Conducting a sea trial is a necessary step upon delivery of a ship. This activity not only documents and validates anticipated ship speed and power, but if done correctly also provides performance data that can be useful for design purposes. The same holds true for underwater vehicles in general and thrusters in particular. However, while gathering data may seem easy, extracting useful trial data for typical UVs can often be pretty challenging.We should start with an understanding of the system – the Vehicle-Propulsor-Drive system.

From the standpoint of vehicle propulsion physics, an unmanned underwater vehicle (UUV) is little different from your personal ski boat or a tanker. It shares the Vessel-Propulsor-Drive system model, which allows a Propulsor to convert Drive energy into thrust for the purpose of moving a Vessel. The basic principles of thrust equilibrium and motion are common to all three, as are the translation of rotational energy into axial thrust by the central element of the system – the…

HydroComp is releasing a major upgrade for its NavCad software tool, the company announced today. NavCad has been used for resistance and propulsion prediction for nearly three decades, and a "Premium Edition" is now available for users wanting a greater level of analytical capability. New features include a scripting (macro) API. This includes an easy-to-use scripting language that provides batch processing capability. Premium users will also be able to run NavCad from third-party software, including spreadsheets or simulation tools, as a calculation engine (i.e., coupled solver).
