Sentences with phrase «wind turbine blades because»

Not exact matches

But according to a source, it is the prevailing winds at these location that make the two blade turbines actually quite unsuitable for conditions in the region, because they can't stand up to the wind shears here.

Parker's initial blade prototype looked a lot like a wind turbine blade, but the end result (because of manufacturing, safety and operating concerns) was a hybrid between a standard ceiling fan blade and a wind turbine blade.

This could be because like wind turbines, the blades rotate at relatively slow speeds.

In addition to becoming more prone to catastrophic failure, the turbines also become less efficient at higher speeds because they become more like a wall than a rotor, blocking the wind from flowing past the rapidly rotating blades, says Asfaw Beyene, a professor of engineering at San Diego State University in California, who was not involved with the work.

«Throughout the wind - energy industry, drones are becoming more prevalent for site and blade inspection because they offer clear views of every angle of the turbines,» McIver said.

I believe that wind turbines detect lightning strikes because some repair, usually minor, is normally required to the area on the turbine blade where the strike occurred.

Offshore wind facilities, which are currently not in operation in the United States but may become more common, require larger amounts of space because the turbines and blades are bigger than their land - based counterparts.

In the early 2000s, wind engineers had begun to see the disadvantages of electrical sensors in monitoring the health of turbine blades and were experimenting with optical sensors because of their sensitivity to temperature and strain.

Making wind turbines larger is getting difficult, in part because they've have grown so large that the wind conditions at the highest point of the blades» sweep can be very different than those at the bottom.

The authors simply dismissed actual reported field CFs as irrelevant and not valid because they allegedly apply only to short, «low - power turbines with small diameters in slow - wind areas [less than 7 to 7.5 m / s annual winds]...» The authors, however, fail to explain why the higher power windmills with large diameter blades were not available before, if indeed this combination is wind energyís economic panacea.

Because the wind turbines would require a modest amount of spacing between them to allow room for the blades to spin, wind farms would occupy about 0.5 percent of all U.S. land, but this amount is more than 30 times less than that required for growing corn or grasses for ethanol.
