<egg|coffee|egg> Iskierka: what do you mean? the wide-body fuselage is pretty much what comes with stock, or do you mean the fuel jowls as ferram calls them? or the wing shape?
tfsleep is now known as Technicalfool
<Iskierka> fuel jowls make it look like F-35 fatness?
<egg|coffee|egg> ah, I see what you mean
<egg|coffee|egg> but with tanks instead of intakes
<Iskierka> wing shape has some sensible reason to it if supersonic though I'm not sure if FAR manages to account for it - F-15 has similar clipped wingtips because the area behind the wingtip in the shock cone produces half lift while supersonic, so is inefficient
<Iskierka> so when needing a larger wing area in limited wingspan, extend backwards with clipped tips
<egg|coffee|egg> Iskierka: the jowls are here both because I need fuel and for area ruling, which FAR does account for; not sure about the clippy tips (though they help area ruling too)
<Iskierka> I think the increased area is probably more harmful than area ruling gains
<egg|coffee|egg> Iskierka: and yeah, this is very much supersonic, gets to Kerbin's pole from KSC in a quarter of an hour
<egg|coffee|egg> so Mach 3.6ish
<egg|coffee|egg> (those are 4 J58s)
<egg|coffee|egg> (that engine is magic)
egg|coffee|egg is now known as egg
<egg> my coffee is empty
<Iskierka> area ruling is more about smoothing out when you have to have a big area change in short distance due to other constraints, otherwise, thinner is preferred. Concorde doesn't significantly area rule in that way because the wing's area increase is smooth enough
<egg> Iskierka: yeah, there's this pretty graph http://i1080.photobucket.com/albums/j326/clivel1/Image44.jpg
<egg> Iskierka: though you don't really have this flexibility in wing shape or fuselage shape in KSP
<egg> it's pretty much double-delta at best and warts on the stock fuselages :-p
* Iskierka tries to figure out which of the dozen javascript sources photobucket wants to use will load the image
<egg> oh gosh
<Iskierka> there we go
<Iskierka> and yes, good example, body is a constant area below the wing because it's just smoothly constructed
<egg> yeah
<egg> Iskierka: though in my case I also needed to shove fuel somewhere; I guess I could have lengthened the fuselage for that, but that can also pose problems, right?
<Iskierka> http://i.imgur.com/815r0k4.png and you can get pretty smooth if you use a fair few pwings (and take measurements of concorde's wing and match them)
<Iskierka> I just have wet wings and usually have a fuel body since I'm doing SSTO
<Iskierka> not tried to carry lots of kerbals really
<egg> cute aircraft
<egg> what's that cockpit?
<egg> Iskierka: btw, ferram4 was wondering if the effect of the spiky bit at the end (antenna here) was amplified as a model artifact, or correct
<Iskierka> it's a drone from one of the aircraft expansions. Possible Mk2 expansion?
<Iskierka> ?
<egg> Iskierka: putting an extended antenna pointing forward on the nose significantly improves wave drag area
<egg> this apparently stays true if you reduce voxel size, so not a discretization artifact
<egg> Iskierka: yeah, the question was whether the amplitude of the effect was correct
<Iskierka> basically supercavitation for compressible fluid vehicles
<Iskierka> no idea :p
<Iskierka> although it states estimated to increase the range of trident I by 550 km. There's a possible test case if you can model a trident and get some reasonable test guidance going
<egg> Iskierka: btw, icymi, this is a thing https://logs.tmsp.io
<Iskierka> fun, but I do now have a bouncer that keeps logs from when I last logged in, and my own logs :p
* UmbralRaptor pokes spectra with a stick.
* UmbralRaptor is reasonably certain that the roughly V-band magnitude (4000-6500 Angstroms in this case) of a 5800 K star sized at 1 solar radius and 10 pc away should be about 4.8
<UmbralRaptor> But I get 5.7 to 5.9, depending on conversion details. o_O
<egg> UmbralRaptor: what's that thing about pascals and radians
<UmbralRaptor> Okay, the only sane flux unit with a specific name is the Jansky.
<UmbralRaptor> It works in ergs per square centimeter per hertz.
<egg> UmbralRaptor: but whence the argle
<egg> angle
<UmbralRaptor> Angle is sometimes needed if you're considering the emitting source, and where it's emitting.
<egg> UmbralRaptor: not solid angle?
<egg> though anyway 1 sr = 1 rad ** 2
<UmbralRaptor> Ack.
<UmbralRaptor> Yeah, probably
<UmbralRaptor> But for the unit shenanigans, flux is more commonly ergs/cm^2/s/Angstrom in the optical.
<UmbralRaptor> Converting to MKS: W/m^3, and as energy density is pressure.... >_>
<UmbralRaptor> And yet ergs/cm^2/s/A is better than magnitudes. o_O
<egg> UmbralRaptor: I don't have the spectral quantities
<egg> UmbralRaptor: ... I guess you could have template<typename T> using Spectral = Quotient<T, Length>
<egg> UmbralRaptor: though you'd need a different word for Quotient<T, Frequency>
* UmbralRaptor wonders if this means one will be able to do photometery in Principia. o_O
<egg> UmbralRaptor: now you know what to do when you're done with the kozai test

<egg> Norgg: eventually we'll update principia >_>
<egg> any century now <_<
<Norgg> Whee, when was the last update?
<Norgg> How's KSP going in general? Not been following it for a while.
<Norgg> I think last I was paying attention half the dev team had quit. :P
<egg> Norgg: pretty much :D
<egg> now they're working on i18n I think? so hopefully they won't break what I'm working on by doing that
<egg> I'd assume there's going to be less breaking changes with the disparition of the dev team
<egg> Norgg: so, as for how principia is going, the last released version is still Cantor, for 1.1.3 (hopefully despite the name that won't hold for an infinite time)

<ferram4> Yeah, FAR doesn't handle the loss in lift. That's kind of difficult.
<egg> ferram4: I mostly went with that shape for area ruling tbh
<ferram4> Yeah, it helps
<ferram4> At least with that.

* Qboid gives pizzaoverhead a silly µa741/induction hybrid
<Iskierka> induction makes a poor noun
<egg> Iskierka: made a thinner plane following your advice (also half the capacity & half the engines of the other one); it supercruises ~10% slower, but otherwise seems to have good range http://imgur.com/a/3IYu1
<GreeningGalaxy> I don't understand how that's controllable without foreplanes
<GreeningGalaxy> I mean, I realize that it is; I've seen the Concorde... I just don't really get it.
<egg> surprisingly, contrary to the Concorde (and many other KSP planes I make) it doesn't require fuel pumping for balance
<egg> aaand here's the ice shelf
<egg> over the horizon at 14ish min, comparable to the other one
<egg> mostly because it's more manoeuvrable, so I didn't spend ages turning north after liftoff
<egg> let's see if it lands
<egg> subsonic
<egg> ack not enough pitch authority
