“…Among the challenges for the designers of ram-air parachutes is increasing the payload capacity of the parafoils while improving their glide ratio. For example, NASA's X-38 program, cancelled in 2003, involved development and testing of a 7500 ft 2 parafoil for landing a 25 000 lb spacecraft [1]. In Europe, the FASTWing CL (foldable adaptive steerable textile wing for delivery of capital loads) project [2], ongoing since December 2006, aims to develop a self-navigated system for cargo up to 6000 kg.…”

Much effort has been invested during the past decades in design of parafoils for a wide range of payloads and in development of means for their guidance. Existing parafoils are capable of autonomous navigation using the global positioning system and other onboard sensors. The purpose of this study is to explore the advantages of coordination among multiple autonomous parafoils. Each parafoil is able to navigate to the target on its own by following a real-time-generated reference trajectory. A new method for trajectory generation is presented and behaviour-based rules are developed that control the relative motion of the descending parafoils. The set of simple rules results in an emergent behaviour known as flocking. The coupling between trajectory following and flocking is studied in a multiagent simulation. The simulation uses a realistic six-degrees-of-freedom model of a heavy cargo parafoil. The obtained results demonstrate the possibility of flocking behaviour for guided parafoils. The flocking rules ensure safe separation between the vehicles headed for the same target and allow the parafoils to follow a reference trajectory as a group.
