Wing Sweep angle and flight....?

[Kilo_60]

Does this game simulate aerodynamics of wing sweep angles?

Is a more aggressing rearward sweep help to decrease wing drag and help with supersonic flight?

Do forward swept wings create more manuverablility and add to drag...

[Venusgate]

Only in the sense that a swept wing has a lower cross-section per lift than a straight wing. Swept designs will achieve greater speeds only by virtue of there being less drag per lift.

No vortices action to be concerned about either, unless you believe it is a minion of the kraken

in stock KSP it doesn't matter how you place your wings as long as they are paralel to the ground. Drag is set in config file and basically depends only on wing area. Rotate slim wings and they won't change anything for drag. Shear wings and delta wings have the same drag straight ones have in the same size (MK3 wings with fuel are much thicker for example).
There is accurate aerodynamic force data available with Alt+F12.

Basically length of the objects is as important as their width. It's kind of frictional, surface drag oriented. Probably for the same reason ramp intakes have 1.5x the drag of shock cone intakes - they are just longer.
For this very reason you can't trust F11 much either. Depending on you having one long tank or 4 short in MK3 spaceplane for example you may see huge red line miles behind or almost none. The drag will still be the same though, just as 4 shorter vectors.
