Efficiency of lift production in flapping and gliding flight of swifts.

PLoS ONE, 2014
Many flying animals use both flapping and gliding flight as part of their routine behaviour. These two kinematic patterns impose conflicting requirements on wing design for aerodynamic efficiency and, in the absence of extreme morphing, wings cannot be ...

Experimental and numerical investigation of leading edge Krueger flaps at low Reynolds numbers [PDF]

, 2012
Recent publications examining the flight of Eagles have shown that leading edge feather deflections occur on the lower surface of the wings in free flight to create a leading edge flap analogous to a Krueger flap system.

Advanced Aerodynamic Technologies for Future Green Regional Aircraft

INCAS Bulletin, 2014
Future Green Regional Aircraft (GRA) will operate over airports located in the neighborhood of densely populated areas, with high frequency of takeoff/ landing events and, hence, strongly contribute to community noise and gaseous emissions.
