Abstract

Recent interest in flight through gusty winds has given rise to a large body of work on discrete large-amplitude gust encounters where the magnitude of the flow disturbance is large enough to incite massive flow separation. This paper outlines and introduces work performed as part of the North Atlantic Treaty Organization’s Science and Technology Organization’s Task Group AVT-282 on the unsteady aerodynamic response of rigid wings in gust encounters, with a focus on two-dimensional wings passing through large-amplitude transverse, vortex, or streamwise gusts. Definitions and parameterizations of a gust encounter and research questions addressed by the group are given here, along with plans for near term future work.

A. Jones’s work at the University of Maryland is supported by the U.S. Air Force Office of Scientific Research under grant FA9550-16-1-0508 and the National Science Foundation under grant no. 1553970. O. Cetiner’s work at Istanbul Technical University is supported by the Scientific and Technological Research Council of Turkey grant 115M358, titled “For the Application on UAVs and MAVs, Gust Effect on the Performance of Wings in Motion (Maneuver or Flapping) and Flow Control Attempts.” The authors would like to thank all of the members and participants of AVT-282 for their efforts on this long-term research effort. Thanks also to Michael Ol for assembling the tabular overview of the AVT-282 experiments, and for his efforts as cochair of the precursor to AVT-282, ET-154 on “Incompressible Aerodynamics of Large Gust Encounters for Rigid Bodies.”
