A drive to improve thermal and propulsive eff iciencies still promises significant improvements. Bio-mix “drop-in” f uels are likely in the next 20 years and offer further improvements. In th e longer term\, we are likely to see a shift to distributed propulsion to further improve both propulsive efficiency and air frame performance. This may result in a few very high efficiency generators\, to drive a large nu mber of small electrically-driven fans.\n\nSuch a scenario opens up the po ssibility of significant advances by the ability to have “clean air fram es”. In the long term\, the growth of civil aviation may have to be cur tailed\, in spite of growing market demand. A way forward could be the com bination of hydrogen and other technologies\, including the intriguing pos sibility of an aircraft being able to produce global warming or cooling at will\, perhaps allowing mankind to control the earth’s temperature by t he use of civil aviation.\n\n*Riti Singh* is Professor Emeritus of Cranfie ld University. He leads the Gas Turbine Engineering & Technology Group wit hin the Department of Power and Propulsion and is Director of the Rolls-Ro yce University Technology Centre in Performance Engineering. Professor Sin gh has given many plenary/keynote speeches. He holds numerous patents\, an d has published widely. His research has been strongly supported by indust ry\, the European Union and EPSRC.\n\nHe has an interest in novel cycles f or power and propulsion\, particularly in the context of the environment. Professor Singh was awarded the ASME International Gas Turbine Institute ’s Annual International Aircraft Engine Technology Award for 2010\, pres ented to one individual each year for sustained\, innovative personal cont ribution to the field. Other recent awards include the ASME IGTI (2004) “Cycles Innovations Committee Best Paper Award”\, the Royal Aeronautic al Society’s Silver Award (2006)\, the Ackroyd Stuart Prize\, and the AS ME IGTI (2010)\, “Cycles Innovations Committee Best Paper Award”. He i s a Board member of the Aerospace Industries Board\, Institution of Mechan ical Engineers and the International Society of Air Breathing Engines (ISA BE).\n\nProfessor Singh has consulted for over 40 organizations\, includin g gas turbine manufacturers and users in over 20 countries.\n\nThe talk wi ll start at 18:00. Refreshments will be served from 17:15. Those travell ing from Cambridge are invited to contact charles.lee@futureneering.com to share lifts.
