- 基于结构与气动仿真进行模块化设计，确保多飞行模式稳定性
- 通过重心与中性点位置控制，实现悬停稳定与前飞正安定
- 验证了推力功率分析结果，实测性能符合仿真预期
倾转旋翼双旋翼无人机结合固定翼与旋翼技术优势，具备长续航和垂直起降能力。但此类飞行器需优化设计以保障静力学与动力学稳定性。本文基于大量分析与深入的结构及气动仿真，开发了传统双旋翼机的模块化设计。结构分析确保机体在不同飞行模式下能承受应力。控制重心（CG）与中性点（NP）相对位置是设计关键，确保悬停时稳定及前飞时正安定。进行了推力与功率分析以评估飞行性能与续航能力。完成分析后研制出样机，并使用基础飞控系统进行飞行测试，验证了仿真所得性能指标。
原文摘要 · Abstract (English)
Hybrid systems like tilt-rotor bicopter drones combine the beneficial characteristics of both fixed-wing and rotary-wing technology, enabling long endurance and VTOL capability. However, such drones also require an optimum design to ensure both static and dynamic stability. The modular design of a traditional bicopter is developed in this paper based on extensive analysis and in-depth structural and aerodynamic simulations. The structural analysis has been performed to ensure that the aircraft's structure withstands the stresses encountered during different flight modes. Controlling the relative positions of the Center of Gravity (CG) and Neutral Point (NP) is an essential aspect of the design, ensuring stability during hover and positive stability during forward flight. The thrust and power analyses have been conducted to assess the flight performance and endurance. After analysis, the drone has been developed, and flight tests with a basic flight controller were conducted to validate the performance metrics obtained in the simulation.
