摘　　要：阐述了长叶片扭转恢复对叶片几何、气动、强度和振动产生的影响，并根据长叶片的扭转恢复原理，采用叶片予扭和予扭装配的方法来解决或缓解扭转恢复所带来的负面影响，建立一种新的长叶片设计体系─—长叶片约束予扭设计体系。In this paper,the influence to geometry,aerodynamics,strength and vibration by twist-back of long blade have been elaborated.And according to twist - back principle of long blades,by using pre-twisting bladeand fit together,the bad influence has been solved or reduced.An new design system of long blade,the designsystem of long blade by restrained pre-twisting,has been establised.
