1. comprise a wind turbine blade for the cowling with aerodynamic profile, described cowling comprises:

  • Rigid structure members, described rigid structure members forms most of aerodynamic profile;

    WithThe trailing edge parts of non-active controlled, elastically deformable, described trailing edge parts are arranged on to make aerodynamic profile become complete on structure member,Wherein, described trailing edge parts are formed by the material of Young'"'"'s modulus in 0.5GPa to 2.5GPa scope, make when the load on trailing edge parts exceedes predetermined threshold, and described trailing edge parts incite somebody to action flexibly fold, andWherein, described structure member comprises the unidirectional enhancement layer adjoining described trailing edge parts, and described unidirectional enhancement layer is included at least one deck unidirectional fibre opened up substantially and extend to direction.
