气压高度误差对适航标准的符合性方法研究
|
摘要
运输类飞机适航标准规定了气压高度误差的可接受范围,按照条款要求,表明符合性时需要将试验高度处的气压高度误差向海平面进行换算。相比ERJ、ARJ在适航审定试飞时采用的等静压误差处理方法,本文从是否考虑压缩性的角度出发,建立了适用性更高的气压高度误差转换方法,并通过某型飞机试飞结果分析进行了验证与说明。
The airworthiness standard for transport aircraft specifies the acceptable range of barometric altitude error.According to the terms and conditions, it is necessary to convert barometric altitude error at the test height to sea level when demonstrating its compliance to CCAR. Compared with the ERJ and ARJ's isostatic pressure error processing method used in airworthiness certification test flight, this paper establishes a more applicable barometric altitude error conversion method from the perspective of considering the compressibility, and the test flight results of a certain aircraft are analyzed and verified.
