摘要
The flight performance of dual-mode scramjet engine vehicles is significantly influenced by their flight trajectory, as combustion efficiency and aerodynamic forces vary greatly with altitude. Numerous studies have focused on optimizing trajectories; however, these studies often overlook potential operational failures in the propulsion system, such as unstart and blowout. In this study, we introduce a trajectory optimization approach for dual-mode scramjet engine vehicles that aims to avoid these operational failures. This is achieved by developing a comprehensive combustion analysis model and proposing a failure mode discriminator using a Gaussian process classifier. We have developed a two-step trajectory optimization method utilizing Sequential Convex Programming. Ascent and cruising trajectories were optimized under both time-minimizing and fuel-minimizing objectives. The results indicate a preference for lower altitudes to increase air intake during the early stages of flight.
