Vortex Generator Technicalities, By Peter Garrison
AOA = Angle Of Attack
The angle with which the wing contacts the impinging air stream L/D = Lift to Drag ratio As AOA goes up, so does lift, but drag goes up too. Knowing what the L/D curve looks like for a specific airfoil as AOA increases is an important point in designing an aircraft to meet a stated mission. Clmax = Maximum coefficient of lift The AOA where the wings lift is maximum. Usually occurs at an AOA just before stall. L E Slats = Leading Edge Slats http://www.liming.org/ch801/slathistory.html "TJ400" wrote in message oups.com... AOA, L/D, Clmax and LE slats are what exactly?.... Been out of the whole sport aviation for some time and just trying to grasp it all over again.. thanks..
