory
L432[09:16:50] <APlayer> Humm, I see
L433[09:17:27] <Eroc|2> whicha shame for
the expensive life support modules on it - but that is the price of
exploring space - with a ton of mods :D
L434[09:17:55] <Eroc|2> better then giving
up the whole station
L435[09:19:32] <APlayer> Well, I guess
just try to avoid using IR in weird places, the mechanics
circumvent a lot of internal KSP stuff which leads to random
bugs
L436[09:20:06] <APlayer> And if things
break, consider it a component failure and abort the mission
:P
L437[09:20:31] <Eroc|2> yeah probably IR
should be limited to short fun stuff but not in creating elaborate
foldable space-stations

semipermanent uses of IR that are reasonable are simple folding
lander mechanisms
L441[09:23:21] <Iskierka> those tend to be
simple enough (and built with folded as default) that they don't
glitch out

L454[10:16:29] <Mathuin> Back from driving

script.
L455[10:16:43] <Mathuin> Also, kOS lets
you print at a particular point -- how can I tell where the next
print will be?
L456[10:19:47] <Mathuin> So my vis visa
equation gives me the following results: Pe V is computed to be
7731m/s, Ap V is 1137.7, delta between is 6593, burn time of 59
seconds.
L457[10:20:18] <Mathuin> When I create the
node, the game says that's a 103 second burn and that my Pe will be
-496k instead of 100k.
L458[10:21:43] <umaxtu> are you using
RSS?
L459[10:21:49] <Mathuin> No RSS/RO
here.
L460[10:22:23] <APlayer> The node does not
account for burning off fuel, indeed
L461[10:22:37] <umaxtu> maybe try
installing the better burn time mod?
L462[10:22:50] <Mathuin> It is installed,
I think that's what's telling me 103s
L463[10:22:52] <APlayer> Rely on vis
viva
L464[10:22:56] <Mathuin> I'm trying to do
the math in kOS.
L465[10:23:07] <Mathuin> Is 1137 m/s a
reasonable value for orbiting at 100km ?
L466[10:23:14] <Mathuin> s/orbiting
at/orbiting Kerbin at/
L467[10:23:22] <APlayer> Uh, rely on
tsiolkvsky, that is
L468[10:23:48] <APlayer> Well, usually it
is 2200 m/s, IIRC
L469[10:24:08] <APlayer> But given the PE
velocity, I'd assume this is not an orbit yet
L470[10:24:26] <Mathuin> It's just after
the gravity turn, for context.
L471[10:24:39] <APlayer> Yeah, this is a
suborbital trajectory
L472[10:24:50] <APlayer> The periapsis is
below the surface
L473[10:24:55] <Mathuin> That is
correct.
L474[10:25:17] <APlayer> So if you managed
to get there and not crash into Kerbin, your orbital velocity would
be 7731 m/s
L475[10:25:21] <Mathuin> For
v=sqrt(gm(2/r-1/a)) is that r and a from my target orbit or my
current one?
L476[10:25:35] <Mathuin> Yes, if there
were a giant burrito sized tube through the planet, I would be
zooming along at that speed. :-)
L477[10:25:39] <APlayer> And you pretty
much don't care about the PE velocity at this point
L478[10:26:05] <APlayer> What you need is
the AP velocity and the velocity at the same spot if the orbit was
circular
L479[10:26:17] <Mathuin> Mmm.

