文章通过在森林火灾扑救实地演练火场边缘设置定点可折叠水囊,并采取水囊加固技术,使用K—32与M—26直升机进行吊桶定点投水试验,测试在地面有烟雾、能见度较差的情况下,两种机型通过地面引导对定点水囊投水的准确性与投水效率,验证在森林火灾扑救过程中进行地空配合定点投水的可行性,并比较两种机型对定点投水技术的适用性。试验证明,在相似的地面环境条件下,由地面标识物引导,两种机型均能较准确地向加固后的水囊投水;K—32直升飞机投水准确率、投水有效率优于M—26直升飞机,是南方森林火灾地空配合扑救定点水囊投水的优选机型。
The article set the fixed folding water sac on the edge of field fire fighting field fire fighting in forest firefighting and adopted water-bladder reinforcement technology to carry on the fixed-point watering test of bucket with K-32 and M-26 helicopters. The smoke on the ground was tested and the visibility was poor In the case of two models, the accuracy and efficiency of water delivery to the fixed-point water sacs were guided by the ground to verify the feasibility of fixed-point watering with air and ground during the process of forest fire suppression and comparison. Application of water technology. Tests show that under similar ground conditions, guided by ground markers, both models can more accurately water to the reinforced water sac; K-32 helicopter water casting accuracy, water efficient Better than M-26 helicopters, is the southern forest fire with air and water jet fixed-point selection of the preferred model.
