Description

technical field [0001] The invention belongs to the technical field of computer simulation, in particular to a portable ground online flight simulation system. Background technique [0002] In today's world, with the continuous improvement of aircraft autonomy and intelligence, drones are more and more frequently used for battlefield reconnaissance, monitoring and attack tasks, and have gradually become an indispensable and efficient aviation weapon in warfare. In order to save development costs, speed up development, and reduce flight test risks, it is necessary to carry out necessary simulation tests to ensure the safety of UAV flight. [0003] At present, research and development units at home and abroad mainly use semi-physical simulation tests to verify the correctness of airborne software. However, semi-physical simulation tests driven by mathematical models cannot effectively simulate the collaborative work response of UAV avionics, electromechanical, flight control,...

AI Technical Summary

Problems solved by technology

However, semi-physical simulation tests driven by mathematical models cannot effectively simulate the collaborative work response of UAV avionics, electromechanical, flight control, and power systems after cross-linking. Recurrence, the state of the UAV system cannot be fully inspected. For this reason, some research and development units have built an iron bird test bed that is consistent with the real airborne environment to test the state of the UAV system, but the equipment state of the Iron Bird test bed cannot It is always guaranteed to be consistent with the state of the airborne equipment, and the cost of building an iron bird test bed is too high, the economy is not good, the cycle is long, and it is not mobile
