The type 220 Medium speed target aircraft has an excellent integrated aerodynamic layout design, and is capable of medium-low altitude and high-subsonic flight. The RCS radar scattering area is small, which is helpful for the air defense missile force to shoot and train the target with high subsonic and low radar characteristics. The inner part of the nose can be equipped with a longbo ball to increase the radar scattering area, which can be used to simulate the characteristic effects of different targets. The lower part of the fuselage can carry light tube and decoy, which is convenient for the effective acquisition and firing training of infrared guided weapon. The whole machine system adopts modular design, parts have high interchangeability, easy to repair and maintenance in the later use.
