摘 要: | 高速面对称飞行器大空域、宽速域和大攻角变化范围的飞行特点,导致失稳模式多、稳定性差、通道耦合严重、姿控难度大等系列问题,为飞行器的总体设计带来了很大挑战.文章针对高速面对称飞行器抗失控设计难题,基于耦合稳定性与可控特性理论研究,综合考虑总体多专业设计约束,发展了飞行器总体抗失控设计方法.通过该方法,可以获得多专业参数对总体性能与稳定特性的影响规律,进而对飞行器的总体性能、稳定性与可控性进行综合优化设计.

Abstract: | The plane-symmetric configuration has been widely used for new flight vehicles to achieve a wide-velocity-range and large-space flight. However, large flight amplitude and speed arrange result in poor stability and uncontrollable flight. In this paper, the lateral-directional coupling was comprehensively considered in the flight vehicle design, and a multidisciplinary designing method was presented. By the aid of this designing method, a quantitative study of the design parameters for the stability and performance parameters can be conducted, which can further support optimization of the overall design. |
