Jonathan Brown ’19, BSME, presented his paper at the 25th AIAA/CEAS Aeroacoustics Conference in Delft, Netherlands on May 20.
The paper, titled “Acoustic Radiation of Supersonic Inlet with Auxiliary Door and Mean Flow,” was authored with Paul Slaboch, Assistant Professor of Mechanical Engineering. This was a companion paper to another written in collaboration with NASA Glenn Research Center engineers titled “Supersonic Engine Inlet Tone Noise Radiation.” The project is studying the noise radiated from a spike inlet that is designed for a supersonic commercial transport aircraft. While the sonic boom is generally the loudest portion of the flight, this only occurs at supersonic speeds during cruise. The aircraft must also be quiet during takeoff and approach, and this is when the noise coming out of the inlet is important. This work was funded by the NASA Commercial Supersonics Technology program and the NASA CT Space Grant Consortium. Jonathan, a recent graduate of University of Hartford, will begin working for Pratt & Whitney with the Acoustics group this summer.

Slaboch was recently awarded a research contract with NASA through the USRA (Universities Space Research Association). The contract will allow him and undergraduate student Aikaterini Stylianides ’20, BSME with Acoustics concentration, to continue the work that he was doing with Jonathan. The total amount of the contract is $45,331 and includes travel to Cleveland to visit NASA Glenn Research Center to present our work at the end of July.
The College of Engineering, Technology, and Architecture (CETA) would like to congratulate Jonathan Brown and Paul Slaboch on their research efforts. CETA is proud of the continued NASA collaborations year after year and the opportunity to involve more undergraduate students with this kind of research.
