3 DIII profile and skills Established in 2012 from Department of Aerospace and Mechanical Engineering + Department of Information Engineering, Strategic areas Aerospace and Mechanical Engineering Automation and Computer Science Electronics (Signal + Power) Telecommunication Other fields of interests are Electrical Engineering, Chemical Engineering and Material Science, and close areas of applied Physics, Chemistry and Statistical Sciences.

4 DIII profile and skills MOET FP6 Project BBCU The BBCU (Buck Boost Converter Unit) is a bidirectional DC/DC converter able to deliver 6kW at low-voltage (i.e. 28V) side in Buck (or step-down) mode, and 12kW at high-voltage (i.e. 270V) side in Boost (or step-up) mode. BBCU is a cellular converter, where all the four cells are connected to each other in PIPO mode (Parallel Input, Parallel Output). The interleaving technique is used to reduce components size, (in particular the size of the inductor), current ripple, reduce EMI and to improve the reliability. Each cell is a boost full bridge converter, rated at 3kW.

12 Clean Sky 1 activities Green Regional Aircraft Simulation Model (GRASM) In the frame of CLEAN SKY GRA ITD NC Domain, DIII developed a specific numerical model (GRASM) simulating aircraft trajectories during typical flight mission segments, providing estimation of noise levels and pollutants emitted by the aircraft during flight paths. GRASM Main Objectives: To simulate specific mission profiles and/or fixed departure/arrival trajectories providing aircraft and engine operational parameters on each flight segment. To estimate noise parameters during relevant flight mission segments taking into account aircraft aerodynamic and propulsion characteristics as well as ambient parameters. To estimate pollution levels emitted during each flight segment and to evaluate environmental impact according to selected Pollution indexes (CO 2, NOx). GRASM possible future application: To simulate departure/arrival trajectories compliant with standard air traffic control rules to evaluate aircraft noise and pollutant emissions in real operational scenarios.
