The Fluid Physics of Parachut Inflation

AUG 01, 1993
Cloth packed to the density of oak emerges from its container in a second, changes its shape from cylindrical log to ‘cloth streamers’ to hemispherical cup in another 2 seconds, and decelerates a one‐ton payload from the speed of sound to highway speed limits.
Carl W. Peterson

Parachutes have a fascinating history and a promising future. They were born long before airplanes, in ancient China. Leonardo da Vinci made sketches of a parachutelike device at the end of the 15th century, and Fauste Veranzio parachuted from a Venetian tower in 1617. By the time airplanes arrived on the scene, parachutes were older than Methuselah.
