Aero-acoustics

Overview

The University of Mississippi (UM) is committed to advancing cutting-edge research and applying it to solutions for specific problems. One such research field, aero-acoustics, is a growing area that has received renewed emphasis due to advances in air, ground and space transportation.   UM is uniquely positioned with talent, facilities, and innovations to push significant advances in this field including the aero-acoustics Research Program at the National Center for Physical Acoustics.

Partnering with industry and government to push solutions and applications, the National Center for Physical Acoustics was established in 1986 by Congressional Act to specialize in basic and applied research in the area of physical acoustics including aero-acoustics. NCPA partners with industry to design, develop and test advanced aircraft components and sensors for use in the aerospace industry. Specifically, the NCPA aero-acoustics team is looking at noise reduction in aircraft, ways to more efficiently mix fuel, and better designs for cargo and weapons bays.

Aero-acoustics research facilities include:

Tri-Sonic Wind Tunnel Facility:

The NCPA Tri-Sonic Wind Tunnel (NCPA-TSWT) facility was first operated in 2006 and has completed approximately 1000 runs to date.  The facility can support test section Mach numbers from 0.3 to 5.0.  The 12-inch test section has significant optical access to support a variety of non-intrusive measurement methods.

Anechoic Jet Laboratory:

The NCPA Anechoic Jet Laboratory (NCPA-AJL) was purposely built to study the effects of temperature on supersonic jet noise and methods for its suppression.  Room aspiration maintains constant environment temperatures even during continuous operation of nominally 2-inch, Mach 2.0 jets at up to 1500 deg. F.
