    摘要:

    随着无人机平台的逐渐成熟,近年来无人机广泛应用于航空物探领域。文章设计了一型无人机航磁系统,采用国产铯光泵磁力仪,载机平台为 100kg级汽油动力无人直升机,基于直升机的操作特性研究了不同于固定翼飞机的定点悬停补偿方法。依据《航空磁测技术规范》进行了地面静态噪声测试、磁补偿飞行、动态噪声测试及切割线飞行。结果表明,采用定点悬停的磁补偿方法,系统的磁补偿精度、动态噪声水平及航磁总精度同样能够达到《航空磁测技术规范》要求的一类设备水平,且更易于操作,从而该航磁系统也可应用于大比例尺低飞航磁项目中。

    Abstract:

    With the gradual maturity of UAV platform, UAV was widely used in the field of airborne geophysical explora?tion in recent years. A type of aeromagnetic system of UAV was designed in this paper, which was based on a domestic ce?sium optically pumped cesium magnetometer and a 100 kg gasoline powered unmanned helicopter. Based on the operation?al characteristics of the helicopter, the hover magnetic compensation method which is different from the fixed wing aircraftwas studied. According to the‘Criterion of aeromagnetic survey’, the static noise test, magnetic compensation flight, dy?namic noise test and cutting line flight were carried out. The result shows that, using the fixed-point hovering magneticcompensation method, the magnetic compensation accuracy, dynamic noise level and the total accuracy of aeromagnetic ofthe system can also reach the first level of the kind of equipment required by the‘Criterion of aeromagnetic survey’, and itwas easier to operate. It was proved that the aeromagnetic system could be used in large scale and low aeromagnetic proj?ects.
