EM661 - Propulsion and Propulsors

Credits: 3

This course investigates ships and craft resistance, propulsion and the propulsors utilized to propel the vessel. Resistance will be studied considering all its facets including friction, wavemaking and form, considering both displacement vessels and those with dynamic lift including planing craft, hydrofoils, and air cushion vehicle. Propulsion considerations will investigate the hull/propulsor interaction and both resistance and propulsion will include how model testing is utilized for prediction and ship trials for verification. The consideration of propulsors will begin with propellers and their selection and design, including in an environment of cavitation. Other propulsive devices will be addressed as well as ducts, thrusters, cycloidal propellers and waterjets. Throughout the course, specific ship applications will be considered.

Prerequisites: EM660 - Hydrostatics and Basic Hydrodynamics, or equivalent.
