本文介绍了一种危害飞行安全的小尺度风暴“微下击暴流”的特点。分析了它对飞机起飞和着陆的影响。同时介绍了下击暴流的模拟技术和利用流体动力学模型进行穿越风暴着陆的数学模拟结果,揭示了飞机在微下击暴流中的运动特点。作者还对今后的研究工作提出了建议以及指出了通过地面模拟试验培养飞行员处理和应付微下击暴流这种复杂气象环境能力的必要性。
This article describes the characteristics of a small-scale storm “microstreak” that endangers flight safety. Analyzed its impact on the take-off and landing of the aircraft. At the same time, the simulation technique of the downburst and the mathematical simulation of the landing through the storm using the hydrodynamic model are introduced, and the movement characteristics of the aircraft in the microburst are revealed. The author also puts forward some suggestions for future research work and points out the necessity of training pilot pilots to deal with and deal with the micro-storm outbreak in complex meteorological environment by ground simulation test.
