摘　　要：为解决无人机发动机高度特性,首次提出并研制出了应用在TILLOTSON膜片式化油器省油器上的高度补偿器,其结构轻巧并能自动调节,装机后使耗油量减少,从而使得巡航高度增加且留空时间增长;推导出了满足工程要求的补偿器截流量校核方法。大量飞行实验结果表明,改进后的化油器其结构合理,效果明显,较大程度缓和了巡航高度与续航时间的矛盾。To improve the altitudinal performance of UAV gasoline engines, for the first time the authors propose and develop a design of altitude compensator （AC） for the TILLOTSON diaphragm carburetor economizer. The mechanically automatic adjustment of the AC together with its light structure leads to an apparent reduction in the fuel consumption, meanwhile enhancing the flight altitude and time greatly. Furthermore a calibration method of the AC intercepting fuel mass has been derived, being beneficial for the engineering requirement. The results from great many of flight experiments we demonstrate that the improved or modified carburetor with rational structure and high efficiency can resolve the contradiction problem between the UAV cruise height and the sustainable time.
