11/2007 - 02/2008: Aerodynamicist - Airbus Deutschland (GCT-GED Group) - Bremen (Germany)

Analysis of the A350-XWB high-lift devices aerodynamic loads based on low speed wind tunnel data for longitudinal motion, spoiler and aileron and configuration effects.

- Identification and correction of false pressure data.
- Comparisons of wind tunnel analysis with CFD calculations for various Reynolds numbers.
- Use of several Fortran-based codes – Modifications according to new input formats.
- Write-up of a wind tunnel analysis report and delivery of final data.
4 month contract – Involves working under pressure in order to fulfil the customer requirements in terms of data integrity and delivery.



06/2005 - 10/2007: R&D Engineer - Airbus España (Aeroconseil Iberica) - Getafe (Spain)

• NEFA (New Empennage For Aircraft) R&D program:
Investigation of the longitudinal and lateral aerodynamic characteristics of an Airbus “V-Tail” tailplane under various flight conditions (low-speed and high-speed, take-off, cruise and landing) and aircraft configurations (slats/flaps extended or retracted, symmetrical/asymmetrical/anti-symmetrical elevator deflections).
- To define an aerodynamic model of the main force and moment coefficients, taking into account the aerodynamic phenomena such as downwash and dynamic pressure loss.
- To compare the efficiencies of the V-tail with the conventional HTP/VTP concept.
- General aerodynamic modelling (stalling angle, non-linearity, etc.) and analysis of the left and right tail interaction as a function of various elevator angle configurations.

• REFUTA R&D program:
Tail pressure coefficient analysis and aerodynamic load distribution according to different wing load distributions, taking into account the downwash effect. Pressure corrections and investigation of the distribution due to different wing planforms.
Frequent use of Fortran and Matlab. Code interface improvement.



12/2003 - 06/2005: Aerodynamics Engineer - Stirling Dynamics Ltd - Bristol (UK)

• Calculation and analysis of aerodynamic loads on the Airbus A320 and A380 slats and droop noses for several flight configurations (slats extended/retracted, fatigue missions, jamming, etc). Comparisons with previous wind tunnel campaigns.
• Performance prediction (aerodynamic loads, dynamic behaviour) of the Eurofighter Typhoon towed decoy for different flight cases involving complex manoeuvres. Optimisation investigation of the results analysis.
Project with BAE Systems.
Responsibility for the validity and coherency of the data delivered to the customer. Flexible approach to changing situations. Frequent use of Matlab and its GUI (Graphical User Interface).
