PhD candidate Aaron Defreitas is leading a test in the Virginia Tech Stability Wind Tunnel investigating data analysis methods for large diverse sensor systems. His analysis procedures are being used to identify anomalous results in real-time while collecting high volume data. The figure below shows the automated detection of a bad pressure port in a total pressure rake measuring the wake profile downstream of an airfoil. This port is seen in the profile at -10 degrees AoA. This is an obvious error, but the method is proving useful in detecting very small anomalies as well. These methods should improve identification of smaller errors that may be overlooked by a user trying to manage the collection of high volume data manually.

Just completed the first wind tunnel experiment for our new turbulence ingestion noise project. We tested the body of revolution designed collaboratively by researchers at the University of Notre Dame, Florida Atlantic University, and Virginia Tech. This body will produce a thick turbulent wake to be ingested by our rotor. 

Members of CREATe at Virginia Tech presented at the NAWEA Symposium at Iowa State University. We had a great time and many interesting discussions. We would like to thank our hosts Profs. Hui Hu, Simon Laflamme, and Anupam Sharma.
