使用直升机直接机降人员进行灭火,是现代化的护林手段之一。但是,高原林区实施机降灭火,如何选择好机型,是非常重要的问题。为了探索在高原林区使用直升机进行机降灭火的经验,我站连续两年先后在云南的思茅、四川的西昌、广西的百色三个基地进行了机降灭火试验,共组织直升机飞行281小时,机降174架次。使用的机型有米—8、海豚(直九)、贝尔—212。由于上述三林区所处纬度不同,地理环境不一,海拔、气温、风向、风速
Use of helicopters direct crew down for fire fighting, is one of the means of modern shelter. However, the implementation of high altitude forest fire extinguishing machine, how to choose a good model is a very important issue. In order to explore the experience of using helicopters for aircraft fire suppression and reduction in highland forest areas, I conducted flight test and fire extinguishing tests for three consecutive years at Simao, Yunnan, Xichang, Sichuan and Baise, Guangxi. We organized a helicopter flight for 281 hours, Machine down 174 sorties. The models used are Mi -8, Dolphin (straight nine), Bell -212. Due to the different latitudes of the three forest areas, different geographical environments, altitude, temperature, wind direction and wind speed
