In order to meet the technical requirements of amphibious aircraft flight safety

total life of the fuselage structure and the interval between repairs

for the harsh operating environment of the amphibious aircraft and the characteristics of the failure of the protection system of the typical structural parts of the aircraft

refer to similar domestic and foreign protection technology methods

according to corrosion Pre-research results of protection and control

comprehensive governance of the SH–5 Maritime Bomber and domestic and foreign civil aircraft engineering application experience

comprehensive consideration of specific engineering applications

through materials selection

surface protection

anti-corrosion sealing

ventilation and drainage

corrosion inhibitor selection and other technologies application research

we carry out the application research on corrosion protection and control technology of amphibious aircraft according to the corrosion protection thought of the whole life cycle. Up to now

the surface protection and sealing of the base structure are normal and effective. The results of the selection and verification of the protection system and the water-tight and oil-tight tests show that the application of this protection technology has achieved the anti-corrosion development goal of the first renovation of 6 years.
