Hypersonic air-breathing vehicles, which implement ramjet and scramjet propulsion systems, demonstrate greater specific thrust in comparison to rocket engines. Additionally, these vehicles do not require oxidizers and are thus poised to be the future of hypersonic transportation. The trajectory of hypersonic aircraft plays a crucial function in enhancing flight efficiency because of the inherent connection between combustion efficiency and aerodynamic performance. Therefore, multiple studies have aimed to optimize the trajectory of hypersonic vehicles. Unfortunately, previous studies have not successfully addressed the possibility of disastrous operational breakdowns in the propulsion system, including unstart. In this research, we suggest a trajectory optimization method for hypersonic aircraft that presents a solution for preventing operational failure. To this end, a comprehensive combustion analysis model was developed and combined with the sequential convex programming to obtain optimal trajectory.
