What is the effect of a wider blade on a thruster compared to a narrower blade of the same power rating and diameter?

A wider blade on a thruster compared to a narrower blade of the same power rating and diameter typically generates more thrust under certain conditions. The design characteristics of the blade influence the hydrodynamics and performance of the thruster.

When considering the correct implications of a wider blade, if it is not well-designed for the specific application, it can lead to increased drag and turbulence, which may not effectively convert the provided power into thrust. This means, instead of having an advantage, the wider blade may actually become less effective in creating the thrust needed for the desired maneuvers. If a blade is overly wide, it could disrupt the flow of water around it, thus diminishing the overall thrust capability when compared to a narrower blade, which can enable a more efficient flow.

Furthermore, the potential for cavitation and noise can increase with a design that doesn't match the operating conditions, as the wider surface area may not handle the water flow as efficiently as a narrower blade. Thus, the implications regarding cavitation and power consumption are closely tied to the design features and operational context of the thruster.

In summary, the thrust capability could be reduced because the wider blade might not effectively harness its mechanical power due to the way it interacts with the water flow, making it
