项目摘要

This Collaborative research project will study the biomechanics of Monarch butterfly flight, with the goal of creating engineered flight vehicles with unprecedented capabilities. The seemingly fragile Monarch exhibits the longest flight range among insects. Individual Monarch butterflies may travel up to four thousand kilometers during the annual migration between North America and Central America. This project will examine the distinguishing characteristics of Monarch butterfly flight, including the slow tempo of the flapping wings, the effects of wing flexibility, and the mechanical coupling of wing and body movements. Furthermore, the Monarch flies at relatively high altitudes. Glider pilots have observed Monarch butterflies soaring on thermal currents at altitudes up to 1,250 km, and their overwintering grounds are at altitudes of up to 3,300 km. This project will examine whether the unmatched range of the Monarch among similarly sized animals lies in the combination of large, flexible wings, slow flapping speeds, and high-altitude flight. A multidisciplinary team will integrate expertise in computational mechanics, biological experiments, fluid dynamics, and nonlinear controls to uncover the physical mechanism underlying the highly efficient Monarch flight. This knowledge will be applied to the creation of transformative, bio-inspired micro-air vehicles with enhanced flight efficiency and superior flight range. Micro-air vehicles with extended flight range will improve the national quality of life by enabling long-term monitoring of environmental hazards. These vehicles will enhance national security by allowing long-term surveillance of large areas, and by providing long-range reconnoitering capacity for search and rescue. Engineering models of Monarch flight will also contribute to the understanding of their migration patterns, and thereby support the conservation of this endangered species.The primary scientific objective of this project is to test the hypothesis that high-altitude flight is a critical component to the long-range flight characteristics of the Monarch butterfly. This will be achieved with a series of experimental, computational, and theoretical research efforts. The flight maneuvers of live Monarch will be measured by a motion capture system in a low-pressure chamber simulating the ambient environment at various altitudes. The measurements will be validated with computational fluid dynamics simulations for the unsteady viscous flows around flexible flapping wings integrated with a multibody dynamics model representing the thorax and the abdomen deformation. The resulting aerodynamic model will be approximated by an artificial neural network for real-time dynamic simulation, from which a nonlinear feedback control system will be constructed via Floquet-Lypuanov theory. The fidelity of the computational dynamic model and the feedback control system will be verified against experiments with Monarch butterfly inspired micro-air vehicle and live butterfly flight measurements. These will provide a comprehensive analysis of the low-frequency flapping dynamics of an articulated, flexible multibody system representing the remarkable flight characteristics of Monarch butterflies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这项合作研究项目将研究帝王蝶飞行的生物力学,目标是创造具有前所未有能力的工程飞行器。看似脆弱的帝王蝶是昆虫中飞行距离最远的。在北美和中美洲之间的年度迁徙中,单个的帝王蝶可能会旅行4000公里。本项目将研究帝王蝶飞行的显著特征,包括拍打翅膀的缓慢克里思,翅膀灵活性的影响,以及翅膀和身体运动的机械耦合。此外,君主飞行在相对较高的高度。滑翔机飞行员曾观察到帝王蝶在1,250公里高空的热流中翱翔,它们的越冬地海拔高达3,300公里。该项目将研究君主在类似大小的动物中无与伦比的范围是否在于大型灵活的翅膀,缓慢的拍打速度和高空飞行的组合。一个多学科团队将整合计算力学、生物实验、流体动力学和非线性控制方面的专业知识,以揭示高效君主飞行背后的物理机制。这些知识将被应用于创造具有变革性的、生物启发的微型飞行器,这些飞行器具有更高的飞行效率和上级飞行范围。具有更大航程的微型飞行器将通过长期监测环境危害来改善国民的生活质量。这些车辆将通过对大片地区的长期监视和为搜索和救援提供远程侦察能力来加强国家安全。帝王蝶飞行的工程模型也将有助于了解它们的迁徙模式,从而支持对这一濒危物种的保护。该项目的主要科学目标是检验高空飞行是帝王蝶远程飞行特征的关键组成部分这一假设。这将通过一系列的实验、计算和理论研究来实现。在模拟不同高度周围环境的低压舱中,将通过动作捕捉系统测量实时Monarch的飞行机动。测量结果将与计算流体动力学模拟柔性扑翼周围的非定常粘性流与代表胸部和腹部变形的多体动力学模型集成进行验证。所得到的空气动力学模型将由用于实时动态仿真的人工神经网络近似,其中将通过Floquet-Lypuanov理论构造非线性反馈控制系统。计算动力学模型和反馈控制系统的保真度将通过帝王蝶启发的微型飞行器和活蝴蝶飞行测量的实验来验证。这将提供一个综合分析的低频扑翼动力学的铰接,灵活的多体系统,代表显着的飞行特性的帝王蝶。这个奖项反映了NSF的法定使命,并已被认为是值得支持的评估使用基金会的智力价值和更广泛的影响审查标准。
