基于Z-5B型无人直升机的航空物探(磁/放)测量技术研究及应用
Study and application on aviation geophysical(magnetic/radioactive)measurement technology based on Z-5B unmanned helicopter
摘要
Abstract
In recent years,unmanned aerial vehicle(UAV)geophysical exploration has been widely applied and played an important role in the exploration of uranium resources,metallic and non-metallic mineral resources,and other fields in China.In order to enhance the automated operation capability of aerial geophysical exploration and reduce safety risks,study on aerial geophysical(magnetic/release)measurement technology based on Z-5B unmanned helicopter has been carried out.Key technologies such as integrated modification of UAV magnetic/release measurement system,flight operation along terrain undulations,UAV magnetic compensation,and calibration of UAV magnetic/release system have been overcome.Areal measurement test flights were carried out in the northern region of Songliao basin,and various technical indicators met the regulatory requirements.The test results showed that the system has good detection ability at a speed of 54 km·h-1 and a flight altitude of 100 meters,which can clearly identify the distribution of surface radioactive fields and magnetic field characteristics,delineate abnormal ranges,and has the ability to simulate ground flight under gently undulating terrain conditions.Therefore,the UAV magnetic/release measurement system can meet the current needs of small-scale measurement and has production operation capabilities.关键词
