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 includes much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics cover 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 modeling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behavior. 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.

Update to the aeromechanics classic, Helicopter Theory. Dr. Johnson is a pre-eminent expert in rotorcraft aeromechanics and the book provides excellent treatment of all of the information necessary to design and analyze rotors and propellers for both traditional rotorcraft and modern eVTOL and UAS systems. Comprehensive collection of references in each chapter enable the reader to go easily go to even greater depth on advanced topics by finding the relevant research articles.
