JohnSherman 1 #27 March 27, 2013 Quotefirstly are all turbulence induced collapses a function of detached laminar flow over the wing? Can collapses be caused by external mechanical turbulence exerting a direct force on the surface (flying through rotors behind trees for example) Both scenerios do the same damage. They blow the boundry layer off. Unfortunitely is is not "Laminar Flow". It is "Turbulant flow". Quoteand if so, secondly what are the relative advantages to the prevention method you describe, vs maintaining a high internal pressure via full speed flight to increase the force necessary to induce a collapse. So soon you forget. The internal pressure is not greater at higher speeds. In fact the differential pressure is less at high speeds. Making it easier to detach the boundry layer. "The point of greatest lift is just prior to an impending stall". The point of greatest lift is also the point of the greatest pressure differential. This point is the most resistive to rotors et. al. A wing is a wing. The physics are the same. Pilot perceptions are extremely unreliable. Quote Share this post Link to post Share on other sites
