The invention is suitable for the technical field of wind tunnel tests, and provides an anti-icing and deicing test temperature control method and system. The method comprises the following steps: operating a wind tunnel to a stable state, starting an anti-icing and deicing test system, wherein the anti-icing and deicing test system comprises a test model and a heating area arranged on the surface of the test model in the extending direction of the front edge, and the heating area is provided with a plurality of temperature measuring elements in the extending direction of the front edge; and when an actual temperature fluctuation quantity is greater than a target temperature fluctuation quantity, reducing the voltage value of a power supply, wherein the actual temperature fluctuation quantity is the absolute value of the difference value between the actual temperature value and the target temperature value, and the actual temperature value is the average value of the actual temperature values of the plurality of temperature measuring elements in the same heating area within the preset time length. The anti-icing and deicing test temperature control method and system provided by the invention have the advantages of high reliability, high accuracy, low loss and long service life of equipment.

    本发明适用于风洞试验技术领域,提供了一种防除冰试验温度控制方法和系统,防除冰试验温度控制方法包括如下步骤:运行风洞至稳定状态,开启防除冰试验系统,防除冰试验系统包括试验模型和试验模型表面沿前缘沿伸方向设置的加热区,加热区沿前缘沿伸方向设置有多个测温元件;当实际温度波动量大于目标温度波动量时,降低电源的电压值;实际温度波动量为实际温度值与目标温度值的差值的绝对值,实际温度值为同一加热区上多个测温元件的实际温度值在预定时长内的平均值。本发明提供的一种防除冰试验温度控制方法和系统具有高可靠性、高精确度、低损耗和设备寿命长的优势。
