1.0 Aerodynamics

Recommended Posts

These are the same exact settings as in 1.0.0, why don't you open physics.cfg manually? You should see Drag 6.0 DragCubes 0.06 Lift 0.038 and Bodylift 8.

If you do see those, the problem is a mod. If you don't see those, then this OP isn't right.

Here's the top of my physics.cfg:

dragMultiplier = 6.0dragCubeMultiplier = 0.06
angularDragMultiplier = 2
liftMultiplier = 0.038
liftDragMultiplier = 0.03
bodyLiftMultiplier = 8
aeroFXStartThermalFX = 2
aeroFXFullThermalFX = 3.5
aeroFXExponent = 3
thermalMaxIntegrationWarp = 100
spaceTemperature = 4
solarLuminosityAtHome = 1360
solarInsolationAtHome = 0.15
convectionDensityExponent = 1

Worse comes to worse, just change the altitude the chute deploys fully at by right clicking it in the VAB. Anything in the lower atmosphere should be relatively safe. Actually can stock chutes even snap in the first place?

They can burn up in the atmosphere given a steep enough reentry...

Hows your experience with that?

I did, something else is wrong.

I verified the files, opened up the game and tested it, no problem. Applied someone else's suggested changes and launched a mission, same problem.

It must be another mod, but I'm not sure which one. Here's my modlist

http://i.imgur.com/sHUUScH.png

I'll probably just wait until Squad fixes the aero and the rest of the mods update.

Hey, I uploaded the wrong file by a mistake. Now the download is fixed, please redownload the file.

I did something similar, kind a rough half-way between the two. Gonna try it out, might not be too bad.

dragMultiplier = 7.0

dragCubeMultiplier = 0.08

liftMultiplier = 0.042

liftDragMultiplier = 0.028

bodyLiftMultiplier = 9

Anyone who tryed this out have you experienced parachutes being needed to deployed earlier? I did a simple slest on just a mk1 pod and mk16 parachute, it seems if you let it fully deploy at the default altitude, 500m, there isn't enough time for it to slow you down from your terminal velocity to a safe landing speed. Tried upping the altitude for its deployment and seems that doing it at 2000m is good, I also noticed that the landing speed with parachutes has increased, I'm getting 8/ms around about now, where before I used this mod to restore the superior 1.0 aerodynamics, in 1.2.0 landing speed was about 5.6/ms with the same set up. I know its not a deadly landing by any means, but with this mod changing the aerodynamics back, and squads recent parachute hotfix, it seems you have to be more careful when to deploy parachute. Before it was just like, "lol I'm 500 m up! Better pop dat chute! *slows from 200+ m/s to 5m/s in a matter of seconds* ... Yay!" Now it seems more realistic perhaps? I though ksp parachutes were a bit too powerful anyway.

Its working fine with my setup... didn't test it with 1.0.0 cfg...

i semi-deploy the chutes between 4 and 10km, full deploy at 500m altitude, they need about another 250m to slow down

Yeah how do you give rep? I think you deserve some!

Description

So, 1.01-1.02 rebalanced the aerodynamics quite a bit. The atmosphere is not soupy compared to 0.90 but it is in comparison to 1.0. It made SSTOs harder, rockets harder and most importantly it broke my stock Ranger which now can't aileron roll at all. So I've modified Physics.cfg to the 1.0 values. The original file was made by Squad, I take no credit for it, I've just modified some values.

Great idea!

I would love to find out if this is something ModuleManager could do -- then custom profiles for aero can be built. I imagine this is how FAR does/did it. I'd love to not mess with the stock files. :D

Ask, and ye shall receive from Sarbian (technically, received before asked). And no, that's not how FAR does it, FAR disables stock aero completely rather than changing values.

That's totally great -- Now I'm going to try my hand at a quick MM patch / playground for fiddling with the aero values.

I took a simple stab at this:

@PHYSICSGLOBALS
{
@fullConvectionAreaMin = -0.2

// Compromise
@dragMultiplier = 7.0
@dragCubeMultiplier = 0.08
@liftMultiplier = 0.042
@liftDragMultiplier = 0.028
@bodyLiftMultiplier = 9


// KSP 1.0
//@dragMultiplier = 6.0
//@dragCubeMultiplier = 0.06
//@liftMultiplier = 0.038
//@liftDragMultiplier = 0.03
//@bodyLiftMultiplier = 8

// KSP 1.0.1&2 (Current defaults)
//@dragMultiplier = 8.0
//@dragCubeMultiplier = 0.1
//@liftMultiplier = 0.055
//@liftDragMultiplier = 0.025
//@bodyLiftMultiplier = 10.7
}

First MM patch!

That's awesome! I'd rather MM patch than hard replace a file.

Quick question though, what does 'fullConvectionAreaMin' modify?

Oh, good question. It was a change suggested by NathanKell. Maybe it needs a .cfg file all its own to keep from confusing it with the aero settings (or maybe it made it into the stock bugfixes by now).

This mod dead now that nuFAR is out. There is no point for it anymore.

Oh, that white text got me. I was even typing a paragraph asking you to show some respect to the mod author, and all that. :sticktongue:

Glad to hear you have a good sense of humor. I mean no disrespect to the author. Just a joke from another thread hoping to catch someone too headstrong to stop and check the fine print subtlety is so lost in plain text. Everyone has what they enjoy no need for any1 to really go around shouting people down. Fly high!

Not in this case, it's simply sharing a cfg file that was available in older versions.

I've got in trouble for that before. My probe science mod is NOTHING but config files and I got a warning for it. Because it had no license. :)

Ok, so for everyone trying their own ad hoc mix of values, could I possible get a progress report?

I know StainX, Beetlecat and NikoKun have all tried their own values. StainX says it's working great for him, how are the rest of you doing?

I'm just trying to find a bit more of a consensus on what sane values might be. I'm hoping you fellow Kerbonaughts might have found something that actually feels balanced, offering some level of challenge without inducing pure frustration.

So have any of you played around with the values further? Specifically, have you compared the same crafts with different aero values? I'd love to hear about any comparisons you guys may have done regarding parachute effectiveness, rocket thermal deconstruction tendency, approximate dV to orbit, airbrake effectiveness, that kind of thing.

ps. I think we need a new word to represent the "rocket thermal explosiveness" metric.

How about we call them "Pirate-Ninjas"? :wink:
