| 摘 要： | 首先介绍了高速飞行器设计所面临的静稳定裕度、航向操纵性、三通道耦合、安全边界等问题，进一步梳理了高速飞行器的失控成因，包括飞行环境、飞行姿态、控制耦合、惯性耦合、动力学耦合等因素，在此基础上，回顾了一系列适用于飞行器设计的典型抗失控判据，如横航向稳定性参数、动态航向稳定性参数、横/航向操纵偏离参数、Weissman组合判据、横向稳定性特征参数等.这些参数或判据不仅可以在设计初期预测气动布局的好坏及其对操稳特性的影响，帮助工程师改进气动布局以使飞行器获得最佳的性能，还可用来预测飞行器在当前气动布局下所需要的控制资源以帮助飞行器合理应对耦合的影响，最后在设计完成后还可用这些判据分析飞行器飞行过程中的稳定性以及控制策略的合理性.

| Abstract: | The confusion faced by the high speed aircraft design, such as static stability, directional control, three channel coupling and safety limits, was introduced at the beginning of the paper. On the basis of combing the causes of high speed aircraft out of control, a series of operation and stability criteria suitable for aircraft design have been summarized in the paper. These criteria include lateral/directional aerodynamic static stability, dynamic directional stability parameter, lateral control (or aileron alone) departure parameter, Weissman criterion plane, lateral-directional stability dominant parameter and so on. Such criteria can not only predict the quality of aerodynamic layout and its influence on operation and stability characteristics in the early stage of aircraft design, but also can help engineers to improve the aerodynamic layout to get better performance of aircrafts. The control resources related to aircraft layout can be forecasted by the criteria, which help the aircraft cope with the influence of coupling reasonably. Finally, these criteria can be used to analyze the stability in the flight process and the rationality of the control strategy after the design. |
