Research on aerodynamic integrity of military aircraft

The aerodynamic integrity of aircraft can comprehensively characterize the aerodynamic mass characteristics of aircraft during service（combat）use. However，there is currently no index that can comprehensively characterize the aerodynamic mass characteristics of aircraft. Therefore，the concept of aerodynamic integrity of military aircraft is first proposed and studied：during the operational use of military aircraft，the aerodynamic shape can be maintained intact，and the flight performance，quality，and control can meet and maintain the required attributes. 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 aircraft is the basis of the combat effectiveness of aircraft. The characterization method of aircraft aerodynamic integrity is introduced，and the main influencing factors of military aircraft aerodynamic integrity are analyzed. The new concept of aerodynamic integrity of military aircraft is introduced aims to provide reference for the development of military aircraft design，manufacturing，testing and support in China.
