In view of the fact that a certain type of aircraft lacks a unit tactical training simulator, a PC-based unit tactical training simulation system for a certain type of aircraft is designed. An integrated simulation platform based on open universal interface data unit soft bus and distributed configurable components is used to build a high fidelity avionics weapon simulation model, which solves the key problems such as driving rod force simulation, visual jitter, head-up display, sound simulation and so on, which are highly related to the use experience of trainers. The application results show that the system can provide tactical confrontation simulation training close to actual combat, with low cost and easy maintenance. It has strong practical value and promotion significance.
