本研究的目的是将多学科优化方法应用于具有先进吸气式发动机的高超音速实验飞行器的概念设计。使用这种方法，我们获得了必要的车辆尺寸和最佳飞行轨迹。车辆具有升降式车身形状。首先，我们将分析方法集成到优化问题中，其解决方案产生车辆的最小总重量。结果表明，飞行器总长约为 12 m，总重约为 4-5 Mg。这些信息使我们能够确定高度可行的高超音速飞行器的最佳飞行器配置和飞行轨迹。此外，轨迹优化使飞行器能够在不消耗推进剂的情况下滑回起飞点。这项研究证实了所提出的分析和优化方法的有效性。
The purpose of this study is to apply a multidisciplinary optimization method for the conceptual designs of hypersonic experimental vehicles with advanced airbreathing engines. Using this method, we obtain the necessary vehicle sizes and optimal flight trajectories. The vehicle has a lifting body shape. First, we integrate analytical methods into the optimization problem, the solution of which yields the smallest gross weight of the vehicle. The results indicate a vehicle that is about 12 m in total length and 4-5 Mg in gross weight This information allows us to determine the optimal vehicle configuration and flight trajectory for a highly feasible hypersonic vehicle. In addition, the trajectory optimizations enable the vehicle to glide back to a takeoff point without consuming propellant. This study confirms the effectiveness of the proposed analysis and optimization method.
