Typical motion analysis and model design of hypersonic glide vehicle

为了得到合理可行的高超声速滑翔飞行器运动轨迹和目标跟踪预测仿真数据,对滑翔飞行器典型运动进行了分析和模型设计.首先建立简化的飞行器动力学模型,分析了无横向机动的平衡滑翔和恒攻角跳跃滑翔两种纵向运动特点;然后在给定纵向运动条件下对摆动式和转弯式两种横向运动进行了分析,建立了不同横向运动与所需控制量攻角、倾侧角之间的关系模型;最后对设计的轨迹模型进行了仿真.仿真结果表明所设计的轨迹模型是合理的.

In order to obtain the reasonable and feasible trajectories of hypersonic glide vehicle and target tracking and prediction simulation data, this paper analyzes the typical motions of gliding vehicle, and designs its model. Firstly, the paper establishes a simplified vehicle dynamics model, analyzing the characteristics of two types of longitudinal motion, i.e. equilibrium glide without lateral maneuver and skip glide with constant angle of attack. And then, the paper makes an analysis on two kinds of transverse motion like swing and swerve under the given longitudinal motion condition, and establishes the relationship model between different lateral motion and the required control angle of attack and angle of inclination. Finally, the trajectory model is simulated. The simulation results show that the designed trajectory model is reasonable.
