The invention is applicable to the technical field of aircraft icing detection, and provides an improved icing sensor mounting position determination method. The method comprises the following steps: calculating an air flow field of an aircraft with a sensor; calculating the ratio beta1/beta2 of the water collection coefficient beta1 of the position where the sensor is located to the maximum water collection coefficient beta2 of the wing; if the ratio beta 1/beta 2 is greater than 1, calculating the ratio h1/h2 of the average icing thickness h1 on the sensor to the average icing thickness h2 on the windward side of the wing; if the ratio h1/h2 is greater than 1, determining the position as the installation position of the sensor; if the ratio h1/h2 is less than or equal to 1, determining that the position is not suitable for installing the sensor. According to the method, ice type calculation and liquid water analysis are coupled to judge the mounting position of the sensor, so evaluation errors caused by low freezing rate are avoided, and the evaluation reliability is higher.

    本发明适用于飞机结冰探测技术领域,提供了一种改进的结冰传感器安装位置确定方法:计算带有传感器的飞机的空气流场;计算传感器所在位置的水收集系数β1与机翼上的最大水收集系数β2的比值β1/β2;若比值β1/β2大于1,则计算传感器上的平均结冰厚度h1与机翼上迎风面的平均结冰厚度h2的比值h1/h2;若比值h1/h2大于1,则将该位置确定为传感器的安装位置;若比值h1/h2小于等于1,则该位置不适合安装传感器。本发明将冰型计算与液态水分析进行耦合用于判断传感器的安装位置,避免了由于冻结率较低而导致的评估误差,评估可靠性更高。
