Corrected frequency-dependent directivity indices for large solid rocket motors

Grant W. Hart, Kent L. Gee et al.

in Proceedings of Meetings on Acoustics

For many years, empirical models for rocket noise radiation relied on the directivity indices published in NASA SP-8072 (K. Eldred, 1971). Because these were known to have inaccuracies, NASA led a ...

Effect of streamwise vane treatments on the noise reduction performance of trailing edge serrations under aerodynamic loading conditions

Shivam Sundeep, Peng Zhou et al.

in The Journal of the Acoustical Society of America

Trailing edge serrations have shown remarkable ability to reduce noise, but their effectiveness can be significantly impacted by flow misalignment, particularly under aerodynamic loading conditions. ...
