dc.description.abstract	Animals and insects have been investigated because of their locomotion form that allows simultaneous thrust and lift production at low Reynolds numbers. The present study focuses on the experimental investigation of a plunging NACA0012 airfoil under asymmetric conditions. Tests are conducted with a Reynolds number of 1x10^4, considering two nondimensional velocities, kh=0.25 and 0.50. Each of these conditions is tested with different levels of asymmetry, depending on the limitations of the experimental apparatus. Flow visualization indicates that asymmetric movements produce both thrust and lift simultaneously and that increasing the asymmetry parameter and the reduced frequency have a similar impact: leading edge vortices to become stronger and are formed earlier. The present study is an earlier work that explores the existent void of experimental data regarding asymmetric conditions of unsteady airfoils.	pt_PT
