Activities, case study

Exchange programme

The four training centres at Leicester, Turin, Toulouse and Rome have established individually and independently successful high-quality graduate training schools for early stage researchers. Doctoral training in France, Italy and in the UK nominally lasts three years, making it possible for the four centres to propose this multi-host EST doctoral training programme. The proposed programme for early stage researchers brings original and innovative postgraduate training to these institutes by providing interaction among the trainees. The key innovation with respect to conventional student exchange programmes is that, in this scheme, students spends time working together in each centre, rather than moving around independently as working individuals. Being able to work together with a fellow early stage researcher adds an original, innovative and very valuable element to the doctoral training currently offered by the four training centres. Specifically, early stage researchers can integrate the knowledge on landing gear well flows generated through their chosen approach (numerical, experimental, analytical or by acoustic analogy) with the output from fellow students who are tackling the same flow by a different technique. This re-focusing on the flow physics rather than on the investigative technique constitutes a key point of strength in this novel post-graduate research training. By working together, students can also develop an in-depth knowledge of alternative approaches, understanding their potential, limitations and their applicability to future research theme.

attendees at Toulouse meeting, september 2008The proposed research programme introduces inter-European mobility to early stage researchers right at the beginning of their career. This programme allows the constitution of an inter-European unsteady aerodynamics research group of young researchers who learn to work together. This is an innovative aspect with respect to conventional PhD training, where most early stage researchers feel encapsulated in a small circle of specialists at their institute, sometimes consisting of just their supervisor and themselves, without appreciating the existence of, nor benefiting from, the international community of specialists beyond this group. Through this innovative programme, trainees can put together their individual specific skills/research techniques to progress, as established researchers, to other European multi-national research teamwork-type programmes. The outcome of this programme is a Human Resource (HR) structure of early stage researchers for the European Research Area (ERA). It is expected that this structure is well-equipped to interact with other researchers, after the completion of the early stage training, to attack multi-disciplinary ERA challenges. The networking in this training has the potential to provide a durable bridge for the transfer of knowledge between EST researchers who choose to go in industry after their studies and those who choose an academic career. The Marie Curie Fellowship Association is instrumental in developing contacts in this direction and the trainees is encouraged to take advantage of the membership and activities of this Association
