Abstract
A film-type pressure sensor was developed based on the Fiber Bragg Grating (FBG) technology. FGB is commonly used in optical communications and is applied to stress/strain measurement recently. One of the merits of this sensor is the easiness to use, and time-varying pressures at multi-points can be measured. Wind tunnel tests were conducted and the pressures of 4 points on the wing model surface were measured. Obtained data were compared with the CFD simulation results and the results of another experiment, and the utility of the sensor was discussed.
