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.

Green Regional Aircraft Simulation Model (GRASM)

ACTIVITY: Development and experimental validation of numerical models for the simulation of impact induced

delaminations onset and evolution in composite structures under service loading conditions.

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