L482[10:26:36] <APlayer> You follow

L483[10:26:41] <Mathuin> No.
L484[10:26:52] <Mathuin> I have the AP

L485[10:26:55] <APlayer> So, you are at AP
on a suborbital trajectory
L486[10:27:03] <APlayer> But your target
is a circular orbit
L487[10:27:08] <Mathuin> Yes.
L488[10:27:22] <Mathuin> "the
velocity at the same spot [where, AP?] if the orbit was
circular"
L489[10:27:30] <APlayer> Now, you need to
see what the velocity at AP /already/ is, because that's what you
already have
L490[10:28:18] <Mathuin> "I have the
AP velocity ... for the orbit I am in."
L491[10:28:23] <Mathuin> That makes sense,
and I have it.
L492[10:28:24] <APlayer> And to find out
what you lack, you also need to know what your goal is, i.e. the
velocity of a circular orbit that the same altitude
L493[10:29:29] <APlayer> This is obtained
from the circular orbit vis viva simplification you will find on
Wikipedia (or really, just derive it yourself, where a = r)
L494[10:30:57] <APlayer> Got it?
L495[10:31:10] <Mathuin> I already think I
understand the vis visa equation.
L496[10:31:12] <Mathuin> THe problem is
the inputs.
L497[10:31:49] <Mathuin> I have modified
my script to return the current ap velocity (1137ish) and the
necessary velocity from an orbit with that same altitude and a
semimajor axis equal to twice the sum of the apoapsis and radius,
which now that I think of it is too much.
L498[10:32:12] <Mathuin> The resulting
node is 1613ms and will result in an ap of 150k and a pe of
100k.
L499[10:32:15] <APlayer> No, it's
correct
L500[10:32:28] <Mathuin> "semi"
means half, does it not?
L501[10:32:38] <APlayer> (AP + radius) *
2
L502[10:32:42] <Mathuin> The entire axis

circularization is a win.

L616[12:12:58] <Mathuin> I am not

L621[12:17:12] <Mathuin> I haven't looked

L622[12:17:36] <Mathuin> If Val had waited
for me to get a Terrier engine, she'd've been able to come
home.
L623[12:17:58] <lordcirth> Mathuin, is she
stuck in orbit or what?
L624[12:18:02] <Mathuin> Stuck for
now.
L625[12:18:10] <Mathuin> I was going to
revert but KSP crashed so I sucked it up.
L626[12:18:59] <lordcirth> Mathuin, how
high is Pe? Close enough to 70k to get out and push, or spin
decouple?
L627[12:19:23] <Mathuin> 85k, not worth
it, will rescue her as a project in writing a rendezvous script, or
restart at worst.
L628[12:19:40] <Mathuin> Jeb ascended with
the gravity turn script, circularlized with the circularize script
and execute node script, and will now hopefully land. I built the
node by hand this time, used the execute node script to execute the
node, and now I'll fly "by hand" for the landing.
L629[12:21:05] <Mathuin> I didn't think to
write a script for landing. :-)
L630[12:22:08] <Mathuin> A variant of the
circularize script would create a node with a desired periapsis,
say 0. Execute the node, and have the ship drop everything to the
heat shield before pointing backwards. I guess?
L631[12:22:32] <lordcirth>
"landing" a capsule is usually just lock steering to
retrograde. wait until alt < 5000. stage.

L801[14:22:24] <Mathuin> ve2dmn: not
complaining at all!
L802[14:22:24] <madmerlyn> so it'll be in
a for loop like for item in EngineList
L803[14:22:47] <Mathuin> "Tried to
push Infinity into the stack."
L804[14:23:01] <ve2dmn> ^ my nemesis
L806[14:23:29] <madmerlyn> you can take
the UNTIL false bit out though
L807[14:23:56] <ve2dmn> I have all sorts
of MAX( funtion(), 0.01) in my code because of the dreaded infinity
push
L808[14:24:21] <Mathuin> My nemesis is the
stupid terminal not preventing other mods from grabbing
keystrokes.
L809[14:24:26] <madmerlyn> I think mine
was along lines of IF item:FLAMEOUT=True AND
item:THROTTLELOCK=True{STAGE.}
L810[14:24:45] <madmerlyn> I did the
throttlelock so it would only stage SRBs since they can't be
throttled outside of VAB
L811[14:24:51] <Mathuin> I have to type
and delete yp when launching, to disable TCA and
AtmosphericAutopilot, because
'runpath("gravityturn.ws").' includes yp
L812[14:24:51] <ve2dmn> Mathuin: use
telnet? it helps with copy-paste too :D
L813[14:25:13] <Mathuin> ve2dmn: what I
really want is a working kOS Prop Monitor.
L814[14:25:18] <madmerlyn> in theory you
could write a whole python script for kOS using expects in
telnet
L815[14:25:21] <Mathuin> The current
prerelease is buggy.
L816[14:26:23] <madmerlyn> you could also
maybe do IF item:FLAMEOUT=True AND item:FUELFLOW=0
L817[14:26:45] <madmerlyn> that way even a
liquid stage would trigger it when it drained if it's not
piped
L818[14:27:04] <Mathuin> The docs have a
good staging exmaple.

