6 FAQs about [Production of the tip of wind turbine blade PS surface]

What is the design process of a wind turbine blade?

The design process of a wind turbine blade can be divided into two steps: aerodynamic design and structural design. The aerodynamic design consists in the selection of optimal geometry of the blade external surface (blade geometry), which is defined by the airfoil family and the distributions of chord, twist angle and thickness.

What factors affect wind turbine blade design?

This paper presents parameters affecting the blade’s design in the wind turbine and includes a study on various factors like tip speed ratio, solidity, and twist in the blade. Loads acting on the blade are gravitational, bending and edge-wise, and centrifugal. Loads set critical limits of the design.

How to improve the structural design of wind turbine blades?

In order to compete with traditional power technologies and other energy sources, it is essential to use optimization techniques as part of the design process for wind turbine blades.
