I don't take myself as being any kind of expert on the subject of aerodynamics but I've been around for a bit asking dumb questions when I've had the opportunity to pick brains of knowledgeable people and maybe this will stir the cauldron and get a response from some of the wizards that subscribe to this line. It has been my understanding that cutting the trailing edge blunt allows a plenum chamber effect that allows the upper surface low pressure fast moving slip stream to mix better with the high pressure slow slipstream from the bottom surface and produces a less tubulent wake field if only maginally and less induced drag. Go ahead guys inform me of the error of my ways. Don C John Bouyea <john...@speakeasy.net> wrote: I have a question about the thickness of the tailing edge section.

The Cirrus people told me this is done to improve the feel at higher rates of speed. (Interestingly, both Cirrus and Richard have aluminum ailerons.) Most of the KRs I have seen have very thin (i.e. sharp) trailing edge sections. Does anyone know definitively about what this type of change might do to the standard RAF airfoil?
