Ben Sim

United States of America

 

1969 - 2018

In 2004, Sim took a senior research engineer position on a University Affiliated Research Center (UARC) contract working with the US Army Aero flight dynamics Directorate (now Aviation Development Directorate) at NASA Ames Research Center from 2004 to 2010. He became a US citizen and was hired as an Army Research Scientist in 2010. Sim was promoted to acoustics subject matter expert in 2013.

Sim published 7 peer-reviewed journal papers and 45 conference papers, five of which were selected as “Best in Session” at AHS Forums. He had an outstanding career as a researcher conducting independent analysis, and as a team member working on numerous analysis, wind tunnel and flight test projects. Sim published key papers on the effect of active rotors on helicopter source noise. He also published fundamental acoustics research (analytical and experimental work) on the effects of altitude, terrain and helicopter maneuvering flight on radiated noise. Recently, he had expanded his work to study source noise for various advanced rotorcraft configurations.

Sim was a strong supporter of the Vertical Flight Society, serving as a session chair, participating in the Acoustics Technical Committee and reviewing papers for the AHS Journal, since joining the Society in 1990.
