Green Aviation is the first authoritative overview of both engineering and operational measures to mitigate the environmental impact of aviation. It addresses the current status of measures to reduce the environmental impact of air travel. The chapters cover such items as: Engineering and technology-related subjects (aerodynamics, engines, fuels, structures, etc.), Operations (air traffic management and infrastructure) Policy and regulatory aspects regarding atmospheric and noise pollution. With contributions from leading experts, this volume is intended to be a valuable addition, and useful resource, for aerospace manufacturers and suppliers, governmental and industrial aerospace research establishments, airline and aviation industries, university engineering and science departments, and industry analysts, consultants, and researchers.

Aircraft emissions currently account for ~3.5% of all greenhouse gas emissions. The number of passenger miles has increased by 5% annually despite 9/11, two wars and gloomy economic conditions. Since aircraft have no viable alternative to the internal combustion engine, improvements in aircraft efficiency and alternative fuel development become essential. This book comprehensively covers the relevant issues in green aviation. Environmental impacts, technology advances, public policy and economics are intricately linked to the pace of development that will be realized in the coming decades. Experts from NASA, industry and academia review current technology development in green aviation that will carry the industry through 2025 and beyond. This includes increased efficiency through better propulsion systems, reduced drag airframes, advanced materials and operational changes. Clean combustion and emission control of noise, exhaust gases and particulates are also addressed through combustor design and the use of alternative fuels. Economic imperatives from aircraft lifetime and maintenance logistics dictate the drive for "drop-in" fuels, blending jet-grade and biofuel. New certification standards for alternative fuels are outlined. Life Cycle Assessments are used to evaluate worldwide biofuel approaches, highlighting that there is no single rational approach for sustainable buildup. In fact, unless local conditions are considered, the use of biofuels can create a net increase in environmental impact as a result of biofuel manufacturing processes. Governmental experts evaluate current and future regulations and their impact on green aviation. Sustainable approaches to biofuel development are discussed for locations around the globe, including the US, EU, Brazil, China and India.

Seminar paper from the year 2015 in the subject Engineering - Aerospace Technology, grade: 1,0, University of Applied Sciences Frankfurt am Main, language: English, abstract: The purpose of this paper is to evaluate the challenges and chances of biofuels in an aviation context. It begins by providing a brief history on biofuels in general and in aviation specifically. It is followed by an overview of the main driving forces for the aviation industry to invest in biofuels and their development. After that, different available biofuels and their segmentation in first, second, and third generations is shown in more detail along with a basic overview on the production processes that exist on the market. Based on the given information, first the challenges and after that, the chances, for the aviation industry on investing in aviation biofuels is shown into detail. The paper claims that the biofuels still have major issues as there is no real alternative on the market or in development that can substitute crude oil-based jet fuel up to 100%. Current biofuels can only be used as mixtures with conventional jet fuel. However, the biggest issue, namely that biofuels cannot be certified in aviation because of their specifications, is solved with second-generation biofuels. The main challenges are still to find a sustainable biofuel that can be used without changes to existing aircraft propulsion technology and nothing ensures that this will be possible in the necessary timeframe until the crude oil finally starts to become less available. That point in time is constantly updated, but only based on statistical data. It is not known at what point in time this will be exactly. However, there are a number of opportunities. They range from having an alternative to substitute conventional jet fuel for emission reduction reasons to the investment of an aircraft operator to the production of biofuel itself. This could be for the sake of entering new markets or just to integrate the

Global Warming: Causes, Impacts and Solutions covers all aspects of global warming including its causes, impacts, and engineering solutions. Energy and environment policies and strategies are scientifically discussed to expose the best ways to reduce global warming effects and protect the environment and energy sources affected by human activities. The importance of green energy consumption on the reduction of global warming, energy saving and energy security are also discussed. This book also focuses on energy management and conservation strategies for better utilization of energy sources and technologies in buildings and industry as well as ways of improving energy efficiency at the end use, and introduces basic methods for designing and sizing cost-effective systems and determining whether it is economically efficient to invest in specific energy efficiency or renewable energy projects, and describes energy audit producers commonly used to improve the energy efficiency of residential and commercial buildings as well as industrial facilities. These features and more provide the tools necessary to reduce global warming and to improve energy management leading to higher energy efficiencies. In order to reduce the negative effects of global warming due to excessive use of fossil fuel technologies, the following alternative technologies are introduced from the engineering perspective: fuel cells, solar power generation technologies, energy recovery technologies, hydrogen energy technologies, wind energy technologies, geothermal energy technologies, and biomass energy technologies. These technologies are presented in detail and modeling studies including case studies can also be found in this book.

From humble beginnings in 1911 with floatplanes, by the 1930s, the US Navy possessed dirigibles and were introducing fighter planes. By the start of WW2, monoplane fighters were replacing bi-planes and a major aircraft carrier build was underway. Fighters such as the Grumman FLF Hellcat and Vought F4U Corsair were joined by carrier attack aircraft such as the Dauntless, Devastator and Helldriver. As well as carrier-borne aircraft, others operated from shorebases using both wheels and floats. Post WW2, jet aircraft took over from prop driven, and famous early examples were the Shooting Star and McDonnell Phantom, which saw action in Korea. By Vietnam the F4 Phantom II, Skyhawk and Intruder were in service. As well as these fighter attack aircraft were the Lockheed Viking, anti-sub and nuclear capable Douglas Skywarrior. Post Vietnam the F14 Tomcat and Hornet came into service along with the Prowler (Electronic warfare) and Hawkeye (early warning). These aircraft were complemented by a range of helicopters from the massive Super Stallion, through Sea Kings, Seasprites and Seahawks. Today the Super Hornets predominates along with an impressive multi-capable range of aircraft and helicopters. All these and more are described in expert detail and illustrated in this fine book. Future projects are also covered.

Ernsting's Aviation and Space Medicine applies current understanding in medicine, physiology and the behavioural sciences to the medical challenges and stresses that are faced by both civil and military aircrew, and their passengers, on a daily basis. The fifth edition of this established textbook has been revised and updated by a multi-disciplinary team of experienced contributors, and includes new chapters on space physiology and medicine, passenger safety, rotary wing operation by land and sea, and UAVs. It remains the recommended textbook for those studying for the Diploma in Aviation Medicine of the Faculty of Occupational Medicine of the Royal College of Physicians, recognized worldwide as a standard in the field, and for similar overseas qualifications. Ernsting's Aviation and Space Medicine remains an essential companion for all civil and military aviation medicine practitioners, both when preparing for professional examinations and in daily practice, and for those in the many disciplines of the behavioural and life sciences that include some study of aviation, its physiology and related issues. It is also recommended reading for those with a wider interest in the medical problems of professional or recreational flying, air transport and the aviation industry.
