Try having the side windows cracked before opening the sunroof. The effect is due to a pressure differential and nowhere for the air to pass through to.

The helicopter sound goes away if i open a bit the side glass.
Do you mean that?
I don't think this is a real deal in design/experience😂
I don't understand "cracked" ... Sorry for my English

"window 'cracked' open" = "window a little open" - english is fun!
The only way to prevent this would be if a deflector raised up above the front of the glass as its opening to deflect air from trying to enter the cabin. The air is being forced into the cabin and without the windows open, the cabin has higher air pressure and cannot equalize that pressure fast enough - as such the wind "buffets" (helicopter) against the window.
If either side window is open, the air pressure can be equalized much easier.
It's like in some cars where if you only open 1 side window you get the same 'helicopter' noise.
