A Flat-Packaged Optical Shear Stress Sensor Using Moiré Transduction for Harsh Environments
As the field of hypersonic vehicle design develops, having shear stress data can aid in the minimization of
drag source effects and verify results from computational fluid dynamics simulations. Transducer size,
placement, and narrow bandwidth currently limit accurate shear stress measurements due to the small
length and time scales seen in turbulent fluid motion and the issue of flow disruption. Shock wave and
boundary layer effects also produce large thermal loads in hypersonic flows. The proposed research plan
