飞翼布局飞行器研究现状分析

Analysis of the current research on the flying-wing aircraft

对飞翼布局飞行器的发展脉络进行了梳理,涵盖了从其早期的进化史到现阶段的研究进展,并对未来的发展方向进行了思考和展望。同时,论述了飞翼布局飞行器的几个主要控制难点,具体包括:宽速域非线性状态下的姿态控制问题、多效应耦合下的高精度自主起降控制问题、气动模型近似及强扰动状态下的鲁棒控制难题,以及因多舵面冗余而引起的控制分配问题。此外,还深入讨论了当前重点研究的飞翼布局飞行器的流动控制问题,并对接下来主动流动控制技术的研究动向进行了阐述。

The development trajectory of the flying-wing aircraft was sorted out,encompassing the early evolutionary history to the current state of research,along with contemplation and forecasts regarding future directions.Meanwhile,several key control challenges associated with flying-wing aircraft were discussed,including attitude control in a wide-speed domain under nonlinear conditions,high-precision autonomous take off and landing control under multiple effect coupling,robust control issues with approximate aerodynamic models and under strong disturbances,as well as control allocation problems arising from multi-surface redundancy.Moreover,the discussion on flow control issues that were currently a focal point in flying-wing aircraft research were discussed in depth.The following research trend of active flow control technology was expounded.
