Internship Aerodynamic modelling of rotors

Job description

We’re currently looking for an Intern on aerodynamic modelling of rotors to join our team!

Ampyx Power is developing an Airborne Wind Energy System (AWES), which aims at harvesting wind power through the use of automated airborne devices tethered to the ground. Our involvement in this technological field for the past 10 years places us at the forefront of its development. We are currently operating our fully-automated small-scale AP-2 to tune control strategies and validate our models, we are designing and assembling AP-3, which will demonstrate scaling and robust continuous automatic operations and we are also focusing on the conceptual design phase of AP-4, our first commercial prototype.

In this latter context, we are looking for an intern to develop an aerodynamic model of rotors. This model should be suited for both propellers and on-board generators, in order to support the conceptual studies of AP-4. Those devices are used respectively to generate thrust for climbing phases or to generate the power required for on-board avionics, at the penalty of an extra drag contribution.

Introducing our team and culture

We believe that a diversity of perspectives, ideas, cultures, and common passion to make a difference is needed to develop our pioneering technology.

Today we have a team of over 50 highly skilled professionals with more than 20 nationalities working from The Hague and Melbourne. We will be opening another office in Ireland in the near future. Most of our employees have a university degree and several employees have PhD background.

We have a socially open atmosphere in our company, placing value on trust. We think in terms of solutions rather than problems. We challenge each other and act decisively in our day-to-day work. Everyone's input is valuable and we work with clear deadlines and objectives. This way of working has helped us to make significant steps in our airborne technology development over the past 10 years.

What are you going to do?

This vacancy is within our Aircraft Design team, a group of 5 experienced aircraft design and structural engineers.

As a member of the Aircraft Design team, you will be working on the following project:

  1. You will first understand the key governing parameters and variables of rotor performance and initially approach the propulsive and re-generating efficiency with simple disk actuator theory in order to outline early results.
  2. Then, Blade Element Momentum Theory (BEMT) should be approached via existing open-source solutions that can permit to handle both windmill and propeller configurations so as to have a unified tool.
  3. After that you would perform sensitivity studies to investigate how re-generative and propulsive efficiency vary with the advance ratio, as a function of design variables such as twist law and airfoil section. For a given rotor, the intern would outline what compromise can be eventually reached between re-generative and propulsive efficiency, and how those are sensible to each other.
  4. Eventually, optimization routine would be approached by accounting for generic motor/generator efficiency curves in order to derive optimal rotor/generator designs.


What do we need from you to complement the team?

You are enrolled in engineering studies at Masters level (or equivalent), preferably within an aeronautical engineering department. Ideally you:

  • Are a team player;
  • Are proactive and you take ownership;
  • Like to learn new skills;
  • Report in a precise and concise manner;
  • Good at writing technical documentation.
  • As you will be part of an international team, you are proficient in English (speaking and writing).

We’d also like you to have extensive knowledge of:

  • Strong Analytical skills
  • Aeronautical definitions and concepts

Not a must-have, but we’d very much welcome the following experiences:

  • Matlab/Octave skills
  • Previous experience with BEMT or rotor aerodynamics

What do we have to offer?

We offer you an opportunity to contribute to a sustainable energy future. You will be working on a unique innovation using state-of-the-art technologies in an international team of enthusiastic professionals. Together, we will be launching our Airborne Wind Energy technology on the market in the next few years.

You can look forward to:

  • An internship fee based on your level of education
  • A personalized work-life balance;
  • Flexible working hours;
  • 30 leave days every year;
  • Excellent opportunities to take initiative and responsibility;
  • Working together with a team of professionals of top international status;
  • A daily freshly-made free lunch.

Where can you find us?

Ampyx Power is located in The Netherlands in the center of The Hague, a ten-minute walk from the Den Haag Hollands Spoor railway station. Our office in The Hague is also easily accessible for candidates from, for example, Utrecht, Amsterdam, Delft, Zoetermeer, Leiden, Rotterdam, Dordrecht and Haarlem. If you have questions about the company or processes, please send an email to If you have more specific, technical questions, please contact Vincent Bonnin on the following number: 0031 70 4020168
