This paper discusses about the critical situations faced by the Defence operations with drones in the area of Siachen Glacier in the Himalayas. The reasons for the structural failures in drone’s rotor blades and the low-performance efficiency of the drones at low-temperature conditions are highlighted. A possible solution to the above-mentioned problems has been addressed by introducing a new boundary design in the rotor blades and composite materials. The results which are shown in this paper are obtained by the computational analysis facility located at the Department of Aerospace Engineering, School of Technology, GITAM (Deemed to be University), Hyderabad. By mimicking the Siachen Glacier atmosphere conditions, the proposed rotor blade design has been analysed in CFD.

国防应用中低温条件下无人机动叶片的计算设计分析

本文讨论了在喜马拉雅山的Siachen冰川地区，国防行动中无人驾驶飞机面临的严峻形势。强调了无人机转子叶片结构故障的原因以及无人机在低温条件下效率低下的原因。通过在转子叶片和复合材料中引入新的边界设计，已经解决了上述问题的可能解决方案。本文显示的结果是通过位于海得拉巴GITAM（据认为是大学）技术学院航空工程系的计算分析设备获得的。通过模仿Siachen冰川的大气条件，在CFD中对建议的转子叶片设计进行了分析。
