Abstract
Purpose
This paper aims to develop a new approach for aeroelastic analysis of hingeless rotor blades.
Design/methodology/approach
The aeroelastic approach developed here is based on the geometrically exact fully intrinsic beam equations and three-dimensional unsteady aerodynamics.
Findings
The developed approach is accurate, fast and very useful in rotorcraft aeroelastic analysis.
Originality/value
This beam formulation has been never combined with three-dimensional aerodynamic model to be used for aeroelastic analysis of blades. In addition, it is possible to handle the composite blades, as well as blades with initial curvatures and twist with this proposed formulation.
