摘要：
现代高性能战斗机通过推力矢量技术突破了常规飞行包线的机动性限制，从而实现超机动性。随着仿生无人机（UAV）的不断发展，通过仿生机制实现超机动性的潜力逐渐显现。迄今为止，这一潜力尚未得到充分研究：尚未证明仿生无人机具备推力矢量飞机所拥有的任何经典超机动性形式。本文通过展示仿生变体翼无人机如何以较低的变体复杂度执行复杂的多轴机头指向与射击（NPAS）机动，证明了这一能力。研究采用非线性飞行动力学分析，对由仿生变体产生的飞行器配平状态多维空间的范围与稳定性进行表征。在仿真中，对该配平空间的导航为生成开环NPAS机动提供了一种有效的基于模型的制导策略。我们的结果证明了仿生飞行器具备与空战相关的超机动能力，并为此类飞行器中更多经典与非经典超机动形式的探索、表征与制导提供了策略。
英文摘要：
Modern high-performance combat aircraft exceed conventional flight-envelope limits on maneuverability through the use of thrust vectoring, and so achieve supermaneuverability. With ongoing development of biomimetic unmanned aerial vehicles (UAVs), the potential for supermaneuverability through biomimetic mechanisms becomes apparent. So far, this potential has not been well studied: biomimetic UAVs have not yet been shown to be capable of any of the forms of classical supermaneuverability available to thrust-vectored aircraft. Here we show this capability, by demonstrating how biomimetic morphing-wing UAVs can perform sophisticated multiaxis nose-pointing-and-shooting (NPAS) maneuvers at low morphing complexity. Nonlinear flight-dynamic analysis is used to characterize the extent and stability of the multidimensional space of aircraft trim states that arises from biomimetic morphing. Navigating this trim space provides an effective model-based guidance strategy for generating open-loop NPAS maneuvers in simulation. Our results demonstrate the capability of biomimetic aircraft for air combat-relevant supermaneuverability, and provide strategies for the exploration, characterization, and guidance of further forms of classical and non-classical supermaneuverability in such aircraft.
