Abstract
AE faculty at TU Delft is currently developing a PocketQube satellite under the name of Delfi-PQ. Following the previous study, performed on a high level systems engineering on Delfi-PQ propulsion sub-system, there is a need to verify the propulsion sub-system's design, its final operational envelope values, and propulsion sub-system's requirements by using TEST and ANALYSIS methods. Leak, volume and mass, solenoid valve PWM, and heater efficiency tests have been performed. The verification tests of the propulsion sub-system design provided a lot of valuable information. Not only some of the its requirements have been verified, but also the underlying issues have been observed, registered, and described for future researchers who are going to test such a micro-propulsion system and optimize its design.
