B4:

As small AOA, how do you see C₂ varies with a ?

As AOA increases, does the relationship you observes in B1 continues? Why?

Is there any difference in the C₁ vs a relation you observed in B1, for airfoil

with difference thickness, and different camber?

At even higher AOA, what happen to the relationship between C₂ and a? In

your own words, describes the flow phenomenon that has occurs.

B5: Tabulate and discuss the Stall AOA and maximum C₂ of the 4 airfoil studied.

B6: Compute and discuss the lift-curve slopes for the 4 airfoil studied.
