[0052] A cleaning method for a turbofan engine air flow channel, comprising the steps of:
[0053] S1. Determine the cleaning mode adopted
[0054] The timing of cleaning in the desalination cleaning mode is:
[0055] ①Continuous or frequent use in a salt spray environment, after 100 hours of flight, perform a desalination cleaning;
[0056] ②Long-term stay in areas with high concentration of salt spray: during strong wind and monsoon seasons, perform desalination cleaning once a month; during non-strong wind and monsoon seasons, perform desalination cleaning once every two months;
[0057] ③Salt core deposits on the surface of compressor blades, turbine disks, and airflow channels, and obvious pollution spots appear, and desalination cleaning is carried out;
[0058] The timing of cleaning in the performance recovery cleaning mode is:
[0059] ① When the engine has the following phenomena during use, if the effect is not obvious after mechanical adjustment, use the perform...
