Throughout its development, slender body theory has been generalized to predict a large variety of aerodynamic coefficients for a wide class of flight bodies. For most applications, slender body theory provides only a qualitative predictive capability. There is, however, a set of slender body relationships which has been previously derived by Sacks that allows the individual pitchdamping coefficients and the pitch-damping coefficient sums to be related to each other. Until recently, it has been difficult to assess the accuracy of these relationships due to the lack of high-quality pitch-damping data or the lack of a higher order theory. The current work applies a recently developed computational fluid dynamics capability for predicting all three pitch-damping coefficients. From this analysis, the accuracy of these relationships has been assessed and their engineering significance demonstrated. One important result is that the pitch-damping relations developed by Sacks allow the individual pitch-damping coefficients to be determined from the pitch-damping coefficient sum with a high degree of accuracy.

Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.

Written by an internationally recognized teacher and researcher, this book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft such as tilt rotors and autogiros. The text begins with a unique technical history of helicopter flight, and then covers basic methods of rotor aerodynamic analysis, and related issues associated with the performance of the helicopter and its aerodynamic design. It goes on to cover more advanced topics in helicopter aerodynamics, including airfoil flows, unsteady aerodynamics, dynamic stall, and rotor wakes, and rotor-airframe aerodynamic interactions, with final chapters on autogiros and advanced methods of helicopter aerodynamic analysis. Extensively illustrated throughout, each chapter includes a set of homework problems. Advanced undergraduate and graduate students, practising engineers, and researchers will welcome this thoroughly revised and updated text on rotating-wing aerodynamics.
