Development and Testing of a Steerable Cruciform Parachute System
… a parachute payload system which is capable of precision aerial delivery yet only represents a modest cost increase over ballistic unguided systems. In order to develop such a system, first a canopy is selected. The canopy should be simple and inexpensive to make; in this case a cruciform canopy …
