【Abstract】 This paper introduces mainly the development of parafoil form for improvement of the drag performance abroad recently. The significant improvements have been applied to not only sport canopies but also normal parafoil. The development of the large scale parafoil is also described. At present the payload weight has been increased up to 16.30 t, the canopy area up to 1000 m2, which indicates that the development of parafoil is very rapid and is of significance to civil and military applications.更多还原
