I still have a little ol' heli I made with firespitter mod
pthag has joined #KSPOfficial
<JVFoxy>
suppose I could try making a heli in KSP, would have to download latest..
<JVFoxy>
make for interesting mountain biome gathering
<Althego>
i suggest tilting jets, you are better off
* JVFoxy
pokes the website, "ok.. interesting, can download older versions. nice"
<JVFoxy>
Althego: lol.. tilting? I used to fly with two mk1 command pods back to back with a RT fuel tank in the middle. and 6 juno jet kits all around. RW for control..

moves like snot... just gotta be careful with landing at high alts
<JVFoxy>
ok.. maybe 'snot' not a good term.. moves pretty frig'n fast
<Althego>
i dont understand why i get a roll from a coaxial setup
<JVFoxy>
Althego: rotors clipping into the hub?
<Althego>
they are attached to it
<JVFoxy>
also, not sure if KSP models gyroscopic effects on spinning parts properly. Typically, when you pitch forward in a heli, it tends to want to roll one way because of it
<Althego>
but the electric motors and the blades are really op
<JVFoxy>
Althego: clipping.. as in when the hub is spinning, does it look like the blades aren't keeping up and mash into it?
<Althego>
no, not really
<JVFoxy>
I was watching shadowzone's video on the new parts.. they were having issues as well. Its like the parts weren't properly attached and bending
<Althego>
but doesnt matter i actually want to make a folded wing airplane with electric props
<Althego>
since watching that video i realized there is a mirroed variant for the blades
<JVFoxy>
I'mma try a heli myself, see what I can come up with. My firespitter one was pretty nice flying, looked good. Simple build but, was somewhat restricted on things at the time
<Althego>
aha, i think i know why. the direction of the yellow arrows flips on one side
<Althego>
that causes a roll
<JVFoxy>
yellow arrows?
<Althego>
yellow arrow is control surface lift
<Althego>
and apparently rotors are rendered as such
<Althego>
no, wait, rotor is purple and it also has yellow
<Althego>
may be the lift difference in airflow
<Althego>
still shouldnt matter for a coaxial
<JVFoxy>
depends... forward movement, lower rotor will have higher lift on one side, upper rottor opposite. Tends to cause a slight imbalance
<Althego>
yes, looks like it is because of the asymmetry of lift
<Althego>
but still, it should be the same for both rotors and cancel out
<JVFoxy>
gah..! so used to running KSP without music. Finally loads and blame audio
<JVFoxy>
*blam
<Althego>
maybe they dont have the exact angles
<JVFoxy>
are you rotors side by side or on top of each ohter?
<Althego>
so this failed too
<Althego>
we really need a collective :)
<JVFoxy>
ok finally got in game...
<JVFoxy>
see what we got going on here..
<Althego>
actually you can couple the electric motors to throttle
<Althego>
so it is kind of ok
<JVFoxy>
lol.. kill ambience sound in SPH... wanna music instead
<Althego>
although in realyt it was probably the small wings that helped, autorotation probably not simulated
<JVFoxy>
oh wait.. is rotors an expansion thing?
<Althego>
breaking grounds
<Althego>
or whatever it is called
<Althego>
now i am patiently waiting for my submarine parts :)
<Althego>
the props should work in water too
<Althego>
juts as jets do
<JVFoxy>
ok.. n/m then. I never got either expansion. :\
<JVFoxy>
ya.. I fail.. eh..

i think i know what the problem with the helicopter was, at least partially. that couldnt cause a roll, but for a coutner rotating blade, you need to change motor direction, blade variant and deploy angle

i wonder what happens to kerbals when the blades hit them
<Althego>
danny is probably already making a video about that
<Rolf>
lol
<Rolf>
he will also somehow make it shatter world also
<Rolf>
his earlier world breaker was using kerbals and 2 claws after all
<Althego>
the problem is i cant use brakes and also let the props running
<Althego>
but i can builda test craft for this
<packbart>
Murphy's Law is unconstitutional.
<packbart>
Althego: you could set the rotor brake force to 0
<Rolf>
dont... tempt Murphy
<Althego>
doesnt help
<Rolf>
set it to -10 :P
<Rolf>
wonder if its possible by editing files
<packbart>
so, the recent SmokeScreen update is throwing NREs. I might just get rid of RealPlume and go back to stock exhaust

the helmet protects against blade impact
<JVFoxy>
well kinda makes sense
<JVFoxy>
you've seen them fall on their heads and not a scratch
<Rolf>
the helmet own all
<Rolf>
jv theres video where one kerbal deorbited and landed without any ship
<Rolf>
trick was to land on helmet first, then butt
<Rolf>
and it was hard trick, guy retried bunch times