L849[14:36:35] <Mathuin> madmerlyn: I have
been brainstorming in this channel on kOS for the past two days.
:-)
L850[14:36:43] <ve2dmn> Aplayer would want
to be in on this :D
L851[14:36:55] <Mathuin> And APlayer has
indeed participated.
L852[14:37:08] <EricPoehlsen> I think I'll
put them on github once they are more than just some ascent
auto-path
L853[14:37:24] <ve2dmn> I'm a sysadmin,
not a dev... so I make crappy mistakes for lack of better coding
practice.
L854[14:37:44] <madmerlyn> I'm trying to
transition to developing
L855[14:37:46] <Mathuin> I'm doing more
devvy stuff, since most of the sysadmin work isn't very interesting
lately.
L856[14:38:05] <Mathuin> Okay, gravityturn
and circularization are sane. landing's next.
L857[14:38:23] <ve2dmn> Mathuin: we are
moving towards DevOps... so I'm gonna have to adapt
L858[14:38:26] <madmerlyn> goooood luck
buddy
L859[14:38:44] <madmerlyn> I spent like 5
hours landing on the launchpad, and while I was ultimately
successful, wasn't very cost effective heh
L860[14:39:00] <Mathuin> My definition of
landing is Jeb walks away. :-)
L861[14:39:19] <ve2dmn> madmerlyn: I would
not know where to start doing that... because I cannot even
guestimate the air loss
L862[14:39:45] <EricPoehlsen> that reminds
me I wanted to calculate the possibility of accidently landing at
KSC
L863[14:40:17] <madmerlyn> if you have a
mod that has grid-fins it helps
L864[14:40:24] <madmerlyn> and
trajectories of course
L865[14:40:32] <madmerlyn> kOS has hooks
for trajectories
L866[14:40:39] <ve2dmn> madmerlyn: I did
not know that
L867[14:40:45] <EricPoehlsen> because some
days ago I had some mishap in getting a space-station into orbit -
or better something exploded on decoupling and I nearly lost
Jeb
L868[14:41:07] <EricPoehlsen> but somehow
I managed to deorbit his capsule with the rcs
L869[14:41:29] <EricPoehlsen> and
miraculously ended up 50 meters from the launchpad
L870[14:41:49] <madmerlyn> I want to kOS
autopilot a landing on the KSC runway, but I'm not sure how to
solve it programmatically yet
L871[14:42:05] <madmerlyn> I'm just
getting to the point where I can do it consistently the same way
manually
L872[14:42:13] <ve2dmn> EricPoehlsen: if
you are in 0 inclination, take the size of the KSC and divided by
the circumference of Kerbin
L873[14:42:50] <madmerlyn> there's still
going to be some inaccuracy though because even the best kOS script
isn't going to get in an absolute perfect 0 inclination
L874[14:43:05] <madmerlyn> mine usually
ends up in like 0.04+ inclination
L875[14:43:14] <EricPoehlsen> ve2dmn: I
thought it will probably be somewhere inside the 1:10000 range
+-
L876[14:43:19] <ve2dmn> I want an
auto-dock
L877[14:43:40] <ve2dmn> so I can automate
supply runs to my Kerbin space station
L878[14:43:53] <madmerlyn> I wonder if kOS
has hooks for docking port alignment, not that that's required but
it might simplify the math
L879[14:44:17] <EricPoehlsen> 1km is
roughly 1:2000 of the circumference
L880[14:44:50] <madmerlyn> Kerbin is only
2000km around the equator? Surely it's bigger than that.
L881[14:45:10] <EricPoehlsen> double
that
L882[14:45:20] <EricPoehlsen> 600 km
radius not 300km radius
L883[14:45:21] <ve2dmn> most of my brain
power has been spent trying to come up with clevers ways to launch
with minimal dV
L885[14:45:35] <madmerlyn> yay a
script
L886[14:45:55] <ve2dmn> madmerlyn: I have

