In view of the many positive comments by the participants of all former AST workshops, the TUHH team was fully motivated to organize the 6th International Workshop on Aircraft System Technologies AST 2017. The proceedings of the workshop comprise 40 high-quality contributions which were selected from a call for papers. The contributions presented at the workshop address the fields of Airframe Systems and Equipment, Cabin and Comfort, Information and Communication Management as well as Materials and Production. In the first chapter dealing with Airframe Systems and Equipment, topics such as flight control, electromechanical actuator technology, health monitoring as well as ice protection and landing gear systems are discussed. Additional papers are related to special areas, such as power system design, resonance effects, virtual testing, rotary gear development, model-based systems engineering or active flow control. The topics with respect to Cabin and Comfort are treated in the second chapter. The work in this chapter focuses on cabin interior acoustics, climate control / thermal comfort and lightweight structures, including special topics like, e. g., active structural acoustic control. Chapter three Information and Communication Management covers different aspects of future cabin networks, wireless data transmission as well as avionics devices and software platforms. Actual topics like modular architectures and near field communication are discussed with respect to an application inside the aircraft cabin. The last chapter is devoted to Material and Productions. On the one hand, several contributions dealing with efficient production techniques, especially concerning additive manufacturing and composite materials, as well as automatization methods are included. On the other hand, topics related to inspection, damage location, and nondestructive testing are covered. For practicing engineers and scientists working in one of these areas, the proceedings will be a valuable source of information.

After the very successful events in 2007 and 2009, the Hamburg University of Technology has been fully motivated to arrange the 3rd International Workshop on Aircraft System Technologies AST 2011, and again the organizers cordially welcome you to this extraordinary event of the aircraft community. Well-known international experts from industry, research institutes, and universities are meeting in Hamburg, one of the world’s leading centers for civil aviation. Here R& D activities are promoted in different ways, for instance, by the joint initiative “Hamburg – The place for aviation” or by the “Luftfahrtcluster Metropolregion Hamburg”, a German “Spitzencluster” sponsored by the Federal Ministry of Education and Research. The latter has been led to a unique collaborative network, where industry, universities, and government work closely together on innovative ideas and developments in the field of future aircrafts. Major objectives are to strengthen the region, to further improve employment, and to support Hamburg’s worldwide recognition.

Following the demand of many scientists, experts, and leading companies, the Hamburg University of Technology organized the 2nd International Workshop on Aircraft System Technologies AST 2009.
