Abstract	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 re-search, 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 Insti-tute 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 part-nership between AIRBUS and TUHH. The Institute of Aircraft Systems Engineering is focusing on mechatronic aircraft systems and new technologies for the future More-Electric-Aircraft. Today’s basis aircraft systems for electronic flight control and actuation, landing gears, on-board energy generation as well as cooling are characterized by increasing levels of automation, 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. ZAL – Hamburg’s Center of Applied Aeronautical Research – is the technological research and development network of the civil aviation industry in the Hamburg Metropolitan Region. It functions as an interface between academic & research institutions, the aviation sector, and the City of Hamburg, aimed at securing and continually expanding the world’s third largest civil aviation location in Hamburg. Working together closely with the aviation cluster, Hamburg Aviation, ZAL bundles the technological competence of the city in a single facility, the ZAL TechCenter, thereby creating synergy. ZAL’s focus is on the integration and industrialization of aviation technolo-gies. To achieve this, ZAL networks industry and science, establishing an application-oriented think-tank culture, and making the very latest research and development infrastructure available to its partners. In this way, fusing the specific expertise of its partners, ZAL supports the widest range of research and development projects in the field of civil aviation – projects that are jointly owned and jointly developed by all participants working together as partners. The constant focus on the latest technological developments means that ZAL is the birthplace of vision-ary ideas. After a lengthy development and test phase, these ideas grow into innovative products for the interna-tional aviation industry. Current on-going projects are: (1) PBL Teaching >> Systems Engineering Project for Students • Project-based learning is a dynamic teaching approach in which students actively explore real-world problems and challenges and acquire a deeper knowledge. The core idea of project-based learning is that real-world problems capture students' interest and provoke serious thinking as the students acquire and apply new knowledge in a problem-solving context. It emphasizes learning activities that are long-term, interdisciplinary and student-centered. The teacher plays the role of facilitator! • Design-Build-Fly Concept was focusing on a high-aspect ratio wing with distributed electrical propulsion and a body landing gear concept • First Flight: good flying qualities, flight performance as predicted • Second Flight: Loss of aircraft caused by flutter • On-going project: Modeling, analysis and testing of aeroelastic effects (2) Project G-Flights: Loads Protected Aircraft • Combination of different control tasks and flight control optimization • model predictive autopilot (MPAP) for flight path control within load limits • flight path relaxation in case of reaching limit load • loads measurement system: IMU: accelerations and rates, strain gauges: shear force, bending and torsion (3) Project ULTRA Autoland and Autotaxiing • Nonlinear model of A/C and dynamic environment • Path Planning & Path Following: Bidirectional A*-algorithm, Orientation correction Path smoothing us-ing B-splines, Non-Linear Guidance Law • Control: Speed and heading, Wheel steering based on PI-control, Speed reduction during curves, Differ-ential braking for narrow curves • Satisfying tracking performance for mean wind speeds up to 15 m/s and other disturbances (4) Project AVIONICS: An Easy-to-use Real-time AFDX Simulation Framework • Avionics effects in systems become more and more important!, e.g. delay, jitter, routing, configuration errors • Real avionics hardware is expensive and complex to operate, Strong desire for an easy-to-use avionics simulation, start with the simulation of AFDX networks • Needed: Functional behavior, Sequences and timings in real-time, Applicable by non-computer scientists, building arbitrary virtual topologies, Connection of real AFDX equipment or networks • Successful Demo for A380 AFDX: 93 End-systems, 8 Switches, 186 Frames @ 1kHz, Maximum frame size reduced to 150 Byte (1:10), Simulation runs in real-time The Institute is located in the Technology Center Hamburg Finkenwerder and operates a broad spectrum of test facilities and demonstrators.
