PropExpert

What is PropExpert?

Helix sizing and analysis

Providing all tools for proper propulsion selection

PropExpert offers the most up-to-date techniques presented in an easy-to-use and powerful package. Calculate the ideal diameter, pitch, reduction gear ratio, and blade area for open or duct ed helix systems.

The Go-To Sizing tool for propeller manufacturers and distributors

PropExpert is ideal for selecting and analyzing propeller systems for work boats and pleasure craft. Safely identify some components of the vessel's specific propulsion system with just a few inputs. The installed commercial propeller library can be extended with your own data and create your own library of vessels, engines and gearboxes. Use data from a previous assessment or similar vessel to anchor your model to real-world performance, or use the PropExpert speed estimation formula when the data is not available.

PropExpert's project library can help you manage your database of projects, vessels, propellers, engines, and gear models. Achieve maximum performance with the two-stage software size solution to analyze speed, buoyancy, power, and efficiency.

Improve accuracy with sea test data

PropExpert's advanced features allow you to deepen your analysis. Use data from a previous assessment or data from a similar vessel to anchor your model to real-world performance - or use propexpert's speed estimation formula when the data is not available.

Size virtually any propeller

PropExpert determines the ideal diameter, pitch, blade area and RPM for commercial internal propellers from two to five blades, from about 450 mm (18 inches) in diameter to about 2.5 m (100 inches). Both gawn and aluminum foil (B series) propellers are supported, as are duct propellers (Kaplan). PropExpert evaluates shell and "progressive pitch" propellers (curved) and offers special consideration for folding propellers and propellers in stern pockets.
