because it was not hard enough to beuil a dyson sphere around a star. no, build it around a black hole

there's no way

<Althego>
oh no
<darsie>
.
* darsie
discovered he can trim his rover to drive forward unattendedly.
<Althego>
btw did you know there is now a separate ground throttle and airplane throttle?
<darsie>
no
<Althego>
the problem was for me, sas is coupled to car forward
<Althego>
so constant sas on-off
<darsie>
Dang, I accidently increased time warp than decreasing an flipped over.
<Althego>
that is why serious people use planes :)
<Althego>
at least now we have the space boat dock in ksp
<Althego>
so you can legit build boats
<Althego>
even if they dont work well
<darsie>
Hmm, maybe I can land a plane in the mountains and scan a huge quartz with an OP-E arm.
<Althego>
that is what i tried once
<Althego>
was total pain
<darsie>
:)
<Althego>
landing is almost impossible
<Althego>
not that rovers like 45 deg slopes
<Althego>
and then even if you landed, you need to get really close to the crystal thing
<Althego>
with a vtol it is probably possible
<Althego>
not with a normal plane
<darsie>
I landed with planes on mountains. Not high inclination, though.
<darsie>
Dunny if my planes are normal :).
<Althego>
yes i did too
<Althego>
on top
<darsie>
mhm
<Althego>
the crystal wasnt there
<darsie>
shh
<darsie>
:)
<darsie>
Hmm, I could search for it with a plane.
<darsie>
and/or drop a rover with a chute.
<darsie>
Electric plane :)
<Althego>
electric eye
<darsie>
It's silly to have the mount points on the motors vertically and the props are horizontally.
<Althego>
why do rockets need those high towers? for example what spacex is building now. why not just dig a hole and sink the rocket in? and if it explodes that also protects the surroundings
<Mat2ch>
Althego: going down is always much more expensive than going up.
<Althego>
interesting i didnt know that
<Mat2ch>
well, think about it. They are near an ocean, so the ground water is probably very low (and probably even salty)
<Mat2ch>
so you dig a hole and have to pump out the water constantly
<Mat2ch>
then you need to reinforce the hole
<Mat2ch>
and where to put the stuff you dig out?
<Mat2ch>
Maybe there's rock underneath it, it's 100 m you wanna dig down.
<Mat2ch>
You have to get rid of that rock.
<Mat2ch>
Colin Furze has dug a tunnel under his shed. Look him up and see how long it takes to dig just a bit down.
<Althego>
i know
<Althego>
not a fan of his, but saw some videos
<Althego>
other problem would be you have to get rid of the exhaust under ground. lead it up to the surface
<Althego>
i guess you cant ever make the hole water proof
<Mat2ch>
Oh, you can
<Mat2ch>
concrete can be built watertight
<Mat2ch>
but you will get rain in.
<Althego>
put a lid on top
<Mat2ch>
now you've got a bunker for an icbm. :D
<Althego>
yes
<Althego>
they could do it
<Althego>
but i didnt take into account they had infinite taxpayer money

!calc 30000/60/24
<Kerbot>
Althego => ~20.83333333333333333333
<Althego>
wait, what
<Mat2ch>
20 days
<Mat2ch>
yes
<Mat2ch>
:P
<Mat2ch>
no, hours
<Mat2ch>
or days?
<Althego>
30000 records, takes 1 minute, so hours days
<Mat2ch>
days.
<Althego>
oh no
<Althego>
20 days
<Althego>
20 days to delete 30k records from the db
<Althego>
but this is an estimate, some records are kept. so it may be only 2 weeks :)
<Althego>
!calc 2/3*300/24
<Kerbot>
Althego => ~8.33333333333333333333
<Althego>
good, may be only more tha na week
<darsie>
Althego: I think rocket exhaust would interfere with the rocket too much in a hole.
<darsie>
Why does my CCW motor with CCW blades produce negative thrust?
<Althego>
heh
<Althego>
complicated
<Althego>
you have 3 things you can invert
<Althego>
the rotation
<Althego>
the blade type
<Althego>
and the deploy angle
<Althego>
and you have to play with all 3 all the time
<darsie>
Hmm, leading blade edge is on the back.
<darsie>
Do I have to set negative deploy angle?
<Althego>
at least that is how i do it
<Althego>
i invert everything until it looks right
<Althego>
as a real prop would
<Althego>
so lower angle of attack on the outside
<Althego>
the leading edge in the right direction
<Althego>
and the angle of attack positive
<Althego>
and for that you have to use the paw of the motor to rotate direction (you can do it two ways), then the prop paw to switch to the other model, and then the deploy direction
<Althego>
incredibly cmplicatd
<Althego>
in an ideal world just selecting mirror symemtry would take care of this
<betelgeuse>
i am in a circular orbit of 200km altitude. how much deltav would i need to raise my apoapsis to 300km? what's the formula for this? a link or search term would do
<Althego>
not much :)
<betelgeuse>
:D
<Althego>
the game calculates it for you if you have maneuver nodes
<betelgeuse>
yeah but i wanna calculate it myself
<Althego>
i think there is something in the wiki
<Althego>
if not, some of scott's old videos had orbital mechanics
<packbart>
yeah, I don't find the explanation on the forum anymore, though. a dev explained that for physics calculation, the blades are longer than their visual appearance
* darsie
found quartz.
<Althego>
lol
<darsie>
what? :)
<Althego>
so the purple is showing the tips or what
<packbart>
looks like it. man, I seem to remember reading an explanation for the colors but don't find it... the Internet is too deep :)
<packbart>
there's a mod to automatically adjust prop angle, too. "Pitch Perfect"
<Althego>
yes, it is kind of hard to fly with two throttles, so i usually fix the angle
<packbart>
the virtual length was a workaround for some limitation in the Unity physics engine
<packbart>
"The propellers, and to a lesser extent the helicopter blades, calculate their velocity/AOA from an artificially offset position. This allows them to act like they're at a higher RPM than they actually are, to get around the PhysX RPM limit, with the consequent effect on AOA, drag, and lift."
