【摘要】 本文以临近空间高超声速滑翔飞行器为应用背景,对无动力滑翔制导方法进行了深入的研究和仿真分析。建立了以参考能量为自变量的飞行器动力学模型,形成了阻力加速度剖面自动生成、再入滑翔走廊设计、剩余航程预测等弹道规划算法,并进行了纵向和侧向制导律设计。最后以设计的高升阻比滑翔飞行器为对象,进行了仿真验证,仿真结果表明该滑翔制导方法具有较高的制导精度和适应性,满足临近空间高超声速飞行器滑翔段的制导要求。更多还原

【Abstract】 According to the application for unpowered hypersonic vehicle in near- space,a guidance method which is suitable to on- board trajectory generation is analyzed and simulated in detail.This paper established dynamic model which uses reference energy as independent variable first,and formed trajectory planning algorithmes including drag acceleration profile generation,reentry glide corridor design,remaining glide range pre- estimate etc.Then,the longitudinal and lateral guidance laws are designed.In order to make a simulation verification for the glide guidance method,a designed high L/D glide vehicle is used in this paper.Simulation results show that the guidance algorithm is effective and accurate,and satified kinds of constrains in guide flight.更多还原
