Excerpt from Screw Propellers: And Estimation of Power for Propulsion of Ships; Also Air-Ship Propellers
John bourne, in his Treatise on the Screw Propeller, published in 1867, states that the screw propeller is, in all probability, a very ancient contrivance. In China it is said to have been known for ages; but in European countries the idea of a screw propeller appears to have been derived either from the windmill or smoke-jack, or from the screw of Archimedes, an instrument much used in some countries for raising water.
Seaton, in his work on screw propellers, traces its develop ment from the time when man first used his hands as paddles, through the pulling oar and the scullin g oar, and the modified application of the latter in the form of the screw propeller.

Paperback. Zustand: New. Print on Demand. This book delves into the fascinating world of screw propeller propulsion, a technology that revolutionized marine travel. The author, an expert in the field, traces the evolution of the screw propeller from its ancient origins to its widespread adoption in the late 19th and early 20th centuries. He unpacks the complexities of screw propeller design, emphasizing the interplay of key factors like hull form, power, and propeller geometry, all of which contribute to propulsive efficiency. The book explores the critical concepts of thrust deduction and wake gain, two forces that either hinder or enhance the efficiency of the propeller's operation. The author, drawing upon his extensive experience and meticulous research, provides practical methods for designing and optimizing screw propellers, aiming to maximize their performance and efficiency. This book offers a valuable resource for anyone seeking a deeper understanding of this vital technology and its role in naval engineering.
