对民用飞机风标式攻角传感器安装定位进行了研究。根据相关条例中攻角传感器安装使用的要求，提出了侧滑敏感性分析方法和攻角校线分析方法。利用数值模拟方法对传统机头和“流线型机头＋翼身组合体”构型进行气动计算，通过侧滑敏感性分析方法和攻角校线分析方法，对攻角传感器的安装位置规律进行分析，最终在两种机头外形上得到相同的攻角传感器安装定位规律———轴向48％～100％机头最大宽度线上为攻角传感器的最佳安装位置。将得到的规律应用至构型一的攻角传感器安装定位中，并通过风洞试验对安装位置处的侧滑敏感性以及攻角校线进行验证，结果表明侧滑敏感性和攻角校线试验结果与 CFD 计算结果完全一致，证明了本文提出的攻角传感器安装定位分析方法合理、可行，总结的规律正确，对机头外形类似飞机的攻角传感器安装定位具有一定的参考价值。

Angle of attack(AOA)sensor orientation for civil aircraft has been researched in this paper.According to the requirements of AOA sensor orientation in Chinese aviation industry standard HB regulations,the sideslip sensitive analysis method and AOA calibrating analysis method have been developed.Air flow fields have been calculated with the conventional nose configura-tion and streamline nose configuration by numerical simulation,and the sideslip sensitive analysis and AOA calibrating analysis have been used to obtain the most proper location to install the AOA sensor.An identical AOA sensor installing rule has been obtained with two different nose configurations i.e.the optimized position of AOA sensor is in the nose maximum half-breadth range of 48%-100% in stream-wise direction.The installing rule has been applied to the conven-tional nose configuration.Moreover,a validated wind tunnel test has been conducted.The test results of sideslip sensitivity and AOA calibration showed significant agreement with CFD re-sults,which implying the analysis methods and relevant AOA sensor installing rule are applica-ble.Furthermore,the obtained method and rule have the potential to be utilized on any other air-crafts with similar nose configuration.
