Diploma Thesis from the year 2012 in the subject Engineering - Aerospace Technology, grade: A, - (University of Zilina), course: Aviation, language: English, abstract: The economic situation of recent years forces to operate at highest payloads possible and therefore maximum allowable take-off masses of an aircraft. An optimization of the take-off performance plays important role as never before. The take-off performance data for several flight and ambient conditions are usually presented in so called runway analyses. This paper answers possible questions about their application and computing, which may interest a personnel of flight engineering departments or pilots. Moreover, this thesis offers a summary of factors affecting the maximum take-off mass and appropriate take-off speeds, which together represent necessary performance data for a safe take-off. Particular sections describe a principle of the optimization process and offer a designed conceptual model in a form of flowcharts according to which it is possible to perform a calculation for various aerodrome or weather conditions. The created conceptual model may also serve as a core for the software application, which reduces the time required to do the calculation manually.

A brand-new edition of the classic guide on low-speed wind tunnel testing While great advances in theoretical and computational methods have been made in recent years, low-speed wind tunnel testing remains essential for obtaining the full range of data needed to guide detailed design decisions for many practical engineering problems. This long-awaited Third Edition of William H. Rae, Jr.'s landmark reference brings together essential information on all aspects of low-speed wind tunnel design, analysis, testing, and instrumentation in one easy-to-use resource. Written by authors who are among the most respected wind tunnel engineers in the world, this edition has been updated to address current topics and applications, and includes coverage of digital electronics, new instrumentation, video and photographic methods, pressure-sensitive paint, and liquid crystal-based measurement methods. The book is organized for quick access to topics of interest, and examines basic test techniques and objectives of modeling and testing aircraft designs in low-speed wind tunnels, as well as applications to fluid motion analysis, automobiles, marine vessels, buildings, bridges, and other structures subject to wind loading. Supplemented with real-world examples throughout, Low-Speed Wind Tunnel Testing, Third Edition is an indispensable resource for aerospace engineering students and professionals, engineers and researchers in the automotive industries, wind tunnel designers, architects, and others who need to get the most from low-speed wind tunnel technology and experiments in their work.

Patterned after volumes in McGraw-Hill's "Time-Saver Standards" series in the architecture program (and Wiley's "Architectural Graphic Standards") and vastly expanding the range of the best-selling "Mechanisms and Mechanical Devices Sourcebook" by Chironis, this major new handbook presents a full array of key machine elements used in a wide range of applications. Filled with thousands of illustrations, it provides a quick-look-up resource of pictorial detail (worth many pages of text) for the busy engineer looking for the right device for the right application all systematically organized for easy access.

The development of clean, sustainable energy systems is one of the pre-eminent issues of our time. Most projections indicate that combustion-based energy conversion systems will continue to be the predominant approach for the majority of our energy usage, and gas turbines will continue to be important combustion-based energy conversion devices for many decades to come, used for aircraft propulsion, ground-based power generation, and mechanical-drive applications. This book compiles the key scientific and technological knowledge associated with gas turbine emissions into a single authoritative source. The book has three sections: the first section reviews major issues with gas turbine combustion, including design approaches and constraints, within the context of emissions. The second section addresses fundamental issues associated with pollutant formation, modeling, and prediction. The third section features case studies from manufacturers and technology developers, emphasizing the system-level and practical issues that must be addressed in developing different types of gas turbines that emit pollutants at acceptable levels.

Aviation fuel hydrant systems at airports are the penultimate step in the delivery chain of aviation fuel into aircraft. It is therefore imperative to ensure that the quality and cleanliness of the jet fuel in the hydrant is maintained at all times. This publication has been developed to assist in the optimisation of hydrant system operations. It provides recommended practices for operational checks, inspections and maintenance procedures to ensure aviation fuel quality assurance and cleanliness standards are met. It also provides recommendations for associated equipment, from pump sets to hydrant pit valves and for those undertaking routine checks and inspections of such equipment. This publication is applicable to owners, operators and users of aviation fuel hydrant systems at airports worldwide. It will also be of interest to procurement managers of equipment and materials for hydrant system inspection, maintenance and checking purposes, including service providers. Hydrant system designers will also find this publication useful as background information on the expectations of hydrant system owners and operators. This publication includes a free A3 annual planner pull-out/separate downloadable pdf.

Modelling and Managing Airport Performance provides an integrated view of state-of-the-art research on measuring and improving the performance of airport systems with consideration of both airside and landside operations. The considered facets of performance include capacity, delays, economic costs, noise, emissions and safety. Several of the contributions also examine policies for managing congestion and allocating sparse capacity, as well as for mitigating the externalities of noise, emissions, and safety/risk. Key features: * Provides a global perspective with contributing authors from Europe, North and South America with backgrounds in academia, research institutions, government, and industry * Contributes to the definition, interpretation, and shared understanding of airport performance measures and related concepts * Considers a broad range of measures that quantify operational and environmental performance, as well as safety and risk * Discusses concepts and strategies for dealing with the management of airport performance * Presents state-of-the-art modelling capabilities and identifies future modelling needs Themed around 3 sections -- Modelling Airport Performance, Assessing Airport Impacts, and Managing Airport Performance and Congestion -- Modelling and Managing Airport Performance is a valuable reference for researchers and practitioners in the global air transportation community.

"Aviation Logistics" demonstrates and explains how the rapidly evolving global logistics industry works in close partnership with the aviation operators to achieve fast and efficient facilitation. It examines the different sectors of products used by air freight and how carriers are responding to market demands with new and better methods and technologies.Technology and its resulting efficiency and transparency are a central part: for example, the adoption of electronic processing systems, screening of cargo, new warehousing technologies and the ability to track shipments through the system, are facilitating faster deliveries and reducing loss. Global markets and economies are constantly evolving and the supply chain business with its transport partners must be proactive for the future."Aviation Logistics" also reviews the changes in manufacturing and production methods -- these will be illustrated by case studies which will illustrate how different challenges are met in varied markets.
