Aerospace Acoustics
Objectives
- Develop advanced acoustic damping treatments
- Develop active noise control approaches
- Develop advanced sensing approaches
WHY IT MATTERS
- Next generation aircraft have more stringent limits on radiated noise
- A high percentage of failures in launch vehicles is due to sonic excitation at launch
Recent Accomplishments
- Acoustic meta materials have been tested and shown to have significantly increased sound absorption
- Improved acoustic beamforming techniques for wind tunnels have been demonstrated
- A piezoelectric line distributed strain sensor for piping systems has been developed and demonstrated
