modifiy Drag coefficent of Parachutes

[Voidi]

Hello Guys

Original I want a little nice drogue-parachute that can be mounted radial. Because I didn't find an existing part, I decide to try make my own one.

How hard can modding be anyway?

To start, I copy the Mk2-R Radial-Mount Parachute and change the values in the part.cfg. I thought for a first step this should be ok, after that I could change texture.

But then I realised the chute opens at a high of 2500 m as configurated, but seems to have drag like a normal Mk2-R. I googled a bit and found that (at the moment?) the drag of a parachute is calculated 'mass x drag coefficent'.

My first question is how to modify the drag coefficent to get a behaviour like a drogue chute?

Secondly after the update I want to play with Ferram Aerospace Research (again).

What should I consider that FAR calculates my chute correctly?

The aerodynamics of FAR are really great, are there any plans to integrate this in the vanilla game?

Greetings Voidi

I guess that you are using ModuleParachut? Then you should look what features this Module has to offer. Open the Assembly-CSharp.dll in e.g. Visual Studios Object Browser and search for ModulePara. Now you should be able to select this class, see what methods / fields it has to offer and play around with them. "public float parachuteDrag;" looks interesting, for example.

If you cant get your wanted behavior via this stuff you have to write your own PartModule... what would be somewhat more complicated.

Never used or had a look into FAR, yet.

Ok tested some things with part.cfg.

How can i modify this "public float parachuteDrag;" is it possible from the part.cfg?

A hack to simulate a lower drag is to reduce the mass.

Writing 'maximum_drag' to part.cfg as described http://wiki.kerbalspaceprogram.com/wiki/CFG_File_Documentation#Standard_Part_Parameters:

seemed to has no effect (I tested a value of 0.1)

You need to modify the value inside the MODULE{}

stowedDrag = 0.22
	semiDeployedDrag = 1
	fullyDeployedDrag = 500

Ok my fault! At my first test I looked not serius enough at the values.
