Abstract
Launch vehicles' reusability has been regaining a lot of interest in recent years. Therefore, to continue the development of these types of vehicles, it is important that they are as reliable as possible, even in the case of faults, to achieve their objective of consistent reusability.
Current literature does not offer a detailed analysis of the influence of different faults or an analysis of these allocation algorithms for reusable rockets in a crucial scenario of these rockets, such as the descent phase. Hence, this thesis focuses on the development and investigation of the advantages of a fault-tolerant control allocation solution for propulsion system faults, to be applied in the powered descent and landing phase of a clustered-engine reusable launch vehicle. Furthermore, the different types of faults and fault characteristics are analysed to understand their impact on a mission of this sort.
