Abstract:LVC training is one of the important means for military powers to achieve joint tactical confrontation at low cost and systematically. In order to expand the tactical training tasks of the trainer aircraft, improve the training efficiency and reduce the training cost, an LVC training system with the characteristics of the trainer was studied. This paper analyzes the concept, training capability and technical connotation of LVC training system for foreign fighter and trainer aircraft, and focuses on the system architecture, technical architecture and key elements of LVC training for advanced trainer aircraft. Based on the LVC training architecture of the advanced training aircraft, combined with the actual situation, the LVC principle demonstration and verification environment of the advanced training aircraft is briefly explained. The communication protocol and interaction logic between the implementation node, simulator node and virtual soldier node in the training machine system are verified by simulation. The results show that the analysis of the LVC training structure and key elements of the advanced trainer meets the engineering requirements, and provides technical support for the construction of the LVC training system of the trainer.
