Abstract

The current study is an extension of an earlier work on nonlinear flexible multibody dynamic formulation for rotorcraft analysis that was limited to the development of a robust flexible multibody dynamic tool without taking into account the effect of the aerodynamic loading. As a preliminary attempt to develop a coupled three-dimensional CSD/CFD analysis tool for rotorcraft analysis, the current study deals with the coupling of the existing structural analysis with a quasi-steady aerodynamic analysis based on lifting line theory. As opposed to the conventional approach of using beam elements to represent the rotor blade, the current analysis utilizes a shell element, which assumes non-linear strain measure and rotation, as well as transverse shear deformation. The ease of modeling various types of rotor configuration while relaxing some of the restrictions has been discussed.
