"A gripping action story with a vein of star-crossed romance. In this prequel to 2022's THE RED CANOE, Buck, aka Michael Fineday, aka Red Deer is on his way to track down his wayward brother in the Twin Cities, when he's trapped in a snowstorm and rescued by Sally, a girl who is fighting her own demons. Though intrigued by Sally, most of Buck's time is spent trying to unravel his family's involvement with an elaborate racket which has recently gotten his cousin Ruben and his half-brother Bear killed.Eli, Buck's surviving brother, is up to his neck in the racket that involves insurance fraud and stolen vehicles, and unwilling to tell Buck the truth. The racketeer's kingpin thinks Eli has something they want-which is both his death warrant and his salvation. The problem is, Eli doesn't know exactly what the something is or how to find it; his only clue is a phrase in Anishinaabe language Ruben scrawled on the wall of his room before he was killed, and it's up to Buck to track it down.Meanwhile, Sally and Buck grow closer through the shared wounds of their difficult pasts; and Buck teaches her some Ashinaabe language and cultural practices. Strangely, all roads-both Sally's and Buck's-lead to the Witch Tree, an important spiritual reservoir in Native American religion, and where he is forced to face the many facets of his own identity and find a way for them both to heal."--

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.
