| 摘 要： | 为了掌握高超音速飞机复杂的动态特性,提出了一种研究高超音速飞机模型的新方法.该方法采用MATLAB插值函数和S函数分别估算和建立高超音速飞机的气动参数及其六自由度的微分方程组,并在不同高度和速度下计算飞行的平衡点,然后通过比较平衡条件与约束条件,近似得到了整个飞行过程的飞行包线.仿真研究表明,该方法适合用在高超音速飞机模型上,仿真结果与期望要求相符合.

| Abstract: | In order to grasp the hypersonic vehicle models complex dynamic characteristics, a new hypersonic vehicle model method was proposed. This method applies interpolation functions and S functions in MATLAB to calculate the aerodynamic coefficients and establish six freedom differential equations, and computes the flight trim points in the different flight veloci- ties and altitudes, then approximately gets fight envelope of the whole flight process. The simulation studies show this re- search method adapts to the hypersonic vehicle models, and the simulation results are consistent with the desired demands. |
