目前,飞机撒化肥在加拿大已成为森林经营管理的一项有效措施。其方法是使用205型——贝尔直升飞机和一个吊在机腹下货钩上的康奈尔颗粒化肥撒料器。撒料器的主要技术数据为:容积2.27立米;空重220公斤;高度183厘米;直径168厘米;流速31公斤/秒;带宽60米。化肥通过撒料器的调节式进料口流进离心式推进器,推进器的动力来自轻型双行程引擎,其转数由电子自动调速器控制。
At present, aircraft spreading fertilizer in Canada has become an effective measure for forest management. The method is to use a Type 205 Bell helicopter and a Cornell pellet dispenser suspended from under the belly. Sprinklers main technical data: Volume 2.27 cubic meters; empty weight 220 kg; height 183 cm; diameter 168 cm; flow rate 31 kg / s; bandwidth 60 meters. The fertilizer flows into the centrifugal thruster through the adjustable feed port of the spreader, powered by a light, two-stroke engine whose rpm is controlled by an electronic automatic governor.
