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.

通过耦合 CFD 和 FEA 方法对各种轻质夹层复合材料和合金的旋翼配置多旋翼无人机机身进行多视角结构完整性计算研究

由于这款无人机 (UAV) 的机身设计可承载 25 公斤的有效载荷，因此了解其结构能力（例如不同情况下的抗压强度和抗拉强度）至关重要。为了理解机身的流固耦合 (FSI)，本研究设计并分析了复杂 Gyrodyne 无人机机身中使用的轻质材料。建立了 Gyrodyne 无人机复合机身的计算机模型来检查其耐用性。飞机行业的一个重要因素是最大限度地减少不必要的重量，这项 FSI 研究强调了三明治及其混合组合在这方面的重要性。材料最终确定后，使用先进的计算复合平台测试了约 140 种材料组合，其中实施了四种不同的轻质材料系列。将流体载荷（压力）导入ANSYS Workbench 17.2中，然后根据应用域的边界条件对结构机身进行求解。此外，还进行了使用高速喷射设施的实验来验证计算改进。Gyrodyne 无人机机身的材料已经缩小到最终的竞争者名单。由于工作重点是 FSI 分析，因此这里没有讨论太多计算流体动力学 (CFD) 结果。仅对 Gyrodyne 无人机施加来自 CFD 分析的输入压力，以进行 FSI 分析。
