The second prospective design of the morphing wing includes the alteration of the camber of the wing. The camber is a critical feature of an airplane wing as it has a direct effect on the lift produced at the different cruising velocities.

Wing design impacts an aircraft’s lift. Aircraft wings can be understood by considering a cross-sectional slice of the wing. The leading edge is the front tip of the wing, while the back tip is called the trailing edge. A straight line distance between these points is referred to as the chord. The camber refers to the curvature of the wing’s upper and lower surfaces and can be visualized by the mean line, which is a line that is an equal distance from the top and bottom of the wing.

The location of the maximum camber of aerofoil will affect the lift coefficient and the induced drag coefficient. The pressure distribution will change if the location of the maximum camber varies along its chord.

There are basically three kinds of flow control strategies proposed (a) designing the high lifting airfoil surfaces by using camber or variable camber, (b) providing sharp trailing edges for airfoils so that the separation occurs smoothly, and (c) using flow control devices. High lifting airfoil surfaces minimise the adverse pressure gradients on the upper side of the airfoil by suitably selecting the camber. This could increase the lift of the airfoil by delaying the flow separation. Sharp trailing edges ensure to provide a steady flow by making the separation line fixed (Manigandan et al. 2018a). However, flow separation at the sharp trailing edges results in a decrease of leading edge thrust and could cause high drag at manoeuvre conditions. Flow control devices, on the other hand, have the potential to give flexibility to the aircraft designer on the aerodynamic constraints. It also allows designing the high lifting airfoil surfaces of relatively simple shapes as compared to that of the other two methods mentioned above. The flow control devices may also be an effective method of reducing the cost of flow control.

For the cambered airfoils (Figure 7), the increase of the Reynolds number improves the performance of the airfoil as well. In comparison with the symmetrical airfoils of the same thickness, these cambered airfoils perform better, showing higher values of the lift coefficient with similar values. (or just slightly lower) of the stall angle. The global tendency that may be appreciated is the increase of the stall angle and the lift coefficient with the increase in thickness. Adding camber to the airfoils (2%) increases the lift values and decreases the drag ones with respect to the symmetrical airfoil. Although the stall angle decreases slightly in comparison with the symmetric airfoils, the performance of the cambered airfoils is better. Finally, the increase of the Reynolds number causes an increase in CL and the stall angle and a decrease in CD.
