The invention discloses a variable
swept wing fighter plane. The variable
swept wing fighter plane comprises a plane body; a
radar radome is arranged at the front end of the plane body; an
airspeed tube is arranged at the front end of the
radar radome; a
cockpit is arranged in the part, positioned at the rear end of the
radar radome, in the plane body; a
dorsal fin is arranged the part, on the rear side of the
cockpit, at the top of the plane body; canard wings are arranged in parts, positioned on two sides of the
dorsal fin, of side edge positions of the plane body; variable swept wings are arranged on the rear sides of the canard wings;
tail wings are arranged on parts, positioned on the rear sides of the variable swept wings, of two sides of the
tail part of the plane body; a
tail jet is arranged at the tail part, between the two tail wings, of the plane body; a vertical tail is also arranged onthe plane body part between the tail jet and the tail wings; wing roots,
leading edge flaps and
trailing edge flaps are arranged on the variable swept wings; the
leading edge flaps and
leading edge slats are connected with each other and are on the same straight line; and spoilers are arranged on the variable swept wings on the internal sides of the
trailing edge flaps. The variable
swept wing fighter plane has the advantages that the commissioned swept wing fighter plane can enter a swept forward wing during fighting to enhance the near-space fighting capacity of the fighter plane; and moreover, missiles can be launched from multiple angles by using a rotatable telescopic
missile pylon so that the fighting capacity of the fighter plane is greatly enhanced.
