Internship / Hypersonic (m/f)

Airbus Safran Launchers Les Mureaux

Created by Airbus Group and Safran, Airbus Safran Launchers is a 50/50 joint venture bringing together the expertise and assets of both groups in terms of civil and military space launchers.
Its industrial and technological heritage, linked to the passion which drives the men and women of Airbus Safran Launchers, is what has enabled it to become the current world leader in space access.
Through clever operations at all levels, Airbus Safran Launchers offers innovative and competitive solutions to its customers, in order to bring the European space industry to its highest level and thereby guarantee independent access to space.

Airbus Group is a global leader in aeronautics, space and related services. In 2015, the Group - comprising Airbus, Airbus Defence and Space and Airbus Helicopters - generated revenues of € 64.5 billion and employed a workforce of around 136,600.

Our people work with passion and determination to make the world a more connected, safer and smarter place. Taking pride in our work, we draw on each other's expertise and experience to achieve excellence. Our diversity and teamwork culture propel us to accomplish the extraordinary - on the ground, in the sky and in space.

Description of the job

Airbus Safran Launchers (Les Mureaux) is looking for an intern for a 6-month internship.

During their entry into the Earth's atmosphere, reentry vehicles (civil or military) go through a black-out phase and are subjected to heat flows that may require specific thermal protection. The black-out is due to flow ionisation and requires that chemical kinetics of various elements and their associated reactions are taken into account. In the case of high-speed reentry, the heat flow is not only due to the convection flow but also the radiation flow which may become predominant at a very high speeds. In digital simulations, the level of the radiation flow will depend on whether or not thermodynamic balance (a single temperature [ETL] or several temperatures [NETL]) is taken into account within the flow.

During atmospheric re-entry, the flow changes from a laminar regime to a turbulent regime. This has an impact on the level of the heat flows and requires using a turbulence model in digital simulations. The level of the heat flow will also depend on the catalytic nature (the combination of atoms at the wall) of the thermal protection material of which the vehicle's wall is made of. To carry out these predictions, we have two in situ Navier-Stockes (CFD) codes, which each have their own specific properties (catalytic, turbulence, chemical kinetics, ETL/NETL modelling,…).

This internship will start on 1st February 2017 (subject to some flexibility).

Profil recherché

Tasks & accountabilities

The aim of this internship is to acquire the experience of implementation of these two codes in case of high-speed reentry, and to perform cases of cross-validation calculation.
A previous internship allowed to compare the two CFD codes in ETL for EULER calculations on a simplified form.
The purpose of your internship is to study more specifically the NS calculations (catalycity, turbulence, ETL/NETL,..) for a capsule-type vehicle.

The internship will be composed of several steps:

·  Familiarisation with the code,
·  Validation of various models in terms of robustness and precision on simplified test cases,
·  Application to a capsule-type reentry vehicle and comparison with available data,
·  Synthesis of the effective capacity of the tested digital tools.

Required skills

You are in the final year of engineering school, completing a Master's degree or in the 5th year of university, specialising in Aerodynamic Engineering.

Ideally, you have initial work experience.

You are a good team player and have excellent interpersonal skills.

À propos de Airbus

Constructeur aéronautique, Airbus est aujourd’hui le leader mondial de la construction d’avions de ligne. Créé à la fin des années 1960 avec le projet A300, lancé à l’initiative de plusieurs pays européens, il fabrique des avions de 100 places (A318) à plus de 500 places (A380). Il appartient au groupe EADS, renommé « Airbus Group » en 2014, et présent sur 170 sites dans le monde. 6000 avions Airbus sont aujourd’hui en exploitation, avec une volonté du constructeur aéronautique de mettre l’accent sur la réduction de l’empreinte carbone (réduction de la quantité de CO2 produite par avion).

Airbus, dont le siège est situé près de Toulouse, compte 59 000 employés dans le monde et 15 sites principaux situés en France, Allemagne, Espagne et Royaume-Uni (ainsi que d’autres sites aux Etats-Unis, en Chine, au Moyen-Orient et au Japon).
