Why Wings for True Axis Flight®?

The winged Nova Ray® ROV design solves long-time industry struggles with cable drag in strong currents. The patented wing design eliminates the phenomenon known as "Dutch Roll Instability" by incorporating the "Arcuate" form wing with a rudder.

The bow-shaped wing of the Nova Ray® ROV counteracts the lifting force of the umbilical or tether. Therefore, the speed of the boat or current will have little effect on the operational stability of the Nova Ray® ROV. The wing increases cable use efficiency and reduce the amount of cable necessary to operate or tow at depth. At the same time, it creates a remarkable stability ROV.

Under thruster power, the wing operates just as a high winged airplane would in free flight. Under tow, the arcuate wing, combined with the seamless shift in the center of rotation from the cable pull, produces a stable configuration. Read more at Technology.

What kind of Umbilical is used?

The Nova Ray uses an umbilical for precision sending and receiving of communications between the ROV and the pilot Control Console, and for sending power to the vehicle.

  • Standard: 12 conductor umbilical, neutrally buoyant.
  • Standard Length: 300 ft. umbilical (longer lengths available)

Fiber Optics: Option available at additional cost and delivery time.

Where is the Umbilical attached and why this location?

There are two umbilical attachment points. The primary one is located at the top of the hull just forward of center of mass. A second attachment point is placed well forward of center of mass, and serves as a secondary connection in the event of unusual stress. When using the second attachment only, the ROV can continue to operate at reduced depth or return to the surface for a replacement link (recommended approach).

What are the advantages of Dual Mode operation?

Underwater conditions are continually challenging. Thrusters can be used to visually inspect a target located while towing, without having to launch additional equipment. Having both options allows for the ability to work in adverse conditions and environments more efficiently, saving time and money.

What size Thrusters are used and what is the rated horsepower?

The Nova Ray® is designed with thrusters to operate in strong currents with minimum and maximum power ranges.

  • Standard: two, ¼ hp thrusters, variable DC power.

Option: Increased horsepower for enhanced project needs.

How many Knots can be achieved under Thruster power and under Tow?

  • 4 ½ knots under thruster power, and with 1/3 hp up to 6 knots.

Up to 9 knots under tow with deeper operation and less cable than other Underwater Towed Vehicles (UTV).

What kind of Navigational Software is used?

Coral Partners, LLC. developed its own proprietary Command and Control software. This was a necessary and important step for Nova Ray® performance specifications. Its unique design and the challenging demands for performance in adverse conditions required an equally robust Command and Control software system. Navigational systems are available from several companies, and can be integrated into the Nova Ray® system, and work in conjunction with the vehicle's Command and Control software.

How does the Command and Control system work?

The ROV pilot has up to four auto pilot modes:

  1. Wings Level
  2. Heading Hold
  3. Depth Hold
  4. Altitude Hold (optional altimeter purchase)

The Nova Rayâ has sophisticated software, engineered to compensate for deviations to course, depth and wing attitude. This enables the operator to multi-task and concentrate on specific project demands. To make control changes, the operator simply moves the joy stick or slides the thrust control.
