Propeller Design
English
By (author): Ohad Gur
Propellers have gained popularity in recent decades as part of UAVs, multi-blade drones, and VTOL air taxis. However, modern books dealing with propellers are scarce. Most of the rotating wing literature concentrates on helicopters. Other books dedicate specialized chapters to propellers, in most cases as part of general aerodynamic or performance texts. Propeller Design by Ohad Gur therefore fills a gap in modern literature amidst increased interest in the topic. This book sums up three decades of the author's experience with propeller analysis and design. As such, special care is given to the suitability of the analysis as part of a synergetic design framework.
The book starts with the general history of propeller evolution (chapter 1) and a view of the propeller design problem, which contains the fundamental vocabulary of propeller theory (chapter 2). Chapter 3 discusses propeller geometry and the parametric representation of its geometric properties. The aerodynamics of the propeller are reviewed thoroughly in chapters 4 through 7. Chapter 4 describes the basic blade-element model, BEM, used extensively throughout this book in various combinations. Chapter 5 describes three momentum theory models axial, general, and simpli?ed. Chapter 6 combines the BEM and momentum theory into blade-element/momentum theory, which is probably the most useful aerodynamic theory for propeller analysis. Finally, in Chapter 7, additional induced velocity theories are depicted, including vortex theory and lifting line model with three separate wake models. Chapter 8 describes the three standard engines used to power propellers: reciprocating, turboprop, and electric. Chapter 9 explains the propeller effect on the air vehicle on which it is installed. Chapters 10 and 11 deal with the acoustic and structure analysis of propellers. Chapter 12 closes the theoretical part of the book with a discussion of the propeller design process. It presents two signi?cant methods: Betz's based method and multidisciplinary design optimization, MDO. These are later demonstrated in four different design cases in chapter 13.
Although the book is aimed at engineers who strive to design propellers, it also bene?ts those who want to deepen their knowledge of propeller theory and design considerations. See more
