Keywords: Plunging- Pitching- unsteady- wind tunnel- reduced frequency

Unsteady aerodynamic experiments were conducted on a plunging airfoil in subsonic wind tunnel. The model was oscillated at two velocities, 30 and 60 m/sec, and a range of reduced frequencies, k=0.01-0.1. Effects of mean angle of attack as well as amplitude of the motion were investigated.
