Research on Aviation Combat Simulation Based on STK and FMI

With the integration of avionics system from single platform to multi-platform into a larger and highly complex system, the technical requirements of avionics system are more complex, more extensive, and higher precision requirements. In the field of model-based systems engineering, the rationality verification of requirements by analysts and the performance verification of algorithms and functions by professional designers have always been the key considerations for quality assurance of design process. This paper develops a set of general aviation combat simulation platform. Through Socket interface in STK, STK/Connect module is used to obtain real-time information of combat objects in STK scene, and this information is sent to FMU file generated by Simulink or Rhapsody for solving. The calculated data is sent back to the combat scene through the interface again, and the state of the combat object is updated to realize the real-time digital battlefield calculation and simulation. The aviation combat simulation platform can receive the relevant data of the system equipment in the given combat scenario. By designing verification models and connecting them with combat scenarios, professionals can verify the rationality of combat plans and equipment performance requirements, as well as verify the performance of simulation algorithms and functions that meet the actual requirements. This method also supports the adjustment of the combat strategy through the combat results, to optimize the combat performance.
