Looking at Dole and Lewis textbook Figure 4 4 and Figure 4 3 you will evaluate Lift Curve slope Parameters of a Symmetrical NACA 0012 and Cambered Airfoil NACA 4412 of similar thickness and

Looking at Dole and Lewis textbook Figure 4.4 and Figure 4,3, you will evaluate Lift Curve slope Parameters of a Symmetrical (NACA 0012) and Cambered Airfoil (NACA 4412) of similar thickness and evaluate the thickness effect on Coefficient of Lift and AOA for cambered airfoils of different thicknesses (NACA 4412 and NACA 4406)

1. Find the CLmax for the two airfoils in Figure 4.4.What is the relationship between Camber and CLmax ?

2. Find the AOA at Zero Lift for the two airfoils in Figure 4.4.What is relationship between Camber and zero lift (CL = 0)?.

3. Find the AOA at CLmax for the two airfoils in Figure 4.4.What is the relationship between Camber and Stall AOA?.

4. Looking at Figure 4.3, what is the relationship between airfoil thickness, CLmax and AOA?
