结冰速率传感器是保证飞机在结冰气象条件下安全飞行的重要部件。基于红外光谱吸收的结冰速率传感器较其他型式的精度更高。对红外结冰速率传感器进行研究,推导了双波长对比吸收测量冰厚的理论模型。设计了一种采用对光源驱动电路进行脉冲调制驱动双光源的红外结冰速率传感器。提出了其关键技术并给出了解决方案。研究内容为红外结冰速率传感器的实际应用提供了参考依据。
The icing rate sensor is an important part of ensuring that the aircraft can fly safely under icy weather conditions. Icing rate sensors based on IR absorption are more accurate than other types of sensors. Infrared icing rate sensor was studied and the theoretical model of dual-wavelength contrast absorption ice thickness measurement was derived. A kind of infrared icing speed sensor which uses pulse modulation to drive the light source to drive the double light source is designed. Proposed its key technology and gave the solution. The research content provides a reference for the practical application of infrared icing rate sensor.
