摘　　要：北方大范围层状云和混合云飞机人工增雨(雪)是解除干旱、森林灭火、改善生态环境的重要途径之一。研制的L-1型机载19管多星体拖曳式焰弹催化系统可满足上述需求。该系统由多星体焰弹弹体、AgI焰剂、发射装置和电控装置构成。试验和初步应用证明,该系统工艺稳定、操作简便、发射成功率100%,催化剂成核率在-8℃时高达1015个/g,入云5 min内90%的核即可活化,携弹量760枚,可连续作业4 h以上,后向发射,作业方式灵活。与目前使用的龙B-2型焰弹催化系统相比,该系统是一种新型优越的催化系统。The aircraft weather modification in large-scale stratiforra clouds and mixture clouds in North China is one of the important ways to relieve droughts and forest fires and improve the natural environment. The self-developed L-1 Seeding System of Air-borne Towed Flame with Multiple Warheads and 19 Pipes can meet the needs of precipitation enhancement operations. The system consists of the multiple warhead ammunition body, AgI catalyst, and launching and power control units. According to the experiments and primary application, the system shows obvious features of stable, easy to operate, and 100% launch rate. The nucleus rate is high up to above 1015 kg AgI at - 8℃ and the 90 % nucleus can be activated in 5 minutes after getting into clouds. The launcher can carry 760 flares so as to seed for 4 hours ceaselessly and can shoot backward. The Long B-2 flame seeding system used presently has just 90 % launch rate, and the launcher can carries only 200 flares, operating for only 1.5 hours and shoots laterally with less flexibility, so mechanical failures occurs frequently.
