Airplane Performance on Grass Airfields presents an experiment-based approach to analysis and flight testing of airfield performance on grass runways. It discusses improvements for operations efficiency and safety of these airfields. The book analyzes the interaction between the landing gear wheels and the surface of a grass runways during both takeoff and landing. Considering the ground performance of an aircraft on a grass runway, the book covers test methods and devices for measuring performance and introduces an information system for the surface condition of grass airfields: GARFIELD. The system is based on a tire-grass interaction model and uses digital soil maps, as well as current meteorological data obtained from a weather server. The book is intended for researchers and practicing engineers in the fields of aviation and aircraft safety and performance.

'Thrilling ... High-definition history: tight, thrilling and beautifully researched' SUNDAY TIMES 'This book is a triumph' DAN SNOW 9.07 a.m., April 12, 1961. A top-secret rocket site in the USSR. A young Russian sits inside a tiny capsule on top of the Soviet Union's most powerful intercontinental ballistic missile - originally designed to carry a nuclear warhead - and blasts into the skies. His name is Yuri Gagarin and he is about to make history. Travelling at almost 18,000 miles per hour - ten times faster than a rifle bullet - Gagarin circles the globe in just 106 minutes. While his launch begins in total secrecy, within hours of his landing he has become a world celebrity - the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its sixtieth anniversary. It happened at the height of the Cold War as the US and USSR confronted each other across an Iron Curtain. Both superpowers took enormous risks to get a man into space first - the Americans in the full glare of the media, the Soviets under deep cover. Both trained their teams of astronauts to the edges of the endurable. In the end the race between them would come down to the wire. Drawing on extensive original research and the vivid testimonies of eyewitnesses, many of whom have never spoken before, Stephen Walker unpacks secrets that were hidden for decades and takes the reader into the drama - featuring the scientists, engineers and political leaders on both sides, and above all the American astronauts and their Soviet rivals battling for supremacy in the heavens.

The problem of fault diagnosis and reconfigurable control is a new and actually developing field of science and engineering. The subject becomes more interesting since there is an increasing demand for the navigation and control systems of aerospace vehicles, automated actuators etc. to be more safe and reliable. Nowadays, the problems of fault detection and isolation and reconfigurable control attract the attention the scientists in the world. The subject is emphasized in the recent international congresses such as IF AC World Congresses (San Francisco-1996, Beijing-1999, and Barcelona-2002) and lMEKO World Congresses (Tampere-1997, Osaka-1999, Vienna-2000), and also in the international conferences on fault diagnosis such as SAFEPROCESS Conferences (Hull-1997, Budapest-2000). The presented methods in the book are based on linear and nonlinear dynamic mathematical models of the systems. Technical objects and systems stated by these models are very large, and include various control systems, actuators, sensors, computer systems, communication systems, and mechanical, hydraulic, pneumatic, electrical and electronic devices. The analytical fault diagnosis techniques of these objects have been developed for several decades. Many of those techniques are based on the use of the results of modem control theory. This is natural, because it is known that fault diagnosis process in control systems is considered as a part of general control process. xxii In organization of fault diagnosis of control systems, the use of the concepts and methods of modem control theory including concepts of state space, modeling, controllability, observability, estimation, identification, and filtering is very efficient.

Reducing Airline's Carbon Footprint is the answer to the airline executives' problems, when it comes to looking for ways to reduce aircraft operations cost. Reducing Airline's Carbon Footprint introduces the Electric Taxi System, ETS. When commercial aircrafts are equipped with this system, the cost of operation will be reduced due to taxi without the main engines running. Also, the aircraft engines will not be ingesting foreign object debris (FOD) causing damage to the internal moving parts, and the airport area air pollution will see a decrease. This is the grey cloud that hovers over most busy airports. Reducing Airline's Carbon Footprint breaks through this cloud by providing ETS as the solution. Throughout its pages, Dr. Thomas F Johnson addresses these benefits of ETS: Improvement of Airport Area Air Quality Reduce aircraft carbon footprint Potential Costs of ETS Installation Fuel Consumption Evaluation before and after ETS installation Ground Taxi Time Evaluation Improved Airport Terminal Accessibility Landing Gear Compatibility for the ETS Installation

While monitoring of computer-controlled systems is widespread, it is critically important in the cockpit of current passenger aircraft. Such monitoring requires special vigilance for those rare untoward events, which may be new to the pilot and which can have devastating consequences. This book uses a multidisciplinary approach to address this problem of sustaining attention while monitoring. It outlines and explains alternative ways of viewing the processes needed to prevent Human Factors accidents; it examines the use and limitations of cockpit resource management programmes in inducing behavioural and attitudinal changes appropriate for highly automated flight decks. The author's approach deals rigorously with the physiological mechanisms underlying vigilance, arousal and stress, delineating clearly those that are relevant to the monitoring function. The three parts cover: monitoring problems and processes; monitoring measurement and alerting systems; and monitoring management. In the last part the author details management plans and guidance for monitoring assisted systems based on his understanding of the problems of continued human vigilance. Readership: pilots and training pilots; cockpit resource management groups; monitoring management specialists; university aviation departments; road and rail transport groups; those operating nuclear and large process installations.

In this Element, the gas-particle flow problem is formulated with momentum and thermal slip that introduces two relaxation times. Starting from acoustical propagation in a medium in equilibrium, the relaxation-wave equation in airfoil coordinates is derived though a Galilean transformation for uniform flow. Steady planar small perturbation supersonic flow is studied in detail according to Whitham's higher-order waves. The signals owing to wall boundary conditions are damped along the frozen-Mach wave, and are both damped and diffusive along an effective-intermediate Mach wave and diffusive along the equilibrium Mach wave where the bulk of the disturbance propagates. The surface pressure coefficient is obtained exactly for small-disturbance theory, but it is considerably simplified for the small particle-to-gas mass loading approximation, equivalent to a simple-wave approximation. Other relaxation-wave problems are discussed. Martian dust-storm properties in terms of gas-particle flow parameters are estimated.

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.
