PSO based Ascent Trajectory Optimization for Air-breathing Hypersonic Vehicle

In actual engineering cases, the air-breathing hypersonic vehicles are usually propelled by rockets at the ascent stage. Considering the narrow flight corridor of the vehicles and the scramjet ignition requirement, a steady and precise state transition between the two stages is crucial. In this paper, we combine the conventional project trajectory design idea with an improved particle swarm optimization algorithm to find a feasible solution under the actual constraints. A case study is presented to illustrate the effectiveness of the proposed methodology, which is of valuable reference for further research.
