Stall is defined as the condition where the intended laminar flow around the aerofoil ceases being laminar to a great extent. It has almost nothing to do with wings or aircraft except the above mentioned aerodynamic condition just so happens to lower the wing efficiency (lift/drag ratio for that aoa) below what is acceptable for an aircraft for flying. Stall also affects other things, like turbine blades, fast-moving cutting tools in air or lubricant, fans, structures exposed to high speed air or gas or liquid flows, etc etc. As you have said, if the engines are powerfull enough you 'can't' stall. Also usually aerodynamic stall has a latching behavior, in that the transition between stalled and unstalled mode is abrupt in both directions. Peter -- http://www.piclist.com#nomail Going offline?
