Selected Issues In Exhaust Emissions From Aviation Engines

Works related to identification of harmful exhaust components from aviation engines have continued since the second half of the last century. These works focus on high-thrust turbine engines. For this, group testing and standardization procedures have been developed containing the admissible limits of exhaust components. Since 2007 works have been underway related to the identification of harmful exhaust components from engines of low power output that have not yet been included in the emissions legislation. These actions are particularly related to the measurements of the exhaust emissions from piston aviation engines and they are focused on the fuel applied for these engines. This book presents the results of the author's own research work related to the issues of exhaust emissions from powertrains of aircraft and helicopters fitted with piston or turbine engines not yet included in the emission legislation. Research has been presented for turbocharged piston and jet engines aircraft. Test procedures have been presented related to the measurement of the exhaust emission under actual conditions of operation. The study presents analyses of the operating conditions of aviation engines, for which data from the on-board recording devices (flight parameters) have been used. Tests have been developed related to the engines operating under actual operating (in-flight) conditions. The methodology of the developed test has been validated based on a test dedicated for an aircraft fitted with a jet engine. The test results have been subject to a comparison with the results of tests applicable in the homologation procedures. Eventually, the authors proposed exhaust emissions tests dedicated to individual aircraft groups.

'This is a timely, challenging and fascinating book on a topic of central importance to the success or otherwise of our climate change policies. It sets down a clear marker for what has to be done in the aviation sector.' Professor John Whitelegg, Stockholm Environment Institute, University of York, UK 'Climate Change and Aviation presents a clear picture of the transport sector's greatest challenge: how to reconcile aviation's immense popularity with its considerable environmental damage and its dependence on liquid hydrocarbon energy sources. This book avoids wishful thinking and takes the much harder, but more productive, path of considering difficult solutions that clash with short-term and short-sighted expectations about the unlimited growth potential for flying.' Professor Anthony Perl, Urban Studies Program, Simon Fraser University, Canada 'A convincing and timely collection that brings together an impressive range of expertise. The book integrates various perspectives into a powerful core argument - we must do something, and quickly, to tackle the impact of aviation on our environment. The authors recognise the political difficulties associated with promoting change but present constructive options for policy makers. Required reading, especially for transport ministers set on promoting the growth of air travel.' Professor Jon Shaw, Director of the Centre for Sustainable Transport, University of Plymouth, UK Trends such as the massive growth in availability of air travel and air freight are among those which have led to aviation becoming one of the fastest growing emitters of greenhouse gases. These trends have also caused a shift in expectations of how we do business, where we go on holiday, and what food and goods we can buy. For these reasons aviation is (and is set to stay) high up on global political, organizational and media agendas. This textbook is the first to attempt a comprehensive review of the topic, bringing together an international team of leading scientists. Starting with the science of the environmental issues, it moves on to cover drivers and trends of growth, socio-economics and politics, as well as mitigation options, the result being a broad yet detailed examination of the field. This is essential reading for undergraduate and postgraduate courses in transport, tourism, the environment, geography and beyond, while also being a valuable resource for professionals and policymakers seeking a clear understanding of this complex yet urgently pressing issue.
