摘要
对高超声速飞行器的单周期冲跃飞行轨迹进行了研究。建立了动力学模型和约束条件。仿真分析了升阻比、初始速度和初始弹道倾角对飞行轨迹性能的影响,并讨论了影响程度,确定了适于该飞行器的最佳飞行走廊,为后续的冲跃飞行轨迹完整设计和优化提供了参考。
The flying trajectory of single period skip for hypervelocity vehicle was studied in this paper. The dynamic model and constraint conditions were established. The effects and its amplitude of the lift to drag ratio, initial velocity and initial trajectory tilt angle on the performance of the flying trajectory were discussed through the simulation. The optimal flying passageway of some hypervelocity vehicle was valuable to the whole trajectory design and optimization in later.
