Device and method for strengthening aero-engine blade through pulsed magnetic field

The invention provides a device for strengthening an aero-engine blade through a pulsed magnetic field, and the device comprises a magnetic collector device which is disposed in a discharge loop and is used for amplifying the current in the discharge loop; the aero-engine blade is arranged in the middle of the magnetic collector; the insulating layer is arranged between the magnetic collector and the aero-engine blade; the insulating layer has the effect of preventing current conduction between the magnetic collector and the aero-engine blade; the carbon fiber composite tightening barrel is arranged on the periphery of the magnetic collector; the invention further provides a method for strengthening the aero-engine blade through the pulsed magnetic field. Aiming at the characteristics of special shape and curved surface of the aero-engine blade, a magnetic collector of which the two sides follow the shape and are tightly attached to the to-be-strengthened blade is adopted, and the surface of the blade is stre
