一种基于飞行仿真的空地一体化试飞技术框架

In the modern civil transport aircraft flight test, flight test practitioners need to constantly improve the ability and reduce flight test cycle as much as possible, considering the relationship between flight test efficiency and flight test safety. In order to improve the real⁃time safety assessment ability of flight test monitoring personnel and reduce the increased test tasks due to safety considerations, a technical framework of air⁃ground integrated flight test according to the simulation results was proposed. Based on the conventional flight test monitoring system, the technical framework adds the flight test safety assessment model, air⁃ground data synchronization system and flight test telemetry data real⁃time processing functions. The overall framework is suitable for most flight test sub⁃ jects, but the flight test safety assessment models need to carry out simulation requirements capture, scene analysis and model verification according to the flight test subjects requirements. Finally, taking crosswind landing flight test as an example, the basic application of air⁃ground integrated flight test technology is illustrated, which can provide reference for promoting the air⁃ground integrated flight test technology.
