Unsteady Aerodynamics for Micro Air Vehicles (Aerodynamique instable pour micro-vehicules aeriens)

Abstract

Recognizing that the flowfield environments encountered by Micro Air Vehicles (MAVs) are fundamentally unsteady - whether for fixed-wing, rotary-wing or flapping-wing configurations, AVT-149 seeks to address fundamental questions in unsteady low Reynolds number aerodynamics to establish a better knowledge base for aerodynamic MAV design. AVT-149 studied computationally, experimentally and analytically a progression of abstracted configurations, from 2D airfoils in pure-plunge through 3D wing planforms in plunge and pitchplunge, to better understand the interplay between the motion, the flowfield, and the resulting aerodynamic loads history. We also compare translational and rotational transient motions.
