“…Madoka Nakajima developed a FBG pressure sensor shown in Fig. 1, which transits the out vertical pressure by a spacer to the horizontal strain of FBG sensor, the calibration results show that there was good linear relationship between the out pressure and the FBG wavelength shift [6] . But in his study, there is no theoretical relationship between the pressure and the horizontal strain of the FBG.…”

The measurement of pressure is essential for the design and flying controlling of aircraft. In order to measure the surface pressures of the aircraft, the common pressure tube method and Pressure sensitive paint measurement method have their own disadvantages, and are not applicable to all aircraft structures and real time pressure monitoring. In this paper, a novel thin film pressure sensor based on Fiber Bragg Grating (FBG) is proposed, using FBG measuring the tangential strain of the disk sensing film. Theoretical circle strain of the disk sensing film of the pressure sensor under pressure and temperature variation are analyzed, and the linear relationship between FBG center wavelength shift and pressure, temperature variation is gotten. The pressure and temperature calibration experiments prove the theoretical analysis. But the calibration sensing parameters are small than the calculating ones, which is caused by the constraint of optical fibre to the thin sensing film.
