Boyd, David Douglas Jr.2014-03-142014-03-141999-07-27etd-080999-163154http://hdl.handle.net/10919/28591A new unsteady rotor/fuselage interactional aerodynamics model has been developed. This model loosely couples a Generalized Dynamic Wake Theory (GDWT) to a Navier-Stokes solution procedure. This coupling is achieved using a newly developed unsteady pressure jump boundary condition in the Navier-Stokes model. The new unsteady pressure jump boundary condition models each rotor blade as a moving pressure jump which travels around the rotor azimuth =and is applied between two adjacent planes in a cylindrical, non-rotating grid. Comparisons are made between predictions using this new model and experiments for an isolated rotor and for a coupled rotor/fuselage configuration.In CopyrightComputational fluid dynamicsRotorcraftAerodynamicsUnsteady FlowDissertationhttp://scholar.lib.vt.edu/theses/available/etd-080999-163154/
