Abstract

Fixed-wing unmanned aerial vehicles (UAVs) offer the best aerodynamic efficiency required for long-distance or high-endurance applications, albeit their runway requirement for take-off and landing in comparison with quadcopters, helicopters, and flapping-wing UAVs that can perform vertical take-off and landing (VTOL). Integrating a multirotor system with a fixed-wing UAV imparts VTOL capabilities without significantly compromising fixed-wing aerodynamic efficiency, endurance, payload capacity or range. Documented system design approaches to address various challenges of such fusion processes are sparse. This research proposes a holistic approach for designing, prototyping, and testing an electric-powered fixed-wing hybrid VTOL UAV. The proposed system design approach augments the standard aircraft design process with additional steps to integrate VTOL capabilities. Separate fixed-wing and multirotor designs were derived from the frozen mission requirements, which were then fused. The process used simulation for modeling and evaluating alternatives for the hybrid UAV created using standard aircraft design equations. We prototyped and instrumented the final design to validate operational capabilities through test flights. Multiple flight trials identified the ideal combination of Lithium-Polymer (Li-Po) batteries for VTOL (8000mAh) and fixed-wing (14000mAh) modes to meet the endurance and range requirements. The redundant power supplies also increased the survivability chances of the hybrid UAV during failures.
用于资产监控的电动固定翼混合垂直起降无人机的设计与实现
固定翼无人机(uav)提供了长距离或高耐力应用所需的最佳空气动力学效率,尽管与四轴飞行器、直升机和可以执行垂直起降(VTOL)的扑翼无人机相比,它们对起飞和降落的跑道要求更高。将多旋翼系统与固定翼无人机集成,在不显著损害固定翼气动效率、续航力、有效载荷能力或航程的情况下,赋予垂直起降能力。文档化的系统设计方法来解决这种融合过程的各种挑战是稀疏的。本研究提出了一种设计、原型和测试电动固定翼混合垂直起降无人机的整体方法。提出的系统设计方法增加了标准飞机设计过程的附加步骤,以集成垂直起降能力。分离的固定翼和多旋翼设计源自冻结任务的要求,然后被融合。该过程使用模拟建模和评估使用标准飞机设计方程创建的混合无人机的备选方案。我们对最终设计进行了原型化和仪器化,通过试飞来验证操作能力。多次飞行试验确定了垂直起降(8000mAh)和固定翼(14000mAh)模式的理想锂聚合物(Li-Po)电池组合,以满足续航力和航程要求。冗余电源也增加了混合型无人机在故障期间的生存机会。
