MAE 136, Fall 2019

The following exercise is assigned to students in the ​Friday discussion​ as well as all students who have ​not taken Quiz 3​. ​ ​ ​ The following image represents the camber line of a flat plate airfoil:

The total length of the airfoil is 1 (note this is not the chordline and therefore not your integral bounds). It is angled halfway at 45​°.

1) Using thin airfoil theory, calculate ( alpha of zero lift)αL=0

2) Calculate Cl at .°α = 7
