Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

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 ...

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 ...
