民用飞机迎角传感器布局气动分析

Aerodynamic analysis of AOA sensor location design on civil aircraft

  • 摘要: 民用飞机迎角传感器布局设计的首要目标是使得迎角信号具有高鲁棒性及高信噪比的品质。在迎角传感器布局设计中,迎角信号的高鲁棒性体现为迎角校线不受侧滑角因素影响,高信噪比体现为迎角校线受机身迎角因素影响明显。本文通过CFD方法研究了迎角传感器布局在某民机机身不同位置时迎角校线随机身迎角及侧滑角的变化规律;获得了迎角校线随侧滑角变化不敏感的机身区域,及迎角校线随机身迎角变化敏感的机身区域,即在机身最大半宽线附近。该研究可为迎角传感器的布局设计提供参考。

     

    Abstract: To achieve AOA (Angle of Attack) signal with high robust and high SNR (Signal-to-Noise Ratio) is the first principle of AOA sensor location design. Insensitivity of AOA correction curve with AOS (Angle of Side Slip) means high robust AOA signal. Sensitivity of AOA correction curve with AOA means high SNR AOA signal. A comprehensive CFD study is consequently carried out to investigate the local AOA dependencies on body AOA and AOS for a typical civil aircraft. A region on which local AOA is insensitivity to AOS and sensitive to AOA is discovered on the fuselage by some statistic post-processing of the CFD results. This region is then identified as a baseline for locating the AOA sensor.
