As spinning is still involved in around 60% of all aircraft accidents (BFU, 1985 and Belcastro, 2009), this aerodynamic phenomenon is still not fully understood. As U.S. and European Certification Specifications do not require recoveries from fully developed spins of Normal Category aeroplanes, certification test flights will not discover aeroplane mass and centre of gravity combinations which may result in unrecoverable spins. This book aims to contribute to a better understanding of the spin phenomenon through investigating the spin regime for normal, utility and aerobatic aircraft, and to explain what happens to the aircraft in terms of the aerodynamics, flight mechanics and the aircraft stability. The approach used is to vary the main geometric parameters such as the centre of gravity position and the aeroplane’s mass across the flight envelope, and to investigate the subsequent effect on the main spin characteristic parameters such as the angle of attack, pitch angle, sideslip angle, rotational rates, and recovery time. First of all, a literature review sums up the range of technical aspects that affect the problem of spinning. It reviews the experimental measurement techniques used, theoretical methods developed and flight test results obtained by previous researchers.

By  E-Books  0 Comments

Muon Spin Rotation, Relaxation, and Resonance: Applications to Condensed Matter By Alain Yaouanc, Pierre Dalmas de Réotier
2010 | 504 Pages | ISBN: 0199596476 | PDF | 8 MB
Primarily intended for postgraduate students and researchers in the fields of condensed matter science, chemical physics and material science, who plan to use the muon spin rotation, relaxation amd resonance (µSR) techniques, this book combines for the first time a detailed discussion of the physical information contained in the measured polarisation functions with real-life examples taken from the literature. It is divided in three main parts. The first part presents some typical results of the application of µSR and explains the basic principles involved. The second part is the core of this book. It presents a comprehensive discussion of the measured polarisation functions. In the third part we analyse in four chapters selected examples taken from the following fields: diffusion properties of muon and muonium, magnetism, superconductivity, and muonium centres in materials. The book is completed by an epilogue and eight appendices.

#1 New York Times bestselling author Jocko Willink’s fast-paced thriller Final Spin: A story of love, brotherhood, suffering, happiness, and sacrifice. A story about life.Johnny…Shouldn’t be in a dead-end job.Shouldn’t be in a dead-end bar.Shouldn’t be in a dead-end life.But he is.It’s a hamster wheel existence. Stocking warehouse store shelves by day, drinking too much whiskey and beer by night. In between, Johnny lives in his childhood home, making sure his alcoholic mother hasn’t drunk herself to death, and looking after his idiosyncratic older brother Arty, whose world revolves around his laundromat job. Rinse and repeat.Then Johnny’s monotonous life takes a tumble. The laundromat where Arty works, and the one thing that gives him happiness, is about to be sold. Johnny doesn’t want that to happen, so he takes measures into his own hands. Johnny, along with his friend, Goat, come up with a plan to get the money to buy the laundromat. But things don’t always go as planned…
