The invention belongs to the technical field of structural load measurement in an aircraft flight test, and particularly relates to an aircraft airfoil torque high-precision measurement method. The method comprises the following steps: step 1, arranging a strain sensor on a torque load bearing path of an aircraft airfoil; 2, designing an airfoil torque calibration test condition; 3, connecting one or more combined loading base plates with loading equipment at a lower wing surface loading point in a bonding manner; the pulling/pressing loading of the vertical airfoil is carried out through a hydraulic servo actuator, and a high-precision torque measurement load equation is established.

    本发明属于飞机飞行试验中结构载荷测量技术领域,具体涉及一种飞机翼面扭矩高精度测量方法。方法包括:步骤1:在飞机翼面扭矩载荷承力路径上布置应变传感器;步骤2:设计翼面扭矩校准试验工况;步骤3:在下翼面加载点通过粘接方式将单个或多个组合加载垫板与加载设备连接;通过液压伺服作动器进行垂直翼面的拉/压向加载,建立高精度扭矩测量载荷方程。
