Abstract	The Aviation Cluster of the Hamburg Metropolitan Region is Germany’s leading industry cluster. With its integrated strategy for “A New Kind of Aviation”, the Hanseatic aviation industry emerged out of the nation-wide, cross-sectorial competition of 38 industry clusters as one of five winners to share federal support. The new cluster strategy incorporates three milestone projects: “Cabin technology and innovative fuel cell applications”, “Extended MRO competence for new aircraft generations” and “Efficient airport 2030”. The Hamburg University of Technology (TUHH) is one of the youngest universities in Germany as well as one of the most successful. The fundamental principles of the TUHH are unique in Germany; priority is given to research, interdisciplinary studies and innovation. Also central to our approach is a close working relationship with regional industries and, more recently, the achievement of international scale. Frank Thielecke is head of the Institute of Aircraft Systems Engineering which is part of the department of mechanical engineering. The Institute is located in the Technology Centre Hamburg-Finkenwerder which is a very positive example of public-private partnership between AIRBUS and TUHH. The Institute of Aircraft Systems Engineering is focusing on mechatronic aircraft systems and new technolo-gies for the future More-Electric-Aircraft. Today’s basis aircraft systems for electronic flight control and actua-tion, landing gears, on-board energy generation as well as cooling are characterized by increasing levels of au-tomation, fault tolerance, performance optimization and new innovative functions. Due to the increasing design complexity and multi-disciplinarily, a strong need for integrated design processes, computer-aided tools, as well as virtual integration platforms is identified. Current research topics and on-going projects are: (1) Project: Nonlinear Observer Implementation and Validation for Empennage Loads Estimation • Detection of load relevant events and optimization of the inspection • Assessment of ageing condition and optimization of maintenance • Verification of design • Basis for load alleviation systems Main Objectives at the TUHH Institute of Aircraft Systems Engineering • Validation of the Loads Observer method • Development of further approaches • Comparison and assessment of different methods (2) Project: Electro-Mechanical Actuation in Flight Control Systems • Need for new methods to enhance the design and development process of EMAs in flight control systems • Design challenges are : Multi-domain system, High reliability required / Safety features, Exposure to extreme environmental conditions, Coupling of power demand and thermal effects, Strict toler-ances in mechanical components Main Objectives at the TUHH Institute of Aircraft Systems Engineering • Preliminary design of EMAs with PreDEMA library sizing models • Rapid analysis of system configurations and new component technologies • System-level evaluation under parametric uncertainties • Triggering of steady-state simulations through sizing algorithm • Solution of interval constraint satisfaction problem • Optimization of selected parameters • Dynamic simulation at system level: verification of requirements • Uncertainties are carried over and used for the design of control and monitoring functions The Institute is located in the Technology Center Hamburg Finkenwerder and operates a broad spectrum of test facilities and demonstrators.
