Aerodynamic force and moment in flight simulation are traditionally obtained through aerodynamic models hard-coded in calculation programs. Due to the coupling of aerodynamic models and calculation programs, considerable time and money are expended on the simulation reconstruction process in case of aerodynamic model changes. Therefore, the traditional method cannot satisfy modern flight simulation demands. Given the tree structure of aerodynamic models, the concept of aerodynamic model trees is proposed and a model storage format based on the characteristics of XML (MBX) is designed to store the aerodynamic model trees. MBX separates aerodynamic models from concrete calculation programs, leading to more efficient replacement and modification of aerodynamic models. Furthermore, it improves the universality of aerodynamic force and moment calculation, standardizing their solutions. As an exchange standard for aerodynamic models, MBX can reduce the transmission time of aerodynamic models between different institutions from staff-months to staff-days. In addition, it can expedite the process of modifying aerodynamic models to approach the actual aerodynamic characteristics of aircraft.
