Solar Thermal Thruster
Design of a Solar Thermal Propulsion System with Thermal Energy Storage
With the number of spacecraft launches increasing each year, so does the search for more efficient and greener propulsion solutions. Electrical propulsion offers high specific impulses, but the provided thrust is lower than that of chemical propulsion. The novel concept of Solar Thermal Propulsion (STP) is a potential solution that offers a higher specific impulse than chemical propulsion and a larger thrust than electrical propulsion. The Green SWaP mission aims to make space exploration more sustainable and implements STP for the secondary propulsion system. This thesis presents the design of a 1.0 N STP system incorporating a Thermal Energy Storage (TES) to enable operation during eclipse periods. Several STP concepts are evaluated, and the selection is supported by thermofluidic analysis. A transient thermal model is developed to improve radiation loss estimations and minimise TES material mass. The resulting propulsion system achieves a predicted specific impulse of 870 s.

With the alignment of the planets in the 2030s, a perfect opportunity is presented to explore the outer reaches of the Solar System. With this, studying Uranus would become possible. With it being one of the least studied planets in the Solar System, the demand for accurate scientific data is high. This is where Ouranos comes in. This project has the specific purpose to design a scientific mission to Uranus, where measurements will be taken of its atmosphere. The summary below highlights the important parts and results of this report.
