摘　　要：轻型直升机在电力巡检和作业中有着广泛的应用,为满足巡检设备在激光扫描和巡线工作中对地理位置信号数据的高精度需求,同时回避直升机主旋翼旋转带来的GNSS信号干扰,有必要在直升机合适位置加装用于巡检设备数据采集的GNSS天线。本文结合改装的适航审定流程,对AS350B3型直升机加装GNSS天线的改装设计进行了分析论证,并在直升机上装机应用,为电力作业直升机改装设计提供相关依据。Light helicopters is widely applied in electric power inspection and operation,in order to meet the high-precision requirements of inspection equipment for geographical location signal data in laser scanning and line patrol work,and avoid GNSS signal interference caused by the rotation of the main rotor of the helicopter,it is necessary to install GNSS antennas for data acquisition of inspection equipment in suitable positions of helicopters.Based on the airworthiness verification process of modification,this paper analyzes and demonstrates the modification design of AS350B3 helicopter equipped with GNSS antenna,which is installed and applied on the helicopter,so as to provide relevant basis for the modification design of electric operation helicopter.
