NUMERICAL INVESTIGATION OF TWO ELEMENT CAMBER MORPHING AIRFOIL IN LOW REYNOLDS NUMBER FLOWS [PDF]
Journal of Engineering Science and Technology, 2017 Aerodynamic performance of a two-element camber morphing airfoil was investigated at low Reynolds number using the transient SST model in ANSYS FLUENT 14.0 and eN method in XFLR5. The two-element camber morphing concept was employed to morph the baseline

Aerodynamic and Aeroacoustic Performance of Spanwise Morphed Airfoils [PDF]
AIAA AVIATION 2020 FORUM, 2020 Experimental studies of a NACA 0012 airfoil fitted with six different spanwise morphed flap profiles were successfully carried out to characterize their aerodynamic and aeroacoustic performance. The airfoil was tested with six configurations with different spanwise flap camber with a maximum deflection angle of β = 10◦ on one side and a minimum ...
