Book Description
"Blade Element Rotor Theory presents an extension of the blade element rotor theory to describe the dynamic properties of helicopter rotors. It focuses on the more precise mathematical determination of the forces and moments by which a rotor affects its rotorcraft at specified flight conditions and control positions. The book is intended for graduate students and researchers studying rotor dynamics and helicopter flight dynamics. Analyzing the impact of non-uniform blade parameters, the book covers blade twisting, non-rectangular planform shape of a blade, and inhomogeneous airfoil along a blade"--

Book Description
A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics covers much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics include many of the key performance attributes and the often-encountered problems in rotorcraft designs. This comprehensive book presents, in depth, what engineers need to know about modelling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behaviour. The first third of the book is an introduction to rotorcraft aerodynamics, blade motion, and performance. The remainder of the book covers advanced topics in rotary wing aerodynamics and dynamics.

Book Description
Blade Element Rotor Theory This book presents an extension of the conventional blade element rotor theory to describe the dynamic properties of helicopter rotors. The presented theory focuses on the accurate mathematical determination of the forces and moments by which a rotor affects its rotorcraft at specified flight conditions and control positions. Analyzing the impact of a blade's non-uniform properties, the book covers blade twisting, the non-rectangular planform shape of a blade, and inhomogeneous airfoil along the blade. It discusses inhomogeneous induced airflow around a rotor disc in terms of the blade element rotor theory. This book also considers the impact of flapping hinge offset on the rotor's dynamic properties. Features • Focuses on a comprehensive description and accurate determination of the rotor's aerodynamic properties • Presents precise helicopter rotor properties with inhomogeneous aerodynamic properties of rotor blades • Considers inhomogeneous distribution of induced flow • Discusses a mathematical model of a main helicopter rotor for a helicopter flight simulator This book is intended for graduate students and researchers studying rotor dynamics and helicopter flight dynamics

Book Description
An extension of previous work on the theory of self-excited mechanical oscillations of hinged rotor blades has been made. Previously published papers cover the cases of three or more rotor blades on elastic supports (such as landing gear) having either equal or unequal support stiffness in different directions and the case of one or two blade rotors on supports having equal stiffness in all horizontal directions. The missing case of one or two blades on unequal supports has been treated.
