Optimize and Understand Your Propeller

HydroComp’s PropElements brings a specialist tool to a broader engineering community. PropElements is designed not only for propeller specialists and manufacturers, but for naval architects and vehicle designers as well.

Wake-Adapted Propeller Performance

PropElements provides an optimizing design stage between parametric specification and full 3D design for manufacture. It builds on the system specification of necessary propeller characteristics (such as those from NavCad) to the design or evaluate a propeller in greater detail to meet the ship mission objectives.

Many large, merchant ships utilize custom propellers and more smaller ships, yachts, and workboats also appreciate the benefits of a custom propeller. Naval architects now have a new set of technical challenges to ensure acceptable performance and compliance with design requirements. To fully take advantage of the benefits that custom or semi-custom propellers make available – or to evaluate them in service – naval architects must look to a different kind of propeller calculation. Extensive validation studies for PropElements confirm it is unmatched in calculation fidelity and workflow efficiency.

Add Propeller Calcs to Your Workflow

PropElements’ numerous import/export options makes it an important companion for our NavCad and PropCad software, as well as the perfect pre-processor for higher-order flow codes, CFD, and FEA. Connect the KT-KQ data to NavCad for “Aligned Series” prediction of propeller performance. Then, when the propeller design for performance has been completed with PropElements, its design for manufacture can be conducted in PropCad.

CFD-Friendly Analysis

A closely-coupled connection between a CFD code and HydroComp PropElements software offers a high-fidelity and highly-efficient alternative to an actuator disk. Using easy-to-implement capabilities for object-oriented scripting and cross-product connectivity, it is the ideal propeller performance server for integrated hull-propeller analysis with CFD.
