PROPELLERS AND PROPULSION. IN: MODERN MARINE ENGINEER'S MANUAL

There are many definitions associated with ship propellers, and these tend to change somewhat over the years as new terms are added and old ones are dropped. More recently, an effort has been made to standardize terminology internationally. In 1975, the International Towing Tank Conference adopted a set of terms for propulsion and propellers, and some of these definitions are reproduced in the glossary. There are also a number of propulsor types included in the definitions. In general, these propulsor types operate along the same principle as the screw propeller and are discussed in this chapter, which provides an overview of ship resistance, propulsion, and propeller design.
