Paperback. Condizione: New. Print on Demand. This book presents a scientific method for understanding the behavior of wind around screws or propellers. The study of airscrews is important for the design of efficient aircraft, and this book shows how an understanding of air pressure, aerofoil motion, and thrust grading can be used to determine the best propeller for any given aircraft. The author presents complex mathematical analysis and provides usable formulas for determining propeller characteristics. The book also explores the efficiency of propeller blades with different cross-sectional shapes and includes a chapter on the stresses an airscrew experiences during flight. Overall, this book is a valuable resource for any engineer seeking to improve the design of their aircraft's propellers. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. …

"The problem of determining the form of air flow generated by an aerofoil, moving through still air is one that has so far defied, mathematical analysis. This problem, which applies equally to water and other fluids is one for which a solution has only been obtained when the aerofoil is a flat plate of infinite span." VERY GOOD HARDCOVER, ex-library withdrawn. Size: 8vo - over 7¾" - 9¾" tall. Ex-Library Withdrawn.…
