Asymmetric
The asymmetric configuration is a highly efficient propulsion solution for applications in which the thruster is used in one primary direction. It is typically used as the main propulsion for battery driven vehicles, where efficient propulsion has a positive effect on the duration of the mission.
The consequence of optimized efficiency in the forward direction is reduced efficiency in the reverse. However, the thruster will still provide enough thrust to move even large vehicles in the reverse direction.
Symmetric
The symmetric configuration is superior in subsea operations which require that the thruster be equally efficient in both directions. In the symmetric configuration, the thruster is optimized to deliver the same amount of thrust in both directions. This setup is often used in station keeping ROVs where it is important to position the ROV even in strong currents.
Compact
This thruster is ideal for compact vessel integration. By using a symmetric propeller, the thruster functions optimally as a tunnel thruster built into the hull of a subsea vehicle. Often used for vehicles that perform station keeping and depend upon exact positioning in the water.
Performance Data for VXL
The figure below shows the performance of the thruster. The graphs are based on measured data. These measurements are preliminary and may be changed as more accurate measurement methods are developed.
Seawater Temp. vs. Max Power
The internal motor temperature must never exceed 70 degrees Celsius. Thruster power is thus dependent on the temperature of the surrounding seawater.
The influence of seawater temperature is shown in the table below.
