Flight Dynamics, Simulation, and Control of Aircraft: For Rigid and Flexible Aircraft explains the basics of non-linear aircraft dynamics and the principles of control-configured aircraft design, as applied to rigid and flexible aircraft, drones, and unmanned aerial vehicles (UAVs). Addressing the details of dynamic modeling, simulation, and control in a selection of aircraft, the book explores key concepts associated with control-configured elastic aircraft. It also covers the conventional dynamics of rigid aircraft and examines the use of linear and non-linear model-based techniques and their applications to flight control. This second edition features a new chapter on the dynamics and control principles of drones and UAVs, aiding in the design of newer aircraft with a combination of propulsive and aerodynamic control surfaces. In addition, the book includes new sections, approximately 20 problems per chapter, examples, simulator exercises, and case studies to enhance and reinforce student understanding. The book is intended for senior undergraduate and graduate mechanical and aerospace engineering students taking Flight Dynamics and Flight Control courses.

This book describes the methods of signal processing used in the non-destructive diagnostics of mechanical and electrical properties of high-voltage electrical machines. Traditional and less traditional methods are given, which allow measuring the mechanical and electrical properties of these machines in order to determine their technical condition, including a description of their measurement methods. Separate chapters are devoted to the causes and methods of measuring and evaluating partial discharges arising in the insulation systems of high-voltage electrical machines. The following chapters provide an overview of the test methods used in the non-disassembly diagnostics of high-voltage transformers, rotary machines, high-voltage cables, insulators, surge arresters and circuit breakers.

The idiots got you down? Get a needle and thread and stab your stress away with this collection of wash-your-mouth-out-with-soap cross-stitch patterns. Cursing a blue streak has never been so satisfying! There are times when just hollering obscenities won’t do—you need to stab something. Now you can do both. Maybe Swearing Will Help combines two of the best stress-relievers—cursing, and cross stitch—into one of the most irreverently enjoyable crafting experiences you’ll ever have. With 25 patterns from the crafting world’s most bad-ass cross-stitch designers, this book has everything from a modern take on the traditional sampler to retro comic book designs, all with snarky to downright foul-mouthed phrases. It is definitely not your grandmother’s cross stitch!

This book applies traditional reliability engineering methods to prognostics and health management (PHM), looking at remaining useful life (RUL) and its dynamics, to enable engineers to effectively and accurately predict machinery and systems useful lifespan. One of the key tools used in defining and implementing predictive maintenance policies is the RUL indicator. However, it is essential to account for the uncertainty inherent to the RUL, as otherwise predictive maintenance strategies can be incorrect. This can cause high costs or, alternatively, inappropriate decisions. Methods used to estimate RUL are numerous and diverse and, broadly speaking, fall into three categories: model-based, data-driven, or hybrid, which uses both. The author starts by building on established theory and looks at traditional reliability engineering methods through their relation to PHM requirements and presents the concept of RUL loss rate. Following on from this, the author presents an innovative general method for defining a nonlinear transformation enabling the mean residual life to become a linear function of time.
