The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...

Example trajectory of CARL surfing a vortex ring for propulsion. In response to sensed acceleration, CARL autonomously executed a short burst maneuver to become entrained into the material boundary of ...

A European study into Vortex Ring State (VRS) – one of the helicopter industry’s most pernicious and persistent safety risks – has concluded there are only minor differences between the effectiveness ...
