摘要
为了研究民用飞机减速板打开引起的襟翼载荷增量,验证襟翼中小偏度下的严重操纵载荷准确性,避免成本高昂的特殊构型试验件研制和减少机上管线敷设空间限制等问题,针对某具体型号襟翼运动机构,建立了基于光纤传感的操纵载荷测量系统、测量系统校准方法,完成襟翼作动器操纵载荷和翼面总载荷的直接验证与确认。试飞实施结果表明,基于光纤传感的襟翼操纵载荷识别及测试技术在某型号减速板打开后襟翼操纵载荷试飞中的研究应用,为襟翼操纵载荷验证提供了一种有效的高精度、低成本试飞测试方法。
In order to investigate the flap load increment caused by brakes extension for civil transport,verify the accuracy of the critical operation load for flap with small and medium deflection,avoid the development of additional special configuration test pieces and reduce the space limitation of the pipeline laying on the aircraft,aiming at a specific type of flap mechanism,a flap operation load measurement system based on optical fiber sensor and the calibration method of the measurement system are established.The method is used to directly verify and confirm the operation load of the flap actuator and the total load of the flap panel.The results of flight test show that the technology of flap control load identification and test technic based on optical fiber sensor is applied in the study of flap control load with brakes opening effect on a certain transport,which provides an effective high-precision and low-cost flight test method for flap control load verification.
