... is constant over the range of zero to twenty percent of the vent ratios and for higher vent ratios when the upper bluff body is smaller than the lower one the drag force decreased, and it increased when the upper bluff body is larger than the lower one.

... 10 07 2009 In a parachute, an increase of drag force occurs when the frontal area or the area of its canopy is increased. To prevent the technical problem in deployment of large parachutes, designing parachutes consisting of more than one canopy with smaller frontal area with an air...
