摘　　要：现有的航空喷嘴通常有旋转离心雾化喷嘴以及液力雾化喷嘴两个种类。比较这两种喷嘴的雾化性能,可以看出旋转离心雾化喷嘴雾滴谱窄,更容易控制雾滴的沉积、抑制雾滴飘移,适合用于航空施药。在旋转离心喷嘴的喷雾性能研究的基础上,总结旋转离心喷嘴的雾化机理,选择研究雾化性能的新型研究方法和测试手段。为研究和改进航空施药的窄雾滴谱航空喷嘴提供参考。Rotary atomizer and hydraulic nozzle are commonly used in aviation spray.Atomization performance of the two nozzles were compared,the droplets deposition could be easy controlled and the pesticide drift could be reduced with rotary atomizer,which had narrow spectrum and was more suitable for aviation spray.Based on the study on atomization performance of rotary atomizer,the characteristics and spray mechanism were summarized,and then some new research methods and test instruments were found.The reference to study and improve the key components of aviation spray was provided in this paper.
