Corrosion Protection and Repairing Countermeasures of Internal Structure of a Certain Type of Helicopter

Objective To promote the ability of corrosion protection of a certain type of helicopter and carry out the research on corrosion protection and repair of internal structure of the helicopter. Methods The cause analysis was carried out on the area of corrosion and corrosion condition, and corresponding countermeasures and suggestions were put forward. Results The main bearing box and purlin of this helicopter did not appear serious corrosion, which had good foundation for prolonging service life. Conclusion The type of helicopter gradually entered the stage of aging and the corrosion showed a trend of rapid development. More attention needed to be paid in the use and maintenance in the future.
