Research on Active Infrared Icing Detection for Helicopter Rotors

针对直升机旋翼结冰的特点,提出了一种主动式红外结冰探测的方法。该方法基于神经网络,通过测量不同冰层厚度的直升机旋翼桨叶结冰表面的红外激光反射系数,达到对直升机旋翼桨叶结冰表面结冰程度分类的目的。实验表明,该方法能够对直升机旋翼桨叶表面的结冰程度进行分类,并能做到准确判断的效果。

For the characteristics of helicopter rotor icing proposed an active infrared ice detection method.The method is based on neural networks,by measuring the thickness of different ice beneath the surface of a helicopter rotor blade icing infrared laser reflection coefficient,reaching a helicopter rotor blades on the ice surface,ice levels in purpose.The experimental results show that the method be able to freeze the surface of a helicopter rotor blades level of classification,and can be accurate to judge results.
