DESCRIPTION:A wing experiencing rapid and extreme manoeuvres can result in
  an unsteady separation process that leads to the formation of large-scale
  vortical structures that dominate the flow field\, a phenomenon known as 
 dynamic stall. This phenomenon is most commonly recognised as a hazardous 
 issue for rotorcraft vehicles\, but it can also occur on wind turbines\, f
 lapping or fluttering wing systems\, and aircraft undergoing aggressive ma
 noeuvres. Many of these systems operate in the high Reynolds numbers regim
 e for which aerofoils have been extensively studied\, however\, the litera
 ture appears to be missing experimental data for finite wings experiencing
  dynamic stall. The work presented includes an experimental comparison of 
 the performance data and three-component velocity measurements for wings o
 f AR = 3\, 4\, 5\, and an airfoil during an unsteady pitch manoeuvre at tr
 ansitional Reynolds numbers. \n
