Our team and mission

This position is based at the European Space Research and Technology Centre (ESTEC) - Noordwijk, Netherlands

Under the direct authority of the Mechanical Department, the Propulsion and Aerothermodynamics Division is responsible for the technical and strategic management of all areas related to chemical, electric and advanced propulsion, and aerothermodynamics analysis and verification.

In particular the division is in charge of:

• Support to projects and definition/execution of technology programmes in the areas of chemical propulsion (systems utilising liquid, solid, hybrid and gaseous propellants for spacecraft and launch vehicles), electric propulsion (electrostatic, electromagnetic, and electrothermal systems), advanced new propulsion systems (e.g. air breathing engines for advanced launch vehicles and applications of nuclear propulsion to space missions), external and internal aerothermodynamics of relevance to propulsion systems, ascent, cruise and re-entry of space vehicles through the Earth's or planetary atmospheres;
• Architecture and technology assessment of new space transportation vehicles for Earth orbit, exploration and orbital systems application;
• Development of components for propulsion systems (valves, regulators, tanks, GSE, etc.);
• Development of propulsion and aerothermodynamics simulation tools and support to the evolution of the related European test facilities.

Field(s) of activity for the internship

Topic: Thruster plume interaction, impingement and/or contamination

In preparation for upcoming lander missions (Argonaut, ExoMars Rosalind Franklin Mission), there is the need for improved understanding and modelling of plume-surface interaction, particularly to assess potential impacts on the spacecraft of regolith/dust particles and rocks ejected from the impinged soil. Depending on the plume and soil properties, large craters can form underneath the landing spacecraft which could alter the plume-surface interaction and the resulting liberated particle trajectories and impacts.

The internship will look at defining a parametric model of a landing spacecraft, including parametrised crater shapes, to enable semi-automatic creation of computational fluid dynamic (CFD) simulation set-ups. A large sensitivity study will then be performed using these CFD simulations to assess particle impacts and contamination potential under various landing conditions.
