摘　　要：试飞数据作为民机试飞过程中最重要的产物,是表明符合性、验证设计合理性的依据;传统模式下,需要在航后卸载机载记录器中的原始数据,通过4~5小时的预处理时间才能完成试飞数据的工程量转换,耗时耗力,严重影响试飞效率;立足于实际试飞场景,提出了在机载环境下实时进行试飞数据预处理的理念,采用超高速线程并行处理技术,集成了IoTDB时序数据库,设计研制了机载数据在线完全预处理系统;经实验测试,系统实现了国产某大型客机200 Mbps带宽下近80000个试飞数据的实时接收、预处理和数据库存储,将以往的预处理周期压缩至20分钟,支持了高强度、大密度试飞要求。As the most important product in civil aircraft flight test process,flight test data is the basis for showing compliance and verifying the rationality of design.In traditional modes,the original data in the on-board recorder need be unloaded after flight test,and the engineering conversion of flight test data is completed through 4~5 hours of preprocessing,which is time-consuming and labor-intensive,seriously affecting the efficiency of flight test.Based on actual flight test scenario,a real-time flight test data pre-processing concept in the airborne environment is proposed,an ultra-high-speed thread parallel processing technology is used to integrate the Internet of Thing database(IoTDB),and develop an online complete preprocessing system for airborne data.After testing,this system realizes the real-time reception,preprocessing and database storage of nearly 80000 flight test data of a large domestic passenger aircraft with a bandwidth of 200 Mbps,compresses the previous preprocessing cycle to 20 minutes,and supports the requirements of high-intensity and high-density test flights.
