The majority of the world’s largest carbon emitters are either federations or have adopted systems of decentralised governance. The realization of the world’s climate mitigation objectives, therefore, depends in large part on whether and how governments within federal systems can cooperate to reduce carbon emissions and catalyze the emergence of low-carbon soci…
The Aviation Maintenance Technician Handbookâ€â€Airframe (FAA-H-8083-31B) is one of a series of three handbooks forpersons preparing for certification as an airframe or powerplant mechanic. This handbook provides basic information onprinciples, fundamentals, and technical procedures in the subject matter areas relating to the airframe rating.
There is a growing literature examining the decline in labor market status experienced by lesser-educated men in the past half century. Despite workplace advances in automation and rising real wages for most workers during much of this period, lesser-educated men have experienced declining employment rates and real wages, along with declining marriage rates.
The papers aim to contribute to a better understanding of problems and solutions of geotechnical nature, as well as to a more adequate management of natural resources. Case studies are included to better disseminate the success and failure of Geotechnical Engineering practice.
Exactly 100 years ago prof. Joukowsky, one of the founders of modern aerodynamics, published the first rotor performance prediction. The tools of Jankowsky and his contemporaries were mathematics and wind tunnel experiments, nowadays we use mathematics, numerics, full scale experiments and, still, wind tunnel experiments.
This illustrated history paper is one of a kind, as it is the first time that the history of Aerospace Engineering at Delft University of Technology is presented in English and embedded in a wider historical context.
Airservices Australia has a keen interest in and strong commitment to the history of Australian civil aviation and the vast and far-flung body of cultural and industrial heritage that this history has created. Pieces of what was once new fangled equipment, airport buildings, photographs, posters, uniforms, archives and oral histories, among other things, allow us to understand and appreciate th…
Despite intense development of computational technologies, achievements in the area of construction of numerical methods and development of commercial and open-source software, improvements of experimental methods, and high-performance computing facilities, the problem of modelling and simulation of turbulence remains one of the most complex and important problems of fluid dynamics.
The most important fact related with fluid motion is to understand the fluid patterns, and the flow structure †vortices, recirculation zones, high mix regions, poor mix regions, calm regions, to name a few. Moreover, most of the flows have turbulent characteristics and turbulence remains one of the unsolved problems in physics.
In the aerospace field, hypersonic flight plays a fundamental role. Some sixty years after the experimental flights of the North American X-15 hypersonic rocket-powered aircraft, sustained hypervelocity travel is still the next frontier in high-speed transportation.
