In view of the fact that there is no one that can comprehensively characterize the aerodynamic quality characteristics of military aerocraft, the concept of aerodynamic integrity is proposed for the first time and its research is carried out. It is believed that the aerodynamic integrity of military aerocraft can comprehensively characterize its aerodynamic mass characteristics in the process of combat use. Firstly, the process and definition of the concept of aerodynamic integrity are introduced, and the basic connotation and basic characteristics are discussed. It is believed that the aerodynamic integrity of military aerocraft is the basis of the combat effectiveness of aerocraft. The characterization method of Aerocraft aerodynamic integrity is introduced, and the main influencing factors of military aerocraft aerodynamic integrity are analyzed. The new concept of aerodynamic integrity of military aerocraft is introduced aims to provide reference for the development of military aerocraft design, manufacturing, testing and support in China.
