Project Title:Rotor Unsteady Airloads
Company:Continuum Dynamics, Inc.
Princeton, NJ 08543
Principal Investigator:Bilanin, Alan J.
Over the pase several years, under government and commercial support, Continuum Dynamics,
Inc. has made significant prograss in computing the unsteady wakes of fixed- and
rotary-wing aircraft. This progress, for the most part, resulted from the successful
development of the Basic Curved Vortex Element as a fundamental wake element building
block and a novel generalized vorticity contour representation of the wake. It now
appears that it is possible and practical to compute the convective evolution of
a vortex wake in forward flight and couple this wake to a blade dynamics and aerodynamics
model so that the reliabhle prediction of unsteady rotor blade loading would be possible.
The Phase I research effort would assess the promose of a novel generalized vorticity
contour wake representation to form the basis of an advanced rotor aerodynamics analysis
for forward flight.
