Abstract
The air scoop opening at the leading edge of a flexible, ram-air inflated airfoil canopy, is framed between curved lip sections extending tangentially from the upper and lower surface members of the canopy to prevent airflow separation adjacent the leading edge and the drag producing effect thereof. A baffling curtain extends across the air scoop opening.