L887[14:46:22] <ve2dmn> Like I said, I'm
no coder... but the thing gets into orbit.... sometimes
L888[14:46:58] <madmerlyn> when I get home
I'll share my spaceplane script
L889[14:47:09] <ve2dmn> That script try to
estimate the loss due to everything... then it forget about it and
simply uses the current groundspeed
L890[14:47:22] <madmerlyn> though it's
less calculating ideal ascent and more, ascend the same way every
time you run it heh

adjusting should be a PIDLoop
L893[14:48:16] <ve2dmn> right now it's...
commented out
L894[14:49:00] <madmerlyn> mine spaceplane
ascent is more along the lines, when you're going 120m/s pitch 10
degrees, when you're at XX altitude do this, kinda deal
L895[14:49:33] <madmerlyn> with a fun
little parameter that can be set to use nose-thrusters to lift the
nose up on my mk2 planes that have the landing gear too far back to
pivot
L896[14:50:18] <madmerlyn> my Lancelot Mk2
plane I just don't feel comfortable moving the landing gear
forward, and since KSP doesn't have multi-position landing gear, my
solution was to add some separatrons to the nose :P
L897[14:50:39] <ve2dmn> right now the
current acent logic I have is :minmum between
L898[14:50:40] <ve2dmn> SpeedPitch TO
(100-(GROUNDSPEED/12)).
L899[14:50:40] <ve2dmn> LOCK AltitudePitch
TO (90 - ((SHIP:Altitude /60000 )*90)).
L900[14:51:02] <ve2dmn> that gives you a
value between 0 and 90 degree
L901[14:51:03] <Mathuin> I haven't
bothered adjusting pitch with the gravity turn after the initial
nudge.
L902[14:51:28] <madmerlyn> my vertical
rocket script just does 0.2 pitch adjustments every 0.2s
L903[14:51:33] <madmerlyn> until it
reaches a pitch of 1
L904[14:51:51] <Mathuin> I dodged the
mid-node staging issue by dropping the launch TWR and it turns out
to be more efficient at the end of the day.
L905[14:51:58] <madmerlyn> hardly fine
tunes itself for a proper ascent though, I pretty much have to
design the rocket around the script
L906[14:52:41] <ve2dmn> I'm trying to
design a good-enough universal script
L907[14:52:50] <madmerlyn> my spaceplane
script is a lot more versatile though, it's worked on every plane
I've loaded it on
L908[14:53:17] <madmerlyn> course I don't
have many spaceplanes that are really low TWR so that probably
helps
L909[14:53:41] <ve2dmn> I'm really bad
with spaceplanes, so I don't bother
L910[14:54:37] <madmerlyn> did you look at

L919[14:58:21] <madmerlyn> all the planes
labeled Gallahad have the same wing configuration, just in
different payload capacities and cargo configurations
L921[14:58:59] <madmerlyn> Gallahad-L and
LC are the "Lite" versions that are only rated around 20t
cargo and have a slightly shorter cargo bay, the standard Gallahad
can do 55t of cargo with a longer bay
L922[14:59:23] <madmerlyn> that a re-entry
shot?
L923[14:59:43] <madmerlyn> for re-entry I
use a descent profile in trajectories of 47/42/37
L924[14:59:55] <madmerlyn> basically I
stay close to 40-45 degrees until I go completely subsonic
L925[15:00:01] <madmerlyn> then I push my
nose down and drop altitude
L926[15:00:31] <ve2dmn> I also have one of
a burning cross, because my Eve sat was designed as an X of sats on
top a long line of fuel tanks...
L927[15:00:37] <madmerlyn> trying to hold
45 degree pitch will give you a good indication if you need to
balance your fuel a bit too
L928[15:00:39] <ve2dmn> not a volontary
image
L929[15:01:00] <madmerlyn> if your nose
keeps pulling down pump full back, if it keeps pushing up pump fuel
forward
L930[15:01:17] <madmerlyn> once you have
good control authority for keeping your nose around 45 degrees
you're balanced enough to land
L931[15:01:29] <ve2dmn> madmerlyn: I'm not
even that design would work these days
L932[15:02:02] <ve2dmn> I'll try you

