摘　　要：中高山地区作业的航空地球物理勘探飞行器需要有高原适航性。通过对比空中国王350ER在起降条件、最大升限、最大续航能力及高原机动能力等特点,提出了在中高山地区的低高度、大比例尺的航空地球物理勘探飞行器的选型原则及飞行方法。通过甘肃某测区的实际测量飞行验证了该原则和方法的可行性。分析结果显示,AS350B3型直升机在中高山地区作业时表现出的实际飞行性能满足在该类型区域低高度、大比例尺的航空地球物理勘探的要求。The airborne geophysical exploration flying vessel which performs operation in middle and high mountain areas needs plateau adaptability.Through a comparative study of the characteristics of AS350B3 helicopter in such aspects as its taking off condition, maxi- mum flying altitude, maximum endurance and plateau flexibility, the authors put forward the type-choosing principle and flying method of the airborne geophysical exploration flying vessel for low altitude and large scale survey.The practical surveying flying in a certain sur- veying area of Gansu Province has proved the feasibility of the principle and method put forward by the authors.Analysis shows that AS350B3 helicopter can meet the requirement of airborne geophysical exploration in such areas.
