This Element presents a unified computational fluid dynamics framework from rarefied to continuum regimes. The framework is based on the direct modelling of flow physics in a discretized space. The mesh size and time step are used as modelling scales in the construction of discretized governing equations. With the variation-of-cell Knudsen number, continuous modelling equations in different regimes have been obtained, and the Boltzmann and Navier-Stokes equations become two limiting equations in the kinetic and hydrodynamic scales. The unified algorithms include the discrete velocity method (DVM)-based unified gas-kinetic scheme (UGKS), the particlebased unified gas-kinetic particle method (UGKP), and the wave and particle-based unified gas-kinetic wave-particle method (UGKWP). The UGKWP is a multi-scale method with the particle for non-equilibrium transport and wave for equilibrium evolution. The particle dynamics in the rarefied regime and the hydrodynamic flow solver in the continuum regime have been unified according to the cell's Knudsen number.

Flight research takes up where the other instruments of aeronautical research -- wind tunnels, fluid dynamics, and mathematical analyses -- leave off. No matter how the equations suggest it ought to fly, only by studying actual flight, often demanding complicated and dangerous maneuvers, can researchers discover the limits of flight and the true characteristics of experimental flight vehicles. The National Advisory Committee for Aeronautics (1915) and its successor, The National Aeronautic and Space Act (1958) were created to find out.

Expanding the Envelope is the first book to explore the full panorama of flight research history, from the earliest attempts by such nineteenth-century practitioners as England's Sir George Cayley, who tested his kites and gliders by subjecting them to experimental flight, to the cutting-edge aeronautical research conducted by the NACA and NASA.

NASA historian Michael H. Gorn explores the vital human aspect of the history of flight research, including such well-known figures as James H. Doolittle, Chuck Yeager, and A. Scott Crossfield, as well as the less heralded engineers, pilots, and scientists who also had the "Right Stuff". While the individuals in the cockpit often receive the lion's share of the public's attention, Expanding the Envelope shows flight research to be a collaborative engineering activity, one in which the pilot participates as just one of many team members.

Here is more than a century of flight research, from well before the creation of NACA to its rapid transformation under NASA. Gorn gives a behind-the-scenes look at the development of groundbreaking vehicles such as the X-1, the D-558, and the X-15, which demonstrated mannedflight at speeds up to Mach 6.7 and as high as the edge of space.

First flown in 1969, Concorde was the first supersonic aircraft to go into commercial service in 1976 and made her final flight in 2003. She was operated primarily by British Airways and Air France. British Airways' Concordes made just under 50,000 flights and flew more than 2.5m passengers supersonically. A typical London to New York crossing would take a little less than three and a half hours compared to around eight hours for a `subsonic flight'. In November 1986 a Concorde flew around the world, covering 28,238 miles in 29 hours, 59 minutes. Today, Concordes can be viewed at museums across the UK and in France, including at IWM Duxford, Brooklands and Fleet Air Arm Museum, as well as at Heathrow, Manchester and Paris-Orly airports. However, there have been recent reports suggest that a Concorde may start operating commercially again. Through a series of key documents the book tells the story of how the aircraft was designed and developed as well as ground-breaking moments in her commercial history.

This updated edition includes fatigue and sleep definitions as well as strategies for the measurement and assessment of fatigue. The aviation performance, mood, and safety problems associated with sleep restriction and circadian disruptions in operational settings are highlighted. The biological bases of fatigue are discussed so that the reader can understand that it is a real physiological phenomenon and not 'just a state of mind'. Both traditional and newly-developed scientifically-valid countermeasures are presented, and a variety of data from diverse sources are included to provide readers with a 'toolbox' from which they can choose the best solutions for the fatigue-related problems that exist in their unique operational context. In addition, an essential overview of Fatigue Risk Management Systems is included to provide the basic structure necessary to build and validate a modern, integrated approach to successful fatigue management. The book is of interest to aviation crews in both civilian and military sectors--managers as well as pilots, flight crews, and maintainers. It aims to be user-friendly, although scientific information is included to help the reader fully understand the 'fatigue phenomenon' from an evidence-based perspective as well as to enhance the reader's appreciation for the manner in which various counter-fatigue interventions are helpful.

Introduction to Avionic Systems, Third Edition explains the basic principles and underlying theory of the core avionic systems in modern civil and military aircraft, comprising the pilot's head-up and head-down displays, data entry and control systems, fly by wire flight control systems, inertial sensor and air data systems, navigation systems, autopilots and flight management systems. The implementation and integration of these systems with current (2010) technology is explained together with the methods adopted to meet the very high safety and integrity requirements. The systems are analysed from the physical laws governing their behaviour, so that the system design and response can be understood and the performance examined. Worked examples are given to show how the theory can be applied and an engineering "feel" gained from a simplified model. Physical explanations are also set out and the text is structured so that readers can "fast forward" through the maths, if they so wish. Introduction to Avionic Systems, Third Edition meets the needs of graduates, or equivalent, entering the aerospace industries who have been educated in a wide range of disciplines, for example, electronic engineering, computing science, mathematics, physics, mechanical and aeronautical engineering. It also meets the needs of engineers at all levels working in particular areas of avionics who require an understanding of other avionic systems. Technology is continually advancing and this new third edition has been revised and updated and the presentation improved, where appropriate, The systems coverage has also been increased and a new section on helicopter flight control added.

The book provides a data-driven approach to real-world crew resource management (CRM) applicable to commercial pilot performance. It addresses the shift to a systems-based resilience thinking that aims to understand how worker performance provides a buffer against failure. This book will be the first to bring these ideas together.

Taking a competence-based approach offers a more coherent, relevant approach to CRM. The book presents relevant, real-world examples of the concepts and outlines a change in thinking around pilot performance and data interpretation that is overdue.

Airlines, pilots and aviation industry professionals will benefit from the insights into organisational design and alternative approaches to training.
