Analysis of the Process of Repairing the Three-and Four-Level Damage of the Composite Materials of DA42NG Aircraft
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 paint-coat 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 in-crease,so it is of great significance to analyze and study the process of repairing the three-and four-level damage of DA42NG aircraft.
