中文摘要:
      中空长航时无人机具有诸多优点,可用于执行多种军事及民用任务,已成为各国的研发热点。为使中 空长航时无人机在各个飞行阶段均具有良好的动力性能和经济性能,提出为航空活塞式发动机匹配恒速螺旋 桨的方法;根据发动机速度特性曲线、耗油率特性曲线选出发动机各经济工况点,在无人机飞行高度-速度包 线内对比分析各螺旋桨在选定发动机经济工况点的效率,并进行全尺寸发动机-螺旋桨风洞试验。结果表明: 本文研究方法适用于为已初步选定的活塞式发动机选配最佳的恒速螺旋桨。
英文摘要:
      In order to make the medium-altitude, long-endurance (MALE)UAV have good dynamic and economic performance in all flight stages, combining the speed characteristic curve, fuel consumption characteristic curve of piston engine and propulsion characteristic curve of propeller, the method of matching constant speed propeller for aero-piston engine is proposed. According to the speed characteristic curve fuel consumption characteristic curve of piston engine, the economic working points of the engine are selected and then efficiencies of each propeller on the economic working points above are compared and analyzed. Wind tunnel tests of full-scale engine and propeller showed that the proposed method could be used to select optimal constant propeller for piston engine which had been preliminarily selected.
