直升机航电系统高原高寒环境适应性评估

目的研究高原高寒环境对直升机航电系统试验的影响、应对以及直升机环境适应性评价方法。方法通过分析高原高寒环境对直升机航电系统的影响因素,建立评价指标体系,运用模糊综合评价方法,得出直升机航电系统在高原高寒环境下适应性评价值。结果直升机高原高寒适应性可分为两个一级指标,12个二级指标,其中高原适应性评价指标的权重为0.7983,高寒适应性的权重指标为0.2135。某直升机高原高寒适应性模糊综合评价值为0.7692,适应性综合评价为较好。结论高原、高寒地区特殊的自然环境、地形地貌、气候条件等都会对航空装备的试验和使用产生很大的影响,航空装备乃至武器装备环境适应性试验的重要性与日俱增,运用模糊综合评价方法能够有效地进行直升机航电系统高原高寒环境适应性评价,提高试验效率。

Evaluation of Plateau and Alpine Environment Adaptability of Helicopter Avionics System

Objective To study on the influence of plateau alpine environment on helicopter avionics system test, response and helicopter environmental adaptability evaluation method. Methods By analyzing the influencing factors of the plateau alpine environment on the helicopter avionics system, the evaluation index system was established; and the fuzzy comprehensive evaluation method was used to obtain the adaptability evaluation value of the helicopter avionics system in the plateau alpine environment. Results The plateau alpine adaptability of the helicopter can be divided into two first-level indicators and 12 second-level indicators. The weight of the plateau adaptability evaluation index was 0.7983, and the weight index of the alpine adaptability was 0.2135. The fuzzy comprehensive evaluation value of a helicopter''s alpine adaptability was 0.7692, and the comprehensive evaluation of adaptability was good. Conclusion The special natural environment, topography and climatic conditions in the plateau and alpine regions will have a great impact on the testing and use of aviation equipment. The importance of aviation equipment and even environmental adaptability testing of weapons and equipment is increasing day by day. The fuzzy comprehensive evaluation method can effectively evaluate the adaptability of plateau alpine environment of helicopter avionics system and improve the test efficiency.
