Nomenclature
D ab= ground distance from load release to system first vertical D bc = ground distance from first vertical to main parachute deployment D cd = ground distance from main parachute deployment to ground impact D bd = ground distance from first vertical to ground impact h c = altitude of system at main parachute deployment V c = system descent velocity at main parachute deployment V d = system descent velocity at ground impact V windbc = range of wind speed from first vertical to main parachute deployment V windcd = range of wind speed from main parachute deployment to ground impact r = mean miss radial distance for the operational field tests x , y = mean point of impact in Cartesian coordinates for the operational field tests r = standard deviation of the radial miss distance for the operational field tests x , y = standard deviation of the Cartesian coordinate of the payloads for operational field tests
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
