In a typical air combat encounter scenario, it is not only the flight performance, detection capability, and battlefield support capability of the carrier aircraft platform that affects the outcome of the battle, but also the human factor of the pilot plays an irreplaceable role. The pilot's ability to operate and drive, control and judge timing, and respond to random events may lead to completely different trends in the air combat process. Therefore, constructing a "human-in-the-loop" aircraft simulator can be more realistic It simulates real air combat scenarios, and provides strong support for the demonstration of airborne weapons and equipment, the evaluation of combat performance, and the design and optimization of combat operation procedures.

At present, there is no effective simulation and verification platform for airborne weapon combat application deduction, combat mode design, etc. In traditional equipment demonstrations, simple scene settings and simplified model calculations are still widely used, and deductions are carried out under specific combat process scenarios.

The operator is used to complete the construction of the air combat environment in the form of a simulated cockpit operation, and the simulated carrier aircraft is used to complete the air combat confrontation. Simulation of the whole process of air combat can verify the combat concept, combat style and technical scheme of airborne weapons to a certain extent, and improve the overall design capability of the missile.

In the Chinese invention patent with the announcement number CN108254208B, a simulator data generation method for a complete aircraft test bench is disclosed, which can improve the automation degree of the system-level ground test and make the system-level ground test indispensable for The simulator for simulating the state information of the aircraft is automatically controlled; the invention can make the large-scale system test and the flight control test associated with the same ground simulation flight bag, thereby realizing the linkage between the large-system test bench and the flight control test bench; the invention not only can Used in the aviation field, it can also be transformed into the development, maintenance, inspection and other fields of other complex systems, such as aerospace, ships, automobiles, land transporters and other industrial fields with a high degree of automation and easy information collection, and has greater practical applications value.
