农林飞机结构抗坠毁设计技术

Structure Anti-crash Design technique for Agriculture Airplane

农林飞机通常在3-5m的超低空进行作业飞行,在离地面3m以上的空中往往会有树木、电线杆、电线、堤坝、土堆、山丘、建筑物等障碍物,稍有不慎,就有与之撞击的可能。这样的工作条件除要求飞机具有良好的超低空飞行性能以外,还要求飞机具有一定的耐坠撞能力。本文针对农林飞机执行任务过程中可能发生的碰撞、坠毁等特点,研究了农林飞机抗坠毁设计技术、计算分析仿真技术。

Agriculture Airplane usually performs its tasks by flying at super-low altitude of 3 -5 meters, and there are always obstacles such as trees, poles, wires, dykes and dams, soil piles, hills, buildings with height of more than 3 meters away from ground, so it is easy for airplane to bump onto these obstacles. In such a working condition, it is required that airplane has not only excellent performance on crash capability. Aiming at the probable bump flying at super -low altitude, but also anti, and crash when agriculture aircraft is performing its task, this paper discusses agriculture airplane anti - crash design technique and calculation and analysis simulation technique.
