Testimony of Fabin Delcan

What is your background?

I first went to a state secondary school in Pau, Saint-John Perse, before entering the MPSI-MP preparatory school at Camille Jullian, a small preparatory school with only one MP and one PC. There weren’t many people admitted to the grandes Mines, but I had some excellent teachers and some very good friends!

Why did you choose ISAE-SUPAERO? What do you think are the school's strengths?

Like many of us, ISAE-SUPAERO was my goal even before I started preparatory school. As the son of an air traffic controller and private pilot, I was quickly immersed in the world of aviation. In my little prep school, I hung in there and gave everything I had to get into my dream school.

Like many people at ISAE-SUPAERO, I was also admitted to higher-ranked schools, but I made this choice for several reasons:

  • Apart from Polytechnique, almost all the grandes écoles are the same in the world of work. The key is to differentiate yourself.
  • I wanted to do mechanics and physics in particular, and I got what I wanted! I was particularly interested in aviation and space, and it’s the best school in France in this field.
  • I was president of the rocket club and a member of OSE, as well as rowing, baseball and poker.
  • The many academic opportunities, in France and abroad.
  • Going to the same school as Thomas Pesquet is quite something, isn’t it?

Can you tell us about your double degree with X-HEC? Why did you make this choice?

After just over a year at ISAE-Supaero, I decided to be more than an engineer. I chaired the Institute’s large rocket construction club (+120 people) and got a taste for project management and steering.

The double degree takes place over two years:

  • A first year at École Polytechnique in 3A, where you can choose any subject (PA for friends) and take an entrepreneurial certificate. You also do a 3A internship like the Xs, usually in a start-up.
  • Then you go on to the MSc X-HEC Entrepreneur, a very practical master’s programme, with little theory and lots of guidance to help you launch a business. The classes are made up of one third engineers, one third business profiles and one third from other backgrounds, which encourages the formation of multidisciplinary teams.

I wasn’t born an entrepreneur, but I want to work in a dynamic environment, without fixed positions or rigid hierarchies. This double degree is the best option for me: it allows me to quickly gain experience in technical and business management while taking on a fascinating challenge: designing, managing a growing team, finding a market and convincing investors!

What areas and subjects have you chosen for 3A? Why or why not?

As part of my double degree, I did my 3A at École Polytechnique. I chose the Mechanical PA, coupled with an entrepreneurial certificate. I wanted to acquire a solid grounding in mechanics so that I could design autonomous systems such as drones. Mechanics is a bit of a catch-all area in engineering. I already had some knowledge of software and automatic control, which I wanted to complement with a mastery of tools and methods in fluid and structural mechanics, to better understand the challenges of design and prototyping. As for the entrepreneur certificate, it was a natural choice to gain experience before my final year in entrepreneurship.

What are your career plans?

I’m not completely sure about my future yet, but what motivates me is the start-up environment, its dynamism and its challenges. I hope to be able to found or join a very technical start-up, probably in the field of drones. But it all depends on the people I meet next year: a start-up is above all a human adventure and a close-knit team!

A word about life in Toulouse and more particularly on campus?

Toulouse is great fun! Most of us stay on our super campus, including at weekends, which means we can organise lots of community projects and events.

I know that the community aspect is often overlooked when choosing a preparatory school, but on a day-to-day basis it has a real impact. Getting involved in an association means making new contacts and developing personally and professionally. At ISAE-SUPAERO, there are significantly more associations per student than on the Plateau de Saclay, with many technical and aeronautical associations run by real enthusiasts.

If you had any words for students taking the CCMP?

Whether this is a huge challenge for you or a formality, bear in mind that the questions are often very theoretical: Take the time to go into the subjects in depth!

Testimonials from Alex Dejoie and Sofia Cardola, engineering and master in aerospace engineering students

ISAE-SUPAERO recently welcomed some 40 companies from a wide range of industrial and service sectors to its campus. These companies, represented by alumni and HR managers, were able to share internship and job opportunities with over 500 students in attendance. The event also provided an opportunity for privileged exchanges between students and professionals on current and future challenges and projects. These close encounters were particularly enriching, providing young talent with sound advice and a mutual understanding of needs and expectations! The Enterprise Village is a fantastic opportunity to forge links and develop your professional network, while at the same time widening the field of possibilities. Through this initiative, ISAE-SUPAERO, at the heart of our students' training, has reaffirmed its central role in guiding them towards the professional world. Read the testimonials of Alex Dejoie, a student engineer specializing in astrophysics and space, and Sofia Cardola, a student in the Master in Aerospace Engineering program.
