A conception of fabricating smart laminate FRP compressor blade has been proposed by the authors. Utilizing the stretching-twisting coupling effect of antisymmetric composite structure, the blade can adjust its stagger angle to the best aerodynamic condition corresponding to the rotation speed and/or working temperature. FEM analysis has been performed to evaluate plate's twist angle under centrifugal and/or temperature load. In this paper, an analytical scheme based on Rayleigh-Ritz method is proposed, by which deformation and stress/strain distribution of angle-ply rectangular plate can be conveniently calculated. Comparisons are made of the analysis results and FEM's, it is seen that present scheme renders good accuracy. Influence of the fiber orientation angle is discussed and the angle at which maximum twist angle appears is found. This scheme provides a fare start for further analysis of plate's nonlinear deformation behavior.
