摘要
挂载在机舱下面的碘化银播撒器,前面的进气口大,而后面的出气口小,在进气口与出气口之间有1.5 m的通气道连通,在这个通气道里有一个通气管与播撒器的储液罐相通.充分利用飞机高速飞行时,由于进气口大,出气口小,从而在进气口与出气口之间的通气道里产生动气压,这个动气压通过连接播撒器储液罐的通气管直接作用于储液罐里的碘化银溶液,当增雨作业飞机进入云层作业时,打开机舱里碘化银播撒器的控制仪,播撒器储液罐里的碘化银溶液在动气压的作用下由安装在后面的喷嘴向外播撒,实现了飞机人工增雨作业的自动化.
Airborne silver iodide seeding implement,hitched under the cabin,has big orifice of air inlet in the front and small ones of air outlet in the rear.There is a 1.5 meters airing pipeline to connect air inlet and air outlet,in which a airing pipe communicate with solution reserve tank of seeding implement.when the aeroplane flys at a high speed,it will engender dynamic pressure in the airing pipeline between big air inlet and small air outlet,and then the dynamic pressure act on the silver iodide solution in the reserve tank.As aeroplane for artificial precipitation works above the cloud,the seeding-control apparatus in the cabin is turned on,silver iodide solution in the reserve tank will be sprayed out by dynamic pressure through sprayer fixed at the back,then robotization for aircraft artificial precipitation operations will be realized.
