negative air resistance???

[king of nowhere]

I was launching a plane, when i noticed something very strange: negative air resistance

now, i know of a case when you get negative resistance, and that's when you use propellers. i made many things with propellers (it's basically infinite fuel without cheating), and in this case the effect of the propellers is rendered as negative resistance. which incidentally makes it awfully hard to figure out how your plane is doing aerodinamically, but i'm going on a tangent here.

anyway, i'm not using propellers here. this thing has propellers, but at the moment they are safely enclosed inside a cargo bay. they wouldn't be able to work at this speed anyway.

for the sake of science, i tried to shut down the engines; if the resistance is negative, i should keep accelerating without it. but didn't happen, as i shut down the engines i started decelerating. unsurprisingly.

anyone has any idea what the hell just happened with the resistance data?

 

P.S. I was uncertain if i should put this under gameplay questions, but then, this is not a question about gameplay.

That is quite odd! Is AeroGUI a mod? If it is maybe its just a glitch? But if not you could have found one hell of an exploit! A reaction-less, 0 energy input space craft! You should try it again to see if it is reproduceable!

No, it's just the window that pops open if you open the debug menu and go on physics-aerodinamics-show aerodinamic data

alas, as i said, it does not generate actual propulsion. the plane slowed after shutting down the engines

Oh I see, well then I would bet it is just a glitch. Maybe telling a dev would be a good idea, or bringing it to some place that catalogs glitches?

I’m muddling through half-remembered Italian in the screenshot... could the “total resistance’ figure be including thrust? Does the number remain negative if you shut off the engines?

No, it cannot. I normally always get a positive number, even though i am accelerating with rockets. only exception, as i mentioned, is when i accelerate with propellers, because the thrust from propellers is counted as negative resistance. but that's not what's happening here

i didn't check when i shut down the engines - i was more concerned about not screwing up the ascent. but i have plenty of experience of using rockets and getting positive - and high - resistance

hmmmmmmmmm

Really gets your noggin jogging.

Presumably the negative resistance from the propellers in the cargo bay is being enumerated by the game, it just isn't being applied, and the AeroGUI can read and display presently unused values.
