Postdoctoral research program: the candidate will start with a bibliography of existing analytical approaches and models found in the literature concerning the understanding of the operation of the vacuum arc thruster. He will propose simple models to understand the presence of multiply charged ions and their influence on the thrust.
The “new space” market aims at developing new business models relying on new applications (telecommunication, Earth observation....). In order to develop this business model, the in-space infrastructure must be cheaper to make quicker profit. Electrical Propulsion is a strategic item for Europe and must be improved from technical and economical points of view, to ensure European leadership. The development of an innovative satellite propulsion concept, by changing the physical principle currently used in thrusters, is a key to reduce propulsion costs.
The magnetic enhanced vacuum arc technology can challenge the classic Hall Thrusters (HT) and Gridded Ion Engines (GIE). This disruptive physics allows a high level of performance while offering the major advantage to store propellant as solid metal. Due to this characteristic, our propulsion module is simpler and smaller. For small satellite platforms, size is a key point for the adoption of this technology. Therefore, the PJP project is based both on the use of a vacuum arc plasma thruster and on the use of innovative systems to trigger and feed it. These innovations allow an increased “effective” fuel capacity of the satellites by eroding a larger quantity of the solid metal propellant contained in the propulsion module, in order to provide the thrust duration deemed necessary for operations.
Strong knowledge in vacuum arc
The LAPLACE laboratory is a mixed research unit belonging to three supervisory establishments (CNRS, Paul Sabatier University and Institut National Polytechnique de Toulouse) and has 160 permanent staff and more than 150 doctoral and post-doctoral students. It is located on two sites, the Rangueil campus and the ENSEEIHT.
The research carried out at LAPLACE is in the field of electrical energy and plasmas and covers a continuum of activities which includes the production, transport, management, conversion and use of electricity. The fields of application of research concern transport, aeronautics and space, environment and energy, biology and health.
