The US Air Force (USAF) tested a new fuselage boom configuration on the C-130H airplane. We used into-the-wind and crosswind field trials to characterize a BVA oil (BVA Inc, Wixom, MI) droplet spectra produced by fuselage booms with flat-fan nozzles (8001, 8005) at the Air Force Range at Avon Park, FL. Across all trials, median droplet diameter (DV50) for 8001 and 8005 nozzles were 11.4 microm and 54.3 microm, respectively. For 8005 nozzles 22% of droplets collected were 7 microm to 25 microm size range while 75% of droplets from 8001 nozzles were < 7 microm. Fuselage configuration parameters and field data were also used as input variables into the Agricultural Dispersal (AGDISP) computer model to predict aerosol deposition and droplet fate. AGDISP predictions were compared with field data from crosswind tests and the model was found to fit reasonably well to empirical data. However, AGDISP predictions were better correlated with empirical findings for larger droplets than smaller droplets and for locations closer to the release point than further downwind.
美国空军（USAF）在C - 130H飞机上测试了一种新的机身喷杆配置。我们在佛罗里达州埃文帕克空军靶场进行了迎风和侧风实地试验，以表征配备扁平扇形喷嘴（8001、8005）的机身喷杆产生的BVA油（BVA公司，密歇根州威克瑟姆）液滴谱。在所有试验中，8001和8005喷嘴的中位液滴直径（DV50）分别为11.4微米和54.3微米。对于8005喷嘴，收集到的液滴中有22%在7微米至25微米尺寸范围内，而8001喷嘴的液滴中有75%小于7微米。机身配置参数和实地数据也被用作农业喷洒（AGDISP）计算机模型的输入变量，以预测气溶胶沉积和液滴去向。将AGDISP预测结果与侧风试验的实地数据进行了比较，发现该模型与经验数据拟合得相当好。然而，AGDISP预测结果与较大液滴的经验结果相关性更好，而与较小液滴以及离释放点较近位置的相关性优于离下风向更远位置的情况。
