Presentation of ONERA

ONERA, a central player in aeronautical and space research, employs more than 2,000 people. Placed under the supervision of the Ministry of the Armed Forces, it has a budget of 266 million euros (2022), more than half of which comes from study, research and test contracts. State expert, ONERA prepares the defense of tomorrow, responds to the aeronautical and space challenges of the future, and contributes to the competitiveness of the aerospace industry. He masters all the disciplines and technologies in the field. All the major civil and military aerospace programs in France and Europe carry part of ONERA’s DNA: Ariane, Airbus, Falcon, Rafale, missiles, helicopters, engines, radars, etc. Recognized internationally and often awarded, its researchers train many doctoral students.

Presentation of the department

The Multi-Physics for Energetics department carries out research and studies for the benefit of industrialists and state services in the aerospace field, both civil and military, but also in close connection with the academic world. The Department’s activities are divided into six strategic areas: Innovative energy systems; The performance of the propulsion systems; Experimentation under representative conditions; Multi-physics modeling and simulation; Safety and environmental impact; Multi-physics software platforms.


In the PRA (Aerobic Propulsion) research unit of the DMPE, which carries out studies and research on aerobic thrusters such as turbojets and ramjets, you are more specifically responsible for the development and implementation of a system-type software platform for the design and performance calculations of aerobic engines of the turbojet or combined turbostator type.

For the benefit of several studies in connection with the European Clean Aviation research program (ACAP, NACOR, etc.) and the DGAC recovery plan in aeronautics, your main functions consist of:

  • Contribute to the development or improvement of ONERA’s TURBEST software components (air inlet, compressor, turbine, combustion chamber, nozzle, etc.);
  • Set up the assembly of components for different motors both for sizing and for operation outside adaptation;
  • Contribute to more in-depth studies relating to critical operating phases, in particular transitions between modes;
  • Contribute to IT tasks related to platform configuration management;
  • Carry out applied studies for the design and calculation of motor performance in response to ad hoc requests from the DMPE or other ONERA departments;

You will also develop relationships with various state and national industrial partners in the aerospace field, as well as with research organizations or international partners. You are also in contact with the academic world through the supervision of end-of-study engineering or master’s trainees.

This position will be the subject of an open-ended contract Project or Research Operation Contract for the ACAP project for a foreseeable duration of 42 months.


  • Doctor-engineer in fluid mechanics or energy or Aeronautical engineer or generalist with energy or propulsion option.
  • Proven skills in Python, Fortran90C++ programming under Linux and Windows.
  • Knowledge and practice of calculation codes in aerothermochemistry appreciated (Gasturb, Ecosimpro, …)
  • Good command of English.


Joining ONERA means joining the leading player in aeronautics and space research in France, it means building the future now, it means innovating every day in a cutting-edge sector.

At ONERA, you will find a balance between professional life and personal life and an environment that promotes the continuous training of employees.

Our company is committed to a policy in favor of the integration and continued employment of people with disabilities.
