航空物探测量中直升机起降点设置及应用

在航空物探测量飞行中,直升机以其机动灵活、出色的超低空性能以及能够沿强起伏地形飞行等特点,获得了业界认可的测量效果。但是直升机续航能力不足的弱点也成为野外飞行作业的首要问题,在测区内设置临时起降点这一方法可以很好地解决直升机续航能力不足的难题。笔者在总结直升机临时起降点设置原则基础上,利用实例说明直升机临时起降点设置方法及直升机飞行测量效率。该方法提高了野外飞行作业的效率,扩大了飞机的测量活动范围,降低了飞行作业的成本。

Setup and application of the helicopter taking off and landing point in airborne geophysical survey

In the airborne geophysical survey,the survey results acquired by the helicopter are recognized in geological industry because of the advantages of mobility, hedgehopping and contour flying. But the poor endurance of the helicopter is the primary problem during the airborne geophysical survey. Establishing a temporary taking off and landing point for the helicopter is the best way to solve this problem. After Summarizing the setup principles of the temporary taking off and landing point of the helicopter, the authors explained the methods of setting up the temporary taking off and landing point and the survey efficiency of the helicopter through a concrete example. The method has highly promoted the flying efficiency, expanded the survey range and reduced the survey cost.
