“…However, testing an actual parafoil was outside the scope of this research. The present model is based on the FASTWing CL parafoil [7]. It is based on the geometry, dimensions, weights, and some aerodynamic properties of the FASTWing CL system, but complete aerodynamic data was not available.…”

“…This study considers a large-scale parafoil for 6000 kg payload modelled using available data on the FASTWing and FASTWing CL parafoils [7]. The research focuses on design of guidance laws for precision landing of the parafoil; then, a behavioural strategy for relative motion control of multiple parafoils is proposed and its effects on the baseline guidance are investigated.…”

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.
