MATI

Main Goals of the Project

The MATI project is a strategic research initiative funded by the Italian Ministry of University and Research (MUR) under the National Aerospace Research Program (PRO.R.A.), specifically within the "Innovative Propulsion" framework. The primary mission of the MATI project is to advance the Technological Readiness Level (TRL) of disruptive electric propulsion systems, aiming to bridge the gap between theoretical concepts and flight-ready hardware. The project focuses on three breakthrough propulsion architectures designed to enable the next generation of space missions. First, it addresses Magneto Plasma Dynamic (MPD) thrusters, which are high-power systems essential for deep-space exploration and interplanetary missions, such as those to Mars. Research in this area focuses on solving critical issues like electrode erosion and plasma instabilities. Second, the project places a strong emphasis on Air-Breathing Electric Propulsion (ABEP). This technology is a game-changer for satellites in Very Low Earth Orbit (VLEO) because it collects and processes residual atmospheric gases to use as propellant, theoretically allowing for infinite mission lifetimes. Finally, the project targets the maturation of Helicon Plasma Thrusters (HPT), which offer a reliable and versatile solution for orbital maneuvering thanks to their electrode-less design and high ionization efficiency.

CIRA Activities in the Project

CIRA plays a leading role in the project by integrating advanced numerical modeling, hardware design, and the expansion of experimental testing capabilities. A significant portion of CIRA’s effort is dedicated to developing proprietary design tools, as evidenced by the preliminary design of a 150W Argon Gridded Ion Thruster (GIT). This work involved validating a dedicated numerical tool that combines analytical formulas with Finite Element Method Magnetics (FEMM) to optimize the thruster’s performance using one of the VLEO atmosphere species as a propellant. Beyond the ABEP line, CIRA has completed the preliminary design of a 4.5 kW MPD thruster and a Helicon thruster (CHUBO1000), in collaboration with the University of Bologna, and that is currently ready for manufacturing. To support these developments, CIRA is upgrading its existing vacuum facilities (MSVC and SSVC) and spearheading the design of the LSVC (Large Scale Vacuum Chamber). This new large-scale simulator will be crucial for testing high-power thrusters exceeding 25 kW and for simulating the specific environmental conditions required for air-breathing propulsion testing.
