Siemens builds a very large wind turbine

Habré has repeatedly published news about the "green" energy. And although some nuances are very controversial (not always “green” energy is so “green”, often it is necessary to expend a huge amount of natural resources, including rare-earth elements) to obtain it. Nevertheless, there is a positive side to the spread of alternative energy technologies. Siemens is one of those companies that deals with such technologies. Recently, company representatives announced the imminent construction of a large wind turbine on the coast of England (one of the most likely regions).



To say that the turbine is "big" can not. Rather, the correct word would be “huge.” Indeed, the length of just one turbine blade is 75 meters, which automatically puts the upcoming turbine in first place in the world if you rank the “windmills” in size. With a wind speed of 10 m / s, the load on the turbine will be 181 tons of air (per second). At full load, the speed of the tips of the blades will be 290 km / h.

In this case, the blades can not be composite, they must be a single whole, and in this whole there can be no seams, joints, irregularities. To create the blade, developers use fiberglass, cork (to reduce the overall weight of the structure) and epoxy resin (to strengthen the structure). The giant system is called the B75, and its performance is also impressive.



The company will install a 6 megawatt turbine of its own production, and the turbine itself will be tested on the coast of Denmark. After passing the test (successful) turbines will be installed on the coast of England. Interestingly, the Airbus A380 wingspan is equal to the length of one blade. And if you imagine a pilot capable of navigating an airplane between the turbine blades, the plane passes freely.
