This book offers the first complete account of more than sixty years of international research on In-Flight Simulation and related development of electronic and electro-optic flight control system technologies (“Fly-by-Wire” and “Fly-by-Light”). They have provided a versatile and experimental procedure that is of particular importance for verification, optimization, and evaluation of flying qualities and flight safety of manned or unmanned aircraft systems. Extensive coverage is given in the book to both fundamental information related to flight testing and state-of-the-art advances in the design and implementation of electronic and electro-optic flight control systems, which have ma...
From the early machines to today's sophisticated aircraft, stability and control have always been crucial considerations. In this second edition, Abzug and Larrabee again forge through the history of aviation technologies to present an informal history of the personalities and the events, the art and the science of airplane stability and control. The book includes never-before-available impressions of those active in the field, from pre-Wright brothers airplane and glider builders through to contemporary aircraft designers. Arranged thematically, the book deals with early developments, research centers, the effects of power on stability and control, the discovery of inertial coupling, the challenge of stealth aerodynamics, a look toward the future, and much more. It is profusely illustrated with photographs and figures, and includes brief biographies of noted stability and control figures along with a core bibliography. Professionals, students, and aviation enthusiasts alike will appreciate this readable history of airplane stability and control.
New competitive realities have ruptured industry boundaries, overthrown much of standard management practice, and rendered conventional models of strategy and growth obsolete. In their stead have come the powerful ideas and methodologies of Gary Hamel and C.K. Prahalad, whose much-revered thinking has already engendered a new language of strategy. In this book, they develop a coherent model for how today's executives can identify and accomplish no less than heroic goals in tomorrow's marketplace. Their masterful blueprint addresses how executives can ease the tension between competing today and clearing a path toward leadership in the future.

Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence. Physical models are very effective at revealing issues that are sometimes not correctly identified in the virtual domain, and hence can be a valuable complement to other design tools. But traditional wind-tunnel testing cannot always meet all of the ...

Rapid developments of computer technology have affected the analysis, synthesis, and control of every aspect of aerospace vehicle dynamics. The rewards of increased research have had far reaching implications in terms of performance, safety, and operational cost effectiveness. New challengeshave emerged in the wake of the recent shift in emphasis from military to civil applications. This collection of papers covers a wide range of topics including mathematical modelling, compuational methods, computer simulation, and developments in control systems.To sum up, this is an interesting and topical selection of papers on recent research in an area of growing interest and application.
The Battle of Le Hamel on 4 July 1918 was an Allied triumph, and strategically very important in the closing stages of WW1. A largely Australian force commanded by the brilliant John Monash, fought what has described as the first modern battle - where infantry, tanks, artillery and planes operated together, as a coordinated force. Monash planned every detail meticulously - with nothing left to chance: integrated use of planes, wireless (and even carrier pigeons!)was the basis, and it went on from there, down to the details. Infantry, artillery, tanks and planes worked together of the battlefront, with relatively few losses. In the words of Monash: 'A perfect modern battle plan is like nothing so much as a score for an orchestral composition, where the various arms and units are the instruments, and the tasks they perform are their respective musical phrases.'
