Considering the effect of the variation of the unbalance laminates of skins on the aeroelastic performance,aeroelastic models were built for the high-aspect-ratio composite wings with different swept angles and unbalance laminates in the skins.

With a turbine stationary cascade serving as a prototype cascade and through a change of axially-swept angles and heights of the prototype to form blades with various swept blade profiles,the influence of axially-swept blades on the aerodynamic performance of the turbine stationary cascade was studied.
