In flow control system

pressure sensor is embedded in wing in material made of composite fiber of which the structure will affect performance of the pressure sensor. The stress situation of the embedded pressure sensor can be simulated with the help of finite-element-analysis software. The result is

that the stress concentration appears at the edge of the pressure sensor. By improving the design of sensor

the stress concentration can be reduced or eliminated. The improving methods include the chamfer of 4 right-angle corners of sensor

rotation of45° before embedding

and a peripheral bonding with an aluminum foil. As a result of the finite-element-analysis simulation of these three improving methods

the bonding with aluminum foil effectively improves the tensile strength of the sensor and eliminates the stress concentration.
