in reguard to my earlier post concerning incidence in the post," new guy with a question", i have a question or two to confirm my thinking about your excellent responce.
i think i have a fairly good understanding of "incidence" and of "angle of attack " and how they relate to each other,but i'm not sure how AOA is defined given different airfoil sections.
i understand that with a fully symetrical wing, AOA is a line prjectedthrough the centers of both, leading edge and trailing edge, making the wing neutral, thus needing pos. incidence to creat lift bymounting the horizontal stabilizer with some negative incidence. the wing on my plane is semi symetrical- flat bottomed. so, given the definition of "AOA", i should mountmy wingwhere the bottom flat plane of the airfoilis parrallel to the fuse's reference line, which is intended to be horizontaly level in level flight. my incidence would thenbe the angle projected by a line throught the thecenters of the leading edge and the trailing edge of my wing, resulting in a positive incidence ofabout1-1/2degrees.......is this correct?or do i have to physicly mount the wing so that the bottom flat plane of the airfoil is angled a degree or soup in relation to the reference line?. by the print, the hor.stab is also mounted 0, so i should bring it's leading edge down a degree or so, correct?
thanks in advance, you've been very helpful!
