This study is focused on the development of a prototype of a modular 1U propulsion system based on a water resistojet that can be installed on board CubeSats from 3U. During the study and development, various technical choices have been investigated: working fluids, geometries for the heat exchanger, the final temperature of the hot gases, operating pressures, layouts and architectures for the complete propulsion module. The testing of the prototypes has been carried out inside a vacuum chamber and have provided important information for the validation of the engine designs and for the development of a complete final prototype of the engine module. COTS components have been extensively used, by also considering the use of advanced technologies such as 3D printing, nowadays increasingly useful in aerospace applications. The following paper will describe the process of design, construction and testing of the resistojet prototypes made with the S5Lab research laboratory at the Sapienza University of Rome.

Abstract
This study is focused on the development of a prototype of a modular 1U propulsion system based on a water resistojet that can be installed on board CubeSats from 3U. During the study and development, various technical choices have been investigated: working fluids, geometries for the heat exchanger, the final temperature of the hot gases, operating pressures, layouts and architectures for the complete propulsion module. The testing of the prototypes has been carried out inside a vacuum chamber and have provided important information for the validation of the engine designs and for the development of a complete final prototype of the engine module. COTS components have been extensively used, by also considering the use of advanced technologies such as 3D printing, nowadays increasingly useful in aerospace applications. The following paper will describe the process of design, construction and testing of the resistojet prototypes made with the S5Lab research laboratory at the Sapienza University of Rome.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
