The advantages of Topology Optimization (TO) are realized to a large extent due to the manufacturing freedom that Additive Manufacturing (AM) offer, compared to more conventional manufacturing methods. AM has the advantage of manufacturing shallow and complex structures previously not possible, and consequently opens up a whole new design spectrum. This thesis investigates the possibilities of using Topology Optimization as a tool to find stronger and lighter designs for the inlet turbine manifold in the rocket engine demonstrator Prometheus. The manifold is optimized by giving it more mass, subjecting it to load cases and pushing the topology optimization to make the manifold meet the weight requirement without exceeding the yield strength. Result validation indicates that the pressure and thermal loadings are the most prominent. The current topology optimization tools in ANSYS do not support optimization due to thermal features and thus optimization in the presented work has only been able to consider static structural loads. Nevertheless, it is possible to optimize the manifold due to static structural loads and achieve a manifold which satisfies the weight requirement. However, optimization tools due to thermal loading would be a desirable feature in the future.
