Generate a conceptual design of a water-based electric thruster
The first objective aims to create a conceptual design for a water-based electric thruster, focusing on evaluating Hall Effect Thrusters (HET) and Gridded Ion Thrusters (GIT) for their suitability with water as a propellant. This objective, covered in WP2 and WP4, seeks to explore various design adaptations necessary for these thruster types to efficiently use water, laying the groundwork for future development. In pursuit of this objective, the project will undertake a comprehensive examination of the challenges presented by water as a propellant in electric propulsion systems including evaluating the modifications required to adapt existing thrusters and/or neutralizers to effectively utilize water. Moreover, a feasibility study will be conducted to identify solutions
that could offer a better performance or increase the overall thruster efficiency. The exploration will cover a large spectrum of design considerations, from propellant ionization mechanisms to thruster geometry, ensuring a thorough understanding of the potential of water-based propulsion and ultimately posing the basis for future improved and optimized designs. Moreover, a focus shall be put on the assessment of the best neutralization strategies when employing water propellant. The target maturity level for these conceptual designs is TRL 2, signifying an early stage of development where concepts and applications are formulated but not yet tested.
