The San Francisco Bay Area Chapter of the AHS International will sponsor a
conference on rotorcraft aeromechanics, 21-23 January 2004. The conference will
start with a morning session of invited papers on aeromechanics in new
rotorcraft development programs. This will be followed by five half-day segments
of two concurrent technical sessions covering the disciplines of Aerodynamics,
Dynamics, Acoustics, Handling Qualities and Test & Evaluation.
