摘      要：Morphing leading edge has great potential for noise abatement and aerodynamic efficiency *** drooping effect is realized by bending of the flexible skin which encloses to form the leading *** the flexible skin is often made of composite laminates of Glass Fiber Reinforced Plastics(GFRP),the lay-up sequences have become the determinant,which affects not only the morphing quality but also the manufacturing *** optimizing methods of layup sequences are comparatively *** the first method,the laminal quantities in 0
,±45
and 90
vary independently,while in the second one,the concept of isotropic laminate unit[0/45/
45/90]s is employed and the unit quantity is the unique *** evaluation demonstrates that for both methods there is insignificant impact to the overall morphing quality;however,specific concern is equally necessary for these two methods to the tip of the leading edge where the skin is at its minimum thickness and bears the most severe bending *** terms of computational efficiency and post-processing labor,the second method has better performance.
