Abstract

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.

Key words： optical fiber sensing; operation loads; flap actuator; flight test; loads identify
