摘要: 由于高海拔山区的特殊性,在高海拔山区开展航空地球物理勘探需要满足飞机的性能要求.通过分析高海拔山区地理环境、气候的特殊性及航空地球物理勘探飞行的特点,从高海拔机场起降能力、飞机减载后商载能力、爬升率、低空性能及升限等方面,提出了在高海拔山区开展大范围航空地球物理勘探的飞机选型原则.对比分析了空中国王350ER、塞斯纳550奖状Ⅱ等飞机的主要性能,特别分析了空中国王350ER在西藏东部地区的航磁调查实际飞行性能.分析结果显示,空中国王350ER的实际飞行性满足高海拔山区航空地球物理勘探的要求.Abstract: Aircraft landing and flying in super-high plateau area has its special characteristics.Based on the analysis of the characteristics of the geographical environment,climate and the airborne geophysical exploration in the super-high plateau area,the authors put forward the principle of aircraft type selection.The main performance of King Air 350ER aircraft and that of other aircrafts were comparatively studied.The flight performance of King Air 350ER in the eastern region of Tibet was analyzed.The results show that the King Air 350ER meets the requirements of airborne geophysical exploration in super-high plateau area.
