IFAR meetings related to topics. 4. Aviation research - state of the art 4.1 History Over the past 100 years aviation has transformed the society dramatically. Looking back at the last 50 years the aviation passed a spectacular development. The International Energy Agency IEA developed the graph in Fig. 3 which shows for that time the improvement of the energy intensity fuel burn per passenger kilometre for selected aircraft. This figure illustrates that the technology in engine airframe and other measures has helped to reduce the aircraft fuel burn per passenger kilometre by more than 70 . This is already an excellent success. However a significant growth of the Air Traffic System cf. next section is expected in the next years. Due to the negative impact on the climate and the decreasing availability of fuel resources there is still a high demand for a further improvement of the energy intensity. It is the responsibility of the aviation research to develop the corresponding new technologies as well as looking into alternative fuels. 4.2 Outlook into the future 4.2.1 General CO2 forecast IEA published in 2010 the Energy Technology Perspectives - Scenarios and strategies to 2050. This report ETP 2010 analyses and compares various scenarios. It does not aim to forecast what will happen but rather to demonstrate the many opportunities to create a more secure and sustainable energy future. A comparison of different scenarios demonstrates that low-carbon technologies can deliver a dramatically different future. However it is mandatory not only to stimulate the evolutionary development of new IFAR - The International Forum for Aviation Research 339 C10-4C B747-200 300 DC 0-10 B747-10Ũ LIO -SOOTr star MD80 DC9-8C A310-300 B737-30Ũ B737-400 8737-500 600 B707-100B B707-300B B767-200 200E A300-600 R CF RC A320-100 200 8757-200 B767-300 300ER JC9-4C 8727-200 23 A 3737 WQ 200 Fig. 3.
