2021 AIAA Sensor Systems and Information Fusion Best Paper Award!

11/29/2021

 
Our group won the AIAA 2021 SciTech Forum Best Paper Award awarded by the Sensor Systems and Information Fusion Technical Committee. The winning paper was “A Bayesian Mixture Model Approach to Anomaly Detection with Application to Wind Tunnel Experiments” and the lead author was Sierra Merkes. arc.aiaa.org/doi/abs/10.2514/6.2021-1268

Congratulations Dr. Aaron Defreitas!

Preparing for a propeller noise experiment in the Virginia Tech 30" Anechoic Wind Tunnel
Our new 30" wind tunnel is running! This tunnel will expand our current capabilities as well as provide a facility for experiments that don't require the capability of our larger Stability Wind Tunnel. In addition, the test section of this facility is convertible from an open-jet facility to a closed Kevlar-wall test section. The test section is designed to be fully anechoic down to 400 Hz. Currently, the facility is being calibrated and its performance assessed while preparing for its first experiments of propeller noise!

Congratulations to Dr. Christopher Hickling!

Christopher successfully defended his dissertation "Inhomogeneous, Anisotropic Turbulence Ingestion Noise in Two Open Rotor Configurations" and will begin his new position at NSWCCD this November. Congrats, Christopher!

Cough Analysis Work Featured on NPR

9/7/2020

 
Robbie Harris's interview with my colleague Dr. Shane Ross is available at the following link. They discuss our new project sponsored by the Virginia Tech COVID-19 Rapid Response Seed Fund which is focused on using machine learning to identify and count coughs in public spaces. We hope this information can be used as an early detection tool to inform local officials about potential outbreaks. Stay safe everyone.

Congratulations to Stefan Letica on his successful MS defense! His thesis topic was focused on trailing edge noise reduction. His thesis should be available on the Virginia Tech ETD website soon. It is titled "Understanding the Impact of a Serrated Trailing Edge on the Unsteady Hydrodynamic Field". Great work, Stefan!

25th AIAA/CEAS Aeroacoustics Conference

6/4/2019

 
Just returned from the annual aeroacoustics conference in Delft, Netherlands. My student, Christopher Hickling, did a great job presenting his work concerning turbulence ingestion noise, and our work on drone noise received a lot of attention. VT was well represented at the conference. Congratulations to Dr. William Devenport for winning the AIAA Aeroacoustics Award and Kyle Daniel for winning Best Student Paper.

Another Successful Wind Tunnel Test

6/8/2018

 
​Our graduate students have completed another successful wind tunnel test. This is the first test in a series considering the response of a rotor to transient and stochastic disturbances in the wake of a body of revolution.
