| 摘要: |
| 森林火灾地空配合扑救技术是指直升机吊桶在火场上空洒水，地面扑火人员及时跟进扑救，互相配合，共同扑灭森林火灾的方法。文章介绍了在森林火灾地空配合扑救技术中运用K-32直升飞机开展的吊桶洒水有效性测试、吊桶洒水有效性与火场温度变化的关系。结果表明，在消防烟雾弹的引导下，K-32直升飞机能对准测试区域进行洒水作业。K-32直升飞机吊桶以垂直距离火场10～20 m高度洒水，水量集中，灭火效果较好；K-32直升飞机吊桶洒水落点准确率的高低对火灾扑救效率影响极大，当落点滞后100 m时，飞机经过火场上空导致火场温度急剧升高130 ℃左右。 |

| Abstract: |
| The forest fire extinguishing technique of ground-air cooperation refers to the mutual cooperation of the helicopter lifting?the?bucket?of?water?to drop onto?a burning forest and timely follow-ups of ground firefighters fighting in the process of putting out a forest fire. In this paper, the validity of the bucket sprinkler in K-32 helicopters was introduced, and the relationship between the effectiveness of the bucket and the firing temperature was discussed. The results showed that the K-32 helicopter could be directed at the test area for watering operations under the guidance of fire-drill smoke bombs. When the K-32 helicopter bucket at 10 ~ 20 m height vertical distance of fire scene, a?good?effect?of?extinguishing fire?could be?obtained. Fire extinguishing efficiency was greatly affected by the accuracy of the landing position of bucket watering, when the landing position was 100 m away from the pointed location, helicopter flying over the fire scene will raise about 130 ℃ of fire scene instead. |
