Abstract
AVID proposes the development of a lifting surface method for rotor aerodynamic analysis. The method will use a cambered mean-surface analysis for the blades, using doublet lattices to define the geometry, with vortices shed by all aerodynamic surfaces. The focus of AVID's approach is modifying and extending an existing AVID unsteady doublet lattice method, developed for flapping wing applications, to analyze rotors. It will also be coupled with a parametric geometry modeler that be used to rapidly generate complex geometries and facilitate lattice creation. The method will provide lift, drag, and pitching moment distributions along the blade, and provide information suitable for integration with other discipline codes and rotorcraft comprehensive codes. In addition, a Phase I Option is proposed that provides validation for the analysis, code speed optimization, and continued methodology development. The optional work identified here will provide a smooth transition to the increased fidelity required for future Phase II work.
