An air-ground integrated flight test technical framework based on flight simulation

在现代民用运输类飞机的试飞工作中,权衡试飞效率与试飞安全之间的关系,尽可能地压缩试飞周期是试飞从业人员需要不断提升的能力。为了提升试飞监控人员的实时安全评估能力,进而提升试飞效率,提出了一种基于仿真的空地一体化试飞监控技术框架。该技术框架在常规的试飞监控系统基础上,增加了试飞安全评估模型、空地数据同步系统和试飞遥测数据实时处理功能等,总体框架适用于大多数试飞科目,但试飞安全评估模型需根据试飞科目的试飞要求进行仿真需求捕获、场景分析和模型验证等环节。以侧风着陆试飞科目为例,说明了空地一体化试飞技术的基本应用过程,可为空地一体化试飞技术的推广提供参考。

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 subjects,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.
