The invention provides an air rudder leading edge thermal stress release structure and an aircraft. The air rudder leading edge thermal stress release structure comprises an air rudder leading edge, an air rudder base body, a countersunk screw, a countersunk nut, a long round hole and a round hole. The air rudder front edge is connected with the air rudder base body through a countersunk screw matched with a countersunk nut, a round hole is formed in the middle of the side, connected with the air rudder front edge, of the air rudder base body, and long round holes are formed in the two sides of the round hole in the length direction of the side, connected with the air rudder front edge, of the air rudder base body. The countersunk head screw and the countersunk head nut are installed in the long round hole or the round hole. Through the design of the oblong holes and the round holes, the thermal stress between the air rudder base body and the air rudder leading edge can be released on the premise that the positioning requirement of the air rudder base body and the air rudder leading edge is met, and the strength and reliability of the overall structure of the air rudder are improved.
