Effect of forward velocity on rectangular wings flapping with piezoelectric actuators

In the current study, unsteady aerodynamic forces of two flapping rectangular wings are investigated using two different materials namely, aluminum and plexigla ss. Two different materials used for the wings are intended to observe the effects of the wing flexibility on instantaneous aerodynamic forces. A Lead Zirconate Titanate (PZT) piezoelectric actuator is used for flapping the wing models. The wind tunnel tests are performed with velocities ranging from 0m/s to 12 m/s. Output flapping frequencies are measured and compared for the wings investigated
