The invention relates to a deformation rudder blade with a self-adaptive deflection leading edge and a deflection method thereof. The deformation rudder blade comprises a rudder blade body and a deflection device; the rudder blade body comprises a first side wall, a second side wall and a leading edge wall, wherein the first side wall and the second side wall intersect to form a trailing edge; the two ends of the front edge wall are connected with the ends, away from the trailing edge, of the first side wall and the second side wall correspondingly, and the deflection device is arranged on the side, away from the trailing edge, of the front edge wall, used for changing the front edge deflection angle of the rudder blade and comprises a plurality of rudder layer deflection assemblies. The deflection assemblies are distributed on the side, away from the trailing edge, of the front edge wall at intervals in the length direction of the trailing edge. According to the deformation rudder blade with the self-adaptive deflection front edge and the deflection method of the deformation rudder blade, in a complex water body, the deflection angles of the multiple layers of deflection assemblies can be flexibly changed according to the actual inflow angles and the inflow speeds of the water body at different heights in the vertical direction; the front edge of the rudder blade can generate better hydrodynamic performance in a complex and non-uniform propeller rear wake flow field environment.
