Sometime ago I posted a topic about pressure fields in airfoils and how the disruption of boundary layers can lead to difference in a given airfoil potential. I remember before someting about laminar bubbles, that actually separate the transition states of airfoils on a wing surface. This separation happens mainly because of the pressure fields I discussed on the previous topic, which will change with respect to the different velocity distributions. The instability we were talking, I assume would be caused by this transition bubble since it creates large amounts of drag for the aircraft. To solve this it is used a device called turbulators, which can smoothe out the stress and even up the airfoil so that it isn't unstable anymore.

I would wonder how much stress it will give the airfoil on the wing without such a presence of the turbulator. I guess the design concept would have to be altered in this case. Anyway, any insight on this matter would be appreciated.

PS: Thanks for the previous responses, we can only benefit from hearing different answers.

Cheers.

Okay...

You stick the doohicky into the whatchamacallit, then take the thingamabob and jam it into the thingamajigy...

What if you de-nobberate the framus first? Will that cause excessive modulation of the positive ion flow, resulting in a reverseal of the flux capacitor, and diluting the xaxon crystaline matrix to the point where the whole thing just goes 'BING'?
