LIQUID Micro Pulsed Plasma Thruster Project

The L-uPPT project is committed to develop and assess the functionality of a novel PPT technology based on liquid propellant, expected to enable significant improvements over traditional solid Teflon-based PPTs in terms of propellant utilization and impulse bit predictability through a tight control of the mass of propellant injected. In order to assess L-µPPT functionality performance, a new thrust stand is necessary for measurement of impulse, because a number of microthrusters are repetitively operated in pulses and pulsed thrust is generated. The specific know-how of Mecartex on high precision mechatronics solutions, has been profitably used during the project to develop a dedicated thrust balance to carry out the measurement of the thrust in the vacuum chamber.
