Abstract

Drones operating in an urban environment pose a potential collision threat to rotorcraft. In this paper, the battery pack of the DJI MAVIC 2 ZOOM is analyzed since the battery is considered to be the greatest threat due to its high weight and stiffness. Following a pyramid-type building block approach, a high-fidelity model simulation was developed for LS-DYNA based on a wide range of experiments, ranging from quasi-static material tests to quasi-static component tests up to high-velocity impact experiments. The high-fidelity model allows the prediction of damage in potential collision scenarios between a high-speed rotorcraft and the battery pack of the drone. For the particular impact configuration analyzed within this paper, the drone battery does not cause catastrophic failure of the windshield of the rotorcraft.

无人机和旋翼飞行器之间的碰撞:电池组碰撞响应的建模

在城市环境中操作的无人机对旋翼飞机构成潜在的碰撞威胁。在本文中，大疆MAVIC 2 ZOOM的电池组进行了分析，因为电池被认为是最大的威胁，由于其高重量和刚度。采用金字塔型构建块方法，基于广泛的实验，从准静态材料测试到准静态组件测试，再到高速冲击实验，为LS-DYNA开发了高保真模型仿真。高保真模型允许在高速旋翼机和无人机电池组之间的潜在碰撞场景中预测损坏。对于本文分析的特殊冲击构型，无人机电池不会造成旋翼机挡风玻璃的灾难性失效。

期刊介绍： The Journal of the American Helicopter Society is a peer-reviewed technical journal published quarterly (January, April, July and October) by AHS — The Vertical Flight Society. It is the world''s only scientific journal dedicated to vertical flight technology and is available in print and online. The Journal publishes original technical papers dealing with theory and practice of vertical flight. The Journal seeks to foster the exchange of significant new ideas and information about helicopters and V/STOL aircraft. The scope of the Journal covers the full range of research, analysis, design, manufacturing, test, operations, and support. A constantly growing list of specialty areas is included within that scope. These range from the classical specialties like aerodynamic, dynamics and structures to more recent priorities such as acoustics, materials and signature reduction and to operational issues such as design criteria, safety and reliability.
