The virtual mass method is used to research on the fan blade characteristic.

It was proved that the algorithm was stable and exact,and it could solve many problems of fan blade production.

According to the shape character of one fan blade, the forming steps was designed and the shape of related blank was modeled.

The air-blower vane made with the above materials conform to the standard MT 113-85 and practical demand.

The problem of designing air-blower vanes is studied by using Riemannian geometry.

Through mixing melt technology, the effects of defferent fire resistance and antistativitv materials to the properties of fire resistance and antistativity were studied; The air-blower vane used in the material conform to the standard MT 113-85 and practical deman

Finite element ultimate analysis and design of composite wind turbine blade based on non-linear constitutive relationship;

The current development of the wind power-generation and the technology of wind turbine blade at home and aboard is briefly introduced,then the composites,structural design,airfoil,and molding of the technology is also elaborated.

With finite element software ANSYS,this paper describes in detail the process of finite element modeling of large-scale wind turbine blades by means of the length blade of 750kW wind turbine,some suggestions of modeling methods are put forward.

The research status of wind turbine blade is presented,as well as the three-dimensional modeling of the blade is discussed based on NURBS (Non-uniform Rational B-Spline).

PROPID is a computer program for design and analysis of horizontal axis wind turbine blades.

Analysis of geometric parameters of wind turbine blades section;

According to the design procedure of wind turbine blades,computing blade parameters based on the vortex theory,a kind of new program design method is offered to display the section and 3D model of wind turbine blades.
