Highlights of aeroacoustics research in the US - 1998

Highlights of aeroacoustics research in the United Slates of America during 1998 are reported in a summary compiled from information provided by membe rs of the Aeroacoustics Technical Committee of the American Institute of Ae ronautics and Astronautics (AIAA) and other leading research groups in indu stry, national laboratories, and academia. The past few years have seen sig nificant progress in aeroacoustics. Research has steadily progressed toward enhanced safety, noise benefits, and lower costs. Since industrial progres s is generally not published in the archival literature, it is particularly important to highlight these accomplishments. This year we chose to report on five topics of great interest to the aerospace industry including a syn opsis of fundamental research, at universities and national laboratories. T he topics chosen are: (1) advanced subsonic technology (AST), (2) high-spee d research (HSR), (3) rotorcraft, (4) weapons bay aeroacoustics control and (5) academic research including computational aeroacoustics (CAA). Althoug h the information presented in this review is not all encompassing, we hope that the topics covered will provide some insights into aeroacoustics acti vity in the U.S. (C) 1999 Academic Press.
