摘要
针对国际适航认证(FAR25)及300m垂直间距空中交通管制(RVSM)等对大气系统校准提出的高精度参考基准要求,提出了直观的标准空速管法,通过对初步试验结果的分析,发现了直接校准的缺陷和偏差根源。提出了"飞行检定"观点,改进了校准原理、观测模型和数据处理方法,建立了基准空速管法。实际飞行试验及误差分析讨论,表明该方法可满足相关领域的严格要求。
Aiming at the accurate reference source that required by FAR25 and RVSM et al on air data system calibration, the intuitive standard-air-data-boom method was proposed. By analy- zing the primary test results about the method, the deficiency and deviation source were found. The ＂flight verification＂ idea was introduced. Calibration principle, observation model and data solution process were improved, and the reference-air-data-boom method was founded. Flight test and error analyses showed that the method can satisfy the strict requirements from correlative domain.
