According to Loth, a down-wind MoDaR (Morphing Downwind-Aligned Rotor) wind turbine is designed. At present, in order to improve the power generation performance of wind turbines, the diameter of the wind wheel is larger and larger, but the cost increase caused by the excessively large wind wheel is far greater than the yield of the wind power generation. MoDaR wind wheel is designed to solve this problem, MoDaR wind wheel is downwind wind wheel, blade is divided into two parts of the blade root tip and blade tip, two blade hinge connection. MoDaR wind wheel in the strong wind, the blade can be bent through the hinge to the wind direction, reducing the area swept the wind, so as to achieve the control of power generation and unit load effect. At present, the wind turbine of the mainstream MW-class unit achieves the effect of controlling power generation and unit load through pitch control. The design attempts to reduce the cost of the unit by controlling the area of ​​the wind turbine sweep, but this poses the following problems: 1. The blades must be light enough to withstand the load on the hinge and yaw bearings when the blades are folded back Too large; 2, to flow through the wind tower, the turbulence intensity increases, will make the unit load increased. Eric Loth said the rotor is likely not to be in commercial operation by 2025 because it is not necessary for the smaller turbines currently in operation. Welding wires are consumable electrodes used in the process of welding. They are made of various materials, such as carbon steel, stainless steel, aluminum, and flux-cored wire. Welding wires are designed to melt and join two or more metal pieces together when an electric current passes through them. They come in different diameters and compositions to suit different welding applications. Welding wires can be used with different types of welding processes, including MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and flux-cored arc welding Welding Wires,Welding Wire Price,Stainless Welding Wire,Stainless Steel Welding Wire Luoyang Golden Egret Geotools Co., Ltd , https://www.xtcmetalpowder.com
