Abstract:
Surface pressure measurements will always be of interest in aerodynamics as they directly relate to aerodynamic forces and allow for a better understanding of the local behavior of the flow. Having a good spatial and temporal resolution is often a technical challenge. This work presents a sensor-embedded sleeve (SES) developed at TU Delft, consisting on a flexible PCB sleeve containing MEMS pressure sensors and microphones. The SES can be installed without any modification to the wind tunnel model and could even be installed in a small aircraft, allowing to capture data in a real flight test. An application of the SES to the study of the interaction between a propeller slipstream and a downstream wing is presented. In addition to unsteady pressure measurements, oil flow visualization was performed to capture the flow development over the wing.
