Description

Technical Field

[0001] This application belongs to the field of airborne testing technology, and specifically relates to an aircraft braking data processing system. Background Technology

[0002] Aircraft braking systems are highly complex and critical electromechanical systems that directly impact flight safety. After the braking control system is designed and manufactured, it requires integrated testing and flight testing before it can be put into service. Processing and analyzing the test data clarifies the performance compliance of the aircraft braking system and identifies areas for optimization. Analyzing the data from integrated testing verifies the static performance of the braking system; analyzing the data from flight testing allows for the improvement of the airborne software of the braking control system, thereby optimizing the ergonomics and enhancing its anti-skid efficiency.

[0003] Aircraft braking systems generate a large amount of test and flight data during testing and flight trials. Current technology only allows data analysis using two conventional software programs: UltraEdit and Excel. The main problems are: First, inconsistent data storage formats require designers to adjust the data format, leading to a huge and tedious workload of repetitive tasks as test data accumulates. Second, the braking system is used for very short periods during flight tests, only before takeoff and after landing. Before data analysis, the operating time of the braking system must be selected, which is prone to errors and frequent rework in conventional software. Third, the deceleration effect of the braking system during flight tests is highly correlated with other aircraft systems, requiring comprehensive analysis of multiple parameters from multiple systems. Curves drawn using conventional software have poor parameter recognition capabilities. Summary of the Invention
