The Nova Ray patented arcuate wing design solves long-time industry struggles with cable drag in strong currents. The wing design eliminates the phenomenon know as “Dutch Roll Instability”, a problem experienced by flat wing designs. The arcuate-shaped wings of the Nova Ray counteract the lifting force of the umbilical (also described as the tether or cable). Therefore, the speed of the boat (or other vessel) or current has little effect on the operational stability of the Nova Ray. The wings increase cable use efficiency and reduce the amount of cable necessary to operate or tow at depth.
Nova Ray’s arcuate wing configuration is remarkably stable in turbulent currents and provides true axis flight. There is little tendency for the vehicle to rock in shifting currents. The wings, combined with other secondary control surfaces, tend to counter any destabilizing forces. The close proximity of the thrusters to the control surfaces allows for very tight maneuvering. The overall result is an ROV system that can do more and perform where other underwater systems cannot.
