DA42NG飞机复合材料三四级损伤修理流程分析

Analysis of the Process of Repairing the Three-and Four-Level Damage of the Composite Materials of DA42NG Aircraft

DN42NG飞机由奥地利钻石飞机公司设计制造,机身、机翼、安定面、操纵舵面等结构均为复合材料。某校大量采购了DN42NG飞机作为中教机使用。随着飞机运行量的增加,各分院的DA42NG飞机已经出现飞机表面漆层甚至复合材料划伤、裂纹、破孔等损伤,并且随着飞机运行量的进一步增加,鸟击、碰撞等外来物撞击带来的损伤以及日常飞行训练造成的损伤也将会继续增加。因此,针对DA42NG飞机三四级损伤修理的流程进行分析和研究具有重要意义。

The DN42NG aircraft was designed and manufactured by Diamond Aircraft Corporation in Austria,and its fuselage,wings,stabilizers,control surfaces and other structures were composite materials.A university purchased a large number of DN42NG aircraft as intermediate trainers.With the increase of aircraft operating capacity,DA42NG aircraft in each school has already appeared scratches,cracks,holes and other damage on the surface paintcoat and even composite materials of aircraft,and with the further increase of aircraft operating capacity,the damage caused by foreign object impacts such as bird strikes and collisions and routine flight training will continue to increase,so it is of great significance to analyze and study the process of repairing the three-and four-level damage of DA42NG aircraft.
