摘要
报道新研制的ＨＵ２－ＨＷ１型超低容量喷洒设备与海燕６５０Ｂ飞机配套的技术参数的测试方法和结果。在超音速风洞实验室，用来流风速２７ｍ／ｓ和３３ｍ／ｓ，测试１号雾化头转速依次为７４６０、９３５０ｒ／ｍｉｎ；２号雾化头为８４１０、１１８００ｒ／ｍｉｎ。药液泵压力３．５～５．０ｋｇ／ｃｍ２，流量１５．０～２１．０Ｌ／ｍｉｎ。有效喷幅４０ｍ，雾滴粒径９５～１７０μｍ，雾滴密度平均９～１６滴／ｃｍ２，雾滴均匀系数为０．７７。说明新研制的ＨＵ２－ＨＷ１型超低容量喷洒设备主要装置的性能良好。
This paper reported the test methods and results of the technical properties of the HU2 HW1 spraying equipment of ultra low volume when being equipped with the petrel 650B motor glider. No.1 and No.2 rotary atomizer were tested in the laboratory wind cave of supersonic speed of 27 and 33 m/s. The rotational speed of No.1 rotary atomizer was at 7 460 and 9 350 rpm respectively,and that of the No.2 was at 8 420 and 11 800 r/min respectively. The pump pressure was between 3.5 and 5.0 kg/cm 2,and the flow rate was 15.0～21.0 L/min. The swath width was 40 m. The droplets size was 150～170 μm (volume median diameter),and the number of droplets per cm 2 was 9～16. The droplets ratio of diffusion was 0.77.All the results showed the properties of the HU2 HW1(ULV) when being equipped with the petrel 650B motor glider were excellent.
