Abstract

As an important ammunition, JDAM ammunition needs to study its trajectory and model characteristics. On the basis of professional theories such as launch dynamics, ballistics, flight stability, vibration theory, multi-body system kinematics, aerodynamics, etc., this paper proposes a design method and system for the JDAM ammunition digital model library. The module library includes the system portal, the ammunition model library, the model calling interface and the knowledge base. The module library are established to complete the construction, calculation and management of the digital models of various types of JDAM ammunition. Combined with the actual project, good results are obtained. JDAM ammunition digital model library can realize the accurate simulation of trajectory, significantly improve the accuracy of trajectory simulation, and then improve the simulation accuracy of aircraft ground fire attack, and provide accurate data for three-dimensional display. For various types of JDAM ammunition, JDAM three-dimensional digital models and related mathematical models with different granularity are constructed to provide support for trajectory solution and model display. In addition, JDAM ammunition digital model library also provides support for relevant simulation and effectiveness evaluation. In the follow-up work, a more accurate ammunition digital model library can be constructed in combination with the actual data.
