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.

Clean Sky 1 activities
Workshop on Clean Sky 2,March 15th 2013, Brussels
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 (CO2, 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.

APPLICATION EXAMPLE: Prediction of the increase in delaminated
area DA as a function of the applied load for delaminated composite
stiffened panels under compression Comparisons among the
developed E-SMXB model, standard Abaqus and experimental data
(graph on the right) point out the added value of the developed model
with respect to standard commercial tools.
• Integration of the models in commercial Finite Element
codes by user subroutines.
• Validation by comparison with thermography images of the
delaminated area taken during the application of the
mechanical load
