Rotorcraft Aeromechanics


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.




Casting Forward


Book Description

In Casting Forward, naturalist, educator, and writer Steve Ramirez takes the reader on a yearlong journey fly fishing all of the major rivers of the Texas Hill Country.

It is the story of a living, breathing place where the footprints of dinosaurs, conquistadors, and Comanches have mingled just beneath the clear spring-fed waters. This book is an impassioned plea for the survival of this landscape and its biodiversity, and for a new ethic in how we treat fish, nature, and each other.




Sweeping Forward


Book Description

The X-29 was an unusual aircraft with a truly unique silhouette. It combined many features that challenged the technologies of its day and represented special problems for the developers and the team of testers responsible for documenting its features and design goals. This book is a look at the "big picture" of what this team accomplished in a relatively fast-paced test program involving the truly unique X-29.
