Abstract
Reliable propellant tank pressurization in a launcher is a critical requirement for mission success, as deviations in propellant or tank pressure can compromise feed system operation or even lead to structural failure of the tanks.
This thesis addresses the development of a pressure regulation strategy for the pressurization systems of the fuel and oxidizer tanks in the first stage of Maiaspace’s mini-launcher. The work focuses particularly on the creation of pressurization system models capable of replicating system behaviour with sufficient accuracy for design studies, while prioritizing fast development and computational efficiency. Simulations of the developed models served as the basis for defining regulation strategies for the oxygen and methane tank pressurization systems.
