论文摘要
通过使用推力矢量，现代的高性能战斗飞机超过了传统的飞行式启用限制对可操作性的限制，从而实现了超弱势性。随着仿生无人驾驶汽车（UAV）的持续发展，通过仿生机制具有超强性的潜力变得显而易见。到目前为止，尚未对这种潜力进行很好的研究：尚未证明仿生的无人机能够具有可用于推力向量飞机的任何古典超弱点。在这里，我们通过演示如何在低变形复杂性下进行复杂的多肢体鼻子点和射击（NPAS）操纵来展示这种能力。非线性飞行动力分析用于表征飞机装饰的多维空间的程度和稳定性，这些空间由仿生形变引起。导航此修剪空间提供了一种有效的基于模型的指导策略，用于在模拟中生成开环NPA操作。我们的结果证明了仿生飞机在与空中战斗相关的超贫困性上的能力，并为在此类飞机中的探索，表征和指导提供了进一步形式的经典和非经典超弱势性的策略。
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.
