Aiming at the problem of fixed-wing aircraft vulnerability, a database software of fixed-wing aircraft target vulnerability model is developed. On the basis of analyzing the target characteristics of typical fixed-wing aircraft, the damage level is divided, the vulnerability model of fixed-wing aircraft is established by using 3D modeling technology, and the damage criteria and criteria are determined; The database structure of fixed-wing aircraft vulnerability is designed by using relational database, and the visual simulation interface is provided in the integrated development environment to realize the unified format storage and fast query of data and models, which is verified by an example. The results show that the software can realize the rapid query and management of fixed-wing aircraft target vulnerability data, and provide a reference for fixed-wing aircraft target damage assessment.