L935[15:03:12] <ve2dmn> I don't have

L936[15:03:30] <Mathuin> I was playing KSP
and CivV because the wife takes too long with her turns.
L937[15:03:41] <madmerlyn> ve2dmn when I
started redeveloping on the Gallahad class I was using SpaceY
nosecones, but I made pure stock variants for KerbalX
L938[15:04:07] <ve2dmn> Mathuin: you have
a wife that plays Civ5 ? lucky you. None of my friends do :/
L939[15:04:13] <madmerlyn> then I
discovered that in spite of the 2.5m nosecone having low skin
temperature and low mass, it performed very well in the normal 100%
heating or whatever default is
L940[15:04:36] <Mathuin> ve2dmn: my wife
plays just about as well as me -- I'm superior in combat, she's
more of a diplomat -- and she really likes playing.
L941[15:04:39] <madmerlyn> so now I
primarily just use my stock versions
L943[15:05:04] <madmerlyn> they both have
similar dv on orbit and everything so I don't really gain much by
using the SpaceY nose except a color scheme that clashes with the
rest of the ship
L944[15:05:35] <madmerlyn> only 1 KAC? I
wish I could keep my space program that focused. lol
L945[15:05:47] <madmerlyn> I'm down to 3

L947[15:06:26] <Mathuin> It's raining
Kerbals.
L948[15:06:37] <madmerlyn> I've been
stalled out last couple playsessions trying to figure out how I
want to do my Spartan VI mission to Eeloo
L949[15:07:08] <madmerlyn> first one was
going to use NFP Hall-Effect thrusters, but then I realized the
burns would be like 20m long
L951[15:07:52] <madmerlyn> then I switched
to a monoP OM engine from NFP, but it was too wide to fit in my
plane so I had to develop a proper lifter for it
L952[15:08:16] <madmerlyn> ve2dmn you just
gotta approach correctly
L953[15:08:37] <madmerlyn> when I started
aiming my initial trajectory at the mountains instead of the KSC
landing became so much easier
L954[15:08:42] <ve2dmn> Mathuin: on that
screenshot, everytime I would eject the kerbal, it would simply
create a new zombie one...
L955[15:08:52] <madmerlyn> I aim my
deorbit burn so trajectories puts its X on the mountains
L956[15:09:04] <madmerlyn> do my 37-47
degree pitch until I'm subsonic
L957[15:09:19] <madmerlyn> which usually
puts me right above the mountains at around 17-20km altitude
L958[15:09:50] <madmerlyn> then I push my
nose down and descend, usually doing 40 degrees below horizon until
I get under 10km then bringing it up to eventually 10 degrees below
horizon until I get down to 2km
L959[15:10:10] <madmerlyn> and then just
gradually level out until I'm approaching the runway below
200m
L960[15:10:11] <Mathuin> Is there an
interrupt key for kOS? Stop what's running and bring me back to a

learned about kuniverse:reverttolaunch()...
L965[15:11:09] <madmerlyn> my bigger

anymore, I've got my approach down so well I'm usually gliding in

L980[15:15:59] <madmerlyn> another thing
looking at the launch scripts, consider parameters for your target
altitude, that way you can just call your script like `run
launch1(150000).` if you want to change your target altitude
without editing the script
L981[15:16:54] <madmerlyn> top of script
just put `parameter orbitHeight is 100000` that way it defaults to
100km if you don't specify the parameter, but you have the option
to put a different number in there if you want to

L984[15:19:02] <Mathuin> In retrospect,
storing a JSON file of settings for ships isn't as good as storing
the information on the ships themselves.
L985[15:19:36] <madmerlyn> lol
serialization for serialization's sake is not always good no
:P
L986[15:20:01] <Mathuin> It's not for
serialization's sake, it's a way of storing parameters so I don't
have to modify the script, much as you said.
L987[15:20:04] <madmerlyn> really only
reason to serialize in something like kOS is if you're trying to do
some machine learning or something
L988[15:20:07] <Mathuin> If I could store
them _in_ the rocket...
L989[15:21:02] <madmerlyn> just identify
things you might want to change on different types of launch
scenarios and convert them into variables that are passed through
parameters
L990[15:21:34] <madmerlyn> it'd be nice if
kOS had a way of building terminal menus, but parameters work well
enough in absence of that
L991[15:22:06] <Mathuin> madmerlyn: that's
part of why I want kOS Prop Monitor to work.
L992[15:22:12] <madmerlyn> I thought it'd

