Description
In the highly populated LEO region the controlled disposal of satellites, upper rocket bodies and interstages at the end of their life cycle requires effective propulsion systems. This presentation introduces the development of a novel Solid Propulsion System designed for deorbitation manoeuvres, utilizing an aluminium-free propellant Solid Rocket Motor (SRM) integrated with a dedicated Thrust Vector Control (TVC) system. This concept is a result of several consecutive ESA activities performed by Łukasiewicz Research Network – Institute of Aviation and its partners from Poland. The SRM is engineered to address the challenges of high ΔV and low acceleration manoeuvres, requiring extended burn times and advanced thermal insulation solutions. The TVC system ensures precise control during the deorbitation process. The presentation presents the design, development, and testing phases of the SRM Engineering Model, highlighting the innovative approaches taken to meet the stringent requirements of Space Debris Mitigation guidelines. Emphasis is placed on the scalability and modularity of the system, catering to various satellite sizes and mission profiles. Conclusions from the initial test campaign of the TVC system are also presented, together with the further development roadmap. The findings contribute to the advancement of sustainable space operations by offering a reliable solution for controlled satellite deorbitation, aligning with international Space Debris Mitigation standards and ESA’s Clean Space initiatives.
