Dynamic flight load measurements with MEMS pressure sensors

Abstract The determination of structural loads plays an important role in the certification process new aircraft. Strain gauges are usually used to measure and monitor encountered during flight test program. However, a time-consuming wiring calibration is required determine forces moments from measured strains. Sensors based on MEMS provide alternative way aerodynamic pressure distribution around component. Flight tests were performed with research glider aircraft investigate determined strain measurement technology. A wing glove equipped 64 sensors was developed for measuring selected section. shear force both load methods compared each other. Several maneuvers varying This paper concentrates evaluation dynamic including Stalls Pull-Up Push-Over maneuvers. effects changes flow characteristics maneuver could be detected directly MEMS.