KAC alarm
L1064[16:07:31] <ve2dmn> And by crossing
I mean <70km
L1065[16:08:16] <madmerlyn> how do you
handle circularization? my script points at -1 pitch and switches
between -1 and +6 to maintain apo until it's finished
L1066[16:08:42] <ve2dmn> I was trying to
add a relevant contract available... either by spawning an asteroid
with the relevant orbit or give a premade-contract that give you
the next found asteroid as an objective

hwo to get stuff to fit the cargo bay and still wheel out on its

L1078[16:11:41] <madmerlyn> Gallahad-L

L1079[16:11:58] <madmerlyn> can do at

L1103[16:20:07] <madmerlyn> well the
problem with mk3 planes is they tend to have very heavy noses and
be long, so you need good control surfaces in the front
L1104[16:20:21] <madmerlyn> I couldn't
make a canard that looked better with other stock wings
L1105[16:20:32] <madmerlyn> not that had
enough lift to get that monster off the ground anyway
L1106[16:21:07] <madmerlyn> 55t on the
full size, can probably do more that's just the biggest payload
I've taken
L1107[16:21:23] <madmerlyn> AND it does
55t to orbit with at least 600dv left for maneuvering + deorbit
burn
L1108[16:21:43] <madmerlyn> and it flies
well enough you can glide it back to runway without powering up the

could use your approach to do space tourism on the cheap
L1113[16:23:21] <madmerlyn> that was the
flight that made me think up using "landing assist gears"
on the tail to prevent tailstrikes
L1114[16:23:32] <umaxtu> didn't Concorde
do that?
L1115[16:24:04] <madmerlyn> maybe? I know
most commercial liners have multiposition gear to accommodate
needing to pivot on takeoff and preventing tailstrikes on
landing
L1116[16:24:05] <JCB> ya.. it had a pair
of little 'roller skate' type wheels near the tail
L1117[16:24:44] <JCB> a number of

out of russia that has a retractable wheel skid
L1118[16:26:05] <umaxtu> it sure was a

due to drag, and loses due to gravity
L1281[18:36:59] <ve2dmn> if it was

you minimise dV?

enough thrust to get me up and pointed in the right direction
(tweaking TWR in my code) and choosing the right angle/speed

L1411[21:53:00] <madmerlyn> well yeah in
reality canards create turbulence on the wings behind them
etc.
L1412[21:53:21] <madmerlyn> in KSP they
don't so that's why they work *so* well, according to this guy

L1427[22:22:35] <ve2dmn> Except I used a

L1428[22:22:38] <madmerlyn> way too much
engine power too hehe
L1429[22:22:44] <madmerlyn> like it could
probably work with 2 engines
L1430[22:25:05] <madmerlyn> so my new
revisions with the 36 kerbal capacity LC-XL Gallahad
L1431[22:25:27] <madmerlyn> if you refuel
it on orbit with just a little bit of fuel
L1432[22:25:32] <madmerlyn> could go to
Mun or Minmus orbit
L1433[22:25:35] <madmerlyn> and
back
L1434[22:25:53] <madmerlyn> could
probably even land on minmus if you're particularly
adventurous
L1435[22:26:57] <ve2dmn> yeah, looking at
your designs and script, it's clear that I made spaceplanes with
not enough engine power
L1436[22:27:30] <ve2dmn> was trying to
save dV but I wind up not being able to make it into orbit
L1437[22:27:58] <madmerlyn> I hate SSTOs
that require complicated ascent profiles :P
L1438[22:28:11] <madmerlyn> if I have to
do a 5km nosedive halfway through it's not a good spaceplane
IMO
L1439[22:28:47] <ve2dmn> It just
confirmed my suspicions :/
L1440[22:29:04] <ve2dmn> now I'll just
have to learn to land properly
L1441[22:29:31] <madmerlyn> since their
purpose is to recover all the non-fuel costs, I don't fret too much
if having a little more engine power means burning more fuel,
because I'm still getting cost per ton of payload below 1k
L1442[22:29:47] <ve2dmn> basically I try
to aim too high and overdesign... which usually means lacking
