PropCad 2021: Press Release

New utilities for blade trimming and washback. HydroComp PropCad 2021 is the most powerful version of PropCad to date. PropCad has always been the go-to tool for designing marine propellers, 2D drawings, and 3D CAD models – but new features expand PropCad’s role into...

Hull-Propeller Interaction – Part 2: Propeller Performance

This two part series on Hull-Propeller Interaction concludes with a session on Propeller Performance (Part 2). We discuss “wake-adapted” propeller design and analysis, as well as differences between steady and unsteady performance and calculation....

Article: Fifty Years of Computers for Propeller Design

By Don MacPherson, HydroComp When asked to reflect on the use of computers for propeller design over the last fifty years, my first reaction was to think about my own history with computers. I painted houses one summer in the mid-1970’s to buy a TRS-80 that I took...

Hull-Propeller Interaction – Part 1: Wake Fields

This two part series on Hull-Propeller Interaction complements our previous webinar on propeller-radiated noise with a focus on Wake Fields (Part 1) and Propeller Performance (Part 2). We discuss in Part 1 how velocities into the propeller are affected by the hull...

Surface-Piercing Propellers: Geometric Modeling with PropCad

Surface-piercing propellers (SPPs) have a very specific blade form, with cleaver shaped outlines, high pitch-to-diameter ratios, and carefully crafted wedge-shaped sections. As a result, successful surface-piercing propellers require the use of unique design elements....

This article has been reprinted with permission from the October/November 2020 issue of Marine Propulsion & Auxiliary Machinery. Successful vessel performance outcomes don’t happen by accident. They start with the analysis of a complete Vessel-Propulsor-Drive...

Waterjets in NavCad

We all know that waterjets are a very effective propulsor for high speed craft. But how do we model waterjet performance for speed-power calculations? What is the influence of hull form on their ability to drive a craft? How are waterjets different from propellers for...
