摘　　要：航空活塞发动机配置螺旋桨是目前低速中低空无人机中最为常见的一类动力推进系统,本文对这类动力推进系统的设备选型和性能匹配方法进行了研究,通过数学模型和经验数据计算分析发动机和螺旋桨的性能匹配参数,并以某型中空长航时无人机为例,对动力推进系统性能匹配的关键参数如发动机最大可用功率、发动机最高转速、起飞滑跑过程的推力水平和螺旋桨效率进行了评估和量化分析。The kind of propulsion system of piston aero-engine and propeller is popular in low-speed UAV for lowand middle-altitude. The method of selection and performance matching for UAV propulsion system was researched based on mathematical model and experience data in this paper. The key characteristics of performance matching such as maximum available engine power, maximum engine speed, thrust level during UAV takeoff, propeller efficiency were specified and quantitatively analyzed on the basis of a certain type of middle-altitude long-endurance UAV.
