RE: Symmetrical Airfoil LE Shape
Theory is one thing
The last TOC event had varous style models (as did other TOC events) - -sharp blunt le you name it - actual differences in performances?
not much if any - which indicated LE shape was critical
Our last TOC design- a Bucker with 11% airfoil - very gentle yet would snap easily recover quickly Just a nice 30% high point shape with gentle LE radius- about 3/16"" radius
wing loading- far far more important
