Abstract
A laser shock peening method and device for a bottom surface of a tenon groove of an aircraft blade. During the laser shock peening process, according to geometric characteristics of the bottom surface of a tenon groove, a circular facula of a laser beam is changed into a strip-shaped facula, at the same time as a flow-guiding injection device and a water pumping device are respectively arranged at two end surfaces of the bottom surface of the tenon groove to ensure the stability of a water confinement layer.
