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.... Read more
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... Read more
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.... Read more

The evaluation of Propeller Radiated Noise (PRN) has always been part of the assessment of internal noise, vibration, and habitability. In recent years, PRN has become a focal point for international regulatory efforts to reduce Underwater Radiated Noise (URN). While... Read more
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... Read more
