摘要

由于这种无人驾驶飞行器(UAV)的计划机身可承载 25 公斤的有效载荷,因此了解其结构能力(如在不同情况下的抗压和抗拉强度)至关重要。为了理解机身的流固相互作用(FSI),本研究设计并分析了用于复杂陀螺仪无人机机身的轻质材料。还建立了一个陀螺仪无人机复合材料机身的计算机模型,以检验其耐用性。飞机业务中的一个重要因素是最大限度地减少不必要的重量,FSI 的这项研究强调了三明治及其混合组合在这方面的重要性。材料确定后,使用先进的计算复合材料平台对大约 140 种材料组合进行了测试,其中使用了四种不同的轻质材料系列。流体载荷(压力)被导入 ANSYS workbench 17.2,然后根据应用领域的边界条件对结构机身进行求解。此外,还使用高速喷气设施进行了实验,以验证计算的改进。陀螺仪无人机的机身材料已缩小到最后的竞争者名单。由于工作重点是 FSI 分析,因此这里讨论的计算流体动力学 (CFD) 结果不多。只有将 CFD 分析得出的输入压力施加到 Gyrodyne 无人机上,才能进行 FSI 分析。

Multi-perspective structural integrity-based computational investigations on airframe of Gyrodyne-configured multi-rotor UAV through coupled CFD and FEA approaches for various lightweight sandwich composites and alloys
As this unmanned aerial vehicle (UAV) has a planned airframe that can carry a 25 kg payload, understanding its structural capabilities, such as its compressive and tensile strengths under different situations, is essential. For the purpose of comprehending the fluid–structure interaction (FSI) of the fuselage, this study designs and analyses the lightweight materials used in the airframe of a complex Gyrodyne UAV. A computer model of a composite airframe for a Gyrodyne UAV is built to examine its durability. An essential factor in the aircraft business is minimizing unnecessary weight, and this FSI study emphasizes the importance of sandwiches and their hybrid combinations in this regard. After the material finalization, around 140 material combinations are tested using an advanced computational composite platform, in which four different lightweight material families are implemented. The fluid load (pressure) is imported into ANSYS workbench 17.2, and the structural airframe is then solved according to the boundary conditions of the application domain. Also, experimental experiments using the high-speed jet facility are run to verify computational improvements. Materials for the airframe of the Gyrodyne UAV have been narrowed down to a final list of contenders. As the work focuses on the FSI analysis, not much computational fluid dynamics (CFD) results were discussed here. Only the imported pressure from the CFD analysis was imposed on to the Gyrodyne UAV to proceed for the FSI analysis.
