The invention provides a heat-proof integrated aircraft rudder wing and an additive manufacturing method thereof. The aircraft rudder wing comprises a front cone, a gradient transition area, a rudder wing surface and a rudder wing shaft. The manufacturing method comprises the following steps: (1) carrying out laser melting deposition on the titanium alloy rudder airfoil, the airfoil cover plate and the rudder shaft; (2) welding the wing surface cover plate on the rudder wing cooling flow channel by adopting a welding technology; (3) titanium alloy/high-temperature alloy gradient transition area laser melting deposition forming is carried out on the basis of the titanium alloy rudder airfoil; (4) selective laser melting forming of a rudder wing front cone structure powder bed; (5) welding the front cone of the rudder wing to the gradient transition area to form a rudder wing blank; and (6) the welded rudder wing blank is subjected to post-treatment procedures such as overall heat treatment and machining. According to the invention, an additive manufacturing method is adopted, so that the integrated manufacturing of the material/structure/function of the rudder wing of the ultra-high-speed aircraft can be realized.
