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。 Aimed at the characteristics of helicopter rotor icing, an active infrared icing detection method is proposed. The method is based on neural network to measure the degree of icing of helicopter rotor blade icing surface by measuring infrared laser reflection coefficient of helicopter rotor icing blade icing surface with different thickness of ice layer. Experiments show that this method can classify the degree of icing on helicopter rotor blades and can accurately determine the effect.
