航空灭火机反应快速、灭火效能高,能在人力难以接近的地区执行灭火任务。世界各国广泛利用直升机、固定翼陆机、水机或水陆两用飞机组成护林灭火航空队。根据国务院领导的指示,在中央军委、总参、海军、林业部和航空部的支持关怀下,航空部水上飞机设计研究所和哈尔滨飞机制造厂将现役水轰五飞机改装成一架灭火机,于1987年11月17日地面投水试验成功,又于1987年12月16日首次试飞投水取得成功。 水轰五灭火机水箱容积8.3m’,投水高度30m～50m,投水速度210km/h。它可在适当水域滑行起飞中汲水,15～20s汲满水箱,随即飞赴火场灭火。可汲海水、淡水或添加阻火、
Aviation fire extinguisher fast response, high fire extinguishing efficiency, can be hard to reach in areas of human execution fire fighting tasks. Countries in the world make extensive use of helicopters, fixed-wing land-based aircraft, water or amphibious aircraft to form a forest fire fighting air force. According to instructions from the State Council, with the support and support of the Central Military Commission, the General Staff, the Navy, the Ministry of Forestry and the Ministry of Aviation, the Seaplane Design Institute of the Ministry of Aviation and the Harbin Aircraft Manufacturing Plant converted the active H5 aircraft into a fire extinguisher in 1987 On November 17, 2000, the test of water injection on the ground was successful and the first successful test flight on December 16, 1987 succeeded. Water bombing five extinguisher tank volume 8.3m ’, the water level of 30m ~ 50m, water rate of 210km / h. It can glide in takeoff in the appropriate waters draw water, 15 ~ 20s filled with water tanks, then flew to the fire fighting. Can absorb seawater, fresh water or add fire retardant,
