System modelling tools allow analysis of the propellant chemical and fluid dynamic behaviour through the complete propulsion system, from the tanks through the connecting pipes, valves, manifolds, combustion elements and nozzles. These tools support the design and verification of rocket propulsion systems and troubleshoot anomalies during the utilisation phase.The appearance of new propulsion concepts necessitates extensions of these numerical tools.

Assembly, Integration, and Testing (AIT) processes occur during the phases C and D of the engineering processes of a given flight vehicle. System integration processes take place at the level of engineering models, structural and thermal models, and qualification models of flight vehicles.The current ATD tools cover the phases 0, A, and part of the phase B (B1) for design, and development of flight vehicles. Beyond those phases, the current toolset is not able to cover tasks of system integration and testing (phases C, D).

Achievements and status:
•Review of the State of Art of probes for Plasma Thrusters.
•Definition of probes requirements.
•Design and fabrication of several RFCLP, a couple of FC and an RPA.
•Integration and assembly of the probes at UC3M premises using different UC3M-SENER owned HPTs prototypes.
•Validation (by test) of the probes: RFCLP and FC pairs comparison, and RPA-LIF validation.
•Post-processing tool for results processing and interpretation.
