MP2S · MODULAR PULSED PROPULSION SYSTEM

MP2S is an innovative project, aiming at filling the gap on the 200W class propulsion modules, this power segment being largely popularized by the new space market actors. The main goal of the project is to mature and develop up to TRL5 a Pulsed MPD Arc Discharge Chamber as a building block for an electrical pulse propulsion modular concept. The Consortium is composed of high level specialists, representing Industry: COMAT, ENDUROSAT and Plasma Solve and Research and Technology Organizations: CNRS (two Laboratories: ICARE and LAPLACE), University of Stuttgart. They have a broad experience and know-how in the area of electric propulsion, Plasma physics, simulation, tests, mass manufacturing and business model for space. CNRS and University of Stuttgart will perform experiments and modelisation for a better understanding of physical phenomena of pulsed propulsion. That will allow to characterize different propellant choices, current discharge wave form and magnetic topology. The Consortium will also perform studies to optimize the cathode erosion in pulsed mode, allowing to design new electrodes for a significantly increased thruster total impulsion. Then, PlasmaSolve will customize a software able to simulate different configuration of the P-MPD thruster. Design iterations will be performed to reach the required level of performance. Based on those results, the integrated Pulse MPD building block (with integrated fluid management system) will be developed and validated, with outstanding performances. The modularity and versatility of the propulsion module will bring value to the satellite and enable new in-orbit mission design by Endurosat(ie docking). The industrial strategy will ensure competitive cost, mass production capacity and easy assembly, thanks to additive manufacturing technology and plug and thrust concept. The MP2S partners will disseminate this disruptive and modular solution within the new space market while supporting the European space strategy.
