Assessment of composite rotor blade modeling techniques

摘要

In the present paper, an assessment is made of the state-of-the-art in modeling composite rotors with a view of bringing out the influence of special characteristics of composite materials. The review encompasses the modeling on thin-and thick-walled composite rotors, the influence of non-classical effect such as out-of-plane warping, warping restraints, and transverse shear, non-uniformities in blade construction, large deformation, aeroelastic stability in hover and in forward flight, aeromechani- cal stability and optimization. The paper includes recommendations for future directions in these topics.
