近几年来,由于航空工业迅速发展,各种新型军用飞机和民用客机不断研制成功和投入生产,对航空钢丝绳的产品质量和品种、规格不断提出了新的要求,尤其是使用在飞机操纵和控制系统的钢丝绳,由于飞机速度的增加,钢丝绳的强度也要求增加;对于长时间用于罗盘针矫正器,其作用对飞机每一个移动进行矫正而产生连续轻微的振动,要求钢丝绳具有一定的可靠安全性能。另外有些部位的钢丝绳由于更换困难,要求有很长的使用期限。对飞行在一万公尺高空的各种喷气式飞机,百分之九十的时间是在零下50℃以下使用的,当飞机通常
In recent years, due to the rapid development of the aviation industry, various new military aircraft and civil passenger aircraft have been successfully developed and put into production. As a result, new requirements are constantly put forward on product quality, varieties and specifications of aviation wire ropes. In particular, they are used in aircraft handling and control System of wire rope, due to the aircraft speed increases, the strength of the wire rope also requires an increase; for a long time for the compass needle appliance, its role in the aircraft every move to correct and produce continuous minor vibration, requiring a certain degree of reliable wire rope performance. In addition, some parts of the rope due to replacement difficulties, require a very long period of use. For all types of jets flying at altitudes of 10,000 meters, 90% of the time is below minus 50 degrees Celsius. When the aircraft normally
