This thesis presents a preliminary study for the development of a High Test Peroxide (HTP) propellant tank suitable for CubeSat applications. The tank features a cuboidal shape, specifically chosen to make better use of the limited space available on CubeSat platforms, thereby allowing for an increased propellant volume.
Following a brief trend analysis of the current CubeSat market, the study explores the possibility of managing the propellant through a Propellant Management Device (PMD). This device enables the delivery of gas-free propellant in the low-gravity environment of the mission by exploiting surface tension forces. A PMD composed of a set of vanes and a radial sponge was analytically designed.
The key idea was to integrate these elements directly into the tank shell, thus obtaining a monolithic, reliable storage subsystem with no moving parts.
Additionally, considerations were made regarding the storability of hydrogen peroxide within the tank, and in the final part of the work, a topological optimization process was carried out to reduce the tank’s final mass.
