航空放射性测量中的一项重要工作——飞机改装

AN IMPORTANT WORK IN AIRBORNE RADIOMETRIC SURVEY——THE MODIFICATION OF AIRCRAFT

为了发挥航测仪器的性能和提高测量精度,用于航空放射性测量的飞机必须进行必要的改装,改装工作除了保证航测仪器安装可靠、牢固之外,还要使飞机对仪器的磁干扰,放射性干扰和电干扰降低到允许的水平。本文对运五和运十二飞机存在的干扰情况进行了讨论,并就如何消除这些干扰提出了切合实际的改装方案。

In order to give play to the performance of airborne instruments and raise the survey accuracy, the aircraft used in the airborne radiometric survey must be modified. Besides the instruments on board reliable and firm, the modification of the aircraft should make magnetic radiometric and eleetric interferences on the instruments decreased to the permitted level. This paper discusses the interferences occurred within the aircrafts Y5 and Y12 and also presents the suitable and practical modification details to eliminate these interferences.
