农林飞机结构抗坠毁设计技术

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。

Structure Anti-crash Design technique for Agriculture Airplane

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 flying at super-low altitude,but also anti-crash capability.Aiming at the probable bump and crash when agriculture aircraft is performing its task,this paper discusses agriculture airplane anti-crash design technique and calculation and analysis simulation technique.