From LKO, it's easy. I did that a few times now to pilots to be rescued ;)
<packbart>
Look retrograde to the horizon, burn the jetpack down to ~0.3 fuel, then turn sideways and punch through the atmosphere, turn into the wind after the firewarks and deploy chute
<Rolf>
they have crutes now?
<Althego>
but only from 3 stars
<Rolf>
video was pretty old. and it was... lathobrake not water or crute
<packbart>
no-star pilots have chutes from the beginning
<Althego>
hmm

apparently the props are not so happy on duna
<taniwha>
I can't imagine why
<Althego>
they prduce 0 thrust
<taniwha>
they produce 0 thrust on Kerbin, too
<Rolf>
eve?
<taniwha>
they use lift, not thrust :)
<Rolf>
lol
<taniwha>
(but if they actually don't work on duna, that's a problem)
<Althego>
maybe changeing the blade angles would help
<Althego>
but that is probably not simulated
<taniwha>
they're lift surfaces
<taniwha>
it might well be that duna's air is too thin
<Rolf>
thats what made me wonder how well it would work on eve
<Althego>
it wasnt too thin to glide
JVFoxy has quit [Quit: Leaving]
<Althego>
we know they work in eve
<Althego>
see matt lowne
<Rolf>
lol ok
<taniwha>
Althego: wings are generally a darn sight larger than prop blades
<Althego>
they also move with different speeds
<Althego>
8300 m on kerbin, still climbing
<Althego>
highly visible forces on the blades
<taniwha>
what's the air density?
<Althego>
i forgot to pack a science instrument
<taniwha>
aero gui
<taniwha>
(think it's in alt-f12)
<taniwha>
and I /think/ it has density
<Althego>
static pressure 24.5 kpascal, density 0.37 kg/m^3
<Althego>
went up to around 8800 m
<taniwha>
ok, now compare with Duna
<Althego>
while at around 500 m asl there was 0 force on duna
<Althego>
based on the wiki duna has around 6.75 kPa on sea level, so it means it is indeed too thin
<Althego>
even if it has higher density
<taniwha>
don't trust the wiki
<taniwha>
but yeah, 6.75/24.5 is quite a bit lower
<Althego>
still i expected at least some small thrust
<Althego>
not 0
<Althego>
ok, the arrows may have been just almost zero lenght
<taniwha>
yeah, hard to tell when they're that small
<taniwha>
btw, density ~= P/(RT)
<taniwha>
(depends on molar mass)
<Eddi|zuHause>
if you're using ~= you can drop the R (it's a constant anyway)
<taniwha>
true
<taniwha>
hmm, 4 part ship, 1640 verts?!?
<taniwha>
I guess they add up fast
<Eddi|zuHause>
circles?
<taniwha>
sorry, 5 part (tired)
<taniwha>
3 whip antennas, a pod, and EL's micro pad
<taniwha>
(mk1 lander can)
<taniwha>
so yeah, a few circles
<taniwha>
just surprised it's *that* many
<Eddi|zuHause>
i imagine circles are a pain if you're limited to straight lines
<taniwha>
and it broke my quickhull code :(

i think they messed up the deploy speed of the blades. it is fast in the air, and slow in the hangar
<Althego>
120 kPa, that is probably not supercritical yet
<taniwha>
1.2atm
<taniwha>
oh, I see, yeah
<taniwha>
took me a moment to realise you meant the physical sense
<taniwha>
(I've been fighting with quickhull for two days, so rather tired)
<Althego>
14 km is service ceiling for this thing
<Althego>
can do zoom climbs higher but the max is maybe 14.5 km
<Althego>
now i have to come up with foldable wings that dont make it completely wobbly

the helicopter blades generate qiute a big lift, but they just dont work right, always make the plane uncontrollable

after all these changes with the blades now the left engine doesnt generate thrust anymore. after a while. it startr out ok
<Althego>
seems to be because of speed, in dive the other one stops too, but somewhat later
<Althego>
took down the blades from the attachment nodes and put them on not on the nodes, now they are symmetric
<Althego>
those nodes are useless anyway, they do not change the number of blades even if there are blades on them
