摘要:为提升复合翼物流运输无人机的垂直飞行性能并延长悬停续航时间，提出了一种混合动力复合翼无人机的整体布局和动力推进系统设计方法，并成功开发出工程样机及适配地面台架。根据具体任务需求，设计了串联直驱式混合动力系统结构，并制定了功率输出模式。在考虑机翼载荷和推重比等结构约束条件下，给出了固定翼模式起飞质量和机翼尺寸的估算方法，并利用Profili软件选择了适用于低速飞行的USA-35B翼型；同时探讨旋翼和变距推进桨的选型方法，并通过地面试验台获得最优巡航桨叶角。通过仿真试验与地面测试验证了动力系统、电气传动系统及机械结构的可行性。经过样机试飞验证，所设计的复合翼无人机实现24 min悬停，在垂直飞行性能方面较业界平均水平有显著提高。
Abstract:In order to improve the logistics transportation capabilities of composite wing unmanned aerial vehicle（UAV）， a design methodology for the overall layout and power propulsion system of a hybrid wing UAV was proposed to enhance its vertical flight performance and extend hover duration. Furthermore， successful development of an engineering prototype and an adaptive ground platform was achieved. In accordance with the specific task requirements， the structure of a series direct drive hybrid power system was designed and the power output mode was formulated. Considering structural constraints such as wing load and thrust-to-weight ratio， an estimation method for take-off weight and wing size in fixed-wing mode was provided. The USA-35B airfoil suitable for low-speed flight was selected using the Profili software. Simultaneously， selection methods for rotors and variable pitch propellers were discussed， and the optimal cruise blade angle was determined through ground testing. The feasibility of the power system， electric transmission system， and mechanical structure was validated through simulation experiments and ground tests. Following prototype test flight verification， the designed composite wing UAV demonstrates a hover time of 24 min， exhibiting significantly improved vertical flight performance compared to industry standards.
