The combined simulation of propulsion system performance and trajectory is crucial for the design of a space mission. Therefore the trajectory simulation and optimization software ASTOS is used together with the rocket propulsion simulation tool Ecosim- Pro/ESPSS to simulate and optimize different missions for launcher and spacecraft applications. A special focus is put on hybrid rocket engines. This class of rocket engines is advancing at a high speed and applications in different fields are investigated and developed. High safety, low cost and using ”green” propellants makes hybrid rocket engines a viable choice for a propulsion system. A simulation toolset for ASTOS to calculate and optimize hybrid rocket engine performance is developed. A connection to the dedicated propulsion simulation tool ESPSS is implemented to further improve the simulation of hybrid rocket engines in a loop with the trajectory design. The software interface is successfully implemented and first optimization results look very promising.
