Congratulations to IMG undergraduate student Alexander Reilly on winning 1st place in the undergraduate category at the AIAA Region II Student Conference hosted on April 4-5, 2022 at the Georgia Institute of Technology! Alexander gave a presentation titled, "Development and Fabrication of an Ultrasonic MEMS Anemometer for Use in Low-Pressure Environments". Great job Alexander!
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
Austin Vera will defend his proposal titled: "A Flat-Packaged MEMS-Based Optical Pressure Sensor for Harsh Environments" on Friday, October 8th at 9:00 AM.

Understanding the character and dynamics of hypersonic boundary layers poses a considerable challenge to the design of hypersonic vehicles. Specifically, being able to predict the location of laminar-to-turbulent transition is of critical concern as it affects heating rates, aerodynamic loading, and skin-friction drag, therefore impacting the design of the thermal protection system and thus the overall weight and performance of the vehicle.
